Abstract

We report a 62-year-old man with acute myelomonocytic leukemia with bone marrow eosinophilia (M4Eo), and a deletion of the long arm of chromosome 7. The patient presented with pancytopenia, which shortly after evolved to overt leukemia. There was no response to the daunorubicin-cytosine arabinoside (Ara-C) regimen, and a remission achieved with amsacrine (AMSA)-Ara-C lasted only for a short time. On relapse, a peculiar skin rash accompanied the hematologic picture. While ANLL with chromosome 7 abnormalities usually carries adverse prognosis, patients with M4Eo (which is usually associated with chromosome 16 abnormalities) do better. The patient described here examplifies that M4Eo may be associated with del(7)(q22), and that it is the chromosomal abnormality rather than the type of leukemia that might determine the clinical outcome.
