Lichen nitidus is a chronic inflammatory disease of unknown cause characterized by 1–2 mm, discrete and uniform, shiny, flat-topped, pale flesh-colored or reddish-brown papules that may appear as hypopigmented against dark skin. Occasionally, minimal scaling is present or can be induced by rubbing the surface of the papules. The disease usually affects children and young adults and is painless and usually nonpruritic, although protracted itching may occur in some cases.
Lichen nitidus 通常出现在儿童和年轻人中,对性别和种族均无差异。它表现为皮肤上出现光泽的小平顶结节,直径通常为 1 至 2 毫米。这些结节常见于手臂、腿、腹部、胸部或阴部。该病通常无症状,治疗仅针对有症状或影响美观的病灶。 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.
