Erythema multiforme refers to a category of hypersensitivity disorders. Adults between the ages of 20 and 40 are affected. It’s often noticeable as symmetrical red, patchy lesions on the arms and legs. The precise cause of this disease is unknown, but it has been discovered that it is linked to the herpes simplex virus. This could mean that the virus has started an immunologic phase.
Medications including nonsteroidal anti-inflammatory drugs, anticonvulsants, antibiotics, and sulfonamides are responsible for around half of the cases. Mycoplasma pneumonia and other viral agents have been linked to a few cases. When compared to three skin conditions with identical signs, it is the mildest of reactions. Stevens-Johnson syndrome and toxic epidermal necrolysis, the most extreme type, are the other two reactions (TEN).
