Prostatic hypertrophy and prostatic infiltration in small lymphocytic lymphoma.

Extranodal involvement in non-Hodgkin's lymphoma (NHL) is not really that rare, but prostatic infiltration is uncommon and rarely detected clinically. Prostatic involvement by lymphoma can cause signs and symptoms of prostatic obstruction. Here we report a patient with prostatic infiltration due to NHL diagnosed 7 years earlier. The literature is also reviewed.
