Embryonal rhabdomyosarcoma is the most common type of rhabdomyosarcoma. It can form in the head and neck area, or in the genital or urinary organs.
Most common in the teenage years, alveolar rhabdomyosarcoma occurs most often in the arms, legs, chest, abdomen or genital area.
Botryoid rhabdomyosarcoma is a type of embryonal rhabdomyosarcoma and accounts for about 5 to 10% of all rhabdomyosarcoma cases. It occurs most often in children between birth and 15 years.
Pleomorphic rhabdomyosarcoma usually occurs in adults.
