ABSTRACT

Primary urinary bladder lymphomas are rare, the vast majority of these are B type lymphocytes. This paper reports the case of a 31-year-old male patient who presented a history of gross haematuria. Cystoscopy revealed a large fixed mass located at the trigone. A resection of the mass was performed. Histology showed infiltration of malignant lymphoid cell with plasmacytoid features. The cells showed immunoreactivity to CD45 and CD20 and were negative to CD3, CD5, CD10, CD23. The tumor was classified as extranodal marginal zone lymphoma of mucosa-associated lymphoid tissue type. A thorax, abdomen and pelvis CT scan showed no evidence of systemic disease and a bone marrow biopsy was normal. Four years after receiving radiotherapy treatment, the patient has been well without evidence of recurrent disease. A new CT scan and cystoscoy were performed with negative results. Due to radiosensitivity of lymphomas, treatment may be applied with low doses of radiation with highly reduced morbidity results.
