A **decubitus** **ulcer** is a pressure sore or what is commonly called a "bed sore". It can range from a very mild pink coloration of the skin, which disappears in a few hours after pressure is relieved on the area, to a very deep wound extending to and sometimes through a bone into internal organs. These ulcers, as well as other wound types, are classified in stages according to the severity of the wound. All decubitus ulcers have a course of injury similar to a burn wound. This can be a mild redness of the skin and/or blistering, such as a first-degree burn, to a deep open wound with blackened tissue, as in a third degree burn. This blackened tissue is called eschar.


 * Urticaria**: is a common type of skin disorder that involves blood vessels. It is also referred to as hives. This condition is characterized by raised red lesions called wheals caused by leakage of fluid from the skin's blood vessels. Urticaria is often associated with severe itching. Hypersensitivity or allergic reactions, physical irritants, and systemic diseases are common causes.
