Epithelial Inclusion Cyst
A conjunctival epithelial inclusion cyst may form at a site of prior accidental or surgical trauma (eg, after strabismus surgery, retinal surgery, or enucleation). Clinically, the lesion appears as a clear, translucent cystic elevation on the ocular surface. There may be associated prominent vascularity. Histologic examination shows a cystic space in the stroma lined by nonkeratinized stratified squamous epithelium with or without goblet cells (Fig 5-14A). The lumen may be empty or may contain proteinaceous material and cellular debris (Fig 5-14B).
