title: Cutaneous horns: are these lesions as innocent as they seem to be?
abstract: BACKGROUND
  Cutaneous horns (cornu cutaneum) are uncommon lesions consisting of keratotic material resembling that of an animal horn. Cutaneous horn may arise from a wide range of the epidermal lesions, which may be benign, premalignant or malignant.
  
  
  METHODS
  In this respective study, we describe our experience of eleven patients with cutaneous horn treated at our centre between January 2000 and January 2004. The clinical, pathological and treatment details were extracted from the case records. Data is presented as frequency distribution.
  
  
  RESULTS
  There were 8 male and 3 female patients with a median age of 57 years. Most of the lesions were located on the ear, hand and scalp. Surgical resection was carried out in all the lesions. There were two cases of squamous cell carcinoma, and one case of basal cell carcinoma, other 8 cases were benign. None of the lesions recurred and no adjuvant treatment was given to any of the malignant lesions.
  
  
  CONCLUSIONS
  Cutaneous horn is a clinical diagnosis that refers to a conical projection above the surface of the skin. The lesions typically occurs in sun exposed areas, particularly the face, ear, nose, forearms, and dorsum of hands. Even though our 60% of the cutaneous horns are benign possibility of skin cancer should always be kept in mind.
