Massive desmoid tumor

Case contributed by Dr Michael P Hartung


History of prophylactic total colectomy 3 years ago, with new abdominal mass.

Patient Data

Age: 20
Gender: Male

Very large, relatively well-circumscribed mass filling the abdominal cavity. Bilateral ureteral obstruction due the mass (likely compressive). Total colectomy. 

Case Discussion

Desmoid tumor was pathologically proven and the mass surgically removed. 

Patients with familial adenomatous polyposis (FAP) are at increased risk of desmoid tumors, particularly after surgery (most commonly for prophylactic total colectomy). It is an important cause of morbidity and mortality in this patient group. In this case, the tumor was detected three years after surgery.
