Laugier-Hunziker Syndrome

Laugier-Hunziker Syndrome (LHS) was first recognized in the year 1970, and was depicted as acquired hyperpigmented macules of the lips and buccal mucosa mostly linked with longitudinal melanonychia of the nails. A rare benign condition, the syndrome is apparently characterized by macular pigmentation of the genitalia. It needs to be included in the differential diagnosis of diffused oral pigmentation in order to eliminate other conditions having systemic repercussions. There are no core systemic abnormalities or malignant disposition linked with Laugier-Hunziker. Owing to lack of somatic abnormalities, some authorities have proposed to change the name to Laugier and Hunziker pigmentation. In the event of presence of non-classic body location with atypical features, ‘Idiopathic Lenticular Mucocutaneous hyperpigmentation’ is the term which is used.
