Characterization of Oral Melanocytic Nevi in Sun‐Exposed and Sun‐Protected Regions

Oral Diseases, Volume 31, Issue 10, Page 2906-2913, October 2025.
ABSTRACT Objective Oral melanocytic nevi (OMN) are histologically similar to skin nevi; however, they are much rarer and not always related to sun exposure. This study aimed to characterize the histopathological, immunohistochemical, and molecular features of OMN in sun‐exposed (vermilion lip) and sun‐protected (intraoral) regions.
