Huge pelvic fibromatosis encroaching on the urinary bladder. A case report

A patient with a huge pelvic fibromatosis, a form of intra-abdominal desmoid, encroaching on the urinary bladder is described. Because of its rarity, there is frequently a lack of diagnostic awareness of this tumor, particularly in the gynecological or urological patient. Although this tumor is a locally invasive benign tumor which dose not metastasize, management by radical tumor excision without the sacrifice of the major pelvic nerves and vessels is mandatory, since this tumor has generally a high postsurgical recurrence rate.
