Core Tip

Core tip: We report a 59-year-old man presenting with blood and mucus in the feces, diarrhea and constipation. A subsequent endoscopy of the rectum revealed a 5-cm ulcerative nodule in the anterior wall of the rectum, 5 cm from the anal verge. Abdominal magnetic resonance imagining revealed thickening of the mucosa-submucosa, raising suspicion of rectal carcinoma. The surgical resection of the rectum was performed. However, the final pathology suggested an unusual case of solitary rectal ulcer syndrome complicating sessile serrated adenoma/polyp.
