Cutaneous Horn of the Eyelid: Anatomoclinical Implications

The cutaneous horn (cornu cutaneum) is a circumscribed,conical and keratotic lesion, which can hide benign or malignant lesions [1-3]. The clinical diagnosis is established based on its appearance, the lesion being classified as solitary or multiple, straight, curved or twisted, white or yellow [4,5], most often located at the level of the skin on the patient's face [4,6,7]. While the cause leading to the formation of cutaneous horns [8] is unknown, UV radiations are believed to be the trigger of this condition [9]. Usually, the cutaneous horn occurs in people over the age of 50, in both genders [10-14].
