Inflammatory fibroid polyps (IFP) are benign mesenchymal tumors described first by Vanek, who reported a series of cases occurring in the gastric submucosa. Since then, there have been varying presentations of these benign tumors, many of them have shown to infiltrate into surrounding tissue and can cause significant symptoms including intestinal obstruction and intussusception. This can result in peritonitis and bowel necrosis, and can change the management of a typical bowel obstruction. Adult intussusceptions are rare, as this phenomenon occurs most often in infants and children. IFP can occur anywhere in the gastrointestinal tract but most commonly in stomach and small intestine. The largest IFP arising from the gastrointestinal tract described in English literature has been 15 cm at total length. Our case is unique in that it is the largest IFP reported to date occurring in the GI tract.
