Summary
A rare conjunctival orbital cyst, a cystic mass lined with squamous epithelium, was diagnosed in a young male patient. This case represents the first reported instance in Taiwan and Asia.
Area of Science:
- Ophthalmology
- Pathology
Background:
- Orbital tumors can present as slow-growing masses.
- Conjunctival cysts are uncommon orbital lesions.
Observation:
- A 24-year-old male presented with a 3-year history of a superonasal left orbital mass.
- Ophthalmological examination revealed a firm mass in the left upper eyelid.
- CT scan showed a well-defined cystic mass without bony involvement.
Findings:
- Histopathological examination revealed a cystic structure lined with nonkeratinized squamous epithelium containing goblet cells.
- The lesion was identified as a primary conjunctival orbital cyst.
Implications:
- This case is the first reported instance of a primary conjunctival orbital cyst in Taiwan.
- This finding contributes to the understanding of rare orbital pathologies in Asia.
- Highlights the importance of histopathological diagnosis for orbital cystic lesions.
