Clinical cases

Lichen nitidus is a rare condition occurring in children and young adults. Clinically it is characterized by the presence of numerous micropapules, usually asymptomatic, localized on the upper limbs, thorax, abdomen or genital area. Different clinical forms of lichen nitidus were described: confluent, vesicular, hemorrhagic, perforating, linear and generalized.

We present the case of a 28 years old male patient diagnosed with generalized lichen nitidus. The lesions, slightly pruritic, were disseminated on the upper and lower limbs, trunk and genital area. Palms, plants, mucosa and appendages were not affected. Histopathology revealed a dense nodular infiltrate located in the papillary dermis with "ball and claw" appearance. Treatment with systemic corticosteroids, antihistamines and topical corticosteroid led to the disappearance of lesions.
