Abstract
Eruptive disseminated Spitz nevi (EDSNs) are clinically rare, but no malignant change has been reported. Most EDSNs remain stable, which affects their appearance and causes great psychological pressure on patients. We report the case of an 18-year-old man who suddenly developed a large number of pigmented nevi within 20 days. After a two-year follow-up, most of the nevi spontaneously resolved without any treatment.
