Figure 3: (a) Subepidermal cleft and amyloid deposition in the entire dermis was positive with violet staining (×100) and (b) Congo red staining (×40), also positive for apple-green birefringence with polarized light (not shown). (c) Immunohistochemistry staining showed strong positivity for λ light chain (×200) and (d) less intensity for κ light chain (×200)
