The relationship between acute coronary syndrome and inflammation: a case of acute myocardial infarction associated with coronary involvement of Sweet's syndrome.

Sweet's syndrome is characterized by skin lesions and fever. One of the rare extracutaneous manifestations of Sweet's syndrome is cardiovascular involvement including coronary artery occlusion. In this article, we present a case of acute myocardial infarction associated with exacerbation of Sweet's syndrome. Coronary angiography has demonstrated normal left coronary arterial system and the occlusion of distal right coronary artery. The patient underwent successful balloon angioplasty and subsequent coronary artery stenting. The presence of coronary ectasia, aneurysm and coronary occlusion of right coronary artery caused us to hypothesize that the coronary involvement including ectasia, aneurysm and occlusion might be associated with hyperreactive inflammatory response secondary to exacerbations of Sweet's syndrome.
