IN ACUTE leukemia, with or without peripheral leucocytosis, sternal-marrow aspiration by the Arinkin technique characteristically reveals marked hyperplasia with a predominance of immature "blast" cells.1 Because of this usually typical picture, marrow study is of particular importance in differentiating cases of acute leukemia without peripheral leucocytosis from cases of aplastic anemia and granulocytopenia.
We are reporting two cases of acute leukemia with peripheral leucopenia which are atypical in that the patients presented hypocellular marrows rather than the usual hypercellularity. One patient had persistent leucopenia and a hypoplastic marrow throughout his course. The other, during a relapse following cortisone therapy, had hypercellular marrow with associated leucocytosis.
