Characteristic pulmonary findings in an autopsy case of a 46‐year‐old female who presented heavy dyspnea as her chief complaint after 3 months of busulfan therapy for chronic myeloid leukemia were reported. The pulmonary findings were classified into four types: I. alveolar proteinosis type, II. intra‐alveolar fibrosis type, III. interstitial fibrosis type, and IV. lipid pneumonia type with cholesterol granuloma. No other case with various findings like this case has been previously reported. It was considered that type I is the basic type, type II is a type that developed from type I, type III is a type with interstitial cell infiltration and fibrosis and type IV is a lipidrich variant of type I. A large lamellar body was first found in the granular material of type I. It is supposed that such a body consists of osmiophllic body which originated from type B alveolar epithelial cells and blood plasma.
