Clinically, it appears in fair-skin patients between 60 and 70 years of age. It can also appear in immunosuppressed young people and it could be bilateral. CIN is a gelatinous sessile or papillomatous lesion exhibiting a tendency toward diffuse superficial extension, generally in the interpalpebral fissure, that affects the limbus with poorly defined edges and usually extends over the corneal epithelium. The development of CIN has involved the human papilloma virus (even more so in patients with bilateral disease or immunosuppression), the acquired immunodeficiency virus, exposure to sun and environmental factors such as petroleum derivates, industrial oils, tobacco smoking, etc.<a class="elsevierStyleCrossRef" href="#bib0055"><span class="elsevierStyleSup">1</span></a></p><p id="par0010" class="elsevierStylePara elsevierViewall">The term CIN (<span class="elsevierStyleItalic">conjunctival intraepithelial neoplasia</span>) includes the various degrees of dysplasia (slight, moderate and severe) and in situ carcinoma, which implies that these entities are different levels of development of intraepithelial neoplasia regarded as a pre-cancerous lesion because if the atypical cells break the basal membrane and invade the subconjunctival tissue, the result is invasive conjunctival squamous carcinoma. The risk of developing squamous carcinoma is low, but probably higher than the risk of developing actinic keratosis.</p><p id="par0015" class="elsevierStylePara elsevierViewall">Due to the lack of precision of its borders and its tendency to diffuse growth, incomplete resection is more likely to occur than in actinic keratosis, giving rise to frequent relapses. Compared to similar lesions in other locations, the course of CIN is relatively benign as it usually remains confined to the epithelium and rarely becomes invasive. The majority of these lesions do not follow the course of a typical malign, invasive and metastatic tumor. The degree of surface extension and recurrences are bigger problems than the potential of systemic extension of this type of tumor. Early diagnostic is important because excisional biopsy with resection margin, with or without adjuvant treatment, is generally a definitive treatment. However, advanced lesions could extend throughout the cornea and large parts of the conjunctiva, making complete extirpation difficult and thus endangering the visual function and requiring complex surgical operations and adjuvant treatments such as topical chemotherapy (mitomycin C, 5-fluorouracil [5-FU], interferon alpha-2b [INFα-2b]).<a class="elsevierStyleCrossRef" href="#bib0055"><span class="elsevierStyleSup">1</span></a></p><p id="par0020" class="elsevierStylePara elsevierViewall">Interferons are a family of glycoproteins with antitumoral and antiviral properties.
