ABSTRACT
We report a case of a 49-year-old Japanese man, who was admitted to our hospital because of severe dyspnea. He was found to have severely low serum folate and megaloblastic anemia, which was at first suspected to cause his dyspnea. It was assumed that severely low serum folate might be related to his malnutrition, probably caused by habitual alcohol consumption. He died in several days because of acute respiratory distress syndrome. Autopsy revealed diffuse alveolar damage (DAD) in the lungs and systemic lymph node swelling by EBV-positive diffuse large B-cell lymphoma, in addition to megaloblastic anemia in the bone marrow. Together with histological hemophagocytosis and high level of serum iron and ferritin, DAD was considered to be caused by hypercytokinemia triggered by the presence of EBV-positive diffuse large B-cell lymphoma. On the other hand, pathological findings suggestive of habitual alcohol consumption were not apparent. We considered that low serum folate in this case was not by the low intake but by increased consumption of folate by rapid progression of the lymphoma.
