Synopsis

An oral melanotic macule is a benign hyperpigmentation of the mucous membranes occurring in approximately 3% of the general population. There is an increase in focal melanin deposition without an increase in the number of melanocytes. Melanotic macules are most commonly found on the vermillion border of the lip, lower more often than upper. Lesions can also be found on the gingiva or palate, and they may be multiple. Although benign, biopsy may be needed to rule out a diagnosis of melanoma. Oral melanotic macule is common in patients of color and is seen more frequently in women than men. Average age at time of presentation to the physician is at approximately 40 years, though these macules may appear at any age. In patients of darker skin types, onset typically occurs in adolescence. Some experts prefer to refer to lesions on the lip as "labial melanotic macules," although histopathology is identical to that at any other mucosal site.
