Abstract
OBJECTIVE: The purpose of this study was to evaluate the clinical and histopathologic features of oral melanocytic nevi (OMN).
STUDY DESIGN: One hundred cases of OMN were retrieved from the files of two oral pathology services, and the data were analyzed with regard to histologic type and clinical features.
RESULTS: Intramucosal nevus was the most common type (61%), followed by common blue nevus (23%), compound nevus (7%), and junctional nevus (3%). Combined nevus and cellular blue nevus were rare (2% each). The hard palate was the most commonly affected site (33%), followed by the buccal mucosa (18%), vermilion border of the lip (18%), and gingiva (15%). An interesting case of intramucosal nevus with lipomatosus-like changes and neurotization and two cases of oral dysplastic nevus are also reported.
CONCLUSIONS: Intramucosal and common blue nevi are the most common types of OMN. Dysplastic nevus, which is recognized as a marker for melanoma in the skin, can rarely involve the oral cavity. Accordingly, dentists, especially oral and maxillofacial pathologists, should become familiar with the clinical and histopathologic features of this entity.
