Abstract

OBJECTIVE: To describe and discuss primary malignant lymphoreticular proliferative tumors of the bladder. METHODS: A case of a 70-year-old woman with hematuria. dysuria, malaise and 5-kg weight loss is presented. RESULTS: Pelvic ultrasound examination showed an 8x7x8 cm solid and cystic mass adjacent to the bladder and uterus. Cytoscopic biopsy disclosed a low grade B cell non-Hodgkin lymphoma. Disappearance of the mass was achieved with 6 cycles of chemotherapy and radiotherapy. Four years thereafter the patient remains free of disease. CONCLUSIONS: Primary malignant lymphoma of the bladder is uncommon. The anatomopathological study is essential to differential diagnosis from other diseases. The response to chemotherapy and radiotherapy are excellent and permits bladder preservation.
