Fatal carbamazepine induced fulminant eosinophilic (hypersensitivity) myocarditis: emphasis on anatomical and histological characteristics, mechanisms and genetics of drug hypersensitivity and differential diagnosis.

The most severe adverse reactions to carbamazepine have been observed in the haemopoietic system, the liver and the cardiovascular system. A frequently fatal, although exceptionally rare side effect of carbamazepine is necrotizing eosinophilic (hypersensitivity) myocarditis. We report a case of hypersensitivity myocarditis secondary to administration of carbamazepine.
