Intrauterine rhabdomyoma of the heart. A case report.

Abstract

Primary cardiac tumors are rare findings in adults and children. A case is presented in which ultrasound examination revealed an incredibly large tumor in the heart of a fetus at 24 weeks. Tumor filled the whole left ventricle. Histology and immunohistochemistry were indicative of rhabdomyoma, i.e., a hamartoma that is often associated with tuberous sclerosis.
