[Neonatal cardiac rhabdomyoma: case report and clinico-epidemiologic considerations].

Primary cardiac tumors are very infrequent at all ages; the most frequent in the pediatric age is rhabdomyoma. This tumor is associated with tuberous sclerosis in 37 to 80%, with a frequency of 1 for each 40,000 live newborns. This case is about a newborn, who in the immediate postnatal period presented pansystolic murmur, grade IV cardiomegaly, electrocardiographic changes of biventricular hypertrophy and heart failure. Echocardiogram and magnetic resonance images showed several tumors in the septum and in ventricular walls; histopathology study of the heart, confirmed the diagnosis. The diagnosis of tuberous sclerosis was made clinically (seizures, hypomelanotic macules) and with the image of parenchymal hypodense areas. In our country there is little information about both diseases, that's why we made a review of the incidence, diagnosis, prognosis and treatment.
