A Case of Solitary Nonvascularized Corneal Epithelial Dysplasia

Figure 4

Immunohistochemical detection of intermediate filament components in dysplastic epithelium. Keratin 12 (a) is not expressed in dysplastic epithelial cells (asterisk), while it is well detected in normal corneal epithelium (arrow) adjacent to the lesion. Keratin 13 (b) and keratin 14 (c) are readily detected in the dysplastic cells throughout the layers. Some of the dysplastic cells are labeled for vimentin (d).
