CSF cytology of a patient with conversion of an acute lymphatic leukemia to an acute eosinophilic leukemia.
The course of leukemic disease in a male adolescent with meningeal leukemia is described. The bone marrow aspirates showed a conversion from an acute lymphatic leukemia to an eosinophilic leukemia. Four weeks after the peripheral shift of phenotype two different cell clones were detected in one CSF smear. While under ultrahigh dose araC therapy the patient died 3 months after conversion. Possible explanation for the shift of phenotype and the peculiar leptomeningeal infiltration are discussed.
