Extramedullary hematopoiesis in a child with hereditary spherocytosis: an uncommon cause of an adrenal mass.

摘要

We report a case of extramedullary hematopoiesis presenting as an adrenal mass in a young male with hereditary spherocytosis. The unilateral adrenal mass was discovered during an abdominal ultrasound performed for jaundice. CT and MR imaging were subsequently performed, followed by an excisional biopsy at the time of splenectomy and cholecystectomy. Although extramedullary hematopoiesis is a rare cause of an adrenal mass, the diagnosis must be considered in any patient with a history of a congenital hemolytic disorder such as hereditary spherocytosis. In this regard, the morbidity of an unnecessary procedure may be avoided.
