Which description best matches CIN/SCC on an anterior segment photo?

• A. Gelatinous, elevated lesion that can be gray, pink, or brown and well-vascularized, sometimes extending onto the cornea
• B. Flat brown lesion with no cysts
• C. Red, inflamed conjunctiva with discharge
• D. Pigmented lacrimal sac lesion

Answer: (A)

CIN/SCC on the anterior segment is best recognized as a raised, gelatinous conjunctival lesion that is well vascularized and can appear gray, pink, or brown, with the potential to extend onto the cornea. This combination of an elevated, translucent to opaque, vascular growth that may reach onto the corneal surface is characteristic of conjunctival intraepithelial neoplasia and squamous cell carcinoma. Other descriptions describe flat pigmented spots or inflammatory changes, which don’t match the appearance of an abnormal mass invading the conjunctiva and sometimes the cornea.
