[A rare tumor: desmoid of the musculus rectus abdominis. Apropos a clinical case]

The authors report a case of left abdominal rectum muscle desmoid tumor which has been surgically treated. After some considerations of the particular pathogenetic, anatomopathological and clinical characteristics of this neoplasm, they state that a precise preoperative diagnosis is always difficult, in spite of modern diagnostic means. They conclude that, nowadays, surgical extirpation is the most reliable therapeutical method, although it is burdened by a consistent incidence of local recidives (over 30%).
