Dermatology is the branch of medicine that deals with the prevention, diagnosis and treatment of skin diseases. Doctors who specialize in this field are called dermatologists. Skin ailments treated by dermatologists include inflammations, infections, burns and tumours. Dermatologists also treat many children and teenagers who have acne or certain allergies. Dermatologists are trained to recognize changes in the skin that indicate a disease in other parts of the body. For example, a certain type of facial rash may be a symptom of systematic lupus erythematosus, a disease that affects many internal organs as well as the skin. Dermatology includes research on the structure and function of skin. Some dermatologists perform surgery to correct certain conditions.
Skin colour - Skin colour depends mainly on the amount of brown pigment, called melanin, in the skin. In light skin, below left, cells known as melanocytes produce a small amount of melanin. In dark skin, below right, these cells produce more melanin. The nails of the fingers and toes are formed from certain cells of the skin. A nail has three parts—the matrix, bed, and plate. The matrix produces the cells of the bed and plate.
