Summary
A rare orbital odontogenic choristoma, presenting as a cystic mass with a molar tooth, recurred after surgery in a young girl. Complete excision is crucial to prevent recurrence of this orbital tumor.
Area of Science:
- Ophthalmology
- Oral and Maxillofacial Surgery
- Pathology
Background:
- Orbital tumors can present with varied clinical and histopathological features.
- Odontogenic choristomas are rare benign tumors composed of odontogenic tissues.
- Orbital choristomas are exceptionally rare, with few documented cases.
Observation:
- A 7-year-old girl presented with a recurrent, painless, firm to cystic mass in the infero-temporal orbit.
- The mass caused astigmatism, affecting vision, and was associated with a cutaneous sinus.
- Initial MRI suggested a mature teratoma; however, excision revealed a molar tooth within a cyst.
Findings:
- Histopathological examination confirmed the diagnosis of orbital odontogenic choristoma.
- The tumor contained mature odontogenic tissues, including a fully developed molar tooth.
- The presence of a cutaneous sinus indicated a connection to the skin surface.
Implications:
- This case highlights the importance of considering odontogenic choristoma in the differential diagnosis of orbital masses.
- Complete surgical excision is essential for managing orbital odontogenic choristoma and preventing recurrence.
- The unusual location and association with a cutaneous sinus underscore the need for thorough evaluation and management of such rare orbital tumors.
