Tumors of muscular origin

There are a number of tumors of muscular origin, which overall are relatively uncommon, representing ~2% of benign soft tissue tumors and ~10% of malignant soft tissue tumors .

Pathology

The tumors can be divided according to the type of muscle fiber:

Skeletal muscle origin

• benign
  • rhabdomyoma
    • ​extracardiac (non-cardiac) rhabdomyoma
      • adult rhabdomyoma
      • fetal rhabdomyoma
      • genital rhabdomyoma
    • cardiac rhabdomyoma
• malignant
  • rhabdomyosarcoma
    • embryonal rhabdomyosarcoma subgroup
      • spindle cell rhabdomyosarcoma
      • botryoid rhabdomyosarcoma
      • anaplastic rhabdomyosarcoma
    • alveolar rhabdomyosarcoma
    • pleomorphic rhabdomyosarcoma

Smooth muscle origin

• benign
  • angioleiomyoma
  • deep leiomyoma
  • genital leiomyoma
• malignant
  • leiomyosarcoma
