What is Erythema Multiforme?
Erythema multiforme is a skin disorder that manifests as red, raised, and sometimes blistered lesions on the skin. The term "erythema" refers to redness, and "multiforme" indicates the variety of shapes and sizes the lesions can take. These lesions can appear on various parts of the body, including the hands, feet, and mucous membranes.
The causes of erythema multiforme are diverse, but they are typically associated with infections, such as herpes simplex virus (HSV), or adverse reactions to medications. In some cases, it can also be triggered by allergies, vaccinations, or underlying medical conditions. The exact cause may vary from person to person.
Why Does Erythema Multiforme Occur?
Erythema multiforme occurs as a result of the body's immune response to a specific trigger, typically an infection or medication. The immune system recognizes the trigger as foreign or harmful and mounts an immune response against it. This immune response can lead to the characteristic skin lesions associated with erythema multiforme.
Common triggers for erythema multiforme include:
- Infections: In many cases, the condition is triggered by infections, with the herpes simplex virus (HSV) being a common culprit. Other infectious agents, such as Mycoplasma pneumoniae and the Epstein-Barr virus, can also be triggers.
- Medications: Certain medications, especially antibiotics like sulfonamides, penicillins, and nonsteroidal anti-inflammatory drugs (NSAIDs), can induce erythema multiforme as an adverse reaction.
- Allergies: Allergic reactions to substances like foods, insect stings, or contact allergens can occasionally trigger erythema multiforme.
- Vaccinations: Some individuals may develop erythema multiforme following vaccinations.
