Priapism--a rare presentation in chronic myeloid leukemia: case report and review of the literature.

Priapism is a complication rarely seen in leukemia. We report a 21-year-old man presented with persistent painful erection of penis for 19 hours at home. The patient had undergone immediate irrigation and decompression of priapism by urologist at emergency department. This approach resulted in a flaccid penis later. During hospitalization, peripheral blood smear and bone marrow aspiration was confirmatory of chronic myeloid leukemia. No impotency nor other sequela was noted after his discharge. This case illustrates the importance of all physicians in the diagnosis and management of patients with priapism.
