Unusual Case of Dasatinib-Induced Organizing Pneumonia Pattern, Diagnosed by Lung Biopsy

초록

Dasatinib, a tyrosine kinase inhibitor (TKI), is usually used for chronic myeloid leukemia (CML) and Philadelphia chromosome?positive acute lymphoblastic leukemia. In dasatinib-associated pulmonary toxicities, pleural effusion and pulmonary arterial hypertension have been relatively well known. About interstitial pneumonitis (ILD), a few cases have been reported but there was no organizing pneumonia (OP) pattern in the English literature. Herein, we describe a case of dasatinib-induced OP, diagnosed by lung biopsy.
