title: A rare case of renal hemangioma presenting as polycythemia.
abstract: Instances of renal cell carcinoma and erythropoietin-producing renal cysts presenting as polycythemia are well documented. To our knowledge, no case of hemangioma presenting as polycythemia has been reported. We present a case of a 39-year-old man with a 5-year history of polycythemia requiring phlebotomy every 3 months. Computed tomography revealed a 6 to 7-cm right upper pole renal mass. The patient underwent right radical nephrectomy, and pathologic examination revealed the mass to be a capillary hemangioma. The patient has not required phlebotomy for 1 year since the removal of the hemangioma.
