The more common causes of priapism are neurogenic stimuli (which include psychic, central nervous system, and local reflex stimulation), hematological disorders, (chronic myelogenous leukemia and certain hemoglobinopathies), and local mechanical or traumatic conditions.1 Priapism secondary to metastatic disease involving the penis is rare. The purpose of this report is to describe a patient with priapism as the initial manifestation of a renal malignancy.
