Desmoid tumor

A desmoid tumor, also known as aggressive fibromatosis, is a rare, monoclonal fibroblastic proliferation arising from deep connective tissues such as fascia and musculoaponeurotic structures

A desmoid tumor, also known as aggressive fibromatosis, is a rare, monoclonal fibroblastic proliferation arising from deep connective tissues such as fascia and musculoaponeurotic structures It most commonly develops in young to middle-aged adults, appearing as abdominal wall, intra-abdominal, or extra-abdominal lesions in the limbs, chest wall, or head and neck

It most commonly develops in young to middle-aged adults, appearing as abdominal wall, intra-abdominal, or extra-abdominal lesions in the limbs, chest wall, or head and neck Although desmoid tumors lack metastatic potential, they exhibit an unpredictable clinical course characterized by infiltrative local invasion into adjacent organs, nerves, and vessels, often resulting in significant pain, functional impairment, and high rates of local recurrence

Pathophysiologically, these neoplasms are driven by aberrant Wnt/beta-catenin signaling, typically stemming from somatic mutations in the *CTNNB1* gene or, less frequently, germline mutations in the *APC* gene associated with familial adenomatous polyposis
