Insights
A rare epibulbar complex choristoma in an infant was surgically removed. Despite a clear graft, the condition led to amblyopia, highlighting the challenges of this congenital eye tumor.
Area of Science:
- Ophthalmology
- Pediatric Surgery
- Pathology
Background:
- Congenital epibulbar tumors are rare, presenting unique diagnostic and management challenges in infants.
- Epibulbar complex choristomas, containing diverse tissue types, require specialized surgical intervention.
Observation:
- A male infant presented with a fleshy mass at the temporal bulbar conjunctiva and cornea of the right eye shortly after birth.
- The mass was surgically excised, and a lamellar keratoplasty was performed four weeks postpartum.
Findings:
- Histopathology confirmed the excised mass as an epibulbar complex choristoma, comprising cartilage, lacrimal gland lobules, and adipose tissue.
- Post-surgery, the corneal graft remained transparent, but the infant developed amblyopia in the affected right eye.
Implications:
- This case underscores the rarity and potential visual complications, such as amblyopia, associated with epibulbar complex choristomas.
- Early diagnosis and surgical management are crucial, but long-term visual outcomes require careful monitoring for conditions like amblyopia.
Abstract:
A male infant was born with a fleshy mass between the temporal bulbar conjunctiva and cornea in the right eye. Four weeks after birth the patient underwent excision of the epibulbar tumor and a lamellar keratoplasty. Histopathologic examination of the excised tumor revealed cartilage, lobules of lacrimal gland, and adipose tissue, indicating an epibulbar complex choristoma. Although the graft remained almost completely transparent, right amblyopia ensued. Epibulbar complex choristoma involving the conjunctiva and cornea is a rare condition.
