It can appear in many different locations in the gastrointestinal tract, the most common being the gastric antrum (70%) followed by the small bowel (20%) however it rarely occurs in the esophagus and colon. Inflammatory fibroid polyp (IFP) is a rare benign polypoid lesion of the gastrointestinal tract. These findings are consistent with a histopathological diagnosis of IFP. The spindle cells were positive for CD34 and S100 but negative for c-kit and muscle markers. Proliferation of spindle cells and infiltration of inflammatory cells such as plasma cells and eosinophils were observed. Histologically the polyp was located in the submucosa of the gastrointestinal tract.
After these measures we were able to resect the stalk and the polyp was retrieved. We placed an endoclip at the base of the stalk and then applied argon plasma coagulation at 1.0 l/min and 40 W. However the polyp stalk was extremely difficult to resect despite several attempts with the hot snare. After saline injection, we attempted to remove the polyp with a hot snare. A 12-mm pedunculated polyp was found at the hepatic flexure of the colon. A 74-year-old asymptomatic female underwent a screening colonoscopy in our hospital. We present a rare case of a pedunculated IFP in the hepatic flexure of the colon treated successfully with a combination of argon plasma coagulation, endoclipping and polypectomy. Histologically IFP is characterized by a mixture of numerous small vessels, fibroblasts and edematous connective tissue associated with marked inflammatory infiltration by eosinophils. Most IFPs occur in the stomach and colonic occurrence is very rare.
