Abstract
We report a case of inflammatory fibroid polyp (IFP) of the transverse colon. A woman in her late 40s had a check-up at our hospital for melena. Colonoscopic examination revealed a polyp of Isp type in the transverse colon. Barium enema study demonstrated a 3-cm tumor in the transverse colon. Preoperative diagnosis was colon cancer invading to the submucosal layer. We performed a left hemicolectomy by laparoscopically assisted surgery. A diagnosis of inflammatory fibroid polyp was made based on the histological features consisting of proliferating fibrous connective tissue and small blood vessels, with inflammatory cell infiltration.
IFP of the colon is rare. The 21 cases reported in Japan, including our case, are reviewed.
