Three Cases of Generalized Lichen Nitidus

Lichen nitidus(LN) is an uncommon chronic inflammatory disease of shiny, flat-topped, flesh-colored uniform papules most commonly located on the penis, forearms and wrists, lower abdomen, and thighs. LN almost has localized distribution, but in rare cases, it may become generalized. In Korea, three cases of generalized LN were reported.

We report here three cases of generalized lichen nitidus in 31-year-old man, 8-year-old boy, and 6-year-old girl who had generalized numerous pinhead-sized, erythematous to flesh-colored, shiny papules. Microscopically, they had typical appearance of LN.
