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 58-year-old man visited our hospital with a complaint of asymptomatic gross hematuria for three weeks. The urine cytology at another clinic had indicated Papanicolaou class V. A physical examination revealed soft abdominal distention in lower abdomen. Ultrasonography demonstrated an extremely dilated left pelvis, calyx and ureter in which a round mass was detected. Enhancement CT showed a mass 2 cm in diameter in the middle part of the dilated left ureter. These findings suggested the diagnosis of left ureteral cancer having developed in the megaureter. Neither VUR nor UVJ stenosis were identified by VCG and RP. MR-urography showed a severely dilated left pelvis and tortuous megaureter. On the diagnosis of left ureteral cancer left nephroureterectomy with cuff of bladder was performed. Gross findings showed a 2 cm sized papillary tumor in the extremely dilated ureter, and pathological findings showed grade 2, papillary transitional cell carcinoma and non-specific ureteritis in the dilated ureter. Postoperative course was non-eventful. Postoperative 3 months later multiple bladder tumors were detected all over the bladder, and so TUR-Bt and intravesical instillation therapy with pirarubisin was performed. However multiple bladder tumors had been relapsed and so finally radical cystectomy and right cutaneous ureterostomy were undergone postoperative 6 months later. He has been well 48 months postoperatively.

We report a rare case in which upper ureteral rupture was the primary symptom of malignant lymphoma. A 74-year-old female visited our hospital with left flank pain. Computed tomography showed urinoma around the left kidney and retrograde pyelography showed a diffuse filling defect in the left ureter and a rupture of the upper portion of that ureter. A urine cytology specimen from the left ureter was class V, suggesting undifferentiated carcinoma or malignant lymphoma. An open laparotomy revealed a nodule on the omentum and diffuse fibrosis around both ureters, and the histopathological diagnosis was diffuse large B-cell lymphoma. The patient' s ureteral stenosis disappeared after she received six cycles of R-CHOP (cyclophosphamide, doxorubicin, vincristine, prednisolone and rituximab) chemotherapy. We should be aware that malignant lymphoma can be the cause of a spontaneous ureteral rupture.
