title: [Spontaneous rupture of the ureter as the primary symptom of malignant lymphoma].
abstract: 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.
