Desmoid Tumour

Pathophysiology: Desmoid tumors are cytologically bland fibrous neoplasms originating from the musculoaponeurotic structures throughout the body. Desmoid tumors often appear as infiltrative, usually well-differentiated, firm overgrowths of fibrous tissue, and they are locally aggressive. The synonym aggressive fibromatosis describes the marked cellularity and aggressive local behavior.

Treatment: The primary treatment for desmoid tumor is primary surgery with negative surgical margins. In those patients who refuse surgery or are not surgical candidates, the treatment used is radiation therapy. Pharmacologic therapy with antiestrogens and prostaglandin inhibitors may also be used.

Major research: Stromal signatures in endometrioid endometrial carcinomas: The pattern of myometrial invasion in endometrioid endometrial carcinomas varies considerably; ie, from widely scattered glands and cell nests, often associated with a fibromyxoid stromal reaction (desmoplasia) and/or a lymphocytic infiltrate, to invasive glands with little or no stromal response.
