A Case of Laugier-Hunziker Syndrome / 대한피부과학회지

ABSTRACT

Laugier-Hunziker syndrome (LHS) is a rare acquired benign macular hyperpigmentation of the lips and oral mucosa which is often associated with longitudinal melanonychia. LHS is known to be an entirely benign condition with no systemic manifestations, which requires patient reassurance as the only intervention. The significance of this condition is due to its inclusion in differential diagnoses of pigmentary disorders of the oral mucosa, especially Peutz-Jeghers syndrome. We report a case of Laugier-Hunziker syndrome in a 66-year-old woman who presented with longitudinal pigmented bands on her fingernails and multiple, pigmented macules on the lip and tongue.
