    Area of Science:

    • Dermatology
    • Immunology

    Background:

    • Erythema multiforme (EM) is a self-limiting or episodic mucocutaneous illness.
    • EM minor is typically associated with recurrent herpes simplex virus (HSV) infections.
    • EM major is a more severe form, often linked to drugs or Mycoplasma pneumoniae.

    Purpose of the Study:

    • To outline diagnostic criteria for erythema multiforme.
    • To differentiate between EM minor and EM major.
    • To provide therapeutic guidelines for both forms of erythema multiforme.

    Main Methods:

    • Morphological and histological examination of skin lesions.
    • Clinical association with precipitating factors like infections and drugs.
    • Evaluation of treatment outcomes.

    Main Results:

    • EM minor presents with classic skin lesions, often with oral erosions, linked to HSV.
    • EM major involves atypical skin lesions and mucosal erosions, associated with drugs and Mycoplasma.
    • Treatment strategies vary based on disease severity and etiology.

    Conclusions:

    • Accurate diagnosis of erythema multiforme relies on compatible morphology and histology.
    • Distinguishing between EM minor and EM major is crucial for appropriate management.
    • Therapeutic approaches include symptomatic care, antibiotics for secondary infections, and careful consideration of systemic steroids, especially in EM major.
