Abstract

Chronic inflammation of the intestinal mucosa has been associated with the appearance of inflammatory polyps or pseudopolyps. Among the distinct categories of inflammatory polyps are inflammatory myoglandular polyps (IMGP) usually found in the colorectum. Only one case of IMGP in the terminal ileus has been described since their first description. We report the first case of an inflammatory polyp with both hyperplastic and myoglandular histological characteristics, in the terminal ileum of a patient with quiescent Crohn’s disease, causing recurrent intussusception.
