Keratoacanthomas is a very common skin lesion that occurs on sun-damaged skin. They may frequently arise on the face, ears, nose and limbs. Keratoacanthomas are thought to be a variant of an SCC, but KAs may resolve over months. Skin Cancer Doctors will often take a biopsy to tell the difference between KAs and SCCs. Keratoacanthomas present as a warty growth that can erupt over days to weeks, and rapidly grow over time. Early identification is best management.
