A conjunctival epithelial cyst is a rare lesion presenting as a soft mass. This case report highlights its characteristics and importance in diagnosing orbital masses.
Area of Science:
- Ophthalmology
- Dermatopathology
Background:
- Primary conjunctival epithelial cysts are uncommon lesions.
- Characterized by nonkeratinized, stratified squamous epithelium without dermal appendages.
Observation:
- A 57-year-old woman presented with a soft mass in the anterior nasal orbit.
- Imaging revealed a rounded, cystic lesion between the right eye and nasal bone.
Findings:
- Histopathology confirmed a conjunctival epithelial cyst.
- The cyst was lined by nonkeratinized cuboidal epithelium, lacking goblet cells and adnexal structures.
Implications:
- Conjunctival epithelial cysts should be considered in the differential diagnosis of anterior nasal or superonasal orbital masses.
- Accurate diagnosis aids in appropriate management and surgical planning.
