Eczema herpeticum (EH), also known as varicelliform eruption of Kaposi, is a herpes simplex virus infection that develops mainly in the setting of pre-existing chronic dermatoses such as atomic dermatitis, ichthyosis, seborrheic dermatitis, Darier`s disease, pemphigus foliaceus, mycosis fungoides, and psoriasis, and is most commonly associated with atopic dermatitis.
In this article, we describe an 18-year-old female patient with atopic dermatitis diagnosed with EH after subcutaneous allergen immunotherapy for allergic rhinitis and present this very rare side effect in the light of the current literature.
