Intramucosal nevus in the oral cavity.

AIM: The aim of this study is to report a clinical case of oral nevus. BACKGROUND: Nevus is a congenital or acquired benign neoplasia that can be observed in the skin or mucous membranes. It is an uncommon condition in the oral mucosa. When it does occur, the preferred location is on the palate, followed by the cheek mucosa, lip and tongue. CASE REPORT: In this case study, we relate the diagnosis and treatment of a 23-year-old female patient with an irregular, pigmented lesion of the oral mucosa that underwent excisional biopsy resulting in a diagnosis of intramucosal nevus. CONCLUSION: Nevus can appear in the oral mucosa and should be removed. CLINICAL SIGNIFICANCE: It is important for dental professionals to adequately categorize and treat pigmented lesions in the mouth.
