(a) Junction between nonlesional (right) and lesional (left) skin of psoriasis showing only membranous staining (nonlesional) while both membranous and nuclear beta-catenin (β-catenin) expression is seen in lesional skin (IPS, ×400). (b) Membranous β-catenin expression together with positive dermal inflammatory components in nonlesional skin of psoriasis (Immunoperioxedase stain, ×200). (c) Nuclear and cytoplasmic β-catenin expression in normal hair follicle matrix cell (Immunoperioxedase stain, ×400)
