A carbuncle is a red, swollen, and painful cluster of boils that are connected to each other under the skin. A boil (or furuncle) is an infection of a hair follicle that has a small collection of pus (called an abscess) under the skin
Boils and carbuncles are bacterial infections of hair follicles and surrounding skin that form pustules (small blister-like swellings containing pus) around the follicle. Boils are sometimes called furuncles. Carbuncles are formed when the bacteria infect several hair follicles that are close together. Carbunculosis is a word that is sometimes used to refer to the development of carbuncles. The abscesses spread until they merge with each other to form a single large area of infected skin with several pus-filled heads. For the meaning in material sciences, see spalling. Desquamation (from Latin desquamare, meaning to scrape the scales off a fish ), also called skin peeling, is the shedding of the outermost membrane or layer of a tissue, such as the skin. In pathologic desquamation, such as that seen in X-linked ichthyosis, the stratum corneum becomes thicker (hyperkeratosis), imparting a dry or scaly appearance to the skin, and instead of detaching as single cells, corneocytes are shed in clusters, forming visible scales. A carbuncle is a red, swollen, and painful cluster of boils that are connected to each other under the skin. A boil (or furuncle) is an infection of a hair follicle that has a small collection of pus (called an abscess) under the skin. Usually single, a carbuncle is most likely to occur on a hairy area of the body such as the back or nape of the neck. But a carbuncle also can develop in other areas of the body such as the buttocks, thighs, groin, and armpits. Carbuncles are more likely than boils to leave scars. An active boil or carbuncle is contagious: the infection can spread to other parts of the person's body or to other people through skin-to-skin contact or the sharing of personal items. Usually single, a carbuncle is most likely to occur on a hairy area of the body such as the back or nape of the neck. But a carbuncle also can develop in other areas of the body such as the buttocks, thighs, groin, and armpits. The corneal epithelium (epithelium corneae corneæ anterior) layer is made up of epithelial tissue and covers the front of the. Cornea it acts as a barrier to protect the, cornea resisting the free flow of fluids from the, tears and prevents bacteria from entering the epithelium and corneal. stroma The corneal epithelium consists of several layers of cells. The cells of the deepest layer are columnar, known as basal cells. Then follow two or three layers of polyhedral cells, commonly known as wing cells. The majority of these are prickle cells, similar to those found in the stratum mucosum of the cuticle. Boils and carbuncles are firm reddish swellings about 0.2-0.4in (5-10 mm) across that are slightly raised above the skin surface. They are sore to the touch. A boil usually has a visible central core of pus; a carbuncle is larger and has several visible heads. Boils occur most commonly on the face, back of the neck, buttocks, upper legs and groin area, armpits, and upper torso. Carbuncles are formed when the bacteria infect several hair follicles that are close together. Carbunculosis is a word that is sometimes used to refer to the development of carbuncles. The abscesses spread until they merge with each other to form a single large area of infected skin with several pus-filled heads. Bacterial skin infections can be spread by shared cosmetics or washcloths, close human contact, or by contact with pus from a boil or carbuncle. As the infection develops, an area of inflamed tissue gradually forms a pus-filled swelling or pimple that is painful to touch. Carbuncles are formed when the bacteria infect several hair follicles that are close together. Carbunculosis is a word that is sometimes used to refer to the development of carbuncles. The abscesses spread until they merge with each other to form a single large area of infected skin with several pus-filled heads. Overview / Basic structure of the eyeball. The eyeball consists of three principal layers. 1  The outer layer, or sclera, consists of dense fibrous connective tissue. 2  The sclera is white of the eye. 3  The sclera is continuous with the transparent substantia propria of the cornea. 1 The exposed front surface of the eye, including the cornea, is also covered by a thin, non-keratinized stratified squamous epithelium. 2  The next layer, or choroid, consists of heavily pigmented loose connective tissue, including many melanocytes. 3  The choroid is normally not visible behind the white of the sclera. Boils and carbuncles are often caused by a type of bacteria known as Staphylococcus aureus (staph bacteria) infecting one or more hair follicles. Staph bacteria usually live harmlessly on the surface of the skin or in the lining of the nose. Boils tend to occur when the bacteria enters the skin through cuts and grazes. This causes your immune system to respond by sending infection-fighting white blood cells to kill the bacteria. Over time, a mix of dead bacteria, dead white blood cells and dead skin cells builds up inside the boil to form pus. Carbuncles. A carbuncle is a dome-shaped collection of boils that usually develops over the space of a few days. They most often occur on the back, thighs, or the back of the neck. A fully grown carbuncle can be more than 10cm (4 inches) in size, and will leak pus from a number of points.
