Laugier-Hunziker syndrome is a rare acquired disorder characterized by diffuse hyperapigmentation of the oral mucosa and longitudinal melanonychia in adults. Laugier-Hunziker syndrome is considered a benign disease with no systemic symptoms nor malignant potential.

Case report
In a 48-year-old women hyperpigmentation developed in the buccal mucosa, lips, labia, nail plates and the skin of fingers and toes. Laugier-Hunziker syndrome was diagnosed on the basis of clinical presentation, dermoscopy, and exclusion of systemic causes of the symptoms.
