Primary Papillary Adenocarcinoma of the Ureteric Stump / 대한비뇨기과학회지

ABSTRACT

After nephrectomy for non-malignant disease, primary tumors of the ureteric stump are extremely rare and present a significant diagnostic problem, and only few cases have been reported in the literature. The very rare adenocarcinoma of the ureter is typically papillary and is associated with urinary tract infection and stones. In adenocarcinoma, because it is often difficult to determine whether the tumor is primary or secondary due to the generalized instability of the urothelium, and its histogenesis and biologic behavior remain uncertain partially due to the rarity of this neoplasm, a diagnostic differentiation pathologically from other tumors is required. We herein describe a case of 68 year old man who had a primary well-differentiated papillary mucigenic. adenocarcinoma of the ureteric stump after nephrectomy for renal stones.
