An elevated, gelatinous mass with neovascularization is the most common lesion appearance for which conjunctival lesion?

• A. Conjunctival nevus
• B. Pyogenic granuloma
• C. Conjunctival Intraepithelial Neoplasia (CIN)
• D. Conjunctival squamous cell carcinoma

Answer: (C)

This pattern points to a conjunctival intraepithelial neoplasia lesion. CIN is a premalignant squamous lesion of the conjunctiva that often presents as an elevated, semi-translucent or gelatinous mass with visible surface vessels. The gelatinous appearance comes from the thinned, edematous epithelium and underlying neovascularization feeding the abnormal tissue, giving a glistening, pinkish look at the surface. The vascular component is a hallmark, reflecting angiogenic activity in the neoplastic epithelium. This differs from a conjunctival nevus, which is typically pigmented and may contain cysts rather than a gelatinous surface. Pyogenic granuloma tends to be a rapidly enlarging, bright red, friable vascular lesion that bleeds easily, rather than a smooth, gelatinous mass. Conjunctival squamous cell carcinoma can be more aggressive with possible invasion, ulceration, or leukoplakia, but CIN most often presents with this gelatinous, vascular, elevated appearance. Because CIN is premalignant, a biopsy is essential for confirmation and management, which may include excision with close margins, cryotherapy, and adjunct topical chemotherapy or other treatments as indicated.
