Description

<p>Case 1 was a 62-year-old male taking mesalazine for ulcerative colitis. Total colonoscopy performed due to hematochezia revealed a 20-mm-sized, slightly elevated lesion in the ascending colon. However, no malignant findings were found, and three months later, the lesion had almost disappeared. Case 2 was an 84-year-old male in his 80s taking mesalazine for ulcerative colitis. Esophagogastroduodenoscopy performed due to melena showed no hemorrhage. Total colonoscopy showed a thick prominent lesion with dense nodules in the ascending colon. However, no malignant findings were found, and three years later, the lesion was considered to have become a scar and scattered inflammatory polyps. These findings may be characteristic endoscopic findings of ulcerative colitis.</p>
