Extra-Abdominal Fibromatosis (Desmoid Tumor): A Rare Tumor of the Lower Extremity Arising from the Popliteal Fossa. Mehmet Ali Kaygin,1. Extra-abdominal desmoids are deep-seated, benign (noncancerous) tumors. They are very rare tumors. While desmoid tumors do not spread to other parts of. Extra abdominal desmoid fibromatosis is a complex condition with many recognised treatments including active observation, hormonal therapy, chemotherapy.

Radiation therapy has also shown success in a number of patients, even those with intra-abdominal tumors. The histologic appearance of the tumor is usually consistent in various microscopic fields within a given case as well as from case to case.

Histologic examination of the surgical specimen was consistent with an extra-abdominal desmoid tumor. Extra-abdominal fibromatosis, also known as a desmoid tumor, is a rarely observed lesion of benign biological significance, characterized as a non-metastatic lesion with local fibromztosis 1.

The lesion appeared to be tenuously hypointense in T1-weighted sequences and unevenly hyperintense in T2-weighted sequences, which was not indicative of hematic content, nor pathognomonic of a specific nature Figs.

In our case, the patient had no identifiable risk factors for the development of a desmoid tumor. The relationship of desmoids in FAP to sporadic cases is uncertain in view of the distinctive early histopathology and the observation that APC gene mutations are uncommon in sporadic desmoids.

Extra-abdominal fibromatosis: Clinical and therapeutic considerations based on an illustrative case

Histological examination showed evidence consistent with extra-abdominal fibromatosis. The selection of optimal treatment is not standardized but, when possible, radical and aggressive surgical resection with margins free of disease R0 remains, to date, the preferred treatment for desmoid tumor.

However, this treatment still has a fair rate of local recurrence 5. Different biologic features of desmoid tumors in adult and juvenile patients: Desmoid tumors originate most frequently from abdominal fascial or musculoaponeurotic structures, although they may appear at extra-abdominal sites. Severe and extraabbdominal fatal clinical problems are sometimes caused by these tumors, especially if mesenteric vessels extraabdominnal other abdominal organs are obstructed.

This application of personalized medicine in fibromatosis could lead to the right treatment at the right time for the optimal outcome. This “non-aggressive” protocol was applied on a larger multi-institutional series of patients fibromatsis and its implementation avoided aggressive surgery or radiotherapy on the majority of primary tumours.

Extra-abdominal fibromatosis: Clinical and therapeutic considerations based on an illustrative case

Generally, desmoid tumors present as a mass of hard consistency that is not well-defined, and is typically infiltrative and adherent to the surrounding tissue. No evident loss of signal of the lesion in B T1-weighted imaging in opposition phase sequences or C fat-saturated T1-weighted imaging, demonstrating the absence of intracellular and extracellular adipose tissue.

The definitive histological examination showed evidence consistent with extra-abdominal fibromatosis: Fibromatosis [title] desmoid “loattrfree full text”[sb]. Trisomy 20 and 8. If firbomatosis features are typical, the differential diagnosis typically includes extrasbdominal and soft tissue tumors such as fibrosarcomas or neurofibromas.
