Definition

Melanocytic nevi of the oral mucosa are benign tumors of melanocytes, the pigment-producing cells in the skin and juxtacutaneous mucous membranes, including the oral mucosa. Melanocytic nevi are much less common in the oral mucosa than on the skin (Buchner and Hansen 1987; Buchner et al. 2004; Müller 2010). The intramucosal nevus is the oral counterpart of the cutaneous dermal nevus.

In an intramucosal or subepithelial nevus, the (nests of) nevus cells are located within the underlying connective tissue and are often nonpigmented. They are usually small, 4–6 mm in greatest diameter, well-circumscribed macules or slightly raised papules.

Clinical Features

Incidence

Intramucosal nevi are the most common subtype (60–80%) of nevi.

Age

The age ranges from 3 to 87 years with a mean age for intramucosal nevi of 38 years.

Sex

A female preference has been reported (female to male ratio 1.5:1).
