Unusual Bridge-Shaped Hyperplastic Polyp in the Sigmoid Colon.

Abstract

We present a rare morphological variant of a colonic polyp observed during a routine screening colonoscopy. A 62-year-old male with known chronic obstructive pulmonary disease (COPD) and benign prostatic hyperplasia (BPH) was found to have a bridge-shaped polyp in the sigmoid colon. The polyp was successfully resected via snare polypectomy following submucosal adrenaline injection. Histopathological analysis revealed the lesion to be a hyperplastic polyp. To our knowledge, bridge- or horseshoe-shaped hyperplastic polyps have not been previously reported in the literature.
