In the case of osteosarcoma, secondary acute myeloid leukemia which occurs as the consequences of the complication of chemotherapy, is rare. We are reporting the case that we have recently experienced in the laboratory. A case of secondary acute myeloid leukemia have been occurred to among 77 patients who have been diagnosed as osteosarcoma and received chemotherapy from 1995 to 1999. This case was compared with the cases of other reports for the analysis of its cause and results. A 17-year-old man was diagnosed as a osteosarcoma in the distal part of femur, and recieved chemotherapy. Within 28months, the hematological analysis of the case indicated the severe increase in the number of the white cell (over 200,000) and the profound decrease in the number of platelets. A test of bone marrow needle aspiration and peripheral blood smear showed a tremendous increase in the number of the monocytoid immature cell, which mostly are blasts and promonocytes. Due to this clinical results, the case was diagnosed as the secondary acute myeloid leukemia after the chemotherapy. The frequency of occurrence of secondary acute myeloid leukemia after chemotherapy is quite phenomenal. But the disease could be fatal leading to a high rate of morbidity and mortality without early diagnosis and treatment. Hence, an enough recognition of the possibility of its development, the periodical observation and inspection after chemotherapy and an immediate treatment in the case of occurrence are essential.
