What Is Rhabdomyosarcoma?

Q:
What is rhabdomyosarcoma?

A:
Rhabdomyosarcoma (RMS) is an aggressive and highly malignant form of cancer that develops from skeletal muscle cells that have failed to fully differentiate.

RMS can occur at any age, but it most often affects children. Adults are more likely to have faster-growing types of RMS and to have them in parts of the body that are harder to treat.

RMS may arise anywhere in the body, but it is more likely to start in the:

  • Head and neck area
  • Urinary system, such as the bladder
  • Reproductive system, such as the vagina, uterus or testes
  • Arms and legs
  • Trunk (chest and abdomen)

There are several types of RMS:

1. Embryonal rhabdomyosarcoma (ERMS)

  • Botryoid rhabdomyosarcoma
  • Spindle cell rhabdomyosarcoma

2. Alveolar rhabdomyosarcoma (ARMS)

3. Anaplastic rhabdomyosarcoma and undifferentiated sarcoma
