Lichen Nitidus

Excerpt

Lichen nitidus is a rare chronic inflammatory condition first described in 1907 by Pinkus. This uncommon cutaneous eruption has clearly defined clinical and histopathological characteristics with an unknown etiology and pathogenesis. It 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.
