Rhabdomyosarcoma

Types

The three main types of rhabdomyosarcoma are:

Botryoid Rhabdomyosarcoma — This form often occurs in hollow organs, such as the bladder, vagina and uterus. It's often seen in infants and toddlers.

Embryonal Rhabdomyosarcomas (ERMS) — The most common type of rhabdomyosarcoma, it typically occurs in children. Botryoid and spindle cell rhabdomyosarcoma are two variants of this form and tend to have better prognosis than ERMS.

Alveolar Rhabdomyosarcomas (ARMS) — This type of rhabdomyosarcoma typically affects older children and teenagers. Malignant cells normally affect large muscles forming hollow spaces (alveoli).
