Abstract
The patient was twenty-one-year-old female who had considerable promylocytes in her peripheral blood and bone marrow.
She noticed fever and painful ulcer of the anal area at onset, and laboratory examination showed anemia, leukopenia, thrombocytopenia and elevated erythrocyte sedimentation rate with no bleeding tendency. She had remission temporarily by adrenocorticosteroid and antiplasmin, and five months later the relapse occurred. On autopsy, microscopic examination revealed extensive infiltration of promyelocytes in bone marrow, spleen, liver and lung, and infectious foci in these organs except bone marrow.
Comparison with the features of Hillestad's acute promyelocytic leukemia was discussed.
