title: Translocation (1;14)(p34;q11) and trisomy 8 in a T-cell acute lymphoblastic leukemia patient.
abstract: A case of T-cell acute lymphoblastic leukemia (T-ALL) in a 25-year-old man cytogenetically characterized by a t(1;14)(p34;q11) and trisomy 8 is reported. These chromosome abnormalities were observed in 82% of the analyzed metaphases. Fluorescence in situ hybridization (FISH) with a probe for the centromere of chromosome 8 was used to correlate cellular morphology in bone marrow (BM) cells with May-Grünwald-Giemsa smears and the cytogenetic alterations. By FISH analysis, trisomy 8 (and presumably the associated t[1;14]) was demonstrated only in lymphoid blast cells but not in the rest of the cells belonging to other hematopoietic lineages.
