11;14 translocation in childhood T-cell acute lymphoblastic leukemia.

No consistent chromosome abnormalities have been reported so far in T-cell lymphoma-leukemia. We report here two children suffering from T-cell acute lymphoblastic leukemia (ALL) with t(11;14)(q13;p11). Even though the breakpoints we claim are different from those in a recent report, we believe that their cases and ours have the same abnormality and that patients with this abnormality constitute a distinct subgroup of T-cell ALL positive for sheep erythrocyte receptor (E+) in children.
