Lichen nitidus, lichenoid


Lichen nitidus (LN) is a benign micropapular eruption of unknown etiology that often follows an unpredictable course. LN typically affects children and young adults and presents with asymptomatic, discrete, uniform, skin colored, pin-point sized papules.1 These papules are commonly found on the chest, abdomen, flexor surfaces of the upper extremities, dorsal hand, and anogenital region.1 Focal presentation is more common while generalized distribution of LN is rarer and seen more exclusively in pediatric patients.2 Although patients are typically asymptomatic, pruritus is sometimes a noted symptom.1 We report the diagnosis and treatment of an uncommon case of generalized LN in a middle-aged adult.
