1/9. leiomyoma of the male urethra: a case report and review of the literature.We describe the case of a 48-year-old quadriplegic black man with history of C4-C5 cervical spine and cord injury secondary to a fall, who presented to the University of Cincinnati Medical Center urology Service with obstructive symptoms at urination. A bulbous urethral stricture was diagnosed and subsequently resected with primary urethral reanastomosis. On pathologic examination, the surgical specimen contained an epithelioid leiomyoma at the site of the urethral stricture. Although leiomyomas of the female urethra are relatively common, we identified only 2 previously reported cases of leiomyomas of the male urethra in the English-language medical literature. To the best of our knowledge, we describe the third case of leiomyoma of the male urethra, the first of the epithelioid type.- - - - - - - - - - ranking = 1keywords = black (Clic here for more details about this article) |
2/9. Periurethral colonic-type polyp simulating urethral caruncle. A case report.A 50-year-old, black woman presented with a 1-cm, polypoid lesion on the posterior edge of the urethral meatus that had the gross appearance of a urethral caruncle. The histologic features, however, revealed a superficially ulcerated lesion composed of colonic-type mucosal glands with focal regenerative atypia in response to inflammation. A similar histologic pattern is also found in so-called solitary rectal ulcer syndrome and inflammatory cloacogenic polyps arising in the anorectal area. Based upon an English-language literature review, this case appears to be the second reported one of an intestinal-type polyp in this location. The patient had no further problems after excisional biopsy.- - - - - - - - - - ranking = 1keywords = black (Clic here for more details about this article) |
3/9. Primary malignant melanoma of the male urethra.Primary malignant melanoma of the male urethra is a rare disease, with only 24 cases previously reported in the literature, including 1 black patient. We describe 2 additional patients with primary malignant melanoma of the urethra, one of whom was a black man. The literature is reviewed briefly and treatment recommendations are discussed.- - - - - - - - - - ranking = 2keywords = black (Clic here for more details about this article) |
4/9. glycogen-rich clear cell carcinoma of the urethra: an ultrastructural study.A 49-year-old black woman developed a urethral glycogen-rich clear cell carcinoma. She was treated with anterior pelvic exenteration. The resected lymph nodes, vagina, uterine cervix, endometrium, ovaries, and urinary bladder were free of neoplasm. Histologically the neoplasm consisted of clear cells growing in sheets and occasional papillary structures. In some areas, hobnail cells were present. Ultrastructurally, the cells had apical caps, short microvilli, and complex cell bases, and contained abundant glycogen. These features were identified in one, but not the other of two previously reported cases. Because glycogen-rich clear cell carcinomas of the lower urinary tract do not resemble ultrastructurally mesonephric remnants or carcinomas known to arise from them, these glycogen-rich clear cell carcinomas should not be called "mesonephromas" as has been the practice.- - - - - - - - - - ranking = 1keywords = black (Clic here for more details about this article) |
5/9. Primary malignant melanoma of the urethra in a black man: a case report.We report a unique occurrence of primary urethral melanoma in a black man. The biological relationships to melanocyte/melanin site densities or to precursor mucosal lesions are discussed as possible etiological factors in the occurrence of this rare neoplasm.- - - - - - - - - - ranking = 5keywords = black (Clic here for more details about this article) |
6/9. Primary transitional cell carcinoma of the female urethra with features of clear cell adenocarcinoma.Primary malignant urethral neoplasms are unusual in women. Those of mixed histologic type are so rare as to define adequate documentation. We report the case of an elderly black woman with an urethral carcinoma which had features of a transitional cell carcinoma as well as clear cell adenocarcinoma. The histologic and ultrastructural features are presented and the histogenesis is discussed. Although the patient had both high grade and high stage disease and failed initially after external beam radiation therapy, she is alive and well, without evidence of recurrent disease, 19 months after anterior exenteration.- - - - - - - - - - ranking = 1keywords = black (Clic here for more details about this article) |
7/9. carcinoma in situ in urethral diverticulum: pitfalls of marsupialization alone.carcinoma in situ was found in a urethral diverticulum in a fifty-one-year-old black woman. The discovery of this lesion lends support to the fact that biopsy of the urethral diverticulum should be performed even if a Spence-Duckett procedure is carrier out.- - - - - - - - - - ranking = 1keywords = black (Clic here for more details about this article) |
8/9. lymphoma of urethra in patient with acquired immune deficiency syndrome.Primary involvement of the urethra by lymphoma is rare. We report the first case of a primary urethral B-cell lymphoma as the initial manifestation of the acquired immune deficiency syndrome (AIDS). A fifty-seven-year-old black man was evaluated for obstructive voiding symptoms and bloody urethral discharge. Workup revealed a urethral mass which, on pathologic examination, was a large B-cell lymphoma.- - - - - - - - - - ranking = 1keywords = black (Clic here for more details about this article) |
9/9. Primary malignant melanoma of the female urethra: a case report.A case of primary malignant melanoma of the female urethra is presented. A 65-year-old Japanese woman was referred with dysuria and urethral bleeding. A hemorrhagic blue-black tumor, 3 cm in diameter, was diagnosed as a malignant melanoma by urinary cytology and biopsy. In spite of radical surgery followed by adjuvant immunochemotherapy with beta interferon, dacarbazine, nimustine and vincristine (IFN beta-DAV), the patient died of the disease one year after surgery because of lung metastasis which developed six months after diagnosis. The regional lymph nodes were not involved. In the present paper, we have briefly discussed the diagnostic value of cytological examination for this condition, as well as biopsy, with regard to the risk of hematogeneous tumor spread.- - - - - - - - - - ranking = 1keywords = black (Clic here for more details about this article) |
