Extra-abdominal desmoid tumors
Desmoid tumors are fibrous in nature, much like scar tissue.
Extra-abdominal desmoid tumors are very rare tumors. Although technically benign (or noncancerous) because they do not metastasize (spread) to other parts of the body, demoids can grow aggressively in the area the appear. Rarely fatal, desmoid tumors often grow around other surrounding muscle, tendons, joints, bones, nerves, vessels and arteries which can make them result in pain and notable disability.
Desmoids often grow slowly, but can grow more quickly, particularly when exposed to heat (radiation) or incomplete surgical removal.
Desmoids can appear in people of any age, though they occur most often in older children and young adults up to 40 years old. They appear more frequently in males than females.
