The Silent fibrous Legacy of Familial Adenomatous Polyposis: A Desmoid Tumor Unveiled in the Abdominal Wall

Desmoid tumors are rare fibroblastic proliferations with locally aggressive behavior and no metastatic potential. They are frequently associated with genetic mutations, particularly in the context of familial adenomatous polyposis (FAP). We report the case of a 29-year-old woman operated for colonic adenomatous polyposis in 2018, in whom an abdominal parietal mass revealed a desmoid tumor. We describe the clinical features, diagnostic means, including imaging, and therapeutic options, through a review of the literature.
