Core Tip

Core tip: In inflammatory bowel disease patients, pseudopolyps are formed at the bowel wall during the inflammatory process. Published reports have begun to elucidate the mechanism of pseudopolyp formation and prevalence; however, the clinical challenge in distinguishing these entities from other dysplastic lesions remains and there is scarce data about their complications and management. In this review, we aimed to condense the published reports about their prevalence and to present a classification of their distinct characteristics based on endoscoping and histologic criteria, in order to facilitate their recognition. Moreover, available methods for confronting their complications and long-term management are presented.
