Pyogenic granuloma (PG) generally appears in the skin or oral cavity, but rarely occurs in the small intestine, where it can cause bleeding. To date, only 35 cases of small intestinal PG have been reported in the English literature. We retrospectively collected information from the clinical records of seven cases of small intestinal PG that were managed in our hospital and summarized the characteristics. Further information on the clinical characteristics was obtained from the literature. Capsule endoscopy, useful for identifying the source of hemorrhage in obscure gastrointestinal bleeding, can detect PGs. Treatment can often be accomplished with endoscopic mucosal resection.
