Lichen nitidus (LIE-kun ni-TIE-dus) is a rare skin condition that usually appears as tiny, skin-colored, glistening bumps on the surface of your skin. Lichen nitidus results from abnormal inflammatory activity in skin cells, but the cause of inflammation is unknown.
Although lichen nitidus may affect anyone, it typically develops in children and young adults. Lichen nitidus rarely causes discomfort and usually clears up on its own without treatment.
Lichen nitidus doesn't increase your risk of skin cancer, and it isn't an infectious disease that can spread to other people.
