“…Dating back to 1817, EM was first recognized by Bateman and Bulkley. Later, Hebra, in 1866 described the morphologic features of the eruption under the term “erythema exsudativum multiforme” [ 1 ] as an acute mucocutaneous hypersensitivity reaction characterized by skin eruptions that causes a variety of skin lesions-hence named ´multiforme´ with or without mucous membrane lesions [ 2 ]. Etiology spectrum is variable which include drugs (NSAIDs, sulphonamides, phenytoin, and carbamazepine), infectious agents and food additives.…”
