Papillary adenocarcinoma of ureter.

A well-differentiated papillary adenocarcinoma developed in a ureteral stump thirty-six years after nephrectomy and was associated with a combined transitional-epidermoid carcinoma in the urinary bladder. Carcinoma in a ureteral stump is not uncommon and should be suspected in patients with a ureteral stump and hematuria. The very rare adenocarcinoma of the ureter is typically papillary and is associated with urinary tract infection and stones. At present successful treatment requires the early identification and extirpation of the ureteral tumor and consideration of associated cancer elsewhere in the urinary tract.
