A cutaneous horn could be defined as a conical projection on the surface of skin made of cornified material and resembling
an animal horn. These lesions most commonly affect light-skinned men aged between 50 to 89 years and usually
appear in sun exposed areas. Radiation, chronic irritation and even human papilloma virus-2 infection may be precipitating
factors. More than half of the cases originate from either malignant or premalignant lesions, therefore the base
of the lesion must be carefully examined histologically. Long standing presence of the lesion, conspicuous protrusion of the
horn and pain are positive predictive factors for malignancy and invasivity. In these cases an invasive surgical approach
is needed.
