Abstract
The presence of invasive cancer is observed in up to 9% of polyps removed at colonoscopy. Certain histopathological features of the tumor are utilized to determine if further treatment is necessary. We present a case of an asymptomatic 70 year old woman with a mesenteric recurrence 10 years following endoscopic polypectomy of a cancer within a pedunculated sigmoid colon polyp. Her initial tumor did not display any of the adverse pathologic features which might have prompted a colectomy. The patient's subsequent endoscopic surveillance did not reveal further mucosal abnormalities. Her recurrence was discovered during the work-up of an isolated elevated CEA level. Here we review current surveillance strategies for follow-up of colorectal adenocarcinoma, as well as the histopathological features of a cancerous polyp which would prompt colectomy. This is the first case of late mesenteric recurrence following endoscopic polypectomy of a cancerous polyp.
