Intramucosal nevus as a lesion on the lip: A case report

Abstract

Oral melanocytic nevi are benign proliferation of nevus cells in the epithelial layer, the submucosal layer, or both. They are classified as junctional, intramucosal, and compound nevi. They may also be classified as congenital or acquired. Unlike their cutaneous counterparts, oral melanocytic nevi are rare. Intramucosal nevi are typically light brown and dome-shaped, and are the most common type, accounting for 64% of all reported oral nevi. The common blue nevus is the second most common type found in the oral cavity, accounting for 16.5–36% of all oral nevi. In this article, we report a case of an intramucosal nevus in a male patient on the right corner of the lower lip, which presented as a mucocele and was histopathologically confirmed.
