Summary
Congenital orbital teratoma is a rare tumor found in newborns. This case highlights a teratoma without an organized eye, emphasizing the need for prompt diagnosis and surgical intervention in neonates with orbital masses.
Area of Science:
- Ophthalmology
- Pediatric Surgery
- Developmental Biology
Background:
- Congenital orbital masses are rare in neonates.
- Teratomas, tumors with tissues from all three germ layers, can occur in various locations.
- Orbital teratomas present a diagnostic and surgical challenge, especially when lacking organized ocular structures.
Observation:
- A newborn male presented with a large (10x8 cm) congenital orbital teratoma extruding from the left orbit.
- Magnetic resonance imaging (MRI) revealed a complex cystic-solid mass with calcifications, deforming the bony orbit.
- No organized eye or intracranial extension was identified within the orbital mass.
Findings:
- Histopathological examination confirmed a teratoma, with elements from ectoderm, mesoderm, and endoderm.
- The teratoma contained disorganized ocular tissues but lacked a formed eye.
- Surgical excision of the mass and subsequent eyelid reconstruction were performed.
Implications:
- This case underscores the importance of considering congenital orbital teratoma in the differential diagnosis of neonatal orbital masses.
- Early surgical intervention is crucial for managing orbital teratomas, potentially preserving ocular structures when feasible.
- Awareness among neonatologists and pediatricians can facilitate timely diagnosis and treatment, improving outcomes for affected infants.
