Erythema Multiforme, or EM, is a rare skin disorder characterized by skin lesions that look like a bullseye. It is an acute and sometimes reoccurring condition that can be caused by a variety of triggers including sensitivity to medications or infection. The disorder has two categories: Erythema Multiforme Minor and Erythema Multiforme Major. Keep reading to learn more, including symptoms, causes, and treatments.

1. Erythema Multiforme Minor

Erythema Multiforme Minor, or EM Minor, is considered to be a mild form of EM. It occurs when your body has a sensitivity to medication or infection. This trigger, in turn, causes the skin and mucous membranes to react, making the bullseye rash appear. The rash itself will be bright red around the outer edges and have a white bump in the center. Outbreaks generally start on the legs and arms and spread towards the center of the body.
