The therapy of hypoplastic anemia may be said to be far from satisfactory. In addition to blood transfusions, numerous measures have been tried, including corticotropin (ACTH) and the corticosteroids,1 cobalt,2 testosterone,3 and splenectomy.4 In some cases, one or another of these measures proves to be beneficial, but in most, few if any lasting effects are noted.

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
