Abstract excerpt
FMS-like tyrosine kinase 3 (FLT3) mutation in T lymphoblastic leukemia/lymphoma (T-LL) is rare (∼4%) and reported only in cases with CD117 expression. This study aimed to identify the immunophenotypic features that may predict FLT3 mutations. We report 3 (43%) of 7 CD117(+) T-LL cases harboring FLT3-internal tandem duplication mutation. Compared with 4 FLT3-unmutated cases, all 3 FLT3-mutated cases had a distinct...
