reactive extramedullary hematopoietic tumors

Reactive extramedullary hematopoietic tumors that usually occur in patients with severe chronic anemias.

Patients with extramedullary hematopoietic tumors are characterized by anemia, frequent hepatosplenomegaly and abnormal peripheral blood smears, and may be any age.

The tumors are usually multiple and usually located in the mediastinum or epidural space.

Differential diagnosis

Patients with extra-adrenal myelolipomas are usually older than 40 years, have normal blood studies, absent hepatosplenomegaly, and usually have chronic debilitating diseases or endocrinopathies.
