[Priapism as first clinical manifestation of chronic myeloid leucosis].

Blood disorders, in particular chronic myeloid leukemia (CML), are among the rare etiological factors of priapism. A clinical observation of ischemic priapism lasting 18 hours, which developed in patients with previously not diagnosed CML, is presented in the article. The CML was subsequently diagnosed based on the results of blood analyses and bone marrow aspiration. Treatment strategy consisted of immediate aspiration of blood from the cavernous bodies (19G) followed by the intracavernous injection of phenylephrine solution. After resolving priapism, CML therapy was carried out, which allowed to avoid a recurrence of priapism.
