Summary
A rare benign tumor, peribulbar osseous choristoma, is a bony growth under the conjunctiva. This case report details the diagnosis and surgical removal of this extremely uncommon epibulbar choristoma.
Area of Science:
- Ophthalmology
- Pathology
- Oncology
Background:
- Epibulbar choristomas are rare congenital tumors composed of tissue not normally found in the eye.
- Peribulbar osseous choristoma, a subtype of epibulbar choristoma, is exceptionally rare, comprising pure bony tissue.
- This subtype is the rarest, with fewer than 70 cases documented since the 19th century.
Observation:
- A 7-year-old female presented with a congenital, painless, superotemporal mass under the conjunctiva of her left eye.
- Initial differential diagnoses included lipodermoid or a subconjunctival foreign body.
- Diagnostic procedures involved B-scan ultrasonography and examination under anesthesia.
Findings:
- Surgical excision of the mass was performed.
- Histopathological examination confirmed the diagnosis of osseous choristoma.
- The tumor consisted solely of mature bone tissue.
Implications:
- This report highlights the rarity and clinical presentation of peribulbar osseous choristoma.
- Accurate diagnosis through histopathology is crucial for appropriate management.
- Understanding this rare condition aids ophthalmologists in recognizing and treating similar pediatric ocular masses.
