Pigmented nevi of the oral mucosa: a clinicopathologic study of 32 new cases and review of 75 cases from the literature. Part I. A clinicopathologic study of 32 new cases.

Pigmented nevi are much less common in the oral cavity than they are in the skin. The present study adds thirty-two new cases to the literature. The most common type of nevus was found to be the intramucosal, followed in decreasing order by the common blue nevus, compound nevus, and junctional nevus. The clinical and histologic features of the nevi are analyzed and discussed.
