title: Hairy cell leukemia with acquired dyserythropoiesis.
abstract: Dyserythropoiesis, a qualitative abnormality of erythrocyte production, is described in a patient with hairy cell leukemia (leukemic reticuloendotheliosis). The development of a second population of circulating RBCs with a mean corpuscular volume of 154 cu mu suggests the emergence of an abnormal clone of marrow erythrocyte precursors.
