In September 2003, a 58-year-old woman complained of bladder irritation and urinary frequency. She was admitted to a nearby hospital, and an evaluation was performed. Urine cytology revealed a class V, and a tumor was detected in the lower left ureter with mild hydroneprhosis of the left kidney. We performed a left ureteronephrectomy with partial cystectomy in April 2004. The pathological diagnosis was clear cell carcinoma with small foci of conventional urothelial carcinoma of the left ureter (pT3pN0, G3 > G2, INFgamma). And now she lives well without recurrence in August 2005. This is the first case report of clear cell carcinoma of the ureter in Japan.

Renal-type clear cell carcinoma of the prostate is a rare and novel tumor that has only been identified in recent years. The present study describes a lesion in the prostate of a 64-year-old male with a two-year history of urinary frequency, urgency and difficulty, who was admitted to the San Ai Tang Hospital for benign prostatic hyperplasia, and subsequently underwent transurethral resection of the prostate. In total, 12 g of tissue was resected, which demonstrated morphological and immunohistochemical similarities to clear cell carcinoma of the kidney. Ultrasound inspection and computed tomography revealed prostate enlargement. Although no renal-enclosed mass was identified, metastatic lesions were revealed in the lungs, sternum and clavicles. In addition, right pleural thickening and a small amount of effusion in the pleural cavity were detected. Clear cell carcinoma was identified throughout the prostate, with surrounding regions of ordinary-type prostatic adenocarcinoma (Gleason score, 4+4). The urinary bladder exhibited no dysplasia or neoplasia. It was therefore concluded that the tumor represented a primary renal-type clear cell carcinoma that had arisen in the prostate. To the best of our knowledge, this type of extra-renal tumor has only been reported in three other previous studies.

We report two cases of clear cell adenocarcinoma arising in the urethral diverticulum. Case 1 occurred in a 79-year-old woman presenting with complaints of frequent micturition. Magnetic resonance imaging (MRI) revealed a localized urethral diverticular tumor. Transurethral resection of the tumor was performed, and the final histopathological diagnosis was clear cell adenocarcinoma. Anterior pelvic exenteration was performed. She had no recurrence 15 months after surgery. Case 2 occurred in a 79-year-old woman presenting with urinary incontinence. As in Case 1, MRI and histopathological findings of transurethral resection of the tumor revealed clear cell adenocarcinoma in the urethral diverticulum. Anterior pelvic exenteration and ileal conduit formation were performed. She had no recurrence 16 months after surgery. Clear cell adenocarcinoma in the urethral diverticulum is very rare. We review 17 cases of clear cell adenocarcinoma arising in the urethral diverticulum in Japan.
