title: T cell-derived blast crisis in chronic myelocytic leukemia.
abstract: We describe herein the occurrence of a T cell-derived blast crisis of chronic myelocytic leukemia which presented as a typical T cell leukemia on clinical (thymic mass and high white blood cells) and immunological grounds (T6+ T4+ T8+), with rearranged T cell receptor genes and germ line immunoglobulin genes. A Philadelphia chromosome was detected in all blast cell mitoses. The significance of T cell involvement during the chronic and acute phases of chronic myelocytic leukemia is discussed.
