Extra-nodal small cell lymphocytic lymphoma of prostate: an unusual cause of lower urinary tract symptoms.

Malignant lymphoma of the prostate is a rare occurrence. We describe a case of 60-year-old man presenting with acute urinary retention due to small cell lymphocytic secondary lymphoma of the prostate. We present the clinical manifestation of the disease emphasizing that all lower urinary tract symptom (LUTS) cases should be evaluated for the potential that metastatic cancers or lymphomas may present with such a diagnosis. We also present and tabulate a detailed review of at least 5 such similar reports (in which LUTS was the presenting symptom) published in the English literature to date.
