title: Hypoplastic myelodysplastic syndrome-a clinical, morphologic, or genetic diagnosis?
abstract: We report a middle-aged female with an 11-year history of nonprogressive pancytopenia and severely hypoplastic marrow with minimal morphologic dysplasia. A diagnosis of hypoplastic myelodysplastic syndrome (MDS) was made because of the finding of a persistent clonal abnormality, del(13)(q12q14), and the subsequent demonstration of a single Auer rod-containing blast in the peripheral blood smear. The case illustrates the problems in the differentiation between aplastic anemia and hypoplastic MDS.
