Summary
A unilateral retinoblastoma case highlights the risk of orbital recurrence after enucleation. Chemotherapy effectively treated the recurrence, achieving 12 months of remission.
Area of Science:
- Ophthalmology
- Pediatric Oncology
Background:
- Retinoblastoma is the most common primary intraocular malignancy in children.
- Unilateral retinoblastoma often necessitates enucleation when visual prognosis is poor.
Observation:
- A 9-month-old boy presented with unilateral retinoblastoma and buphthalmos, undergoing primary enucleation.
- Histology revealed massive choroidal invasion but a tumor-free optic nerve, precluding adjuvant therapy.
Findings:
- Despite initial enucleation, the patient developed massive orbital retinoblastoma with conjunctival exposure three months post-surgery.
- Systemic chemotherapy led to remission, maintained for 12 months.
Implications:
- This case underscores the potential for orbital recurrence of retinoblastoma even with negative optic nerve margins.
- Prompt chemotherapy is crucial for managing orbital recurrence and achieving long-term remission.
- Understanding risk factors for orbital recurrence is vital for optimizing treatment strategies in retinoblastoma management.
