Ulcerative colitis may be associated with a number of skin lesions such as erythema nodosum and pyoderma gangrenosum. We here describe an unusual case of a 33-year-old-caucasian male with ulcerative colitis and skin lesions diagnosed as leukocytoclastic vasculitis. An initial treatment with oral deflazacort led to little benefit, while treatment with oral mesalazine caused remission of the skin and intestinal manifestations in 2 weeks.
