    Here, we’ll take a look at erythema multiforme. As we walk through this, you’ve heard of the term erythema quite a bit, and it would be in your best interest to, every once in a while, just come back and make sure that you’re extremely aware of some of the important erythemas that you must know for your boards and wards.

However, you'll notice this and you’re definitely worried about, maybe perhaps, major. Another name for erythema multiforme, EM major, is Stevens-Johnson syndrome. Oh, boy.
