Atypical localization, atypical clinical course, unexpected age: Myxoma

The incidence of cardiac tumors in infants and the pediatric population is 0.08% (1). Rhabdomyoma is the most common tumor in the neonatal period (1, 2). However, myxoma is the most common primary tumor that is frequently localized in the left atrium in the adult population. The incidence of myxoma in the pediatric population is 20.2%. In fact, myxoma equally affects both atria during the pediatric ages (3).
