title: [Acute myelomonocytic leukemia with inv (16) (p13 q22) disappeared abnormal karyotype during complete remission].
abstract: A 21-year-old man was admitted to our hospital because of anorexia and general malaise in July, 1988. On admission, the white blood cell count of 18,600/microliters with 72% leukemic cells. The bone marrow aspirate showed 76.8% immature monocytes, 10% mature and immature eosinophils. Leukemic cells were 66.6% myeloperoxidase positive cells, and 20.6% naphthylbutyrate esterase positive cells. The lysozyme activity in urine was high. Cytogenetic analysis revealed the presence of 46 XY inv (16) (p13 q22). Under the diagnosis of acute myelomonocytic leukemia with eosinophilia (M4Eo) associated with inv (16) (p13 q22), one course of DCMP induction therapy was performed. After complete remission, the bone marrow aspirate showed disappearance of inv (16) (p13 q22), and associated with decreased residual leukemic cells.
