What is Erythema Multiforme?

Erythema multiforme is a common skin disorder that usually affects children and young adults. The rash usually presents itself in red welts, but it sometimes can appear purple or blistered. Though doctors are unsure why people get erythema multiforme, there are theories that it is caused by an immune complex in the skin or mucous membranes or the herpes virus.

Identification

• Erythema multiforme is a common syndrome that usually affects people in their twenties and thirties. Men are more likely to have erythema multiforme, and one-third of people who get it suffer a recurrence.

Types

• Erythema multiforme has been divided into two different sub-categories: erythema multiforme and Stevens Johnson syndrome. Each has its own unique sets of symptoms.

Erythema Multiforme Minor

• Erythema multiforme minor affects 80% of the people with this disease. The rash appears mainly on the backs of hands and feet with some minor itching and burning. Erythema multiforme minor usually resolves itself in one to two weeks.

Stevens Johnson Syndrome

• Stevens Johnson syndrome is a much more serious variance of the disease that results in death 5 to 15 percent of the time. Along with the rash, the patient develops large blood blisters. The lips and eyes are often severely affected, and internal organs are sometimes involved.

Treatment

• While treatment is usually not necessary for Erythema multiforme minor, drugs such as Zovirax or Valtrex are sometimes prescribed. For sufferers of Stevens Johnson syndrome, therapeutic measures--such as those used in burn units--are implemented.
