Abstract

A 30-year-old male underwent percutaneous coronary intervention for acute myocardial infarction. The patient developed fever after the operation, and CT revealed a 6.4 cm × 4.8 cm soft tissue mass around the proximal segment of the right coronary artery, between the left main pulmonary artery and the left heart. The density of the mass was not uniform; the boundary was unclear, with invasion of the pericardium, left coronary artery, some branches of the left pulmonary artery and vein, and the left heart. The pathological examination at the superior hospital suggested that the mass was mainly composed of spindle cells with slightly transparent cytoplasm. Immunohistochemistry showed HMB-45 (+), EMA (±), SMA (+), MDM2 (+), and CD63 (partial +). No MDM2 gene amplification was found by Fluorescence in situ Hybridization (FISH). This is the first reported case of acute myocardial infarction caused by coronary artery compression by myocardial Perivascular Epithelioid cell tumor (PEComa), which differs from previously reported cases of pericardial/ myocardial PEComas.
