The skin is the largest organ of the body. In the skin there are cells called 'melanocytes'. These are cells which are found in the epidermis and produce 'melanin'. Melanin is a pigment and is responsible for giving us our skin colour. Sometimes, groups of melanocytes cluster together and that is when a 'mole' is formed.

Moles are correctly called melanocytic naevus, but they can be called many other different names, including pigmented lesion and freckle. Here are examples of different harmless melanocytic naevus, but these can vary enormously from person to person.
