(a–c) Case 1, (d) Case 2, and (e, f) Case 3. (a) Gross tissue specimens. (b–f) Photomicrographs. (b) Normal-appearing oral mucosa, covered by parakeratinized squamous epithelium (E) with long interconnecting rete pegs (double arrows) and medium-sized vessels (arrows) (hematoxylin and eosin stain, original magnification ×200). (c) Lamina propria (LP) composed of fibrous connective tissue. Notice the many fibroblasts (purple nuclei) and a capillary vessel (arrow) (hematoxylin and eosin stain, original magnification ×400). (d) Pan-keratin-positive parakeratinized squamous epithelium (E) (streptavidin-biotin-peroxidase immunohistochemistry, original magnification ×200). (e, f) Normally distributed CD34-positive capillary vessels (brown) (streptavidin-biotin-peroxidase immunohistochemistry, original magnification (e) ×100, (f) ×400).
