| Clinically,
this lesion is characterized by a thickening of the conjunctiva with
whitening or leukoplakia.
Histologically, these lesions are very similar to actinic keratosis
of the skin with the epithelium showing mild atypia with preservation of
normal polarity and maturation (#21888).
In addition, the underlying substantia propria may show
degenerative changes similar to that seen in a pterygium(#21886).
