Rhabdomyomas are benign mesenchymal neoplasms exhibiting skeletal muscle differentiation and can be subdivided into cardiac and extracardiac (adult, fetal, and genital) subtypes.
Even though cardiac rhabdomyoma is the most common cardiac tumor identified in infants and children, it is rare. Among extracardiac rhabdomyosarcomas, the adult type is the most frequently encountered.
Cardiac rhabdomyomas present almost exclusively in infants and young children. Adult and genital rhabdomyomas typically affect older adults with a median age of 50–60 years, while fetal rhabdomyomas usually present as congenital masses or in early childhood (Kapadia et al. 1993a, b).
Rhabdomyomas are more common in males than females except for the genital subtype which most often affects females.
Cardiac rhabdomyomas generally present as one or multiple intramural nodules within the ventricles, but lesions may arise in the interventricular septum or atria...
