Colon Obstruction and Gradual Regression of Giant Pseudopolyps in Inflammatory Bowel Disease

Inflammatory pseudopolyps associated with inflammatory bowel disease occur on inflamed colon mucosa due to the regeneration and healing of ulcerated epithelium. They are classified as giant when they are over 1.5-cm in diameter. These are a rare, benign complication, but can be similar in appearance to colorectal cancer. It has been reported that they do not usually regress after medical treatment, requiring endoscopic resection or even surgery. In this paper, we report an unusual case with gradual regression of giant pseudopolyps with medical treatment, in a patient with inflammatory bowel disease, and another very uncommon case of a giant pseudopolyp in indeterminate colitis, with obstruction requiring surgery, as it was not possible to rule out carcinoma. A multidisciplinary team is very important.
