Materials and Methods
Thirty-seven cases of hypoplastic anemia were observed. All patients under study had a disorder characterized by: (1) severe pancytopenia, (2) hypoplasia of the bone marrow with at least 50% replacement of the normal marrow hematopoietic cells by fat, (3) the absence of splenomegaly, and (4) the absence of other
