To view blood flow through your heart, your doctor may inject a special dye into your coronary arteries. This is known as an angiogram. The dye is injected into the arteries of the heart through a long, thin, flexible tube (catheter) that is threaded through an artery, usually in the leg, to the arteries in the heart.
A wart is a small growth with a rough texture that can appear anywhere on the body. It can look like a solid blister or a small cauliflower. Warts are caused by viruses in the human papillomavirus (HPV) family. The appearance of a wart depends on its location on the body and the thickness of the skin. Palmar warts appear on the hand. Plantar warts affect the feet. As many as 1 in 3 children and teenagers are estimated to have warts, but only 3 to 5 percent of adults.
Sometimes plantar warts can grow in clusters; those are called mosaic warts. Sometimes corns or calluses are mistaken for a palmer or plantar wart. In some warts, little black dots appear, leading people to call them seed warts. Actually the black dots are little blood vessels that have grown up into the wart.
