A case of acute eosinophilic pneumonia after unrelated bone marrow transplantation / 대한내과학회지

Pneumonia is one of important complications after allogeneic bone marrow transplantation (BMT). It is essential to disclose the cause of pneumonia because the treatment depends on the cause. The cause of pneumonia which BMT recipients develop can be infectious as well as noninfectious in origin. Acute eosinophilic pneumonia is a very rare cause of noninfectious pneumonia after BMT. We here report a 42-year-old woman with acute myelogenous leukemia (AML, M4) who developed acute eosinophilic pneumonia on 160 days after unrelated BMT. She was diagnosed by bronchoalveolar lavage and was dramatically improved after steroid treatment.
