Identity Profile: Corns
Definition:
A hard, conical projection of a yellowish-brown colour, either straight or curved, protruding from the skin, caused by an excessive growth of keratin (hyperkeratosis). It derives its name from its resemblance to an animal's horn. These skin outgrowths typically develop in areas frequently exposed to the sun, most commonly on the face, ears, and back of the hand. In approximately 60% of cases, these cutaneous horns are benign, but they can also be cancerous or precancerous.
Internal and external causes:
Often unknown; presence of viral warts caused by the human papillomavirus; exposure to sunlight; skin cancer; precancerous skin lesions.
How to reduce or eliminate:
Never attempt to remove a skin corn by yourself; consult a doctor; complete removal of the skin corn when malignancy is a major concern; laser therapy; electrocautery; freezing with liquid nitrogen.
Preventative steps to take:
There are no clear preventative measures; avoid sun exposure; apply a broad-spectrum, high-protection sunscreen daily.
