Pelvic fibromatosis, also known as desmoid tumor, isa benign neoplasm with no metastatic potential [1].It accounts for about 0.03% of all neoplasms [2]. Pathophysiologically, it is a deep, infiltrative fibroproliferativeprocess involving the fascia and muscle aponeurosis.The mean age at the time of diagnosis is 41.3 years[3]. The most common sites are the anterior abdominalwall and shoulder girdle. Spread of aggressive fibromatosis can cause compression of the intestine, bladder,ureter, vagina, and pelvic nerves and vessels, leading toits symptomatology, morbidity and mortality. It is highlyassociated with female sex [3], surgery or trauma (4-foldrisk), pregnancy, familial polyposis coli (10–15% ofthe cases) [4,5] and Gardner’s syndrome. The reportedrecurrence rate after surgery is 45% [6].
