CML is a chronic myeloproliferative disorder associated with activating mutations in tyrosine kinases forming a BCR-ABL fusion gene, causing hyperproliferation of neoplastic myeloid progenitors [1,2]. The incidence of CML peaks in the fourth and fifth decades of life [3]. In the United States, nearly 4,500 cases are diagnosed annually [3]. The onset of the disease is insidious due to the nonspecific initial “B symptoms,” such as increased fatigability, weight loss and weakness. The natural history of CML is slow with a median survival of three years if untreated [3,4]. The current treatment is targeted therapies to the BCR-ABL tyrosine kinase using imatinib or nilotinib and hydroxyurea. Although B symptoms are common, priapism can be an initial presentation of CML in 1-5% of cases [5]. Priapism is a urological emergency defined by a sustained erection of four or more hours. Hyperviscous blood in leukemias, such as CML, prevents appropriate venous drainage of the corpora cavernosa, resulting in failure of detumescence [4]. This case reports highlights priapism as a presenting sign of CML and reviews the pathophysiology between the association.
