We present a case of primary ureteral carcinoma composed of both transitional cell carcinoma and mucinous carcinoma. A 79-year-old woman visited her home doctor with the chief complaint of right lower abdominal pain. Abdominal computed tomographic scan (CT) disclosed a tumor measuring about 5 cm in diameter at the right lower quadrant of the abdomen. Percutaneous nephrostomy was performed for hydronephrosis and pyonephrosis. The urinary cytology revealed class V, transitional cell carcinoma. Re-abdominal CT showed further enlargement of tumor diameter, but the primary site of the tumor was not identified. Her general condition worsened, and she died 42 days after her initial complaint. Pathologic examinations upon autopsy revealed both mucinous carcinoma and transitional cell carcinoma in the right ureter. Pathogenesis and management of this rare condition are discussed.

A 62-year-old man consulted us for further examination of left giant hydronephrosis which was accidentally found by abdominal ultrasonography. The patient chose observation instead of left nephrectomy. One year later, he re-visited us with a complaint of sudden abdominal pain. Computed tomography (CT) revealed left giant hydronephrosis containing high-density fluid which was suspected of hemorrhage in the renal pelvis. Percutaneous nephrostomy yielded discharge of 7000 ml of hemorrhagic fluid and urine cytology revealed class V. Systemic examination by CT and magnetic resonance imaging (MRI) showed renal pelvic tumors in the left kidney as well as multiple metastatic lesions in the lung, liver and bone. Pathological examination of the left renal pelvic tumors obtained by biopsy showed high-grade urothelial carcinoma. Although systemic and intra-arterial chemotherapy showed partial response in the metastatic lesions, he died of cancer 1 year and 3 months after the first diagnosis.
