[Drug-induced sarcoidosis-like reaction due to dasatinib in the lung of a patient with chronic myeloid leukemia].

The patient was a 54-year-old woman with chronic myeloid leukemia. Ten months after treatment with dasatinib, she developed a cough. Imaging studies showed ground-glass patterns in the lower lung fields of both lungs, which led to suspicion of drug-induced lung injury and prompted discontinuation of dasatinib. A transbronchial lung biopsy showed epithelioid granuloma without necrosis in the alveolar region. There were no other systemic symptoms or signs to support a diagnosis of sarcoidosis. Fifteen days after withdrawal of dasatinib, both the cough and X-ray findings improved. Granulomatous tissue was detected on lung biopsy, which indicates that drug-induced sarcoidosis-like reaction (DISR) may cause interstitial lung injury as a respiratory complication of dasatinib treatment. Case reports of DISR following administration of immune checkpoint inhibitors and immunomodulatory drugs have recently become more frequent. Here we report a case of dasatinib-induced DISR with a review of the literature.
