ABSTRACT

Laugier-Hunziker syndrome is an idiopathic, macular hyperpigmentation of the oral mucous membranes and the lips, with frequent pigmentation of the nails in a longitudinal pattern. Laugier-Hunziker syndrome is a rare disease with approximately 100 cases reported in the literature. The clinical features consist of dark brown to bluish-black macules mainly located on the buccal mucosa and lips. Involvement of the tongue is exceedingly rare. Herein we report a 25-year-old woman diagnosed as Laugier-Hunziker syndrome, with confluent, hyperpigmented lesions of the tongue, that responded to cryosurgery.
