Resumo(s)
A síndrome de Laugier-Hunziker é uma hipermelanose mucocutânea adquirida, idiopática, benigna que afecta lábios e mucosa oral, e/ou outros locais de fegumento cutâneo. Bandas longitudinais hiperpigmentadas nas unhas ocorrem em cerca de 60% dos doentes. Descrevemos o caso de duas doentes com características clínicas de síndrome de Laugier-Hunziker, uma das quais com um quadro clínico clássico, enquanto na outra foi notada pigmentação adicional na vulva e dedos. Estes dois casos clínicos ilustram as variações topográficas da síndrome de Laugier-Hunziker. É feita uma revisão de causas potenciais de pigmentação oral.
The Laugier-Hunziker syndrome is an acquired, idiopathic, benign mucocutaneous hypermelanosis that usually occurs on the lips and oral mucosa, although it may appear at other sites. Nails are frequently involved, in approximately 60% of patients, mainly forming longitudinal hyperpigmented bands. We report two female patients with the clinical features of Laugier-Hunziker syndrome; one of them exhibits the classical features, while in the other were noted additional vulvar and fingers pigmentation. These two observations illustrate the topographical variations of Laugier-Hunziker syndrome. We review potential causes of oral pigmentation.
