title: [Prominent lymphadenopathy and double Ph1 chromosomes as initial and recurrent manifestations of chronic myelogenous leukemia in blast crisis: report of a case and review of the literature].
abstract: A 60-year-old woman was admitted because of fatigue. Physical examination revealed prominent peripheral lymphadenopathy, marked tonsillar swelling and hepatosplenomegaly. The leukocyte count was 68,900/microliters with 75% lymphoid blasts and 5% basophils. The karyotype of the blood cells was 46, XX, Ph1/47, XX, Ph1, +Ph1. The diagnosis of CML in blast crisis was made. After chemotherapy using adriamycin, cyclophosphamide, vincristine, and prednisolone (CHOP), lymphadenopathy and splenomegaly reduced and lymphoid blasts disappeared from the blood and bone marrow. At that time only single Ph1 (46, XX, Ph1) clone was detected in her bone marrow. Four months later, hematological relapse accompanied by lymphadenopathy occurred and DNA analysis of the blasts showed the rearrangement of bcr gene. The simultaneous chromosomal analyses of the blood, bone marrow and lymph node revealed that almost all cells examined had the karyotype "47, XX, Ph1, + Ph1". In spite of repeated chemotherapy the patient did not improve and died. This case suggests a relationship between lymphadenopathy and double Ph1 chromosomes in CML.
