Immunohistochemical detection of psoriasin in normal and psoriatic skin Pattern of psoriasin expression in normal skin and psoriatic lesions detected by immunohistochemistry. Psoriasin is absent from normal dermis, epidermis (A, double arrow), and eccrine glands (A & D, single arrow) but is expressed in hair follicles and occasional associated sebaceous glands (A & C, asterix).
