Description Erythema multiforme...

Description

Erythema multiforme is a type of skin rash that has a characteristic target appearance with round, red borders and central clearing. It can occur as a reaction to certain medications, especially antibiotics such as sulfa drugs, or to infections, such as herpes simplex. The rash usually resolves on its own, but it may recur. Some people have frequent episodes. Erythema multiforme can sometimes be associated with a systemic illness called Stevens-Johnson syndrome.

Symptoms

Symptoms include the abrupt onset of a round red rash with raised borders and central clearing. People with Stevens-Johnson syndrome can become very ill with high fever, mouth sores, red eyes, genital sores and liver injury. The rash can progress to blisters, which may be widespread and painful.
