Laugier-Hunziker syndrome: a rare case report and review of the literature

Laugier-Hunziker syndrome is a rare, hereditary pigmentary disorder characterized by mucocutaneous lentiginous lesions and melanonychia. The condition is regarded as benign since underlying malignancies or systemic disorders were not reported. Since various malignancy syndromes including Peutz-Jeghers and Cronkhite-Canada syndrome and systemic cause of hyperpigmentation such as Addison disease and drugs are presented with similar mucocutaneous findings, it is of paramount importance to assess the patients to exclude aforementioned conditions.
