Description : Hereditary desmoid disease usually presents as an extraintestinal manifestation of
familial adenomatous polyposis (FAP; 175100), also known as Gardner syndrome, which
is an autosomal dominant disorder caused by germline mutation in the APC gene. The
desmoid tumors are usually intraabdominal and, although benign, can be locally aggressive
and result in significant morbidity. Desmoid tumors can also arise sporadically (Couture
et al., 2000).;
