Cardiac rhabdomyoma presenting as sudden infant death syndrome.

A case of cardiac rhabdomyoma presenting as sudden infant death in a four-and-one-half month-old infant is reported. The child was the product of an essentially uncomplicated pregnancy and enjoyed good health before his unexpected, sudden death. Autopsy examination revealed the presence of multiple cardiac lesions which histologically were diagnosed as rhabdomyomas. Death was attributed to fatal cardiac arrhythmia caused by the tumor. To the authors' knowledge this represents the first reported case in the forensic science literature of death as a result of cardiac rhabdomyoma presenting as sudden infant death syndrome (SIDS).
