Lichen nitidus: A case report of generalized form

Lichen nitidus (LN) is a relatively rare chronic inflammatory skin condition of unknown etiology. Here-in we present this is a 28-year-old male patient presented to the outpatient clinic complaining of very itchy persistent skin lesions which have been observed for 6 months. Skin examination revealed multiple widespread, non-scaly, skin colored, tiny papules all over his body including face, neck, chest, back, abdomen and upper parts of all extremities. Hair, nail and mucous membranes were all normal. Skin biopsy was taken from the skin lesion. The epidermis showed mild spongiosis. The dermis showed patchy mononuclear cellular infiltrate in the upper dermis and vacuolar degeneration of the basal layer. Diagnosis of lichen nitidus was made. The patient was treated by topical corticosteroid and narrow-band UVB Phototherapy with excellent response. Our case is unusual in that it is a generalized form of LN with severe pruritus.
