The variceliform eruption of Kaposi (EVK) is the cutaneous dissemination of the herpes simplex virus (HSV), the most frequent etiology being HSV type 1. It usually occurs in patients with underlying skin diseases or due to a lesion in the epidermal barrier. Clinical suspicion is confirmed by polymerase chain reaction, virus isolation in culture or by monoclonal antibodies made from a sample of skin lesions. The most frequent complication is bacterial superinfection due to Staphylococcus aureus and the treatment of choice is oral or intravenous acyclovir, depending on the severity.
In literature, there are many articles that associate atopic dermatitis with the EVK. But these two pathologies do not always come hand in hand, so their diagnosis can sometimes be a challenge for the pediatrician.
We present an update on the knowledge of this disease following a case recently diagnosed in our service.

Eczema herpeticum is the cutaneous dissemination of the herpes simplex virus in patients who are carriers of chronic skin conditions, mainly atopic dermatitis or who have a damaged epidermal barrier. It is a more or less serious process that may involve complications, which responds well to treatment and which requires an early diagnosis.
