[Priapism complicated by chronic myelogenous leukemia (CML); a case report].

A-29-year-old man visited our hospital with the complaint of a continuous rigid and painful erection which began two days before. We diagnosed ischemic type of priapism by aspiration of penile cavernosal blood analysis; an acidotic and hypoxic blood. The leukocyte count was 263,000/p, and chronic myelogenous leukomia (CML) was suspected. After the failure of conservative treatment, glans-cavernosal shunt (Winter procedure) was performed. The postoperative course was uneventful and the intercourse was possible at five months after the operation. CML was treated by administration of imatinib mesylate and no evidence of recurrence was observed.
