Conditions We Treat


Sarcoma is a type of cancer that originates in bone or in one of the soft tissues. Soft tissues in this context include muscles, blood vessels, tendons, fat, nerves, and deep skin tissues.  Almost half of soft tissue tumors start in the arms or legs.  Other soft tissue tumors arise in the torso.  More rarely, soft tissue tumors start in the head and neck regions, or within other organs, such as the liver, lung, kidney, uterus, breast, and gastrointestinal tract.  Sarcoma occurs in both adults and children.

The most common soft tissue sarcomas are:

  • Leiomyosarcoma
  • Liposarcoma

Other common soft tissue sarcomas are:

  • Angiosarcoma
  • Synovial sarcoma
  • Rhabdomyosarcoma
  • Malignant peripheral nerve sheath tumor
  • Spindle cell sarcoma
  • Ewing’s sarcoma
  • Gastrointestinal stromal tumors (GIST)
