Priapism may be primary (idiopathic) or secondary to sickle cell anemia, trauma, leukemia, drugs, venous thromboembolic diseases, and other less common disorders. This study concerns 21 patients with priapism treated during a period of ten years. Nine patients (43 %) had sickle cell anemia. Of the 12 individuals (57 % ) classified as idiopathic, 3 (25 % ) had previously undergone surgical splenectomy for benign conditions. Considering the propensity for this unusual condition to develop in patients with hemoglobinopathy-induced hyposplenism, the possibility of a relationship between the asplenic state and priapism is considered.
