Abstract
We report a case of chronic myelogenous leukemia (CML) associated with pronounced peripheral lymphadenopathy, with the cells having the philadelphia (Phl) chromosome and T-cell features. A 23-year-old man who was diagnosed as having CML and treated with busulfan was admitted to our hospital because of increasing hepatosplenomegaly and pronounced lymphadenopathy. An axillary lymph node biopsy disclosed that the malignant cells formed rosettes with neuraminidase-treated sheep red blood cells (En) (95.0%) and were positive for Leu 1 (91.8%). Of the cytochemical reactions, peroxidase was negative and periodic acid-Shiff, acid alpha-naphthyl acetate esterase and beta-glucuronidase were all positive. The karyotype of the bone marrow cells was 46 XY Phl positive (22q-), and that of the lymph node cells was 51 XY Phl positive +8, +9, +18, +19, +21, 22q-. He was treated with various anti-leukemic agents and irradiation. Despite such treatments, he died of pneumonia. This is a report of a CML patients with blast crisis and tumor formation characterized by T-cell features.
