title: An intraoral combined blue naevus.
abstract: A combined blue naevus is described which lay below the epithelial surface of the attached lingual gingiva and the anterior region of the floor of the mouth. There was no visible pigmentation due to the masking effect of the overlying hyperkeratotic mucosa. Histologically the lesion was composed of a mixture of intramucosal naevus cells and dendritic melanocytes typical of a common blue naevus. Prophylactic excision of intraoral naevi is advised.
