In this article, we review prostatic lymphomas and discuss the differential diagnosis of high-grade malignant neoplasms of the prostate. We illustrate this with a case of a 46-year-old man seen with lower urinary tract obstruction who had diffuse involvement by a high-grade malignancy on prostate biopsy. Morphologic evaluation and immunohistochemistry were consistent with diffuse large B-cell lymphoma of the prostate. Workup with positron emission tomography-computed tomography demonstrated intensely hypermetabolic lymph nodes in the mediastinum, as well as widespread osseous involvement and involvement of the pancreatic tail, prostate, and urinary bladder, suggesting secondary prostatic involvement by a nodal lymphoma. Lymphomas of the prostate are uncommon in surgical pathology practice and usually represent secondary involvement from leukemia/lymphoma at a more typical site. Chronic lymphocytic leukemia/small lymphocytic lymphoma is the most common subtype.

Primary prostate lymphoma (PPL) is rare. This article reports a case of PPL by retrospective analysis of the clinical data and review of the literature, in an attempt to explore the diagnosis, treatment, and prognosis of this rare disease. The present case involves a male patient who came to our hospital for medical consultation of dysuria. Serum prostate-specific antigen (PSA) was not remarkable. Pelvic computed tomography (CT) scan suggested obvious enlargement of the prostate and a tumor in the prostate, but the tumor was not significantly enhanced on contrast-enhanced CT scan. Ultrasound suggested obvious enlargement of the prostate with multiple local low-density echoes and rich blood flow signals inside. Histopathology of prostate biopsy suggested prostate diffuse large B-cell lymphoma (DLBCL). The patient refused chemotherapy but agreed to receive radiotherapy. After radiotherapy, the tumor became smaller and the International Prostate Symptom Score (IPSS) score was reduced. Our experience, together with literature review, suggests that prostate puncture biopsy is an important method for the diagnosis of PPL, and imaging examination can assist the diagnosis. Radiotherapy is able to reduce the tumor volume and relieve the symptoms of urinary tract obstruction, and chemotherapy can help achieve a better therapeutic outcome.
