title: Epidermoid cyst text: Epidermoid cyst An epidermoid cyst or epidermal inclusion cyst is a benign cyst usually found on the skin. The cyst develops out of ectodermal tissue. Histologically, it is made of a thin layer of squamous epithelium. The epidermoid cyst may have no symptoms, or it may be painful when touched. It can release macerated keratin. In contrast to pilar cysts, epidermoid cysts are usually present on parts of the body with relatively little hair. An epidermoid cyst is one type of vaginal cyst. Occasionally, an epidermoid cyst will present with trigeminal neuralgia. Although they are not malignant, there are rare title: Desquamation text: epidermal necrolysis (TEN). Radiation can cause dry or moist desquamation. Certain eye tissues, including the conjunctiva and cornea, may undergo pathological desquamation in diseases such as dry eye syndrome. The anatomy of the human eye makes desquamation of the lens impossible. Desquamation Desquamation (), commonly called skin peeling, is the shedding of the outermost membrane or layer of a tissue, such as the skin. Normal, nonpathologic desquamation of the skin occurs when keratinocytes, after moving typically over about 14 days, are individually shed unnoticeably. Obvious but nonpathologic visible desquamation can be observed after immersion of the skin in warm or title: Abrasion (medical) text: Abrasion (medical) An abrasion is a wound caused by superficial damage to the skin, no deeper than the epidermis. It is less severe than a laceration, and bleeding, if present, is minimal. Mild abrasions, also known as "grazes" or "scrapes", do not scar or bleed, but deep abrasions may lead to the formation of scar tissue. A more traumatic abrasion that removes all layers of skin is called an avulsion. Abrasion injuries most commonly occur when exposed skin comes into moving contact with a rough surface, causing a grinding or rubbing away of the upper layers of the epidermis. The title: Transepidermal water loss text: Transepidermal water loss Transepidermal water loss (TEWL or TWL) is the loss of water that passes from inside a body (animal or plant) through the epidermis (that is, either the epidermal layer of animal skin or the epidermal layer of plants) to the surrounding atmosphere via diffusion and evaporation processes. TEWL in mammals is also known as insensible water loss (IWL), as it is a process over which organisms have little physiologic control and of which they are usually mostly unaware. Insensible loss of body water can threaten fluid balance; in humans, substantial dehydration sometimes occurs before a person realizes title: Abrasion (medical) text: caused by sliding on concrete.
