Fingernail disorders. Artwork showing various disorders of the fingernail. There are white spots on the nail (far left) caused by a fungal infection or air bubbles under the nail. The nail at centre left is showing transverse white lines (Beau's lines), caused by heart disease or excess calcium in the blood. The nail at centre right is showing an abnormally curved shape, caused by over-exposure to chemicals such as hair dye or detergents. The nail at far right is bulging, which is usually caused by heart disease or respiratory problems. Fungal problems can be treated with drugs, but the cosmetic problems will not disappear until they have fully grown out.
