Summary Telomeric fusion, a rare phenomenon, was observed in malignant cells from the peripheral blood of an 18-year-old male with rapidly progressive pre-T-cell acute lymphoblastic leukemia (ALL). Only two comparable cases, both with B-cell ALL, have been reported with telomeric fusion in neoplasia. All of the leukemic cells examined from our patient had two chromosome abnormalities consisting of partial triplication (trp) of chromosome 2 and a derivative chromosome 3. Approximately a third of the leukemic cells showed in addition telomere-telomere fusions. These involved the telomeric regions of 1p, 2p, 4q, 5q, 7q, 10q, 11q, 12p, 15p, 21p, and Xq and 3p of the derivative (3). The findings in this case suggest that telomeric fusion may function as a mechanism for the development of chromosome rearrangements that may play a role, albeit rarely, in human neoplasia.
