To the Editor:Perforating dermatoses is a group of diseases characterized by papulonodular rashes with the elimination of endogenous or exogenous materials through the epidermis.The primary perforating disorders include reactive perforating collagenosis,elastosis perforans serpiginosa,Kyrle disease,perforating folliculitis,and acquired perforating dermatosis.The perforating phenomenon could also be secondary to some other skin disorders,such as calcinosis cutis,granuloma annulare,chromoblastomycosis,lichen planus,lichen striatus,and rarely,lichen nitidus.Herein,we report a case of extensive perforating lichen nitidus in a Chinese patient.
