A rhabdomyoma is a benign tumor of striated muscle Rhabdomyomas may be either "cardiac" or "extra cardiac" occurring outside the heart Extracardiac forms of rhabdomyoma are sub classified into three distinct types: adult type, fetal type, and genital type

Cardiac rhabdomyomas are the most common primary tumor of the heart in infants and children It has an association with tuberous sclerosis1 In those with tuberous sclerosis, the tumor may regress and disappear completely, or remain consistent in size

It is most commonly associated with the tongue,2 and heart,3 but can also occur in other locations, such as the vagina4

Malignant skeletal muscle tumors are referred to as rhabdomyosarcoma Only rare cases of possible malignant change have been reported in fetal rhabdomyoma The differential diagnosis in the tongue includes ectomesenchymal chondromyxoid tumor5
