Lichen nitidus ferskynt typysk by bern en jonge folwoeksenen, en beynfloedet beide seksen en alle rassen gelyk. It toant as lytse, glânzjende, flakke papules op 'e hûd, meastentiids 1 oant 2 mm breed. Dizze papules ferskine faak op 'e earms, skonken, búk, boarst of penile shaft. It is meastentiids asymptomatysk, dus behanneling is oer it generaal foar symptomatyske of kosmetysk fersteurende lesions.
Lichen nitidus most commonly presents in children and young adults and does not favor one sex or race. Lichen nitidus presents as multiple, discrete, shiny, flat-topped, pale to skin-colored papules, 1 to 2 mm in diameter. These lesions commonly present on the limbs, abdomen, chest, and penile shaft. It is usually asymptomatic, so treatment is generally for symptomatic or cosmetically disturbing lesions.
