There is no risk of development of oral malignancies or malignant melanoma. However, it is important that Laugier-Hunziker-Baran syndrome is diagnosed correctly to rule out other differential diagnoses (i.e. Peutz-Jeghers syndrome, Addison disease, and Albright syndrome).<BR>A 69-year-old man presented with multiple pigmented spots of the mouth and lips; these spots appeared 3 yearspreviously.<BR>His right fingers had brownish spots 2-3 mm in diameter. Similar spots were present on the buccal mucosa, lips, palate, and gingiva.<BR>The patient had no history of gastrointestinal disorders or generalized skin disorders. A biopsy specimen takenfrom a site of the lower lip with melanotic pigmentation showed increased pigmentation of the basal cell layer ofthe epithelium. No malignant features were noted in the specimen.
