Core Tip

Core tip: Distinction between Crohn’s disease and ulcerative colitis or inflammatory bowel disease (IBD) type unclassified can be of pivotal importance for a tailored clinical management, as each entity often involves specific therapeutic strategies and prognosis. Nonetheless, the differential diagnosis is an untangled issue, and the proper diagnosis cannot be reached in up to 10% of patients presenting with colitis. Hence, we address the problem of differential diagnosis in IBD colitis, thereby revising current and emerging diagnostic tools to refine disease classification.
