Title: A pericentric inversion of chromosome 16 is associated with dysplastic marrow eosinophils in acute myelomonocytic leukemia. Author: Tantravahi R, Schwenn M, Henkle C, Nell M, Leavitt PR, Griffin JD, Weinstein HJ. Journal: Blood; 1984 Apr; 63(4):800-2. PubMed ID: 6584185. Abstract: Cytogenetic studies were performed in 18 consecutive children with acute nonlymphocytic leukemia (ANLL) between 1981 and 1983. Three children with acute myelomonocytic leukemia (AMMoL; M4, FAB classification) had the following unique bone marrow morphology and cytogenetic abnormality: eosinophilic precursors with dysplastic violaceous granules and a pericentric inversion of chromosome 16. Surface marker analysis of leukemic cells from these patients, using a panel of monoclonal antibodies, revealed the expression of a series of monocyte markers. The association of an inversion of chromosome 16 with abnormal eosinophil morphology in the M4 subtype of ANLL appears to represent a unique subgroup of patients.[Abstract] [Full Text] [Related] [New Search]
