Desmoid fibromatosis is a rare but locally aggressive tumor comprised of myofibroblasts. Desmoids do not have the ability to metastasize but can cause significant morbidity and mortality by local invasion. These tumors may occur throughout the body, but are commonly found on the abdominal wall and within the intestinal mesentery. Desmoids in these areas may cause unique clinical problems for ph...

Despite their classification as benign, desmoid tumours are difficult to diagnose and manage. They are prone to recurrence and resection can be debilitating. Rarely, synchronous or metachronous multicentric desmoid tumours occur and may require further excision. Therefore, early detection of recurrence and multicentric tumours is vital. We present a case of metachronous desmoid tumours, and rev...

Fibromatosis is an infiltrative proliferation of fibroblastic and myofibroblastic cells with significant risk for local recurrence, but no metastatic potential. It originates mainly from the fascia or aponeuroses of the abdominal wall muscles or from the muscles of the shoulders and pelvic girdles. Fibromatosis is uncommon in the mammary gland and accounts for less than 0.2% of all primary brea...

Aggressive fibromatosis arising from the retroperitoneum is extremely rare. It may occur in association with previous trauma, abdominal surgery, drugs, Gardner's syndrome, or familial adenomatous polyposis. We report a case of retroperitoneal fibromatosis presenting as a presacral mass with an infiltrating nature, relatively intense enhancement on enhanced computed tomography scanning, and low-...

Intra-abdominal fibromatosis (IAF) may arise either sporadically or in association with familial adenomatous polyposis. The characteristics of fibromatosis are slow-growth, benign histological features, and aggressive local invasion. Surgery remains a reasonable first treatment option. Here, we report 2 cases of a phenomenon rarely described in published literature, IAF after gastrectomy for ga...

This report describes an 18-year-old woman presenting with abdominal distension, left flank pain, and hypertension. She had a huge abdominal mass, diagnosed as a mesenteric desmoid-type fibromatosis, causing compression of the left external iliac vessels and ureter, as well as elevated renin concentration and hypertension. After surgical removal of the mass, all signs improved including hyperte...

Desmoid tumours are rare mesenchymal tumours, often locally invasive and characteristically associated with a high local recurrence rate after resection. A potential aetiological role for female hormones is indicated. Pregnancy-associated desmoid tumours are almost exclusively located in the abdominal wall. An essential issue is how to counsel women who have had a pregnancy-associated desmoid t...

Peritonitis is a very rare complication of mesenteric fibromatosis. A case is reported which occurred 6 days post-partum. It is suggested that such lesions are hormone-sensitive.
