Laugier-Hunziker syndrome: case report and review of the literature.

Laugier-Hunziker syndrome is a rare acquired disorder characterized by diffuse pigmented macules of the oral mucosa. Other mucosal and cutaneous surfaces may be affected, and nail involvement is frequent. A case of Laugier-Hunziker syndrome in a Greek female with multiple buccal and labial mucosal lesions and unusual conjunctival involvement is presented here. In addition, a thorough review of the English language literature of this rather under-recognized syndrome is included and the main differential diagnostic possibilities are discussed.
