Mesenteric and abdominal wall desmoid tumors
are usually associated with familial adenomatous polyposis, which is caused by germline mutations in the adenomatous polyposis coli gene.

Other cutaneous and subcutaneous lesions that are considered in the differential diagnosis include leiomyoma, hemangiopericytoma, fibrous hamartoma of infancy, cutaneous inflammatory pseudotumor, desmoid tumor
, nodular fasciitis, plexiform fibrohistioeytic tumor, neurofibroma, and dermatomyofibroma.
