A skin growth caused by an overproduction of keratin. Keratoses occur mainly in elderly people. Seborrhoeic keratoses are harmless growths that occur mainly on the trunk. The growths range in appearance from flat, dark-brown patches to small, wart-like protrusions. They do not need treating unless they are unsightly. Solar keratoses are small, wart-like, red or flesh-coloured growths that appear on exposed parts of the body as a result of overexposure to the sun over many years. Rarely, they may develop into skin cancer, usually squamous cell carcinoma, and must be surgically removed.
