Conversion of polycythemia vera to refractory anemia with hyperplastic bone marrow

P S Mitrou et al. Blut. .

Abstract

Clinical and morphologic findings in the conversion of treated polycythemia vera to pancytopenia with hyperplastic bone marrow (refractory anemia or pancytopenia with hyperplastic bone marrow) are described in light of our own observation. The nomenclature associated with this condition (pancytopenia, chronic erythroleukemia, preleukemia) is not uniform, whereas the morphologic findings are virtually identical. Some patients subsequently develop acute leukemia. The prognosis in cases of refractory anemia with hyperplastic bone marrow following polycythemia vera is, independent of the subsequent acute leukemia, invariably terminal.
