A 57-year-old man with a long history of smoking was admitted because of a history of abdominal pain lasting 2 weeks. An endoscopy revealed advanced gastric cancer. Four days after a subtotal gastrectomy, his peripheral blood count showed pancytopenia and five percent immature cells. Diagnosis of acute myelocytic leukemia was made by bone marrow examination, cytochemistry, and immunophenotyping. Induction chemotherapy was started and complete remission was achieved. Three months later, the patient suffered a relapse of leukemia and died of pulmonary hemorrhage during reinduction chemotherapy.
