[Lichen nitidus. Report of two cases, one of them with a generalized distribution].

Lichen nitidus is a dermatosis of unknown origin, characterized by the presence of shiny, pinpoint, skin-colored papules that may be asymptomatic or slightly pruriginous. They usually affect forearms, abdomen, buttocks and genitals. We report two cases, one of them with a generalized presentation. Both were treated with topical steroids with good results. A review of this pathology and its therapeutic options is held.
