Cutaneous Horn

 

Cutaneous Horn can be defined as a clinical diagnosis for a conical projection above the skin surface that appears similar to a miniature horn. While the base of the horn could be flat or nodular, it contains compacted keratin. There have been many different histologic lesions that have been documented at this base, the confirmation of which is essential for ruling out malignant changes. There are no clinical features that can clearly distinguish benign lesions from malignant lesions. Malignancy can be attributed to tenderness at the horn base and lesions of large size. Since the horn contains keratin, it can normally be removed through a sterile razor, though treatments may vary from a surgery, to radiation therapy or chemotherapy.
