One female patient in seventy-four years old presents one hyperkeratotic neoformation which covers upper eyelid, external canthus, lower eyelid in external part and palpebral fissure of the right eye. The affection appeared fifteen years ago. The extirpation was made eight years ago, relapsed and established one corneal ulcer. Extirpation of tumoral formation first of deeper eyelid and than of lower eyelid with cutaneous free skin graft it practised. Anatomopathological exam confirms the diagnosis of keratoacanthoma with acanthosis, hyperkeratosis and dyskeratosis of pluristratified epithelium. The basal membrane, is preserved, but it is masked here and there by an discreet chronic inflammatory process. It insists over the differential diagnosis with spinocellular epithelioma, the patient remaining in observation.
