[Childhood eruptive nevi: a case report]

"Eruptive nevi" is a phenomenon characterized by a rapid appearance of multiple melanocytic nevi. It is mainly developed in three groups of patients: those with systemic immunosuppression, bullous cutaneous disorders, and a melanocytic stimulation drug. We report on the case of an 11-year-old boy who was diagnosed with acute lymphoblastic leukemia. A few months after the beginning of the chemotherapy, he developed multiple pigmented lesions over the skin. Eruptive nevi syndrome has been described in the literature in 29 cases in the context of severe bullous disease and in immunosuppression. Nevi most often appear on the trunk and extremities, notably on the feet in the context of immunosuppression. They are localized in areas of bullous lesions in bullous diseases. Due to an increased melanocytic stimulation in eruptive nevi patients, long-term surveillance of individuals who have developed eruptive nevi is required, and increased sun prevention should be suggested.
