Laugier-Hunziker syndrome: a case and dermoscopic features.

Area of Science:

• Dermatology
• Medical Case Reports

Background:

• Laugier-Hunziker syndrome (LHS) is an infrequent, acquired condition.
• It presents with characteristic brown macules on the lips, oral mucosa, and acral skin.
• Melanonychia of nails can coexist, with no other systemic involvement.

Observation:

• A case of LHS in a 50-year-old woman is detailed.
• Particular attention is given to the dermoscopic features observed in this patient.
• Current literature lacks specific dermoscopic findings for LHS mucosal/cutaneous maculae.

Findings:

• The case contributes to the limited body of knowledge on LHS.
• Dermoscopic examination was performed on the pigmented lesions.
• No pathognomonic dermoscopic features for LHS maculae are established.

Implications:

• Further accumulation of dermoscopic observations in LHS cases is crucial.
• Distinct dermoscopic findings could enhance diagnostic accuracy for LHS.
• This research underscores the importance of detailed case reporting in rare dermatological conditions.
