Desmoid tumours (also called deep or aggressive fibromatoses) are potentially life-threatening fibromatous lesions. Hereditary desmoid tumours arise in individuals affected by either familial adenomatous polyposis (FAP) or hereditary desmoid disease (HDD) carrying germline mutations in APC. Most sporadic desmoids carry somatic mutations in CTNNB1. Previous studies identified losses on 5q and 6q...

Background: Many patients with familial adenomatous polyposis (FAP) die from desmoid tumours which can arise spontaneously but often appear to be surgically induced by prophylactic colectomy. FAP results from germline adenomatous polyposis coli (APC) gene mutations and desmoids arise following biallelic APC mutation, with one change usually occurring distal to the second b-catenin binding/degra...

Desmoids are rare, benign fibromatous lesions, which can arise in patients with familial adenomatous polyposis (FAP), a disorder caused by germline adenomatous polyposis coli (APC) gene mutation. This study investigated the risk of desmoids in FAP, the relation between specific APC gene mutations and desmoid formation, and the clinical characteristics ofFAP patients with desmoids. Eighty three ...

BACKGROUND Many patients with familial adenomatous polyposis (FAP) die from desmoid tumours which can arise spontaneously but often appear to be surgically induced by prophylactic colectomy. FAP results from germline adenomatous polyposis coli (APC) gene mutations and desmoids arise following biallelic APC mutation, with one change usually occurring distal to the second beta-catenin binding/deg...

Desmoids are rare tumors resulting from the proliferation of fibroblasts. They occur in association with familial adenomatous polyposis (FAP), but they may also occur in the post-traumatic peri-partum or post-abdominal surgery setting, and a few present spontaneously. Presenting features of desmoids are protean and largely relate to the anatomical area of involvement. We describe a 50 year old ...

We report here a review of the current medical literature on pregnancy associated desmoids, including 10 cases of our own. The pertinent findings are that a large percentage of desmoids in females arise in and around pregnancy. Most occur in the abdominal muscles, particularly the right rectus abdominus, perhaps related to trauma from abdominal stretching and fetal movement. While these tumors ...

Desmoid tumors describe a rare monoclonal, fibroblastic proliferation characterized by a variable and often unpredictable clinical course. Although histologically benign, desmoids are locally invasive and associated with a high local recurrence rate, but lack metastatic potential. On the molecular level, desmoids are characterized by mutations in the β-catenin gene, CTNNB1, or the adenomatous p...

HYPOTHESIS Abdominal wall tumors, though clinically similar, have varying degrees of biological behavior. DESIGN Retrospective review of prospective databases. SETTING Memorial Sloan-Kettering Cancer Center. PATIENTS Eighty-five patients with abdominal wall soft tissue tumors. MAIN OUTCOME MEASURES Primary endpoints included time to first local recurrence, distant metastases, and diseas...
