Desmoid tumor

Desmoid tumor is a rare, noncancerous (benign) growth that occurs in the fibrous tissue that forms tendons and ligaments, usually in the arms, legs or midsection, but also sometimes in the head and neck.

Signs and Symptoms

The signs and symptoms of a desmoid tumor may vary based on its size and location. Some people with desmoid tumors experience no symptoms at all. When symptoms do occur, they may include:

• A noticeable lump or swelling
• Pain or soreness caused by the tumor pressing on nerves or muscles
• Changes in bodily functions depending on the tumor's location, such as bowel obstruction or problems with urination

Causes

The exact cause of desmoid tumors is unknown. They can occur spontaneously or can be associated with certain familial syndromes such as Gardner's syndrome. Some research suggests that physical trauma or surgery may trigger their growth in some people.

Diagnosis

Diagnosis of a desmoid tumor typically involves a physical examination, imaging tests such as MRI or CT scan, and a biopsy to confirm the diagnosis.

Treatment

Treatment options for desmoid tumors include surgery, radiation therapy, and medications such as nonsteroidal anti-inflammatory drugs (NSAIDs), hormonal therapy, and chemotherapy. The choice of treatment depends on the size and location of the tumor, whether it's causing symptoms, and the patient's overall health.

Prognosis

Desmoid tumors do not spread (metastasize) to other parts of the body. However, they can invade nearby tissues and can be difficult to remove completely with surgery. Even after successful treatment, desmoid tumors can come back (recur).
