[A Case of Chronic Myelogenous Leukemia That Developed Fibrous Pericarditis Owing to Nilotinib Use].

ABSTRACT

A 64-year-old man was diagnosed with chronic-phase chronic myelogenous leukemia(CML)in May 2009. He was treated with imatinib and achieved complete cytogenetic response(CCyR)in 2 months. After 4 months of treatment, he developed interstitial pneumonia and became intolerant to imatinib. He was then switched to nilotinib from October of the same year. In June 2013, he was diagnosed with drug-induced pericarditis resulting from nilotinib use, and thus, nilotinib was discontinued. Subsequently, he was followed up without specific treatment for CML. In January 2014, he was admitted to the Dept. of Cardiovascular, Renal and Metabolic Medicine at our hospital because of heart failure. After examinations of cardiac function, he was diagnosed with constrictive pericarditis. Therefore, pericardiolysis was performed by the Dept. of Cardiovascular Surgery at our hospital. Pathologic findings showed hyaline-like fibrous tissue proliferation in the pericardium, which was diagnosed as fibrous pericarditis induced by nilotinib. We report a case of chronic myelogenous leukemia that developed fibrous pericarditis owing to nilotinib use.
