title: Laugier-Hunziker syndrome: A case report and review of the literature.
abstract: Laugier-Hunziker syndrome (LHS) is a rare acquired disorder characterized by diffuse macular hyperpigmentation of the oral mucosa and, at times, longitudinal melanonychia. Although LHS is considered a benign disease with no systemic manifestations or malignant potential, it is important to rule out other mucocutaneous pigmentary disorders that do require medical management. Prompt clinical recognition also averts the need for excessive and invasive procedures and treatments. To date, only four cases have been reported in the United States. We present a 77-year-old man who had clinical features typical of LHS and we then provide a review of the literature on LHS and its mimickers.
