Skin lesions appeared during the first sunny spring days (average UV index was 5 ‒ moderate). He has no previous history of sun sensitivity. In personal history, five weeks before admission to our department, he started treatment for UC. Treatment included oral and rectal forms of mesalamine alongside oral prednisolone and esomeprazole.</p><elsevierMultimedia ident="fig0005"></elsevierMultimedia><elsevierMultimedia ident="fig0010"></elsevierMultimedia><p id="par0015" class="elsevierStylePara elsevierViewall">At admission routine laboratory analysis of blood and urine were within normal limits.

HIV antigen/antibody, HBsAg, and anti-HCV were all negative. VDRL was negative. Lupus bend tests from sun-exposed and sun-protected areas were negative.</p><p id="par0020" class="elsevierStylePara elsevierViewall">We suggested sun protection along with sun avoidance and initiated topical corticosteroid preparations with concomitant UC treatment (mesalamine 3 g/day, prednisolone 20 mg/day and esomeprazole 20 mg BID) for 4 days. The suggested treatment was without result, erythema was persistent. Due to suspicion that sun sensitivity was induced by mesalamine, mesalamine and topical corticosteroid treatment were discontinued and 20 mg of prednisolone alongside esomeprazole and sun protection remain the only treatment. During the following 4 days, he spent up to 1 hour/day in the sun and despite that, there was a complete regression of skin lesions (<a class="elsevierStyleCrossRefs" href="#fig0005">Figs. 1 and 2</a>).</p><p id="par0025" class="elsevierStylePara elsevierViewall">We were interested on whether photosensitivity appears again in the absence of mesalamine so, we suggested unlimited sun exposure without sun protection, for the next 6 days (10 days in total without mesalamine). During those days were no signs of photosensitivity, but UC worsened and mesalamine re-challenge was approached. He took the first, reintroduced, dose of mesalamine and 12‒15 h later, he spent 30 minutes outside on a sunny morning. During those 30 minutes, erythema reappeared on sun-exposed areas. We established the diagnosis of mesalamine-induced photosensitivity (<a class="elsevierStyleCrossRefs" href="#fig0005">Figs. 1 and 2</a>). The gastroenterologist substituted mesalamine with azathioprine and prednisolone was tapered and stopped.
