Insights
A rare congenital eyelid mass in a 7-week-old was diagnosed as a caruncular choristoma after surgical removal. This is the first reported case of caruncular tissue presenting externally on the eyelid.
Area of Science:
- Ophthalmology
- Pediatric Surgery
- Dermatopathology
Background:
- Congenital eyelid masses require accurate diagnosis and management.
- Caruncular choristomas are rare benign tumors typically found in the lacrimal caruncle.
Observation:
- A 7-week-old infant presented with a congenital mass on the external eyelid.
- The mass was surgically excised for evaluation.
Findings:
- Histopathologic examination confirmed the diagnosis of caruncular choristoma.
- This represents the first documented instance of caruncular tissue presenting as an external eyelid mass.
Implications:
- This case expands the known clinical presentations of caruncular choristomas.
- It underscores the need for comprehensive histopathological analysis of all eyelid masses, regardless of location.
Abstract:
A 7-week-old patient presented for evaluation of a congenital eyelid mass. Following surgical excision of the lesion, histopathologic diagnosis of caruncular choristoma was made. To the authors' knowledge, this is the first report of caruncular tissue presenting as an external eyelid mass.
