Carcinoma of the renal pelvis and bladder associated with sarcoidosis: a case report.

A 75-year-old woman with transitional cell carcinoma of the renal pelvis was revealed to have sarcoid granulomas within the kidney as well as in the renal pedicle lymph nodes. Furthermore, noncaseating granulomas had been found in the pelvic lymph nodes in a histological study following previous total cystectomy for bladder cancer. The association of sarcoidosis with genitourinary malignancies is briefly discussed.
