Introduction: Conjunctival/corneal intraepithelial neoplasms are premalignant lesions usually showing conjunctival or limbal involvement. We report the rare case of an isolated corneal intraepithelial lesion.
Clinical case: An 80-year-old woman with an elevated, avascular, well-demarcated grey corneal plaque. After epitheliectomy and alcohol, the excised lesion was identified as a high-grade epithelial neoplasia. Treatment was topical interferon α-2b for 1 month without recurrences.
Conclusions: A well-defined greyish corneal opacity should always raise suspicion of an intraepithelial neoplasia. In the present case, epitheliectomy and topical recombinant interferon proved successful.
