title: Laugier Hunziker syndrome.
abstract: Laugier Hunziker syndrome is a rare disorder that is characterized by adult-onset hyperpigmented macules of the lips, oral cavity, and fingertips. Longitudinal melanonychia is present in the majority of cases. We present a 45-year-old woman with adult-onset hyperpigmented macules of the oral cavity as well as linear melanonychia that involved multiple fingernails. The history, clinical examination, and paucity of laboratory abnormalities or systemic findings support a diagnosis of Laugier Hunziker syndrome.
