Abstract:
Lichen nitidus is an uncommon, asymptomatic cutaneous eruption. There are many reports of variable subtype of lichen nitidus including of spinous, follicular, vesicular, hemorrhagic, actinic, purpuric, and perforating lichen nitidus. We report a 7-year-old boy who presented with multiple generalized papular eruption that was composed of discrete, flesh colored, 1-2mm sized, glistening, and round shaped papules. The histopathology of the biopsied specimen showed a well-circumscribed dermal infiltrate mainly composed of histiocytes. The overlying epidermis showed atrophy, thinning of granular layer and liquifaction degeneration of basal layer. Transepidermal perforation was observed and eosinophilic amorphous debris was in the channel of the perforation.
