Oral Melanotic Nevi: a Case Report and Review of Literature

Oral melanotic nevi are uncommon oral lesions causing focal pigmentation. Melanotic nevi are benign melanocytic tumours originating from defective melanoblasts of the neural crest. Clinically, it is an asymptomatic, flat or slightly elevated lesion of brown or brown-black color. It is usually located on the palate and buccal mucosa and rarely on the gingiva and lips. Based on histological criteria, intraorally four types of nevi have been described: the intramucosal, junctional, compound and blue. In this article, we are reporting a case of oral pigmented lesion in a young female with an unusual history of associated occasional pain which was histopathogically diagnosed as intramucosal nevus.
