WHAT IS SOFT TISSUE SARCOMA?
Soft tissue sarcoma starts in cells that develop into soft tissue. This is called mesenchymal cells. Soft tissue sarcomas most often form in the arms and legs. They can also form in the torso area as well as the head, neck, the space in front of the lower spine, and behind the abdominal cavity. In addition, they can be found in muscles, fat, and nerves.
​
Soft tissue sarcoma is described as a group of 50 cancers that form in the soft tissue.
Common and specific types include (not an exhaustive list):
Gastrointestinal Stromal Tumor (GIST)
Leiomyosarcoma including Uterine Leiomyosarcoma
Rhabdomyosarcoma
​
Perivacular epitheliod cell neoplasms (PEComas) are rare soft tissue tumors. They often form around small blood vessels (perivascular spaces) in various body parts such as the lungs, GI tract, kidneys, liver, and uterus.
