#2172 Well-Differentiated Neuroendocrine Lesions in Inflammatory Bowel Disease

Introduction: Whether inflammatory Bowel disease (IBD) increases the risk of developing neuroendocrine tumors (NETs) is not clear. NETs are rare in IBD, though one recent report suggests that NETs are 15 times more frequent in patients with Crohn’s disease. Besides NETs, which are discrete mass-forming lesions, microscopic neuroendocrine cell clusters or micronests (NEMs), difficult to measure, are sometimes observed in the lamina propria/muscularis mucosae of IBD patients.
