Lichen nitidus is a relatively rare, chronic skin eruption. Lichen nitidus may affect anyone, but typically develops in children and young adults. Lichen nitidus is a benign disease with no associated mortality or complications. The cause of lichen nitidus is unknown. It consists of tiny, skin-colored bumps (papules) that often appear in clusters on the surface of your skin, especially on the arms and legs. Even without treatment, lichen nitidus usually disappears over time. The length of time needed for remission is variable and will depend on the patient and the amount of skin surface involved. If treatment is desired some of the therapies include topical and/or systemic corticosteroids, ultraviolet light therapy, topical or oral retinoids and others but again generally no treatment is needed.
Pathology
The histology of lichen nitidus is significant for a "...localized granulomatous lymphohistiocytic infiltrate in an expanded dermal papilla with thinning of overlying epidermis and downward extension of the rete ridges at the lateral margin of the infiltrate, producing a typical 'claw clutching a ball' picture
