title: [Primary malignant lymphoma of the ureter: a case report].
abstract: A 58-year-old man who had right hydronephrosis pointed out by medical checkup visited our hospital. Computed tomography and retrograde pyelography revealed a soft tissue mass in the middle portion of the right ureter. Urine cytology specimen from the right ureter suggested transitional cell carcinoma. Under the diagnosis of right ureteral cancer, we performed right total nephro-ureterectomy, partial cystectomy. The histopathological examination showed non-Hodgkin lymphoma (large B-cell type) of the ureter. Our diagnosis was Clinical Stage IE of the Ann Arbor Classification. The patient received only the first course of systemic chemotherapy (THP-cop), because he suffered severe thrombocytopenia in the course of the chemotherapy. No recurrence was found for 15 months after operation, and at present he is disease-free.
