What Is Erythema Multiforme?
7. Diagnosis of Erythema Multiforme
A doctor can typically diagnose the affliction with a physical examination. The practitioner analyzes the rash for the characteristics that are indicative of erythema multiforme, such as color, shape, size, and distribution.
The physician may order additional tests to determine if there is an underlying infection causing the condition that needs to be treated. The targeted shape of the lesion can lead to confusion with other causes that exhibit a similar outbreak. Some people mistake the rash for Lyme disease. When it appears in children, there may be a suspicion of child abuse from cigarette burns.
