Chronic lymphocytic leukemia presenting as acute urinary retention due to leukemic infiltration of the prostate.

Acute retention of urine as the first clinical manifestation of an unsuspected, asymptomatic chronic lymphocytic leukemia (CLL) is found only in sporadic case reports. This report documents a case of CLL in a 65-year-old man presenting with acute urinary retention. The literature pertinent to this topic is briefly discussed.
