Facial cutaneous horn in three different conditions: A highlight of a malignancy risk

INTRODUCTION: Cutaneous horns are nodules composed of compact keratin that project above the surface of the skin. The purpose of this work is to show the danger that can constitute the cutaneous horns. PRESENTATION OF CASES: In this paper, the authors report series of three cases of facial cutaneous horns, which were respectively diagnosed as trichilemmal horn in a 79-years old patient, a cutaneous horn underlying epidermoid carcinoma in a 59-years old patient, and a basal cell carcinoma in an 80-years old patient. All patients were treated by surgical excision. DISCUSSION: Cutaneous horns are generally asymptomatic and generate above all cosmetic disorders placing the patient in great social discomfort, thus prompting him to seek medical advice. CONCLUSION: They emphasize the need for careful management of these lesions because of the high incidence of malignant histology.
