Figure 3.

A = histopathologic examination revealed epithelial atrophy, loss of rete pegs, hyalinization of the lamina propria and deep lymphohistiocytic inflammation (hematoxylin and eosin stain, original magnification x100).
B = hyalinization and loss of cellularity of the subepithelial lamina propria (hematoxylin and eosin stain, original magnification x200).
C = hyalinization and loss of cellularity of the subepithelial lamina propria (hematoxylin and eosin stain, original magnification x200).
D = histochemical Shikata's modified orcein stain revealed loss of elastin fibres in the hyalinized subepithelial area (original magnification x100).
E = normal deep connective tissue, stained with Shikata's modified orcein stain, showing plenty of brown-coloured elastin fibres in a perivascular orientation (original magnification x100).
