Inguinal Region (inguinal + region)
Selected AbstractsFine-needle aspiration of subcutaneous panniculitis-like T-cell lymphomaDIAGNOSTIC CYTOPATHOLOGY, Issue 5 2004Frances Manosca M.D. Abstract We report the fine-needle aspiration (FNA) cytology findings of Subcutaneous Panniculitis-like T-cell Lymphoma (SCPTCL) in a 66-year-old woman who presented with a four month history of asymptomatic subcutaneous nodules on her right chest wall and back. An excisional biopsy of the right chest nodules was performed, and the diagnosis of SCPTCL was rendered. On a follow-up visit, several skin lesions were noted throughout her body. A fine-needle aspiration (FNA) of the right inguinal region was performed. The FNA yielded cellular smears, composed mainly of sheets of epithelioid histiocytes and scattered multinucleated cells. However, no distinct granulomas were noted. The background of the cytological smears showed scattered atypical lymphoid cells, some of which displayed nuclear membrane irregularities. To the best of our knowledge, the cytological features on FNA material of SCPTCL have not been described. Diagn. Cytopathol. 2004;31:338,339. © 2004 Wiley-Liss, Inc. [source] Inguinal rupture with herniation of the urinary bladder through the scrotal fascia in a Shetland pony foalEQUINE VETERINARY EDUCATION, Issue 1 2010M. Cousty Summary Herniation of the urinary bladder in the inguinal region has not previously been described in the horse. A case of inguinal rupture with herniation of the bladder through the scrotal fascia in a 3-month-old Shetland pony, diagnosed by external palpation, urinary catheterisation and external ultrasonographic examination is reported. Surgical management of the case was by dissection of the scrotal fascia, partial cystectomy and unilateral castration. During the period of hospitalisation the only complication was a slight seroma, which resolved spontaneously. Follow-up after 6 months did not reveal any abnormality. [source] Necrotizing fasciitis: delay in diagnosis results in loss of limbINTERNATIONAL JOURNAL OF DERMATOLOGY, Issue 10 2006Rajat Varma MD A 58-year-old man presented to the Emergency Room with a 1-day history of severe pain in the left lower extremity preceded by several days of redness and swelling. He denied any history of trauma. He also denied any systemic symptoms including fever and chills. His past medical history was significant for diabetes, hypertension, deep vein thrombosis, and Evans' syndrome, an autoimmune hemolytic anemia and thrombocytopenia, for which he was taking oral prednisone. Physical examination revealed a warm, tender, weeping, edematous, discolored left lower extremity. From the medial aspect of the ankle up to the calf, there was an indurated, dusky, violaceous plaque with focal areas of ulceration (Fig. 1). Figure 1. Grossly edematous lower extremity with well-demarcated, dusky, violaceous plaque with focal ulceration Laboratory data revealed a white blood cell count of 6.7 × 103/mm3[normal range, (4.5,10.8) × 103/mm3], hemoglobin of 11.5 g/dL (13.5,17.5 g/dL), and platelets of 119 × 103/mm3[(140,440) × 103/mm3]. Serum electrolytes were within normal limits. An ultrasound was negative for a deep vein thrombosis. After the initial evaluation, the Emergency Room physician consulted the orthopedic and dermatology services. Orthopedics did not detect compartment syndrome and did not pursue surgical intervention. Dermatology recommended a biopsy and urgent vascular surgery consultation to rule out embolic or thrombotic phenomena. Despite these recommendations, the patient was diagnosed with "cellulitis" and admitted to the medicine ward for intravenous nafcillin. Over the next 36 h, the "cellulitis" had advanced proximally to his inguinal region. His mental status also declined, and he showed signs of septic shock, including hypotension, tachycardia, and tachypnea. Vascular surgery was immediately consulted, and the patient underwent emergency surgical debridement. The diagnosis of necrotizing fasciitis was then made. Tissue pathology revealed full-thickness necrosis through the epidermis with subepidermal splitting. Dermal edema was also present with a diffuse neutrophilic infiltrate (Fig. 2). This infiltrate extended through the fat into the subcutaneous tissue and fascia. Tissue cultures sent at the time of surgery grew Escherichia coli. Initial blood cultures also came back positive for E. coli. Anaerobic cultures remained negative. Figure 2. Necrotic epidermis with subepidermal splitting.

[source] Congenital absence of the testis in human fetuses and in cryptorchid patientsINTERNATIONAL JOURNAL OF UROLOGY, Issue 12 2004LUCIANO A FAVORITO Abstract, Background, The aim of the present study is to make a comparative study in human fetuses and in patients with cryptorchidism, analyzing the incidence of a number anomalies of the testes for both populations. Methods, We studied 326 testes from 163 human fetuses ranging in age from 10 to 35 weeks postconception (WPC) and 133 testes from 101 cryptorchid patients aged from 1 to 15 years old (mean, 6.4 years). The Fisher's exact test was used for comparison. Results, Among 326 fetal testes, 224 (68.7%) were abdominal, 45 (13.8%) were inguinal and 55 (16.8%) were scrotal. In one fetus at 23 WPC, both testes (0.6%) were absent. Of the 133 cryptorchid testes, 17 (12.78%) were abdominal, 92 (69.1%) were inguinal and 24 (18%) were high scrotal. Of the 17 abdominal testes, three (17.6%) were atrophic and two were vanished (11.7%). Of the 92 inguinal testes, one (1.08%) was vanished. Twenty-eight (21%) of the cryptorchid testes were impalpable and among these, 17 were located in the abdomen (60.7%) and 11 (38.2%) in the inguinal region (internal ring). Conclusions, Testicular agenesis is a very rare anomaly, both in fetuses and patients with cryptorchidism.

Schure Abstract Malignant pleural mesotheliomas are rare malignancies associated with asbestos exposure and these tumors are infamous for their poor prognosis. Mesotheliomas in other body areas are much rarer. They may occur in the abdominal cavity and also in the inguinal region. In the latter area they are commonly confused with much commoner benign conditions. We present three cases of mesotheliomas in the tunica vaginalis testis. J. Surg.

[source] Angiomyofibroblastoma-like tumor (lipomatous variant) of the inguinal region of a male patientPATHOLOGY INTERNATIONAL, Issue 9 2002Masayuki Shintaku A case of angiomyofibroblastoma-like tumor (lipomatous variant) that arose in the subcutis of the inguinal region of a 45-year-old man is presented. The maximum dimension of the tumor measured 39 mm and it was well circumscribed. Histopathological examination revealed a close admixture of plump spindle or stellate cells and mature adipocytes. These were arranged haphazardly or formed interconnecting thin cellular trabeculae on the myxoid or edematous background. The tumor was highly vascularized and contained a moderate amount of collagen fibers. Immunohistochemically, the tumor cells were positive for vimentin, CD34 and the estrogen receptor, but negative for ,-smooth muscle actin and desmin. The differential diagnosis between the lipomatous variant of angiomyofibroblastoma and cellular angiofibroma or spindle cell lipoma is discussed, and the pathogenetic hypotheses about the occurrence of mature adipocytes within benign fibroblastic or myofibroblastic neoplasms are mentioned briefly. It is important for surgical pathologists to be acquainted with the occasional presence of adipocytes in these neoplasms to avoid misinterpretation. [source] Therapy-resistant skin ulcers on hypoplastic leg associated with neurofibromatosis type 1THE JOURNAL OF DERMATOLOGY, Issue 2 2008Taku FUJIMURA ABSTRACT We describe a case of therapy-resistant skin ulcers in sporadic neurofibromatosis type 1. A 40-year-old woman had suffered from neurofibromata on her trunk and extremities since 30 years prior. She suffered from hypoplasia of her right leg from a young age and had a 1-year history of therapy-resistant skin ulcers on the leg and inguinal region. Magnetic resonance angiography disclosed a narrowed femoral artery at the level of the upper thigh with poor root in the inner side corresponding to the ulcerated lesions. The vascular changes were thought to be the cause of the skin ulcers. [source] Vaginal Ring and Round Ligament of the Uterus in the Female CatANATOMIA, HISTOLOGIA, EMBRYOLOGIA, Issue 4 2009A. Watson Summary The peritoneum was examined for the existence of a vaginal ring and the round ligament of the uterus was dissected through the inguinal region in eleven embalmed adult female cats. In all cats, there was no evidence of a peritoneal evagination into the inguinal canal. There was no vaginal ring and no vaginal process. The round ligament of the uterus passed through the inguinal canal and disintegrated in the fascia a short distance beyond the superficial inguinal ring. [source] Polyorchidism: a three-case report and review of the literatureANDROLOGIA, Issue 1 2010M. Savas Summary The presence of more than two testes confirmed by histology is called polyorchidism. Polyorchidism is an extremely rare congenital anomaly with a few more than 100 cases reported in the literature. The majority of reported cases are asymptomatic patients, others present with cryptorchidism, hydrocele, varicocele, epididymitis, infertility, testicular malignancy and testicular torsion. Over a 2-year period, we encountered three patients who were found to have polyorchidism; two men presented with cryptorchidism and one with chronic scrotal pain. Physical examination of the first and the third patient revealed normal testes in the scrotal sac, the other scrotal sac was empty and small solid mass (atrophic left testes) was palpated in the inguinal canal. Ultrasonographic examination of the scrotum and inguinal region confirmed the findings of the physical examination. Ultrasonographic examination of the second patient revealed supernumerary testes within the scrotum. Orchiectomy was made on the first and third patients' supernumerary testes and ipsilateral inguinal high ligation was applied for herniorrhaphy. A conservative approach was preferred for the second patient, maybe preserving a potentially functional supernumerary testis to improve the capacity for spermatogenesis. The risk of malignancy justifies the removal of an atrophic and ectopic testis in polyorchidism. However, it would appear safe to preserve a viable intrascrotal supernumerary testis found incidentally at surgery, provided that the patient is followed-up in the long term. [source] Fluorodeoxyglucose positron emission tomography studies in the diagnosis and staging of clinically advanced prostate cancerBJU INTERNATIONAL, Issue 1 2003J. Sung OBJECTIVE To determine the value of 18F-fluoro-2-deoxyglucose (FDG) positron-emission tomography (PET) studies in evaluating patients with advanced prostate cancer. PATIENTS AND METHODS FDG-PET scans were taken in 30 patients with advanced prostate cancer 1 h after an injection with 555 MBq of FDG. Patients were scanned from the base of the skull to the inguinal region (including the pelvis). They were also assessed by computed tomography (CT) of the abdomen and pelvis, and bone scintigraphy, to evaluate them for metastases. RESULTS Thirteen patients had locally extensive prostate cancer and 17 had metastatic disease. Twenty of the 30 patients were positive for radioisotope uptake in the prostate or extraprostatically. The patients with PET-detected prostate cancer were untreated (seven), treated hormonally while they had rising PSA levels (eight), or treated hormonally with a detectable but stable PSA (five). The remaining 10 patients were negative for FDG uptake in the prostate or any metastatic sites; these 10 patients were receiving hormone therapy, with undetectable PSA levels. CONCLUSION FDG-PET imaging is not a useful test in evaluating advanced prostate cancer in patients being treated and who have an undetectable PSA level. Staging of advanced prostate cancer may be enhanced by FDG-PET imaging in patients who are untreated, who have had an incomplete response to therapy, or who have a rising PSA level despite treatment. [source] Langerhans cell histiocytosis in an adult: good response of cutaneous lesions to acitretinCLINICAL & EXPERIMENTAL DERMATOLOGY, Issue 6 2010J. C. Cardoso Summary A 57-year-old man presented with a 2-year history of bilateral erosive lesions on the inguinal region, and erythematous, brown and crusted papules over the trunk. Histological examination of one lesion in conjunction with immunohistochemical study and electron microscopy led to the diagnosis of Langerhans' cell histiocytosis. After a thorough examination, the only associated findings were retroperitoneal fibrosis and hypergonadotrophic hypogonadism with a granulomatous testicular infiltrate. The patient was treated with oral acitretin for 1 year (with a topical corticosteroid for the inguinal lesions), resulting in clearing of the cutaneous lesions. He underwent placement of bilateral double-J ureteral catheters and was started on hormone replacement therapy. At follow-up 1 year after treatment with acitretin ceased, the patient remained free of cutaneous lesions and his overall condition, including the retroperitoneal fibrosis, had improved. This case had an uncommon combination of features, with a good response to acitretin. [source] Anatomy of the lateral femoral cutaneous nerve related to inguinal ligament, adjacent bony landmarks, and femoral arteryCLINICAL ANATOMY, Issue 8 2008Porames Doklamyai Abstract Lateral femoral cutaneous nerve (LFCN) generally emerges from the pelvis behind the inguinal ligament (IL) to the thigh. Because of its proximity to the anterior superior iliac spine (ASIS) and hip joint, the LFCN is prone to injuries during various procedures. Anatomy of this nerve is highly variable among studies. Moreover, measurement data regarding its branches including the differences between genders and sides are still lacking. This study was, therefore, done to clarify these issues. Eighty-five thighs from 43 cadavers of both genders were dissected at the inguinal region. Distances from each branch of the LFCN to palpable landmarks: the ASIS, pubic tubercle (PT) and femoral artery (FA) were measured along the IL. Up to four branches of the LFCN were found; however, the single trunk was the most common form (>65%). The common site of this pattern on the IL was within 2 cm medial to the ASIS but could be present at over 6 cm. The distances in case of bifurcation were mostly comparable to those of the single trunk. In contrast, the values varied considerably in the cases with three or more branches (three cases). Regarding side and gender, asymmetry in the branching pattern was found in one fourth of specimens. However, only some minor differences between genders or sides in the measurement data were seen. These findings suggest that asymmetry and multiple branches of the LFCN should be concerned. The measurement data are also useful for localizing the LFCN with higher accuracy. Clin.
