慢性骨髄性白血病に伴う持続勃起症

A case of chronic myeloid leukemia found by the priapism

症例は32歳男性。有痛性持続勃起症を主訴に，近医より紹介受診となった。症状出現から当院受診まで約12時間が経過していた。陰茎海綿体血液ガス分析にて著明なアシドーシスと低酸素所見を認め，虚血性持続勃起症と診断，瀉血，フェニレフリン投与にて勃起状態の改善を認め，その後再燃を認めなかった。同時に行った採血にて著明な白血球増加を認め，骨髄穿刺にて慢性骨髄性白血病と診断，ヒドロキシカルバミドとニロチニブにて治療開始となった。

A 32-year-old man consulted our hospital with the complaint of a continuous rigid and painful erection which began 12 hours before. We diagnosed ischemic type of priapism by analysis of penile cavernosal blood aspiration. We immediately performed therapeutic aspiration, irrigation and intracavernous injection of sympathomimetics. After therapy, erection and symptoms disappeared. Leukocytes count was 361,000/ul and chronic myelogenous leukemia（CML）was suspected. CML was treated by hydroxycarbamide and nilotinib. No evidence of reccurence was observed.
