Blue-black macule on the maxillary palate.

A cellular blue nevus located on the palate of a 72-year-old female is reported. This intraoral finding is uncommon and should be distinguished from clinical entities it closely resembles. Practitioners should be aware that a pigmented palatal lesion in fact may be a malignant melanoma. Surgical excision with microscopic examination is the only means by which an accurate diagnosis can be made.
