Summary
Pterygium, a common eye lesion, can sometimes conceal conjunctival intraepithelial neoplasia. Pathological examination is crucial for accurate diagnosis, even in seemingly benign cases.
Area of Science:
- Ophthalmology
- Oncology
Background:
- Pterygium is a common, typically benign, wing-shaped growth on the conjunctiva.
- Conjunctival intraepithelial neoplasia (CIN) is a pre-malignant lesion of the eye's surface.
Observation:
- A case study involving a 53-year-old male with a long-term resident of Kenya.
- An apparently trivial pterygium exhibited an atypical grayish area.
Findings:
- Histological examination of the pterygium revealed an underlying conjunctival intraepithelial neoplasia.
- This highlights the importance of pathological assessment for seemingly benign ocular surface lesions.
Implications:
- Ophthalmologists should consider pathological examination for suspicious areas within pterygium.
- Early detection of CIN can prevent progression to invasive squamous cell carcinoma.
- This case underscores the need for vigilance in diagnosing ocular surface lesions, particularly in endemic regions.
