case_images: Subsequent colonoscopic findings.. 1-a: Active ulcerative colitis, small ulcers, marked erythema, absent vascular pattern, spontaneous bleeding (initial endoscopy).. 1-b: Multiple giant and filiform post-inflammatory polyps (PIPs). Some of them were sessile, others were interconnected crossing the lumen of the colon and forming multiple mucosal bridges. The mucosa had normal vascular pattern in the places, where PIPs were not present. There were no erosions or ulcerations (endoscopy after one year of therapy).. 1-c: Regression of PIPs (last endoscopy).

case_images: The first colonoscopy showed ulcerative, hemorrhagic inflammation of the whole colon (Fig. 1-a). Multiple giant and filiform pseudopolyps were revealed in descending and transverse colon (Fig. 1-b). Subsequent (third) colonoscopy was performed two years after diagnosis and revealed regression of giant PIPs (Fig. 1-c).
