[Bilateral actinic keratosis of the corneal limbus. Apropos of a case].

Keratinised tumors of the conjunctiva are not uncommon lesions. However, different pathological lesions may have a similar clinical. Actinic keratosis is one of these, it is an epithelial pre-cancerous lesion of the conjunctiva, which may become, if untreated, an invasive carcinoma. A case of bilateral lesions of this type is reported in a 61-year-old male patient who used to work outdoors, and the clinical diagnosis was followed by bilateral surgical removal of the two lesions. Histological examination study showed that the acquired modifications of the epithelium were typical of conjunctival actinic keratosis.
