A 59-year-old woman with von Hippel-Lindau disease developed erythrocytosis and a recurrent intracranial hemangioblastoma. Radioimmunoassay showed an elevated level of erythropoietin in her serum. Cyst fluid from the tumor also contained erythropoietin,concentrated a thousandfold relative to the serum level.Production of erythropoietin by hemangioblastomas may explain the erythrocytosis present in some patients with von Hippel-Lindau disease. |
