Atypical Distribution of Inflammation in Newly Diagnosed Ulcerative Colitis is not Rare

Abstract

Patchy⁄segmental skip lesions and rectal sparing occur not infrequently in adult patients with newly diagnosed, untreated UC. As such, these features alone should not be considered to be definitive evidence against a diagnosis of UC. There does not appear to be a prognostic implication of an atypical distribution of lesions.
