Severe cutaneous adverse reactions (SCARs) are a group of potentially lethal adverse drug reactions that involve the skin and mucous membranes of various body openings such as the eyes, ears, and inside the nose, mouth, and lips. In more severe cases, SCARs also involves serious damage to internal organs. SCARs includes five syndromes:
Schamberg's disease is a skin disorder that causes a discoloration of the lower extremities. [4] It usually occurs in the lower extremities and rarely elsewhere. [4] This condition is caused by leaky blood vessels near the surface of the skin. [7] The cause of the leaky capillaries is usually not known. [7]
A number of additional factors appear to promote the appearance of stretch marks: one study of 324 women, done just after they had given birth, demonstrated that low maternal age, high body mass index, weight gain over 15 kg (33 pounds) and higher neonatal birth weight were independently correlated with the occurrence of striae. Teenagers were ...
In a normal case, the swelling will decrease without treatment within 15–30 minutes, but, in extreme cases, itchy red welts may last anywhere from a few hours to days. In some cases, welts are accompanied with a painful burning sensation. [3] This calls for more urgent treatment as the condition can impact on the patient's quality of life.
The scar tissue may be located inside the knee joint or may involve the soft tissue structures around the knee joint, or both locations. The pathology that causes arthrofibrosis also causes other forms of fibrosis.
The exact cause of lipodermatosclerosis is unknown. [3] [6] Venous disease, such as venous incompetence, venous hypertension, and body mass may be relevant to the underlying pathogenesis. [3] Increased blood pressure in the veins (venous hypertension) can cause diffusion of substances, including fibrin, out of capillaries.
Scarification can be used to transmit complex messages about identity; such permanent body markings may emphasize fixed social, political, and religious roles. [1] Tattoos, scars, brands, and piercings, when voluntarily acquired, are ways of showing a person's autobiography on the surface of the body to the world. [7]
A hypertrophic scar is a cutaneous condition characterized by deposits of excessive amounts of collagen which gives rise to a raised scar, but not to the degree observed with keloids. [1] Like keloids, they form most often at the sites of pimples, body piercings , cuts and burns.
