Also known as Erythema Polymorphe
Erythema multiforme is a skin condition of unknown cause, possibly mediated by deposition of immune complex (mostly IgM) in the superficial microvasculature of the skin and oral mucous membrane that usually follows an infection or drug exposure. It is a common disorder, with peak incidence in the second and third decades of life.Source: Wikipedia
Within all the people who go to their doctor with erythema multiforme, 92% report having skin rash, 67% report having fever, and 44% report having itching of skin. The symptoms that are highly suggestive of erythema multiforme are skin rash, itching of skin, mouth ulcer, and skin pain, although you may still have erythema multiforme without those symptoms.
