1/11. Vasitis nodosa: immunohistochemical findings--case report.We report the immunohistochemical features of vasitis nodosa and discuss the differential diagnosis. The patient was a 42-year-old Japanese man with bilateral small indurations of the vas deferens at the site of a previous vasectomy. Microscopically, small-sized ducts proliferated within the muscular wall of the vas deferens, and focally in the surrounding connective tissue. Immunohistochemically, most proliferating glandular cells were strongly positive for cytokeratins 7, 19, and 34betaE12, and vimentin. Epithelial membrane antigen and Leu-M1 reacted against the luminal surface of the cells. Focally, glandular cells were also positive for CA125. Cytokeratin 20, carcinoembryonic antigen, and prostate-specific antigen were negative. We discuss the immunohistochemical differentiation of vasitis nodosa from prostatic adenocarcinoma, adenocarcinoma of the rete testis, and adenomatoid tumor.- - - - - - - - - - ranking = 1keywords = gland (Clic here for more details about this article) |
2/11. A seminal vesicle cyst complicated with a tumor like nodular mass of benign proliferating prostatic tissue: a case report with ultrastructural and immunohistochemical studies.We report a seminal vesicle cyst complicated with a tumor-like nodular mass of benign proliferating prostatic tissue. The patient was a 53-year-old Japanese man. A cyst of approximately 4.5 cm in diameter was discovered at the left seminal vesicle area. In the inner part of the cyst, a papillary nodular mass of 0.7 cm in diameter was seen. Under the clinical diagnosis of a seminal vesicle cyst with a tumorous mural nodule, the patient underwent resection of the seminal vesicle cyst to rule out the possibility that the nodular mass in the cyst was a neoplasm of an especially malignant nature. Microscopic examination of the excised specimen revealed a small dome-like nodular mass on the luminal surface of the cyst consisting of nodular proliferation of benign tubular gland tissue with various configurations. Conventional histologic, immunohistochemical, and ultrastructural analysis showed the proliferating cells in the nodular mass consisted of the benign prostate type. It is extremely important to differentiate between a benign proliferation and a malignant one, when the nodular mass is found in the seminal vesicle cyst.- - - - - - - - - - ranking = 0.5keywords = gland (Clic here for more details about this article) |
3/11. Unusual differential diagnosis of testis tumor: intrascrotal sarcoidosis.We report 2 cases of sarcoidosis with extrapulmonary manifestations in the testis, epididymis and spermatic cord. Each patient presented with an intrascrotal mass of unknown origin that suggested a testicular tumor. sarcoidosis was confirmed in case 1 by radical orchiectomy and further small sarcoid foci were detected in 1 of the lacrimal glands. In case 2 sarcoidosis was confirmed by biopsy and there were no further extrapulmonary indications. Both cases were stage II disease so no specific therapy was applied. The patients were without signs of progression at 2 and 10 years, respectively, after initial diagnosis.- - - - - - - - - - ranking = 0.5keywords = gland (Clic here for more details about this article) |
4/11. Prostatic glands and urothelial epithelium in a seminal vesicle cyst: report of a case and review of pathologic features and prostatic ectopy.We report a case of a seminal vesicle cyst containing prostatic glands and urothelial epithelium in a patient with no other urogenital anomalies. The detection of prostatic tissue, which is of endodermal origin, in a seminal vesicle cyst, a mesonephric duct derivative, is unusual. We review the pathologic features of seminal vesicle cysts and discuss the histogenesis of prostatic and urothelial tissue.- - - - - - - - - - ranking = 2.5keywords = gland (Clic here for more details about this article) |
5/11. Seminal vesicle abscesses: spectrum of computed tomographic findings.The computed tomographic (CT) findings in four cases of seminal vesicle abscess are presented. The predominant infectious organism in two cases was escherichia coli, one case was probably caused by mycobacterium tuberculosis, and another by atypical mycobacterium. The CT findings included unilateral (three cases) or bilateral involvement (one case), seminal vesicle enlargement with hypodense areas within the gland (three cases), adjacent perivesicle inflammation (three cases), and associated bladder wall thickening (three cases). Although the diagnosis of seminal vesicle abscess is often overlooked clinically, CT may help suggest the correct diagnosis early thereby helping to initiate therapy.- - - - - - - - - - ranking = 0.5keywords = gland (Clic here for more details about this article) |
6/11. aspermia owing to obstruction of distal ejaculatory duct and treatment by transurethral resection.A case of a young aspermic male patient with bilateral atresia of the terminal ejaculatory duct is reported. He was treated successfully by transurethral resection of the prostate gland in the area of the ejaculatory ducts.- - - - - - - - - - ranking = 0.5keywords = gland (Clic here for more details about this article) |
7/11. Cowper's gland calcification: a new radiographic finding.Cowper's gland calcification is reported in 3 elderly patients. The anatomy, pathology, and radiology of Cowper's glands are reviewed. Postulated etiologies of Cowper's gland calcification include ductal obstruction with stasis of secretions, infection with urea-splitting organisms, and sequelae of diabetes mellitus.- - - - - - - - - - ranking = 3.5keywords = gland (Clic here for more details about this article) |
8/11. Cowper's syringocele: a classification of dilatations of Cowper's gland duct based upon clinical characteristics of 8 boys.Lesions of Cowper's gland duct assume various appearances. A system to classify each of these appearances is offered to diagnose these lesions more precisely. The urethrographic and endoscopic characteristics of dilated Cowper's gland ducts noted in 8 boys are grouped as a simple classification. The dilated Cowper's duct is referred to as a syringocele (Greek syringo--tube plus cele--swelling). There are 4 groups of Cowper's syringoceles: 1) simple syringocele--a minimally dilated duct, 2) perforate syringocele--a bulbous duct that drains into the urethra via a patulous ostium and appears as a diverticulum, 3) imperforate syringocele--a bulbous duct that resembles a submucosal cyst and appears as a radiolucent mass, and 4) ruptured syringocele--the fragile membrane that remains in the urethra after a dilated duct ruptures. Marsupialization of the syringoceles cured urine infection and hematuria but voiding symptoms may persist.- - - - - - - - - - ranking = 3keywords = gland (Clic here for more details about this article) |
9/11. Acute scrotal swelling: a sign of neonatal adrenal haemorrhage.Two neonates presented with acute scrotal swelling suggestive of testicular torsion. Surgical exploration in one patient revealed an infected haematoma. Subsequent investigations including ultrasonography and urinary catecholamine determination disclosed adrenal haemorrhage as the cause of the scrotal haematoma. A second patient in whom a purplish discolouration of the right hemiscrotum was noted was also investigated with ultrasonography, which revealed a normal right testis and a right adrenal haematoma. Both cases of adrenal haemorrhage resolved spontaneously on conservative treatment. Adrenal haemorrhage should be considered as a possible cause of acute scrotal swelling in neonates. ultrasonography assessment should be performed in such cases to examine the intra-abdominal organs especially the adrenal glands.- - - - - - - - - - ranking = 0.5keywords = gland (Clic here for more details about this article) |
10/11. Scrotal elephantiasis associated with hidradenitis suppurativa.hidradenitis suppurativa is a chronic relapsing infection of the apocrine sweat glands. Its association with penoscrotal lymphedema is not well recognized. A case of massive scrotal elephantiasis associated with chronic hidradenitis of the perineum and scrotum is described. A wide resection of the scrotal mass and perineum was performed, with reconstruction of the perineum and penis carried out using local skin flaps and split-thickness skin grafts. This one-stage treatment yielded an excellent cosmetic and functional outcome.- - - - - - - - - - ranking = 0.5keywords = gland (Clic here for more details about this article) |
