This case report details the diagnosis and surgical treatment of epibulbar osseous choristoma, a rare tumor. Successful management of this benign conjunctival mass highlights effective treatment strategies for ocular choristomas.
Area of Science:
- Ophthalmology
- Pathology
Background:
- Epibulbar osseous choristoma is an extremely rare subtype of ocular choristoma.
- This benign tumor of the conjunctiva is characterized by the presence of well-differentiated bone tissue.
Observation:
- A 12-year-old female presented with a symptomatic conjunctival mass causing discomfort.
- Examination revealed a 5x5 mm firm nodule in the superotemporal quadrant with feeder vessels, adhered to the sclera.
- The mass showed no signs of malignancy.
Findings:
- Surgical excisional biopsy was performed under general anesthesia with careful technique to prevent globe perforation.
- Pathological examination confirmed well-circumscribed osseous tissue without cellular atypia, consistent with choristoma.
Implications:
- This report contributes to the limited literature on osseous choristoma, providing insights into diagnosis and surgical management.
- Successful treatment underscores the importance of accurate diagnosis and careful surgical intervention for this rare condition.
