Selected AbstractsSOY ISOFLAVONE TABLETS REDUCE OSTEOPOROSIS RISK FACTORS AND OBESITY IN MIDDLE-AGED JAPANESE WOMENCLINICAL AND EXPERIMENTAL PHARMACOLOGY AND PHYSIOLOGY, Issue 2004Mari Mori Summary 1.,This study examines whether the supplementation of isoflavones (ISO) exerts beneficial effects on the bone mineral density (BMD) measured by dual energy X-ray absorptiometry (DEXA). 2.,Eighty-one healthy Japanese pre- and postmenopausal women were randomly assigned to the following two groups taking either ISO (100 mg) tablets (ISO group) or placebo tablets (P group) containing vitamins C (25 mg) and E (5 mg) daily for 24 weeks in a double-blind placebo controlled parallel design. 3.,Seventy women completed the intervention study (34 on ISO, 36 on P), only ISO group was proven to increase significantly BMD (P < 0.05 vs before) and to significantly decrease body fat measured by the DEXA (P < 0.0001 vs before and P < 0.05 vs P group), while BMI was maintained in ISO group despite significant BMI increase in P group. Thus, percent changes in BMI were significantly different between ISO and P groups (P < 0.05) 24 weeks after the intervention. 4.,This prospective DEXA study confirmed a long-term ISO supplementation, 100 mg/day could not only prevent menopausal bone resorption but also increase BMD and decrease body fat concomitantly with BMI reduction. Enough ISO supplementation may contribute to the risk reduction of osteoporosis and obesity and, thus to overall health promotion in menopausal women.

All adverse events were mild and involved transient symptoms that resolved without therapeutic intervention. TAS-108 was readily absorbed and plasma levels of TAS-108 steadily declined, apparently in a multi-exponential manner. Cmax and AUC0-12 were proportionally increased with increasing dose of TAS-108. The Cmax and AUC0-t of TAS-108 and its metabolite, deEt-TAS-108, were significantly increased to approximately 150% when TAS-108 was administered after a meal. Food did not affect the elimination half-life of TAS-108 or its metabolites. In this escalating dose-study of TAS-108, the drug was well tolerated by healthy post-menopausal Japanese women. The pharmacokinetics of TAS-108 indicated dose proportionality, and its bioavailability was significantly increased by food intake. [source] Trends in Benign Breast Tumors in Japanese Women, 1973,1995: Experience of Hiroshima Tumor Tissue RegistryCANCER SCIENCE, Issue 6 2002Koji Arihiro Although some benign breast lesions such as multiple intraductal papilloma have been pointed out as a risk factor for breast cancer, there is little documentation about trends in the incidence of benign tumors of the breast in Japanese women. The author conducted an epidemiological study using data abstracted from the Hiroshima Tumor Tissue Registry file, which includes cases of malignant and benign neoplasms in Hiroshima prefecture between 1973 and 1995. A total of 17 064 cases of female breast tumor were registered in the file between 1973 and 1995. The registration rate for fibroadenoma of the female breast was 19.5 among females and peaked during the 5-year period 1983,1987, while the fibroadenoma registration rate in Hiroshima gradually decreased between 1988 and 1995. The registration rate for intraductal papilloma has risen substantially in Hiroshima, with about a 5-fold increase among females between 1973 and 1995. The mean proportion of fibroadenoma cases accompanied by malignant tumors of the breast was 1.85%, and there was no significant change in the mean proportion between 1973 and 1995 (P=0.17). On the other hand, the mean proportion of intraductal papilloma cases accompanied by malignant tumors of the breast gradually rose with about a 14-fold increase among females between 1973 and 1995. The significance of intraductal papilloma as a risk factor for breast cancer may have increased. [source] Non-pigmenting fixed drug eruption caused by allylisopropylacetylureaCONTACT DERMATITIS, Issue 4 2003Yukikazu Numata An unusual case of a non-pigmenting fixed drug eruption caused by allylisopropylacetylurea is reported. Several hours after taking an analgesic (New Kaiteki A®), a 30-year-old Japanese woman, who had experienced similar eruptions several times after taking other analgesics, developed numerous variously sized, itchy, round-to-oval erythematous eruptions on the trunk and extremities. After she discontinued taking this drug, all such eruptions resolved within 2 weeks, without leaving postinflammatory pigmentation. Patch testing with New Kaiteki A® itself and one of its active ingredients, allylisopropylacetylurea, on lesional skin, but not on uninvolved skin, showed positive erythematous reactions after 2 days. [source] EARLY GASTRIC CANCER WITH WIDESPREAD DUODENAL INVASION WITHIN THE MUCOSADIGESTIVE ENDOSCOPY, Issue 3 2010Tsutomu Namikawa We report a rare case of early gastric cancer confined to the mucosal layer with extensive duodenal invasion, curatively removed with distal gastrectomy. An 84-year-old Japanese woman was referred to our hospital with gastric cancer. A barium meal examination and esophagogastroduodenoscopy revealed an irregular nodulated lesion measuring 6.5 x 5.5 cm in the gastric antrum and an aggregation of small nodules in the duodenal bulb. A biopsy specimen showed well-differentiated adenocarcinoma. The patient underwent distal gastrectomy with partial resection of the duodenal region containing the tumor and regional lymph node dissection, with no complication. Histological examination of the resected tissue confirmed well-differentiated adenocarcinoma limited to the mucosal layer and without lymph node metastasis. The cancer extended into the duodenum as far as 38 mm distant from the pyloric ring, and the resected margins were free of cancer cells. Gastric cancer located adjacent to the pyloric ring thus has the potential for duodenal invasion, even when tumor invasion is confined to the mucosal layer. In such cases, care should be taken during examinations to detect duodenal invasion, and the distal surgical margin must be negative given sufficient duodenal resection. [source] Large mucosa-associated lymphoid tissue lymphoma simulating multiple polypoid lesions at the cecum and rectumDIGESTIVE ENDOSCOPY, Issue 4 2001Yutaka Onishi Herein we describe a case of mucosa-associated lymphoid tissue (MALT) lymphoma of the cecum and rectum with the Leser,Trélat sign. A 76-year-old Japanese woman was admitted to the Harima Hospital of Ishikawajima-harima Heavy Industries, Health Insurance Society for hematochezia. Colonoscopy showed two large elevated tumors, one in the cecum and the other in the rectum. Biopsy was not diagnostic. Endoscopic snare loop biopsy specimens from both tumors were diagnosed as MALT lymphoma. After staging to IIE, the patient underwent surgery. Macroscopically, the cecal tumor was elevated with a large and deep depressed region, measuring 40 × 35 mm. The rectal lesion was a large elevated tumor, measuring 80 × 70 mm. Histologically, both tumors were diagnosed as MALT lymphoma and there was no lymph node metastasis. The patient received chemotherapy and there is no evidence of recurrence 1 year after surgery. We present this case to show that colorectal MALT lymphoma can present as a large tumor, even in early clinical stages, that multiple lesions should be anticipated and that surgical treatment is needed in these cases. [source] Nodule-aggregating lesion of the ileum: Report of a case and a review of the literatureDIGESTIVE ENDOSCOPY, Issue 3 2001Norikazu Sakamoto We describe here a rare case of nodule-aggregating lesion of the terminal ileum detected by colonoscopy. An 82-year-old Japanese woman was admitted to our hospital with diarrhea. Colonoscopy revealed a flat elevated tumor with conglomerated nodular surface involving the entire circumference of the terminal ileum, suggesting a nodule-aggregating lesion. Magnifying the colonoscopic view showed the branch-like or gyrus-like pits. On biopsy, the tumor was diagnosed as a tubulovillous adenoma. Retrograde ileogram using a colonoscope revealed an elevated tumor with nodular irregularity, measuring 5 cm in length. Ileocecal resection was performed. Macroscopically, the tumor in the terminal ileum, 8 cm distant from the ileocecal valve, showed a nodule-aggregating lesion, measuring 44 × 60 × 6 mm in size. Histologically, the tumor showed a focal carcinoma in tubulovillous adenoma. To our knowledge, this is the fifth case of early cancer of the ileum in Japan, and the first case of nodule-aggregating lesion of the ileum detected by colonoscopy in the world. [source] Successful Endoscopic Band Ligation for Treatment of Postpolypectomy HemorrhageDIGESTIVE ENDOSCOPY, Issue 4 2000Yohei Mizuta We describe a case of large pedunculated tubulovillous adenoma of the stomach associated with postpolypectomy hemorrhage, which was successfully treated by endoscopic band ligation. The case study involved a 60-year-old Japanese woman with a pedunculated polyp with a slightly lobular surface, measuring 25 mm in diameter. It was detected on the posterior wall of the middle body of the gastric remnant. The lesion was diagnosed as a tubulovillous adenoma by a biopsy specimen and treated by endoscopic polypectomy using the detachable snare to prevent postpolypectomy hemorrhage. There was no episode of immediate postpolypectomy hemorrhage, but hematemesis occured 18 h after the excision. Endoscopic examination of the stomach showed the mark left by bleeding on the cutting surface and the absence of the detachable snare. Endoscopic intervention by rubber band ligation was performed to prevent the recurrent bleeding. Complete hemostasis was obtained and no serious complications occured. [source] Erythema multiforme-like lesions associated with lesional infiltration of tumor cells occurring with adult T-cell lymphoma/leukemiaINTERNATIONAL JOURNAL OF DERMATOLOGY, Issue 4 2008Tomoyuki Ohtani MD A 66-year-old Japanese woman visited our hospital with a complaint of multiple papules on her trunk and extremities. She had a past medical history of appendicitis and blood transfusion 40 years earlier. For the last 10 years, she had noticed multiple, gradually enlarging papulonodular lesions with surrounding erythema on her trunk and extremities. ,Physical examination revealed multiple, violaceous papules or nodules, less than 10 mm in diameter, with surrounding erythema on her trunk and extremities (Fig. 1). The results of routine laboratory examinations, including blood count, liver function, renal function, serum calcium, and lactate dehydrogenase, were within the normal range. The peripheral blood picture showed a small population of atypical lymphocytes below 1% of the total white blood cells. Human T-cell lymphotropic virus type I (HTLV-I) serology was positive. A microscopic examination of a biopsy specimen from a nodule on the abdomen demonstrated diffuse infiltration of large pleomorphic T cells in the upper and middle dermis, although highly atypical lymphocytes, so-called flower cells, could not be recognized. Infiltrating lymphocytes were positive for CD2, CD3, CD4, CD5, CD7, and CD45, but negative for CD8 and CD20, immunohistologically. Bone marrow biopsy also demonstrated the infiltration of lymphocytes expressing CD2, CD3, CD4, CD5, and CD7, but not CD25. Southern blot analysis of the infiltrating cells in the skin revealed an integration of HTLV-I proviral DNA in T cells. Clonal T-cell receptor , gene rearrangement was detected in skin and bone marrow biopsies. No abnormal mass or bone defect was detected by chest or abdominal computed tomographic scanning, systemic gallium-67 citrate scintigraphy, or chest radiography. On the basis of these data, the patient was diagnosed with smouldering-type adult T-cell lymphoma/leukemia. Figure 1. Clinical features of adult T-cell lymphoma/leukemia (ATL) skin lesions. Crusted, target-like, dark-red plaques on the lower legs ,The patient was started on topical steroid and electron beam radiation therapy (27 Gy/14 days). Five days after the start of irradiation, she noticed multiple patches of edematous erythema appearing on the trunk and extremities (Fig. 2). As it was initially suspected that these newly emerging erythema multiforme or toxic eruptions were caused by irradiation, therapy was interrupted. Anti-herpes simplex virus antibody was not checked because no typical herpes simplex lesions were noticed. The patient was not taking any systemic drugs. A skin biopsy was taken from a representative lesion on the chest. The pathologic specimen showed epidermotropism, liquefaction degeneration in the basal layer, marked edema, and dense infiltration of mononuclear cells in the upper dermis. Infiltrating cells possessed abundant cytoplasm and large pleomorphic nuclei with distinct nucleoli (Fig. 3). These findings were consistent with the histopathologic findings of erythema multiforme, except for the atypical lymphoid cell infiltration. Immunohistochemical staining demonstrated that the phenotype of the skin-infiltrating cells was identical to that of the atypical cells in the initial lesions. As the eruptions did not disappear in spite of the interruption of radiation, total skin irradiation was restarted. After completion of therapy, both the erythema multiforme-like lesions and the initial adult T-cell lymphoma/leukemia nodules on the trunk and extremities had resolved, leaving brown pigmentation. The patient has been free of any recurrence of skin lesions or systemic symptoms for 6 years after the completion of total skin irradiation. Figure 2.

She presented with an asymptomatic brown macule located on the right axilla of 2 months' duration. The smooth macule was 2 cm in diameter with a sharp demarcation (Fig. 1A). Figure 1. Photographs of skin lesions in two patients. (A) Case 1. Well-circumscribed brown macule without an active red border in the central portion of the right axilla. (B) Case 2. Symmetric distribution of brown macules without an active red border in the popliteal fossae Case 2 was a 62-year-old Japanese man. He presented with asymptomatic, symmetric, gray,brown macules located on the groin, axillae, and popliteal region of 6 months' duration. The smooth macules were several millimeters to centimeters in diameter and sharply demarcated (Fig. 1B). Oral or nail lesions, previous inflammatory processes in affected areas, and internal malignancies were absent. A causal relationship with drugs, recent sun exposure, or trauma could not be identified. Findings for work-up, including blood cell count, fasting blood sugar levels, liver function, serum electrolyte levels, serum electrophoresis, urinalysis, antinuclear antibodies, and serological examinations for human hepatitis viruses and syphilis, were within normal limits or negative. The lesions gradually disappeared without medication within 6 months. Biopsy specimens showed a lymphocytic infiltrate with basal vacuolar changes and prominent melanin incontinence in the upper dermis (Fig. 2A). The band-like lymphocytic infiltrate was moderate in Case 1 and mild in Case 2. Immunohistochemistry showed infiltrative CD8+ T lymphocytes with keratinocytic damage, indicating cytotoxic injury of the keratinocytes (Fig. 2B). Both the epidermis and the upper dermis contained CD1a+ cells (Fig. 2C). The keratinocytes focally and weakly expressed HLA-DR (Fig. 2D). These findings were identical in samples from both patients.

They share some common histopathologic features. Methods We describe a 72-year-old Japanese woman with apocrine carcinoma of the vulva and local lymphatic metastasis. Results The patient presented with a bruise on her inguinal area. Physical examination revealed a 4 cm × 7 cm, dark-red, irregularly elevated tumor on the left labium majora. Dome-shaped, flesh-colored, small papulovesicles were scattered on the abdomen, accompanied by erythema and induration. The lesion showed a band-like arrangement. General examination revealed multiple bone metastases, particularly in the spine. Microscopic examination revealed a moderately differentiated adenocarcinoma with signet ring cells. A few pagetoid clear cells were present in the hypertrophic epidermis. The peripheral papulovesicles demonstrated the same histopathologic view as in inflammatory and telangiectatic, metastatic breast carcinoma. Tumor cells were positive for various ductal and glandular markers. Estrogen and progesterone receptors were not expressed. Ultrastructural findings suggested differentiation towards apocrine or mammary glands because of the presence of an apocrine process and electron-dense mucous granules. The patient died in spite of combination chemotherapy and irradiation therapy. Conclusions We report a rare case of apocrine carcinoma of the vulva in a band-like arrangement with local lymphatic metastasis which showed the clinical and histopathologic characteristics of inflammatory and telangiectatic carcinoma. [source] A Japanese case of Kindler syndromeINTERNATIONAL JOURNAL OF DERMATOLOGY, Issue 4 2000Yasushi Suga MD A 25-year-old Japanese woman presented with contracture of the fingers and toes, and difficulty in opening her mouth. Her grandparents are first cousins, but none of the other members of the family are affected. Bulla formation started at birth on areas of the skin that received pressure, and in infancy and early childhood the lesions were limited only to the acral areas. She also had bilateral, incomplete syndactylies involving all web spaces ( Fig. 1a). The formation of blisters ceased after the age of 15 years, but a generalized progressive poikiloderma then appeared with accompanying cutaneous atrophy of the skin of the neck, trunk, and extremities ( Fig. 1b). The patient experienced mild photosensitivity of the face and neck. At age 18 years, surgical removal of the webbing of all her fingers was performed. Oral examination showed atrophy of the buccal mucosa, and an inability to fully open the mouth. The patient also suffered from poor dentition and easily bleeding gums, but had no symptoms of esophageal dysfunction. Figure 1. Clinical manifestations of the patient with Kindler syndrome. (a) Dorsal surface of the patient's hands. Note the marked cutaneous atrophy with a severely wrinkled appearance on the dorsal surface of the hands, as well as the proximal fusion of the fingers. (b) Lower left leg of the patient. Atrophic thinning of the skin and poikiloderma with reticular pigmentation are evident Histology of separate biopsy specimens, taken from the poikilodermatous pretibial and trunk skin, showed classical features of poikiloderma, namely epidermal atrophy with flattening of the rete ridges, vacuolization of basal keratinocytes, pigmentary incontinence, and mild dermal perivascularization ( Fig. 2a). Interestingly, dyskeratotic cells ( Fig. 2b) and eosinophilic rounded bodies (colloid bodies) ( Fig. 2c) were frequently found at the basal keratinocyte layer and in the upper dermis, respectively. Pigment was also present in the upper epidermis. Figure 2. Hematoxylin and eosin staining of a biopsy specimen taken from pretibial skin. (a) Epidermal atrophy with flattening of the rete ridges. Note the dyskeratotic cells (arrowheads) and vacuolar degeneration of the basal layer in the epidermis. Bar = 50 ,m. (b) Higher magnification of dyskeratotic cells (arrowheads). Bar = 10 ,m. (c) Higher magnification of colloid bodies (arrowheads) in the superficial dermis. Bar = 10 ,m To rule out the possibility of a congenital epidermolysis bullosa, ultrastructural and immunofluorescence studies were performed. Ultrastructural studies demonstrated the reduplication of the basal lamina with branching structures within the upper dermis and cleavage between the lamina densa and the cell membrane of the keratinocytes ( Fig. 3a). The numbers of associated anchoring fibrils did not seem to be reduced, and colloid bodies and dyskeratotic cells were detected. Immunofluorescence studies with the antibody against type VII collagen (LH 7 : 2) were subsequently carried out. The results showed extensive broad bands with intermittently discontinuous and reticular staining at the dermo-epidermal junction (DEJ) ( Fig. 3b), whereas a linear distribution is typically seen in healthy tissue (data not shown). Interestingly, direct immunofluorescence studies revealed intracellular accumulation of immunoglobulin G (IgG), IgM, IgA, and C3 in colloid bodies under the basement membrane ( Fig. 3c). Figure 3. Ultrastructural and immunohistochemical findings of the patient with Kindler syndrome. (a) Ultrastructural study of the dermo-epidermal junction.

Background:, Lymphangioleiomyomatosis (LAM) can occur as in isolated form (sporadic LAM) or as a pulmonary manifestation of tuberous sclerosis complex (TSC) (TSC-associated LAM). Recent studies, however, revealed that both forms of LAM are genetically related but that sporadic LAM is a distinct clinical entity caused by somatic mutations of TSC2 (not TSC1) rather than a forme fruste of TSC carrying either of the TSC1 or TSC2 germline mutations. Method:, Case presentation and in-depth molecular and histopathological examinations. A 34-year-old Japanese woman was diagnosed as having pulmonary lymphangioleiomyomatosis (LAM) when bilateral pneumothoraces were surgically treated in 1992. Although slowly progressive renal disfunction was observed due to bilateral multiple renal cysts during the past 4 years, she had no other clinical features of TSC and was diagnosed as having sporadic LAM with multiple renal cysts of undetermined aetiology. Her subsequent clinical course was complicated by an endobrochial carcinoid tumour, which eventually resulted in her death in June 1999 due to massive haemoptysis. Results:, Postmortem examination revealed the presence of LAM lesions in the lungs, mediastinal lymph nodes, kidneys and uterus. Diffuse renal LAM lesions are presumed to generate multiple renal cysts by constricting the nephron rather than epithelial hyperplasia obstructing lumina, which is analysis of the TSC genes demonstrated that she did not have TSC2/PKD1 contiguous gene syndrome but had a TSC1 germline mutation (Sato T et al. J Hum Genet 2002; 47: 20,8) that had occured de novo. Conclusion:, This patient therefore illustrates that clinical manifestations of TSC are sufficiently diverse as to allow a forme fruste of TSC that mimics sporadic LAM and that TSC1 mutation can cause multiple renal cysts resulting in renal failure. [source] Marginal zone B-cell lymphoma of minor salivary gland representing tumor-forming amyloidosis of the oral cavity.JOURNAL OF ORAL PATHOLOGY & MEDICINE, Issue 5 2006A case report We report here a case of mucosa-associated lymphoid tissue (MALT)-type lymphoma arising from the minor salivary gland of the oral cavity exhibiting tumor-forming amyloidosis. The patient was a 64-year-old Japanese woman who presented with 4-year history of a left soft palate mass. Despite multiple and multifocal recurrences including the lip, soft palate, tongue, oral base and vocal code and soft palate, the tumor remained localized in the upper aerodigestive tract, and the patient did not develop multiple myeloma during the course of disease. Histologically, the majority of the lesion was occupied by amyloid deposition. Only the periphery of the lesion contained numerous plasmacytoid cells, along with occasional centrocyte-like cells. In addition, lymphoepithelial lesion and follicular colonization were noted. The present case indicates that primary minor salivary gland MALT-type lymphoma appears to be the cause of tumor-forming amyloidosis of the upper aerodigestive tract including the larynx. [source] A decade-long sour-taste sensation successfully treated with a proton-pump inhibitorJOURNAL OF ORAL REHABILITATION, Issue 10 2005N. MANTANI summary We report a case study of a 54-year-old Japanese woman who persistently suffered from a sour-taste sensation in her mouth for 10 years, and was treated with a proton-pump inhibitor (PPI). She found sour-tasting meals irritable, and after eating such meals the sour-taste sensation worsened. She also complained of eructation and regurgitation. Upper gastrointestinal (GI) endoscopy showed duodenal erosion, superficial gastritis, and erosive oesophagitis. After 2 weeks of PPI therapy (lansoprazole, 30 mg day,1) the sour taste subjectively decreased to 70%, and after 6 weeks the symptoms disappeared. In addition to increased sensitivity of the mouth, gastro-oesophageal reflux might have created her obstinate sour-taste sensations. It is suggested that in such cases PPI therapy should be attempted. [source] Pulmonary capillary hemangiomatosis incidentally detected in a lobectomy specimen for a metastatic colon cancerPATHOLOGY INTERNATIONAL, Issue 6 2006Suzuko Moritani Pulmonary capillary hemangiomatosis is a rare vascular proliferative disease of unknown etiology. The common clinical features are slowly progressive and finally fatal pulmonary hypertension. The clinical diagnosis is usually difficult. Because most reported cases are of autopsy, little is known about its incipient lesion and natural history. Presented herein is a case of pulmonary capillary hemangiomatosis incidentally detected in a surgically resected lung for a metastatic colon cancer. The patient was a 60-year-old Japanese woman with a history of sigmoid colon cancer 3 years previously. The patient had undergone a right lower lobectomy for a metastatic tumor in the hilar region and a thoracoscopic tumorectomy of the peripheral area of the left upper lobe. Except for an episode of hemoptysis 2 weeks prior to the lung surgery, there were no other clinical symptoms characteristic of pulmonary capillary hemangiomatosis. The non-tumor area of right lower lobe showed multiple foci of capillary proliferation affecting alveolar walls, interlobular septa and pleura associated with patchy hemorrhage. There was a minor degree of vascular and bronchial involvement by capillary proliferation. It is suggested this particular case is an incidentally detected clinically incipient stage of pulmonary capillary hemangiomatosis. Passive congestion secondary to metastatic colon cancer in the hilar region may have contributed to the pathogenesis of this lesion. [source] Phlebosclerotic colitis coincident with carcinoma in adenomaPATHOLOGY INTERNATIONAL, Issue 10 2003Yasuhiko Kimura Phlebosclerosis of the colon is a rare disease characterized by a thickening of the wall of the colon with fibrosis, hy-alinization and calcification to the affected veins. These symptoms result in a type of ischemic colitis known as phlebosclerotic colitis. A case of phlebosclerotic colitis coincident with carcinoma in adenoma is reported. A 74-year-old Japanese woman was admitted to hospital because of a mass in her right lower abdomen. Abdominal computed tomography examination revealed linear calcifications in the wall of the cecum and the ascending colon. Colonoscopy revealed dark purple mucosa with multiple ulcers in the cecum and the ascending colon. Biopsy specimens showed a marked hyalinous thickening of the wall of small blood vessels in the mucosa. Phlebosclerotic colitis was suspected because of negative results with amyloid stain. Alternative ileocolic angiography showed the serpentine of the peripheral nature blood vessels and pooling at the late venous phase. Microscopic examination of the surgically resected colon revealed mucosal and submucosal fibrosis, and a thickening of the venous wall with fibrosis, hyalinization and calcification from the mucosa to the serosa, which caused a marked luminal narrowing. A small polypoid lesion was also found in the affected region and was diagnosed histologically as carcinoma in adenoma. To our knowledge, this is the first reported case of phlebosclerotic colitis complicated by carcinoma. [source] Esophageal anthracosis: Lesion mimicking malignant melanomaPATHOLOGY INTERNATIONAL, Issue 7 2002Tetsuya Murata A case of anthracosis of the esophagus is reported. The patient was a previously healthy 69-year-old Japanese woman. A black and slightly elevated lesion was detected in her esophagus by upper gastroesophageal fiberoscopic examination. Endoscopically, the lesion looked like malignant melanoma. Thoracic esophagotomy was then performed. Histological examination revealed a pigmented lesion beneath the mucosal epithelial layer. The lesion consisted of an aggregation of histiocytes containing an abundance of tiny black pigments. A few mature lymphocytes and plasma cells were also evident in the periphery of the lesion. Histologically, these findings looked like lymph nodes in the pulmonary hilus; however, no lymph nodal structure was evident in the esophageal wall. Traction diverticula were also noted in the pigmented lesion. The patient has remained well without disease for 9 months since the surgery. Although anthracosis is a rare condition in the esophagus, the present case gave warning to pathologists and clinicians that it does indeed occur. Endoscopists and pathologists should differentiate anthracosis from malignant melanoma because the treatment and outcome are quite different for each. [source] Low-grade renal cell carcinoma arising from the lower nephron: A case report with immunohistochemical, histochemical and ultrastructural studiesPATHOLOGY INTERNATIONAL, Issue 12 2001Masako Otani Most renal cell carcinomas (RCC) are composed of clear cells with sinusoid-like vasculatures and originate from the proximal tubule. On the other hand, collecting duct carcinoma (CDC) and chromophobe RCC are thought to originate from the lower nephron. In the present study, we present a case of unusual RCC. The patient was a 68-year-old Japanese woman who had developed general fatigue with hematuria. Computed tomography revealed a left renal tumor suggesting sarcoma. The resected tumor was located in the renal parenchyma, measuring 12 × 10 × 8 cm in size. Histologically, the tumor consisted principally of cuboidal cells forming parallel or radiating arrays, continuous with the spindle-shaped cells. Most parts of the tumor showed hemorrhagic necrosis. Immunohistochemically, tumor cells were positive for high molecular weight cytokeratins, vinculin, vimentin, CD15 and epithelial membrane antigen, and showed affinities with some kinds of lectins. N- and E-cadherins and , -catenin were diffusely positive in tumor cells. Nuclear positivity for Ki-67 and p53 protein were approximately 2.0 and 1.7%, respectively. Considering its morphological and histochemical natures, this tumor is considered to have originated from the lower nephron, which is unique for a tumor of low-grade malignancy. [source] Phosphoglyceride crystal deposition diseasePATHOLOGY INTERNATIONAL, Issue 12 2000Katsutoshi Miura An extremely rare phosphoglyceride deposition disease is reported. A healthy 62-year-old Japanese woman suffered from tumors that repeatedly appeared in injured soft tissues for more than 20 years. No immunologic disorders or abnormal laboratory data were found. Histology showed foreign body granulomas consisting of macrophages surrounding yellowish-white crystals. The crystals were weakly positive by von Kossa's method, were dissolved in 30% acetic acid with gas, and were easily dissolved in 0.1 N NaOH or potassium hydroxide, losing their crystal structure. Using a scanning electron microscopy X-ray microanalyzer, phosphorus and calcium peaks were detected. Phosphoglycerides were detected by microscopic infrared spectrophotometry and microsampling mass spectrometry. The gold hydroxamic acid method for detecting phosphoglyceride showed strong positive staining in the crystals. Based on the above analyses, the deposited crystals were regarded as phosphoglyceride, which bound calcium as a counter ion. The crystals tended to be deposited at sites of injury, where macrophages had accumulated. The patient had received many injections of a medicine made from alcohol extract from bovine liver. We suspect that this medicine was related to the cause of the deposition as the deposition repeatedly appeared at the site of the injections.

The patient complained of abnormal vaginal bleeding of 10 days' duration. On admission a uterine corpus mass and high serum AFP concentration (31950 ng/mL) was noted. There was no tumorous lesion in any other organ radiographically and endoscopically. Histologically, the biopsy specimen taken from the uterine mass showed a poorly differentiated endometrial carcinoma and a radical hysterectomy was subsequently performed. The postoperative serum AFP value transiently decreased with chemotherapy, however, lung metastases were found and the patient died 12 months following surgery. The resected uterus had a necrotic tumor, 6 × 5 × 4 cm in size, filling the endometrial cavity, characterized by exophytic growth with infiltration in the myometrium. Histologically, the tumor was composed of the main medullary carcinoma area with microcysts and admixed small areas of well-differentiated endometrioid adenocarcinoma, accompanied by a smooth transition with one another. In both the areas, the tumor cells had immunoreactive AFP, alpha-1-antitripsin, albumin, transferrin, carcinoembryonic antigen, CA19-9, and epithelial membrane antigen. There was no histologic evidence for a germ cell tumor. Based on these findings, this uterine corpus tumor was regarded as hepatoid variant of endometrial carcinoma. Although the histogenesis remains controversial, we assume the hypothesis that the tumor may arise in the endometrium per se in association with abnormal differentiation of muellerian duct elements. [source] Solitary squamous cell papilloma of the lung in a 40-year-old woman with recurrent laryngeal papillomatosisPATHOLOGY INTERNATIONAL, Issue 5 2000Hidekazu Harada A rare case of recurrent respiratory papillomatosis (RRP) is reported with a review of the literature. A 40-year-old Japanese woman had suffered from RRP since 1 year of age. She developed a pulmonary squamous papilloma with a thin-walled cavity, which was suspected as being lung carcinoma. The trachea and bronchi around the tumor were intact, and no malignant transformation was present. Two types of human papillomavirus, 6 and 16, were detected, both in the laryngeal and pulmonary papillomas by in situ hybridization and the polymerase chain reaction method. To date, only 40 cases of juvenile laryngeal papilloma with pulmonary involvement have been reported in the English literature. [source] Acute confusional state after designer tryptamine abusePSYCHIATRY AND CLINICAL NEUROSCIENCES, Issue 2 2007MASANARI ITOKAWA md Abstract A 23-year-old Japanese woman was brought to the emergency department about 6.5 h after taking liquid and later a half tablet purchased on the street. About 4.5 h prior to presentation, she displayed excited and disorganized behavior. On examination, she was not alert or oriented, with a Glasgow Coma Scale score of 13, did not answer any questions from doctors while smirking and looking around restlessly, and sometimes exhibited echolalia, imitating the speech of doctors. She was given intravenous infusion of fluid for 8 h, then discharged. Gas chromatography-mass spectrometry of urine revealed 5-methoxy-diisopropyltryptamine, 5-methoxy-N-methyltryptamine and an unidentified tryptamine. Identifying chemical products based solely on information of users is insufficient, and urinalysis is necessary in cases potentially involving designer drugs. [source] Epithelioid sarcoma presenting as pulmonary cysts with cancer antigen 125 expressionRESPIROLOGY, Issue 6 2006Eiki KIKUCHI Abstract: A 39-year-old Japanese woman presented with a swollen right hand and a right-sided pneumothorax. Chest CT revealed bilateral multiple pulmonary thin-walled cysts measuring ,1 cm in diameter and small nodules. An initial skin biopsy led to a misdiagnosis of metastatic adenocarcinoma, as tumour cells were positive for cytokeratin, epithelial membrane antigen, carcinoembryonic antigen and cancer antigen 125. However, chemotherapy proved ineffective, and the skin biopsy was repeated. A final diagnosis of epithelioid sarcoma (ES) was made. Open lung biopsy showed that the pulmonary nodules represented metastases of ES. Although the pulmonary cyst walls did not contain tumour cells, bronchiolar wall adjacent to the cysts had been infiltrated by tumour cells. These findings suggested that pulmonary cysts, a rare form of pulmonary metastases from soft tissue sarcomas, had developed through a ball-valve effect of metastatic tumour in small airways. However, presence of cancer antigen 125 hindered obtaining a correct diagnosis of ES. [source] Ulcerative pigmented squamous cell carcinoma in a 101-year-old Japanese womanTHE JOURNAL OF DERMATOLOGY, Issue 4 2009Yuichi YOSHIDA ABSTRACT Pigmented squamous cell carcinoma is a rare variant of squamous cell carcinoma. We report a case of pigmented squamous cell carcinoma with dermoscopic examination probably arisen from actinic keratosis in a 101-year-old woman who was surgically treated under general anesthesia. In addition, we discuss indications of general anesthesia in elderly patients with skin cancer, differential diagnosis and dermoscopic features of pigmented squamous cell carcinoma. [source] Reverse latissimus dorsi musculocutaneous flap for reconstruction of lumbar radiation ulcerTHE JOURNAL OF DERMATOLOGY, Issue 8 2007Sei-ichiro MOTEGI ABSTRACT The surgical treatment of large, deep defects on the midline of the lower back or lumbar area comprises difficult reconstructive challenges. Various flaps have been designed to reconstruct the defect area. We herein report a 70-year-old Japanese woman with a large, deep ulcer in the midline of the lower back, caused by postoperative radiation therapy for eccrine porocarcinoma. The ulcer was successfully treated with surgical debridement followed by reverse latissimus dorsi musculocutaneous flap. This flap is reliable and useful for reconstruction of a large, deep midline defect of the lower back, having large and bulky tissue with a sufficient blood supply. [source] Case of localized bullous pemphigoid with unique clinical manifestations in the lower legsTHE JOURNAL OF DERMATOLOGY, Issue 7 2007Kazuhiro KOHROH ABSTRACT We report the case of a 71-year-old Japanese woman who presented with persistent band-like erosions in the lower legs. Histological examination suggested subepidermal blister formation. Direct and indirect immunofluorescence studies revealed tissue-deposited and circulating immunoglobulin G autoantibodies against the basement membrane. Western blotting revealed autoantibodies to BP230, but not to BP180. Based on these findings, the patient was diagnosed as having a localized type of bullous pemphigoid. We suggest that the unique clinical manifestations in this patient could be attributable to bacterial or fungal infection, and/or mechanical trauma, such as the pressure of her socks. [source] |
