A case of acute eosinophilic granulocytic leukemia with PML-RAR alpha fusion gene expression and response to all-trans retinoic acid.
A typical case of eosinophilic granulocytic leukemia with PML-RAR alpha fusion gene expression is reported. The patient achieved complete remission after oral administration of all-trans retinoic acid without any exposure to cytotoxic agents. The facts strongly suggest that the genetic event occurred at the level of pluripotent stem cells.
