Acute myocardial infarction as presenting symptom of thymoma with compression on a coronary stent

We report the clinical case of a patient with acute myocardial infarction due to coronary stent compression as first manifestation of a large thymoma. The patient underwent a coronarography and thrombus aspiration + plain old balloon angioplasty restoring the stent patency. The mass resection was performed through left robotic-assisted thoracic surgery (RATS), resulting in a type A thymoma pT1a, IIb Masaoka-Koga. An uncommon presentation led to early diagnosis and treatment of a thymoma with both oncological and functional significance.
