Eruptive melanocytic nevi (EMN) are rare multiple melanocytic lesions that rare and associated with dermatological and systemic diseases. Drug induced EMN is also reported with the use of biological or nonbiological chemotherapeutics, immunosuppressive agents, and melanocyte stimulators. In recent years, the increasing use of biological drugs resulted in an increased reports of EMN induced by these drugs. The objective of this is reporting EMN in a patient receiving etanercept treatment.
