RT Journal Article T1 Topical mesalazine as a cause of Stevens-Johnson syndrome. A1 Núñez Ortiz, Andrea A1 Trigo Salado, Claudio A1 de la Cruz Ramírez, María Dolores A1 Herrera Justiniano, José Manuel A1 Leo Carnerero, Eduardo AB Mesalazine is a drug routinely used in ulcerative colitis and usually has few side effects. There have been reports of uncommon cases of severe mucocutaneous damage, such as Stevens-Johnson syndrome (SJS) and toxic epidermal necrolysis (TEN), induced by salicylates. It is important to diagnose these promptly due to the high morbidity and mortality rates. We describe the case of a 46-year-old female with ulcerative proctitis, who developed SJS following topical mesalazine use. The lesions responded well to intravenous corticosteroids after discontinuation of the drug.
