Overview
Aggressive fibromatosis is a rare condition marked by the presence of desmoid tumors. Desmoid tumors are tumors that arise from cells called fibroblasts. Fibroblasts are found throughout our body and their main function is to provide structural support and protection to the vital organs such as lung, liver, blood vessels, heart, kidneys, skin, intestines etc. and they also play a critical role in wound healing. When fibroblast cells undergo mutations they can become cancerous and become desmoid tumors (also known as "aggressive fibromatosis"). Desmoid tumors can arise in virtually any part of the body. These tumors often occur in women in their 30's, but can occur in anyone at any age. Desmoid tumors can be slow growing or extremely aggressive. These are slow-growing musculoaponeurotic tumors without any metastatic potential. However, aggressive fibromatosis is locally aggressive. When they are aggressive they can cause life threatening problems or even death when they compress vital organs such as intestines, kidney, lungs, blood vessels, nerves etc. Most cases are sporadic, but some are associated with familial adenomatous polyposis (FAP). Approximately 10% of individuals with Gardner's syndrome, a type of FAP with extracolonic features, have desmoid tumors.[1]
Historical Perspective
Classification
Desmoid tumor may be classified according to etiology into 5 subtypes.[2]
Pathophysiology
Desmoid tumor may occur as part of Gardner syndrome. A minority of desmoid tumors are associated with Turcot syndrome, Familial adenomatous polyposis, and estrogen therapy.[3]
Causes
There are no established direct causes for desmoid tumor.
Differentiating Desmoid tumor from other Diseases
Desmoid tumor must be differentiated from acute hematoma, lymphoma, and fibrosarcoma.[2]
Epidemiology and Demographics
Desmoid tumor occurs in less than 0.03% of all tumors. The incidence of desmoid tumor is approximately 30 per 100,000 individuals worldwide. Females are more commonly affected with desmoid tumor than males. Desmoid tumor commonly affects individuals between 20 to 40 years of age.[4][2]
Risk Factors
Risk factors for desmoid disease amongst FAP patients include female sex, a 3' APC mutation, a positive family history and a history of previous abdominal surgery.[5]
Natural History, Complications and Prognosis
If left untreated, desmoid tumor produces few symptoms early in the course. Common complications of desmoid tumor include progression to agressive fibromatosis, involvement of intra abdominal viscera and metastasis. The prognosis varies with the associated disease of desmoid tumor. Desmoid tumor associated with FAP has the most unfavorable prognosis.
History and Symptoms
Symptoms of desmoid tumor include uncharacteristic pain, abdominal mass, nausea, and vomiting.
Physical Examination
Common physical examination findings of desmoid tumor include abdominal tenderness, pallor, and elevated temperature.[2]
Laboratory Findings
CT
MRI
