Erythema multiforme (/ɪˌrɪθiːmə mʌltɪˈfɔːrmiː/; EM) is a skin condition of unknown etymology that presents as a rash. It is considered to be a type of hypersensitivity reaction and is often triggered by infections, medications, or other triggers.

Erythema multiforme is characterized by the rapid onset of skin lesions that may appear anywhere on the body. The lesions often have a distinctive "target" appearance, with a red ring around a pale center.
Causes
The exact cause of erythema multiforme is unknown, but it is often associated with a reaction to an infection or medication. Common triggers include the herpes simplex virus, mycoplasma pneumoniae infection, and certain medications such as sulfa drugs, penicillins, and barbiturates.
Symptoms
Symptoms of erythema multiforme can vary but often include red, itchy patches or hives; a rash that may appear as target-shaped lesions or circular, red patches; and blisters or ulcers in severe cases. Other symptoms may include fever, general ill feeling, joint aches, and eye irritation or soreness.
Treatment
Treatment for erythema multiforme primarily involves addressing the underlying cause, if known, and managing symptoms. This may include discontinuing any triggering medications, treating any underlying infections, and using medications to relieve symptoms such as itching and pain.
