title: Adult T-cell leukemia with an unusual phenotype, Leu-2a positive and Leu-3a negative.
abstract: A case of adult T-cell leukemia (ATL) with an unusual phenotype is presented. Leukemia cells of this patient reacted with anti-Leu-2a monoclonal antibody, although most of ATL cases are reported to show the phenotype of helper/inducer T-cell. It is indicated that the surface phenotype of ATL is rather heterogeneous.
