Erythema multiforme (say "air-uh-THEE-muh mul-tuh-FOR-mee") is a rash that often causes red spots. These spots can look like targets, with a darker area in the center.
In most cases, doctors know the rash when they see it. But sometimes blood tests or testing a tissue sample (biopsy) can confirm what type of rash it is. Or these tests can help rule out other problems.
This skin condition is usually found on the hands, feet, arms, or legs. But it can affect any part of the body. This includes the mouth, the eyes, and the genitals. Sometimes the rash itches or burns. Some children have a fever or feel a little sick.
Doctors don't always know what causes erythema multiforme. But the rash may be related to an infection, a medicine, or another health problem.
In most cases, the rash goes away on its own in a few weeks. In some people, the rash returns. Treatment can include medicines for itching and mouth pain.
