Cardiac rhabdomyoma--a case report.

Cardiac tumors are rare in neonates, most are benign hamartomas (rhabdomyomas) of the muscle cells. Due of large size, they may cause homodynamic instability and even death in neonatal period. They are rarely diagnosed prenatally and are found in multiple forms. In ∼50% of the cases, rhabdomyoma is associated with tuberous sclerosis.
