title: Polycythemia: a review article and case report of erythrocytosis secondary to Wilms' tumor.
abstract: We describe a child with Wilms' tumor whose only finding at presentation was polycythemia. A review of the mechanism of erythropoiesis regulation as well as the differential diagnosis, work-up, and management of polycythemia in children is presented. Our report emphasizes the need for a thorough evaluation of children who present with polycythemia.
