A 37-year-old man was admitted to the hospital because of gingiva bleeding in January, 1981. He was diagnosed as AML by presence of leukemic cells in peripheral blood smears and bone marrow aspirates.
He was treated with DCMP, but chest X-ray film revealed abnormal shadow in the right upper and middle lobes. In spite of an administration of several antibiotics on the suspicion of pneumonia, abnormal shadow did not improve.
In May, 1981, suddenly, he developed coma after convulsion, followed by right hemiplegia. He died of the respiratory distress five months after the onset of the bleeding tendency.
Autopsy findings revealed right pulmonary haemorrhagic infarction, pulmonary thrombosis, endocarditis, gigantic thrombus in the left atrium and necrotic focus of the left internal capsule with cerebral thrombosis by mucor.
