Laugier-Hunziker syndrome (LHS) is a sporadic, acquired, and infrequent condition characterized by the onset of brown macules on the lips, the oral mucosa, and the acral glabrous skin (mainly fingers and toes) in middle-aged patients. In several cases melanonychia of fingernails and toenails coexists. No other systemic involvement is observed. A case of LHS in a 50-year-old woman is described, with particular attention to dermoscopic features. No dermoscopic specific findings of mucosal/cutaneous maculae have been to date described in the literature. Accumulation of dermoscopic observations of pigmented lesions in LHS is needed and if found to be distinct, it may contribute to a more accurate diagnosis in the future.

Abstract
Laugier-Hunziker syndrome (LHS) is a sporadic, acquired, and infrequent condition characterized by the onset of brown macules on the lips, the oral mucosa, and the acral glabrous skin (mainly fingers and toes) in middle-aged patients. In several cases melanonychia of fingernails and toenails coexists. No other systemic involvement is observed. A case of LHS in a 50-year-old woman is described, with particular attention to dermoscopic features. No dermoscopic specific findings of mucosal/cutaneous maculae have been to date described in the literature. Accumulation of dermoscopic observations of pigmented lesions in LHS is needed and if found to be distinct, it may contribute to a more accurate diagnosis in the future.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
