Figure 1

Representative images of the pterygium. (a) Low-power image showing the epithelium of varying thickness, hemorrhagic areas, and pronounced solar elastosis. (b) Stromal plaques underneath thinning epithelium. (c) Epithelial acanthosis and atrophy pronounced solar elastosis forming plaques. (d) Neovascularization and hemorrhage, mild solar elastosis. (e) Goblet cell hyperplasia with acanthosis, neovascularization, and mild solar elastosis. (f) Goblet cell hyperplasia, melanocytic hyperplasia, acanthosis, neovascularization, and lymphocytic infiltrate. (g) Basal cell hyperplasia, neovascularization, and solar elastosis. (h) Basilar hyperplasia, neovascularization, and mild elastosis. (i) Acanthosis and acute and chronic inflammation composed of neutrophils, eosinophils, histiocytes, and lymphocytes. (j) Lymphoplasmacytic infiltrates and histiocytes in a mucinous stroma.
