Overview
Rhabdomyoma is a benign tumor of striated muscle. Rhabdomyomas are rare and can be classified into cardiac type and extracardiac type.The most common primary benign pediatric tumor of the heart is cardiac rhabdomyoma which can be seen mainly in fetal life and children, second most common primary benign cardiac tumor in children is fibroma. Most tumors regress spontaneously, prognosis depends on the location of tumor and size. Cardiac rhabdomyoma is strongly associated with tuberous sclerosis. Cardiac rhabdomyoma is seen almost always in the pediatric age group and is associated with tuberous sclerosis, neurofibromatosis, and sebaceous adenomas. Extracardiac rhabdomyoma can be divided into three groups (adult, fetal, and genital types) with distinct clinical and morphological differences. The adult type is a slowly growing mass which typically involves the head and neck. Fetal type is seen in the head and neck region. The genital type is almost always found in the vulvovaginal region of older women. Treatment of adult type rhabdomyoma of head and neck depends upon the severity of clinical symptoms. Conservative management or surgery may be necessary depending upon the type and tumor stage.
