Hidden Mastocytosis in Acute Myeloid Leukemia With t(8;21)(q22;q22). American journal of clinical pathology Johnson, R. C., Savage, N. M., Chiang, T., Gotlib, J. R., Cherry, A. M., Arber, D. A., George, T. I. 2013; 140 (4): 525-535

Abstract

Objectives: To assess the frequency of systemic mastocytosis (SM) in a large series of acute myeloid leukemia (AML) with t(8;21)(q22;q22). Methods: We retrospectively characterized 40 bone marrow aspirate smears and biopsy specimens from patients with AML with t(8;21) for the presence of SM. Cases were assessed for mast cell morphology and immunohistochemistry, as well as KIT exon 8 and 17 mutational assessment by reverse transcription polymerase chain reaction. Results: Four patients met criteria for SM, 1 met criteria for myelomastocytic leukemia, and 8 demonstrated the benign finding of mast cell hyperplasia. Conclusions: We recommend examining all cases of AML with t(8;21) for the presence of SM via morphology, immunophenotyping, and KIT mutational analysis studies.
