title: [Relapse of acute monocytic leukemia present with skin and tracheal involvement].
abstract: A 34 year-old female was admitted because of anemia and leukopenia. Her bone marrow contained abundant blastic cells, which were histochemically positive for peroxidase and alpha-naphthyl butyrate esterase, but negative for ASD chloroacetate esterase. She was diagnosed as acute monocytic leukemia (FAB, M5a). Complete remission was achieved after the administration of BHAC, daunorubicin, 6MP and prednisolone, and she was discharged after consolidation therapies. But shortly later, she noticed hoarseness and erythematous nodules on her breast and abdomen. Though the examinations of peripheral blood and bone marrow did not show any abnormality, hoarseness rapidly worsened and she complained of dyspnea. X-ray and CT scan demonstrated narrowing of the trachea under the cricoid cartilage, and trans-tracheal biopsy revealed leukemic involvement. In addition, erythematous skin lesion showed the infiltration of leukemic cells by biopsy. Although radiation and chemotherapy was initiated, she died of pneumonia. We tried to discuss the laryngo-tracheal and skin involvement of acute monocytic leukemia as early symptoms of relapse.
