title: Polycythemia vera in a 12-year-old girl: a case report.
abstract: A case of a 12-year-old girl presenting with headache and splenomegaly and fulfilling the diagnostic criteria of polycythemia vera is reported. Her peripheral blood values were as follows: hemoglobin 18 g/dL, red blood cells 7,000,000/mm3, while blood cells 22,000/mm, and platelets 1,248,000/mm3. Phlebotomy was performed initially but was ineffective. Afterward 100 mg/kg per day aspirin and 30/mg/kg per day hydroxyurea were given. The patient has been asypmtomatic for 1 year and her recent hemoglobin level is 15.5 g/dL, platelet count 922,000/mm3, and white blood cell 12,800/mm3. Polycythemia vera is an extremely uncommon disease in childhood and for this reason its treatment is not well established.
