An acquired deformity of the external ear to which wrestlers and boxers are particularly vulnerable, due to trauma. When a blood clot (hematoma) forms under the skin of the ear, the clot disrupts the connection of the skin to the ear cartilage. The cartilage has no other blood supply except from the overlying skin, so if the skin is separated from the cartilage, it is deprived of nutrients and dies. The ear cartilage then shrivels up to form the classic cauliflower ear, so named because the tissue resembles that lumpy vegetable’s surface. Treatment involves draining the blood clot through an incision in the ear and then applying a compressive dressing, to sandwich the two sides of the skin against the cartilage.
- Cauliflower-ear deformity
Destruction of the underlying cartilage framework of the outer ear (pinnae), usually caused by either infection or trauma, resulting in a thickening of the ear. Classically, blood collects (hematoma) between the ear cartilage and the skin. There is a marked thickening of the entire ear which may be so extensive that the shape of the […]
Causalgia: Intense burning pain and sensitivity to the slightest vibration or touch, usually in the hand or foot, at a site some distance removed from a wound that has healed.
- Causes of cancer
Causes of cancer. In most individual cases, the exact cause of cancer is unknown. It’s likely that each case represents an interplay of several factors, which may include increased genetic susceptibility; environmental insults, such as chemical exposure or smoking cigarettes; lifestyle factors, including diet; and damage caused by infectious disease. Although they are not causes […]
Cauterization: The use of heat to destroy abnormal cells. Also known as diathermy and electrodiathermy.
Caveola: An tiny pit, grotto, depression, incupping in the surface of a cell. The name “caveola” means little cave. The plural is caveolae. Caveolae normally function to facilitate the uptake of fluid by the cell. In the process of pinocytosis, the caveolae close and pinch off to form pinosomes, little fluid-filled bubbles within the cell. […]
