Ulcerative Lesions (ulcerative + lesion)
Selected AbstractsUnifocal Langerhans cell histiocytosis of the oral mucosaJOURNAL DER DEUTSCHEN DERMATOLOGISCHEN GESELLSCHAFT, Issue 7 2009Susanna Fistarol Summary A 24-year-old man was admitted for a painful gingival ulcer. Histology and immunohistochemistry of a lesional biopsy revealed the diagnosis of Langerhans cell histiocytosis (LCH). To rule out multifocal disease, a complete staging was performed. There was no evidence of bony lesions or any other organ involvement. The diagnosis of LCH restricted to the oral mucosa was established. The complete oral lesion was ablated by CO2 laser and subsequently treated topically with triamcinolone acetonide. The patient is still in remission after one year of follow-up. LCH confined to the oral mucosa is rare. It presents usually as an inflammatory or ulcerative lesion, easily leading to misinterpretation and delayed diagnosis. Patients with limited unifocal mucocutaneous disease, as in the present case, usually have an excellent prognosis. However, the oral lesion may represent an early sign of LCH, predating and progressing to an aggressive life-threatening multiorgan disease. [source] ENDOSCOPIC SUBMUCOSAL DISSECTION FOR EARLY GASTRIC CANCER: TECHNICAL FEASIBILITY, OPERATION TIME AND COMPLICATIONS FROM A LARGE CONSECUTIVE SERIESDIGESTIVE ENDOSCOPY, Issue 1 2005Ichiro Oda Background:, Endoscopic mucosal resection (EMR) is a recognized treatment for early gastric cancer (EGC). One-piece resection is considered to be a gold standard of EMR, as it provides accurate histological assessment and reduces the risk of local recurrence. Endoscopic submucosal dissection (ESD) is a new technique developed to obtain one-piece resection even for large and ulcerative lesions. The present study aims to identify the technical feasibility, operation time and complications from a large consecutive series. Methods:, We reviewed all patients with EGC who underwent ESD using the IT knife at National Cancer Center Hospital in the period between January 2000 and December 2003. Results:, During the study period of 4 years we identified a total of 1033 EGC lesions in 945 consecutive patients who underwent ESD using the IT knife. We found a one-piece resection rate (OPRR) of 98% (1008/1033). Our OPRR with tumor-free margins was 93% (957/1033). On subgroup analysis it was found to be 86% (271/314) among large lesions (, 21 mm) and 89% (216/243) among ulcerative lesions. The overall non-evaluable resection rate was 1.8% (19/1033). The median operation time was 60 min (range; 10,540 min). Evidence of immediate bleeding was found in 7%. Delayed bleeding after ESD was seen in 6% and perforation in 4% of the cases. All cases with complications except one were successfully treated by endoscopic treatment. Conclusion:, The present study shows the technical feasibility of ESD, which provides one-piece resections even in large and ulcerative EGC. [source] Gemcitabine induced digital ischaemia and necrosisEUROPEAN JOURNAL OF CANCER CARE, Issue 3 2010A. HOLSTEIN md HOLSTEIN A., BÄTGE R. & EGBERTS E.-H. (2010) European Journal of Cancer Care19, 408,409 Gemcitabine induced digital ischaemia and necrosis A 70-year-old woman presented with a 7-day history of severe pain, paresthesia, oedema, acrocyanosis and punctate haemorrhagic lesions on her fingertips. The complaints began 2 days after the second cycle of a first-line chemotherapy consisting of cisplatin or carboplatin, and gemcitabine due to advanced urothelial carcinoma. At the fingertips of both hands, haemorrhagic and partly ulcerative lesions were found; these were attributed to vascular toxicity of gemcitabine. Therapeutically sympathicolysis by bilateral blockade of the brachial plexus was performed, accompanied by intravenous administration of the prostacyclin analog iloprost, fractionated heparin subcutaneously and oral therapy with corticosteroids and aspirin. Digital amputation could be avoided. Acral ischemia is a rare but probably underreported adverse effect of gemcitabine therapy and a potential source of misdiagnosis. [source] Febrile Ulceronecrotic Mucha-habermann Disease: a Rare, Severe VariantJOURNAL OF CUTANEOUS PATHOLOGY, Issue 1 2006Michele M. Thompson A 56 year old Hispanic man presented with extensive ulcerative skin lesions, involving his lower trunk, groin and upper legs, severe pain and a temperature of 38.7 degrees Celsius. He was admitted to the Medical Intensive Care Unit for empiric intravenous antibiotics. Several biopsies were performed. In the following days his condition worsened and ulcerative lesions involved nearly all of his skin. Previous biopsies were consistent with pityriasis lichenoides et varioliformis acuta (PLEVA), however, neither this, nor others in the histological differential diagnosis, fit his severe and worsening clinical picture. Histology revealed vacuolar alteration with dyskeratotic keratinocytes and a superficial perivascular mixed infiltrate of lymphocytes and eosinophils. There was confluent parakeratosis containing neutrophils, and a diminished granular layer with pallor in the upper portion of the spinous layer. Immunofluorescence studies were negative. These findings were consistent with PLEVA. A clinical diagnosis of febrile ulceronecrotic Mucha-Habermann disease was made. Febrile ulceronecrotic Mucha-Habermann disease is a rare and severe variant of PLEVA characterised by high fever and papulonecrotic skin lesions. Twenty-five cases have been previously reported. We present the clinical and histological findings in this unusual clinical presentation. [source] Transepithelial elimination of cutaneous vulval granuloma inguinaleJOURNAL OF CUTANEOUS PATHOLOGY, Issue 10 2000Pratistadevi K. Ramdial Background: Transepithelial elimination (TEE), a distinct and well-known entity, is a process during which the skin eradicates undesirable or irritative dermal substances through intact epidermis or follicular epithelium by passive or active means. Although TEE is being described in an increasing number and range of pathological processes, to date, TEE of granuloma inguinale (GI) remains unrecorded in the English-language literature. The aims of this study were: 1) To appraise the light microscopic and ultrastructural morphological epidermal changes that are associated with TEE of cutaneous vulval GI; and 2) To determine the role of intra-epidermal leucocytes and histiocytes in the pathogenesis of TEE of vulval GI. Methods: This is a retrospective 9-year histopathological review of all cases diagnosed and coded as vulval granuloma inguinale in the Department of Anatomical Pathology, Nelson R. Mandela School of Medicine, University of Natal, Durban, South Africa. Ultrastructural evaluation was performed on selected cases using a Jeol transmission electron microscope. Results: Of 53 skin biopsies from 47 patients with vulval GI, 43 were suitable for the study. The age range of patients was 15,40 years (mean age=22 years). There were eleven papular, twelve nodular, seven verrucous and thirteen ulcerative lesions. Donovan bodies within macrophages, free-lying Donovan bodies and dense aggregates of neutrophils and plasma cells were seen in the dermis of all biopsies. There was consistent overlying pseudoepitheliomatous hyperplasia. The dermal inflammatory infiltrate hugged the dermo-epidermal junction and appeared entrapped between elongated and acanthotic epidermal rete ridges and pegs. Transepidermal neutrophil microabscesses, histiocytes containing Donovan bodies and neutrophilic and histiocytic fragmentation were present. A variable number of free-lying and intra-histiocytic Donovan bodies and neutrophils were present on the surface of the epidermis. On ultrastructural investigation epidermal spongiosis, intracellular oedema, free-lying, intra-neutrophilic and intra-histiocytic Donovan bodies, and intact and degenerating neutrophils and histiocytes were evident between keratinocytes. The degenerative histiocytes demonstrated marked vacuolation, mitochondrial swelling and bacilli within phagolysosomal vacuoles, bound by intact or disrupted limiting membranes. Conclusion: The inflammatory infiltrate at the epitheliomesenchymal interface, pseudoepitheliomatous hyperplasia, intra-epidermal accumulation and disintegration of neutrophils and histiocytes, and the associated release of lytic enzymes, play important contributory roles in TEE of GI. TEE of infectious agents is a poorly recognised mechanism of spread of infectious diseases and represents a public health hazard. In cutaneous vulval GI, TEE is highlighted as a hitherto unrecognised, potential method of spread of Calymmatobacterium granulomatis. [source] Chronic oral ulcer associated with CandidaMYCOSES, Issue 2 2010Haruhiko Terai Summary In the patients with HIV infection, fungal diseases may cause ulceration in the oral cavity; however, there have been few studies on oral ulcerative lesions associated with Candida in the patients without HIV infection. Our study included six patients with chronic oral ulcer of unknown origin; these patients were referred to our department after topical steroid therapy to the lesion was ineffective. Cases of traumatic ulcers and recurrent aphthous stomatitis were excluded. Blood, histopathological, culture and direct cytological examinations were performed. All the patients were treated with topical miconazole gel. Histopathological examination revealed no specific findings besides inflammatory cellular infiltration with positive haematoxylin,eosin staining in all cases. Candida spp. were isolated in four cases by culture test, and fungal pseudohyphae were revealed in four cases by direct examination. The anti-fungal treatment produced a satisfactory outcome with complete remission in five cases and remarkable response in one case. These results suggested that Candida should be considered as playing an important role in a certain oral ulcer. [source] Strongyloides Stercoralis Hyperinfection Transmitted by Liver Allograft in a Transplant RecipientAMERICAN JOURNAL OF TRANSPLANTATION, Issue 11 2009M. J. Rodriguez-Hernandez We describe a case of Strongyloides stercoralis hyperinfection in a liver allograft recipient 2.5 months after transplantation. The patient lives in Spain, which is not considered an endemic country for strongyloidiasis, and denied prior residence or travel to any known endemic area. The initial symptoms were fever and vomiting, and he subsequently developed a severe respiratory disease. An endoscopic biopsy of ulcerative lesions of the duodenum revealed massive mucosa infiltration by larvae and adult worms, which were also found in respiratory samples. The patient was successfully treated with combined therapy with albendazole and ivermectin. The strongyloides infection was transmitted by the liver allograft. The donor was from Ecuador and, retrospectively, his serum tested positive for S. stercoralis IgG antibodies. Additionally, the pancreas,left kidney allograft recipient from the same donor later developed an intestinal strongyloidiasis without hyperinfection syndrome. To our knowledge, this is the first confirmed case of S. stercoralis infection transmission from the same donor to two solid allograft recipients. [source] Erosive mucosal lichen planus and secondary epiphora responding to systemic cyclosporin A treatmentAUSTRALASIAN JOURNAL OF DERMATOLOGY, Issue 3 2009Aaron E Boyce ABSTRACT Erosive mucosal lichen planus (LP) is a well-established variant of LP characterized by the formation of ulcerative lesions predominantly involving the oral and genital mucosae. Less commonly, this condition may involve oesophageal and/or ocular mucosal surfaces, and case reports within the ophthalmology literature have recently confirmed the potential for this condition to affect the nasolacrimal ducts. We report the case of a woman with severe cicatrizing mucosal LP and ocular symptoms secondary to presumed nasolacrimal duct involvement. We also report the potential for this newly appreciated manifestation of LP to respond to systemic cyclosporin A. [source] Antibiotic responsive ulcerative dermatoses in German Shepherd Dogs with mucocutaneous pyodermaAUSTRALIAN VETERINARY JOURNAL, Issue 8 2004RJ BASSETT Mucocutaneous pyoderma is a disease of unknown aetiology affecting mucocutaneous skin and is responsive to antibacterial therapy. It is reported to affect the lips, nasal planum, nares, perioral skin and less commonly, the eyelids, vulva, prepuce and anus. Three cases of mucocutaneous pyoderma are presented. Two of the cases showed ulcerative lesions in the inguinal and axillary regions in addition to more typically reported lesions. Two of the dogs had concurrent atopic dermatitis and the third had clinical signs suggestive of hypersensitivity disease. The clinical and histopathological features, differentiation of mucocutaneous pyoderma from discoid lupus erythematosus, and long-term management of mucocutaneous pyoderma are discussed. [source] The local immune response in ulcerative lesions of Buruli diseaseCLINICAL & EXPERIMENTAL IMMUNOLOGY, Issue 3 2006A. E. Kiszewski Summary Buruli disease (BU) is a progressive necrotic and ulcerative disease of the skin and subcutaneous tissue caused by Mycobacterium ulcerans. BU is considered the third most common mycobacterial disease after tuberculosis and leprosy. Three clinical stages of the cutaneous lesions have been described in BU: pre-ulcerative, ulcerative and healed lesions. In this study we used immunohistochemistry and automated morphometry to determine the percentage of macrophages and of CD4/CD8 lymphocytes and their expression of interferon (IFN)-,, interleukin (IL)-10, tumour necrosis factor (TNF)-, and transforming growth factor (TGF)-,. Expression of these cytokines was correlated with the inflammatory response evaluated by histopathology. All the studied BU ulcerative cases showed extensive necrosis and chronic inflammation. The most important feature was the presence or absence of granulomas co-existing with a mixed pro-inflammatory/anti-inflammatory cytokine balance. When granulomas were present significantly higher expression of IFN-, was seen, whereas in ulcerative lesions without granulomas there was increased expression of IL-10 and significantly higher bacillary counts. These features correlated with the chronicity of the lesions; longer-lasting lesions showed granulomas. Thus, granulomas were absent from relatively early ulcerative lesions, which contained more bacilli and little IFN-,, suggesting that at this stage of the disease strong suppression of the protective cellular immune response facilitates proliferation of bacilli.
