Doctor taking a shave biopsy of a cutaneous horn on a patient's chest. Cutaneous horns result from an overgrowth of the skin protein keratin. They are slow-growing and may vary in colour from yellow to black independent of skin colour. This horn developed where there was previously a wart on the skin. Treatment is with surgical removal. For this image before the biopsy see C060/4128 and for after the biopsy see C060/4131.
