Sumario:We report a case of conjunctival intraepithelial neoplasia (CIN) in a patient presenting with the pigmented conjunctival lesion. This study involved a 56-year-old woman that presented with right eye irritation for 1 month. She noticed brownish pigmentation arising from her right nasal conjunctiva and growing slowly over time. Biomicroscopic examination showed a gelatinous pigmented conjunctival mass with feeder vessels. Conjunctival impression cytology (CIC) was done and reported as CIN. Treatment was started with 0.02% mitomycin-C eye drops. The conjunctival lesion responded well to medication. This report shows that CIN can manifest as a pigmented tumor, resembling melanoma. CIC plays a role in the diagnosis of this condition. This tumor responded well with 0.02% mitomycin-C eye drops.
