We report a case of primary mucinous adenocarcinoma arising in the bulbomembranous urethra. The patient underwent radical cystectomy and total penectomy, followed by systemic chemotherapy. Metastases in lungs, skin, and lymph nodes (inguinal, iliac, para-aortic, and tracheobronchial) were found within 2 months after operation. We reviewed 37 cases of primary adenocarcinomas of the male urethra.

Clear cell carcinoma (CCL) arising in the lower urinary tract is unusual and we report the cytohistologic findings of three cases retrieved from our files. All patients presented with bleeding, and the tumors were localized in either the urethra or bladder base. Filter and cytocentrifuge preparations of the urine were studied and all cases displayed numerous scattered aggregates or single tumor cells in an inflammatory background. The enlarged cells had abundant clear, wispy cytoplasm with discrete vacuolation. Hobnail and signet ring cells were apparent. The nuclei had granular to vesicular chromatin with prominent often multiple nucleoli. The tumors were histologically distinctive and typically had a tubulocystic configuration with varying proportions of papillary and diffuse patterns. One patient has died of metastatic cancer and two are presently free of tumor. The cytohistologic features of this cancer are characteristic and from our review we conclude that this lesion can be diagnosed by cytologic means.

Clear cell adenocarcinoma of the female urethra is a rare disease. We herein report the 23rd case of clear cell adenocarcinoma of the female urethra in Japan. A 75-year-old female visited our hospital because of pollakisuria. Pelvic CT revealed a 2.2 cm tumor surrounding the entire circumference of the urethra with pelvic lymph node metastases. Chest CT revealed mediastinal lymph node metastases. She underwent anterior pelvic exenteration and ileal conduit urinary diversion. Pathological diagnosis of the tumor was clear cell adenocarcinoma. She has been alive 11 months after surgery in spite of enlarged mediastinal lymph node metastases.

Penile metastases from prostate cancer are rare and are usually a manifestation of wide-spread cancer dissemination. Isolated urethral metastases form a small fraction of these cases, have a longer survival rate and may represent spread by implantation following instrumentation. We report a case of prostatic carcinoma presenting with an isolated metastasis to the penile urethra after catheterisation and transurethral prostatectomy. The primary tumor had a prominent intraductal component whose architectural features were mimicked in the metastasis. The possible mechanisms of spread and the diverse appearances of cancer associated with an intraductal component are discussed.

Like a pulmonary counterpart, extrapulmonary small cell carcinoma (SCC) is an aggressive tumor with a high rate of metastasis. Forty-nine fine-needle aspiration biopsies (FNABs) (36 patients) of various primary sites other than the lung diagnosed as metastatic SCC (including Merkel cell carcinoma) were reviewed. FNABs were derived from lymph nodes (20), liver (7), bone (2), breast (1), pancreas (1), and skin/soft tissue (18). Primary tumor sites included the prostate (14), skin (11; Merkel cell carcinoma), cervix (5), urinary bladder (3), urethra (1), ovary (1), and parotid (1). Aspirates revealed predominantly dispersed single tumor cells with occasional clustering. Tumor cells were small with scant cytoplasm, fine powdery chromatin, and inconspicuous nucleoli. Nuclear molding, mitotic figures, and apoptotic bodies were frequently observed. In four cases, findings from the FNABs were used to render the initial diagnosis of SCC. FNAB is useful for determining whether metastases contain a SCC component, a finding that may alter clinical management. Cytologically, SCC from different primary sites cannot be differentiated, and its distinction requires clinical and radiographic correlation.

Between May 1984 and November 1998 a total of 27 consecutive patients with bladder tumor (26 transitional cell carcinomas and 1 leiomyosarcoma) underwent supra-ampullar cystectomy and ileal orthotopic neobladder (2 Camey I and 25 Camey II). Mean patients age was 51.1 years (range 23-65). Pre-operatively 22 patients had superficial bladder carcinoma. An involvement of prostatic urethra was excluded by biopsy. The bladder, part of the prostate with prostatic urethra and regional lymph nodes were removed while was deferens, deferential ampullae, seminal vesicles, ejaculatory ducts and peripheral portion of the prostate were saved. Mean follow-up was 56.5 months (range 4-178). One patient was lost to follow-up at 60 months. Of the 27 patients 6 died of bladder cancer (1 with local relapse, 1 with local and distant recurrence and 5 with metastases) and the remaining 21 had neither local nor distant relapse. Four patients died of other causes. Potency was preserved in 25 patients (92.5%) who reported satisfactory sexual intercourse. Sixteen patients (59.2%) also maintained ejaculation allowing procreation in two of them. Supra-ampullar cystectomy provides good results in term of quality of life allowing to preserve sexual function in nearly all the cases without compromise the control of the neoplastic disease. The indication must be restricted to bladder cancer without risk of local recurrence and concomitant prostatic carcinoma.

Primary malignant melanomas of the urethra are extremely rare. Clinically they are usually mistaken for other malignant diseases or even benign lesions. The case of a 66-year-old woman is reported, who presented with local bleeding of the urethra. Macroscopically a polypoid tumor was seen on the meatus externus of the urethra. A biopsy was taken and the histology report revealed a malignant melanoma. There were no signs of metastases and therefore the treatment consisted of a wide local excision only. A review of literature regarding therapy and prognosis is presented.

The authors report one case of indifferentiated sarcoma of the prostate revealed by phlebitis of the right inferior limb and lung's metastases in a man 41 years old. The tumor progress rapidly and infiltrate the bladder and the posterior urethra. The patient died five months later. They review the literature and study the clinical histological, therapeutic and evolutive aspects of this unusual tumor.

We report here 3 cases of papillary adenocarcinoma of the prostate. In all 3 cases, the tumors were discernible on cystourethroscopy and transurethral biopsy established the diagnosis, whereas no significant finding was found on digital rectal examination. Although androgen deprivation therapy was administered in all cases, different surgical procedures were employed according to the stage in each case. In case 1, since the papillary tumor was confined within the prostatic urethra, complete resection was accomplished by transurethral resection (TUR). In case 2, since pelvic lymph nodes metastases were found, local radiation therapy was added. In case 3, since the patient had vesical invasion of tumor total cysto-prostatectomy was performed. Papillary adenocarcinoma of the prostate originates from the prostatic duct, resulting in existence at the "central portion" of the prostate gland. Cystourethroscopy and transurethral biopsy is helpful for diagnosis of this disease, whereas rectal digital examination is useless. As a surgical procedure for the primary site, TUR may be efficient for tumors confined within the prostatic urethra, although more extensive surgery may be necessary for those with a more invasive profile.

We present a 40-year-old man with malignant priapism secondary to urethral squamous cell carcinoma. Magnetic resonance imaging revealed the tumor originating from the bulbous urethra, extending into the penile urethra and corpora spongiosa and cavernosa. A penile biopsy confirmed poorly differentiated squamous cell carcinoma of the urethra. Despite administration of systemic chemotherapy, the prognosis of the patient has worsened due to the extensive metastatic disease.
