Abstract
-
We repoarted a rare case of AML atypical M2 who developed granulocytic granulocyte sarcoma in the meninges which was induced complete remission with all-trans retinoic acid (ATRA), daunorubicin and cytosine arabinoside (Ara-C). Morphological and immunophenotypic study of leukemic cells in this patient suggested acute promyelocytic leukemia. However, leukemic clees lacked both t (15;17) and PML-RARalpha gene rearragement, rather showed t (8;21). The patient was diagnosed as AML atypical M2.
