1/204. Epidermoid carcinoma of the male urethra. Case report.A case of voiding difficulties was investigated. Other than usual prostatic obstruction or urethral stricture, a small mass at the anterior region of the bulbous urethra was present. Detailed investigation by urethroscopy, biopsy, CT imaging and ultrasonography revealed epidermoid carcinoma of the urethra.- - - - - - - - - - ranking = 1keywords = carcinoma (Clic here for more details about this article) |
2/204. recurrence of sigmoid colon carcinoma in the residual urethra after cystectomy.INTRODUCTION: We report a case of recurrence of sigmoid colon cancer in the residual urethra after cysto-prostato-sigmoidectomy. methods/RESULTS: The patient successfully underwent urethrectomy and is currently tumor-free. To our knowledge, this is the first case of recurrence of a non-urothelial malignant tumor in the residual urethra.- - - - - - - - - - ranking = 0.8keywords = carcinoma (Clic here for more details about this article) |
3/204. Urethral carcinoma recurrence in ileal orthotopic neobladder: urethrectomy and conversion in a continent pouch with abdominal stoma.A patient who had previously undergone ileal neobladder with Studer technique presented an urethral recurrence of a transitional cell carcinoma. Further surgical treatment consisted of urethrectomy and creation of an intussuscepted ileal loop which was anastomosed to the pouch and provided a continence mechanism allowing self-catheterization.- - - - - - - - - - ranking = 1keywords = carcinoma (Clic here for more details about this article) |
4/204. A case of urethral recurrence found 15 years after radical cystectomy.PURPOSE: A case of a urethral recurrence found 15 years after radical cystectomy is reported. methods/RESULTS: A 78-year-old man, who had undergone radical cystectomy at age 63, presented with urethral bleeding and positive cytology in urethral washing. The urethra was surgically resected. Pathologic examination revealed transitional cell carcinoma located in the distal and mid portion of the penile urethra. CONCLUSION: Evidence suggested that urethral recurrence resulted from the implantation from the primary bladder tumor; in addition, the urethral neoplasm had scarcely grown in the penile urethra for 15 years.- - - - - - - - - - ranking = 0.2keywords = carcinoma (Clic here for more details about this article) |
5/204. Transrectal ultrasound appearance of squamous cell carcinoma involving the prostate.PURPOSE: This report describes the transrectal ultrasound appearance of squamous cell carcinoma of the prostate. case reports: One case of squamous cell carcinoma involving the prostate by extension from a primary urethral carcinoma and a second case of radiation-induced primary prostatic squamous cell carcinoma are presented and the ultrasound findings discussed. CONCLUSIONS: In these 2 cases, squamous cell carcinomas involving the prostate exhibited similar transrectal ultrasound appearances. Both lesions demonstrated an irregular, anterior, relatively hyperechoic appearance. copyright copyright 1999 S.

6/204. Nephrogenic adenoma mimicking carcinoma: a potential pitfall in cytodiagnosis.Nephrogenic adenoma of the urinary bladder and urethra is an uncommon benign lesion of the urinary epithelium that can cytologically and histologically mimic malignancy. We report on the cytologic findings of a case of nephrogenic adenoma of the urethra that mimicked malignancy in an 84-yr-old woman. The differential diagnosis of this problematic lesion is discussed, and the literature describing the cytologic features is reviewed.- - - - - - - - - - ranking = 0.8keywords = carcinoma (Clic here for more details about this article) |
7/204. collagen polyp of the urinary tract: a report of two cases.Injection of collagen into the urethral or bladder wall has gained popularity as an effective way to control urinary stress incontinence. The same technique has recently been used to improve function of urinary pouches surgically created from intestinal segments. We report the first two cases of a polypoid lesion in these structures, both of which were composed of injected collagen. The first lesion occurred in the ileal urinary pouch of a 41-year-old paraplegic man who had cystoprostatectomy for severe spasm and repeated infection of the bladder. The pouch, removed for repeated infection, showed a 2.5-cm submucosal polyp. The second lesion was in the urethra of a 71-year-old man who underwent radical retropubic prostatectomy for prostatic carcinoma, followed by artificial urethral sphincter placement. Follow-up cystoscopy revealed a proximal urethral polyp that was biopsied. In both cases, collagen was injected into these structures for controlling urinary incontinence. Histologically, the polyps were caused by submucosal accumulation of injected collagen with pathognomonic features (i.e., eosinophilic, homogeneous, and poorly cellular material that was faintly positive by the periodic acid-Schiff and strongly positive by the trichome stain). These two cases expand the list of differential diagnoses for a polypoid lesion in the intestinal and urinary tracts and illustrate the morphology of injected collagen. A familiarity with these changes is diagnostically helpful because an increasing number of specimens removed for therapeutic failure of injected collagen are expected.- - - - - - - - - - ranking = 0.2keywords = carcinoma (Clic here for more details about this article) |
8/204. Carcinoma in diverticulum of female urethra.A case of female urethral diverticulum is reported by the authors. It is a rare disease and about 31 cases have previously been described. An analysis is made in relation to the diverticulum of the urethra and to female urethral carcinoma. Emphasis is given on the semiology and the recently acquired diagnostic procedures, as these have led to an increased number of recognized cases. In the case presented, an extended resection and a definitive urinary derivation was performed, together with chemo- and radiotherapy. A follow-up of 2.5 years showed no signs of recurrence or metastases.- - - - - - - - - - ranking = 0.2keywords = carcinoma (Clic here for more details about this article) |

10/204. Periurethral vaginal adenocarcinoma of the intestinal type: report of two cases and review of the literature.INTRODUCTION: Vaginal adenocarcinomas in the absence of diethylstilbestrol (DES) exposure are rare neoplasms. Only a few cases with enteric type histology have been reported. Also rare are urethral adenocarcinomas in women. case reports: Two cases of vaginal adenocarcinoma of the intestinal type in the absence of DES exposure are presented. Both cases arose in the periurethral area, raising the issue of urethral as well as vaginal origin. DISCUSSION: The possible histogenesis of these neoplasms is considered.- - - - - - - - - - ranking = 3.3527531169769keywords = adenocarcinoma, carcinoma (Clic here for more details about this article) |
