A case of peroxidase-positive acute leukaemia expressing only T lineage lymphoid markers.
We report the clinical presentation and the morphological, immunophenotypic, cytogenetic and molecular genetic characteristics of a 14 1/2-year-old boy who had French-American-British (FAB) type M1 acute non-lymphocytic (ANLL) leukaemia with a common T-ALL immunological phenotype, with no myeloid associated antigen, either on the membrane or in the cytoplasm. ALL-directed induction therapy induced complete remission.
