Background:
A primary conjunctival epithelial cyst is an uncommon lesion that consists of nonkeratized, stratified squamous epithelium without dermal appendages.
Methods:
Case report.
Results:
A 57-year-old woman presented with a soft mass in the anterior portion of the nasal orbit. Magnetic resonance imaging demonstrated a rounded, cystic lesion between the right eye and the nasal bone. Histopathological examination following complete surgical excision disclosed a conjunctival epithelial cyst lined by nonkeratinized cuboidal epithelium without goblet cells and adnexal structures.
Conclusion:
A conjunctival epithelial cyst should be considered in the differential diagnosis of a mass in the anterior portion of nasal or superonasal orbit.
