Crohn's Disease Associated with Giant Inflammatory Polyposis

Summary

We found shallow serpiginous, longitudinal ulcerations in the descending colon at the first examination of a 17-year-old female patient with Crohn's disease. Four months later at the second examination, we observed that a polypoid lesion had formed longitudinally in the region of the healed ulcers. The third examination, one year later, showed the presence of pedunculated and semi-pedunculated giant polyps in the descending colon. The lesion of the descending colon was removed surgically to cure the crampy abdominal pain caused by colonic obstruction. The segmental colectomy specimen showed longitudinally aligned pedunculated polyps of various sizes. The pathological diagnosis was inflammatory polyposis. To the best of our knowledge, there have been very few reports on the appearance of a number of pedunculated polyps such as in this case.

This reports shows, through endoscopic pictures, the evolution of the polyp and discusses its formation.
