phenethicillin and Myocarditis

We present the case of a 38-year-old man who developed acute myopericarditis, mimicking acute myocardial infarction, as manifested by electrocardiographic, echocardiographic alterations and elevated cardiac enzymes complicating Lancefield group A beta-hemolytic streptococcal tonsillitis. After receiving oral penicillin, the clinical recovery was complete. Fever, tachycardia and chest discomfort resolved within a few days. Furthermore, enzyme levels and C-reactive protein returned to normal within eight days.
