Hematolymphoid tumor of prostate: Diffuse large B cell lymphoma case report

Prostate lymphomas are very rare, with few reported cases in the literature. However, differential diagnoses should be considered. We report a hematolymphoid tumor of the prostate in a 67-year-old man who was admitted to the hospital with hematuria and obstructive urinary symptoms. The patient underwent a cystoscopy procedure to obtain a biopsy from the prostate with bipolar resection. Histologically, sheets of lymphoid tumor cells resembling non-Hodgkin lymphoma, infiltrated into the prostatic tissue, were identified. The diagnosis of diffuse large B-cell lymphoma was confirmed by immunohistochemistry. The clinicopathologic characteristics of prostatic lymphomas are discussed in the light review literature.
