Cutaneous Horns on the Nose and Ear: Association with Malignant and Premalignant Conditions – Two Case Reports

Cutaneous horns are hyperkeratotic lesions characterized by a horn-like appearance, varying in size from a few millimeters to several centimeters. These lesions are commonly located on areas of the skin with prolonged sun exposure, such as the face and ears. Cutaneous horns can develop in association with underlying benign, premalignant, or malignant conditions, or as a direct result of such alterations. This report presents two cases of patients who underwent surgical treatment for cutaneous horns located on the nasal and auricular regions, with actinic keratosis and squamous cell carcinoma identified as the underlying pathologies.
