A 71-year-old man with acute myelogenous leukemia (AML, M2) developed signs of chest oppression, and was diagnosed as having acute myocardial infarction (AMI). At the same time, his leukemia relapsed in association with disseminated intravascular coagulation (DIC). The patient's risk factors for AMI were hyperlipidemia, hyperglycemia, and a history of smoking. ⋯ After chemotherapy, the patient's DIC improved and a second remission was attained. When elderly patients with AML show evidence of DIC, we should be aware of AMI as a possible complication. PTCA is a safe operation for such patients.

A 28-year-old man developed cryptogenic hepatitis in January 1999, and treatment with glycyrrhizic acid improved his liver function. From June, however, pancytopenia began to develop gradually. The patient received G-CSF against leukocytopenia (WBC 1,100/microliter, neutrophils 590/microliter) and was transferred to our hospital in August 1999. ⋯ Immediately after starting combined therapy with ATG, cyclosporin, and G-CSF, his liver function began to improve and was normalized on day 7. Pancytopenia began to ameliorate on day 9, and blood parameters on day 60 were WBC 4,200/microliter (without G-CSF administration), Hb 12.0 g/dl, platelets 9.0 x 10(4)/microliter, and reticulocytes 4.1 x 10(4)/microliter. Although the prognosis of hepatitis-associated aplastic anemia is generally poor, immunosuppressive therapy was markedly effective for both pancytopenia and hepatic dysfunction in the present case.
