Serum erythropoietin levels in von Hippel-Lindau syndrome.

Von Hippel-Lindau syndrome (HLS) is an autosomal-dominant inherited cancer-prone disorder associated with hemangioblastomas (Hbl) of the CNS, angiomatosis retinae (AR), renal cysts, renal cancer, pancreatic cysts, pancreatic cancer, and pheochromocytoma [10]. The main cause of death in this disease are Hbl of the CNS, followed by renal cancer and pheochromocytoma. AR can lead to unilateral or even bilateral loss of vision [11]. Manifestations of the syndrome usually develop in young adults [8].
