Dermatitis, atopic
A skin disease characterized by areas of severe itching, redness, scaling, and loss of the surface of the skin (excoriation). When the eruption (rash) has been present for a prolonged time, chronic changes occur due to the constant scratching and rubbing known as lichenification (thickening of the skin with accentuation of the skin lines to form a crisscross pattern). This disorder usually affects young children on the face and extensor surfaces of the arms and legs (elbow and knee sides). Older children and adults are usually affected on the sides of the neck and on the inside of the elbow and knee.

A common type of benign skin tumor that is small, slow-growing, typically firm, red-to-brown and most often on the legs. Also called a fibrous histiocytoma. They can grow up to about 1 cm (less than a half inch) in diameter. A dermatofibroma consists of a proliferation of scar-like tissue within the deeper layers of the skin (dermis). The cause of dermatofibromas is unknown. They are usually single but sometimes may be multiple. Simple excision is curative.

Dermatofibromas
A slowly growing benign skin nodule consisting of poorly demarcated cellular fibrous tissue enclosing collapsed capillaries with scattered hemosiderin-pigmented and lipid macrophages. They are common, usually about 1 cm in diameter and occur in the dermis. Simple excision is always curative. (From Stedman, 25th ed; DeVita Jr et al., Cancer: Principles & Practice of Oncology, 3d ed, p1356)

Dermatofibrosarcoma
A fibrosarcoma of the skin, beginning most often as an indurated nodule that grows slowly and hence is often ignored until it grows large. Dermatofibrosarcomas show an extremely aggressive tendency to invade local surrounding tissue. They do not metastasize, however, even after multiple recurrences. About 50% will recur after simple incision; hence wide excision should be resorted to. (DeVita Jr et al., Cancer: Principles & Practice of Oncology, 3d ed, p1356)

Dermatofibrosarcoma protuberans
(DFSP) A type of skin tumor that begins as a hard nodule and grows slowly. DFSP is usually found in the dermis of the limbs or trunk of the body. (The dermis is the inner layer of the two main layers of tissue that make up the skin.) DFSP can grow and invade surrounding tissues but typically it does not metastasize (spread) to other more distant parts of the body. The cytogenetic hallmark of DFSP is an extra ring chromosome containing material from chromosomes 17 and 22, or, less frequently, a translocation between chromosomes 17 and 22. These chromosome rearrangements in DFSP fuse the COL1A1 gene on chromosome 17 to the PDGFB gene on chromosome 22. COL1A1 is type 1 alpha-1 chain of collagen while PDGFB is platelet-derived growth factor receptor B. Gleevec (imatinib), a targeted-gene drug which was developed to treat chronic myeloid leukemia (CML), is reportedly effective in slowing the growth of DFSP in most cases. Gleevec acts in this regard by inhibiting the PDGFB receptor.

Dermatofibrosarcomas
A fibrosarcoma of the skin, beginning most often as an indurated nodule that grows slowly and hence is often ignored until it grows large. Dermatofibrosarcomas show an extremely aggressive tendency to invade local surrounding tissue. They do not metastasize, however, even after multiple recurrences. About 50% will recur after simple incision; hence wide excision should be resorted to. (DeVita Jr et al., Cancer: Principles & Practice of Oncology, 3d ed, p1356)

Older women (perhaps because estrogen deficiency may increase the risk of infection), and men and women with diabetes or disease of the small blood vessels (peripheral vascular disease) are at increased risk. Artificial nails (acrylic or "wraps") increase the risk because when an artificial nail is applied, the nail surface is usually abraded with an emery board damaging it, emery boards can carry infection, and water can collect under the nail creating a moist, warm environment for fungal growth. Alternative names include tinea unguium.

Dermatotoxins
Specific substances elaborated by plants, microorganisms or animals that cause damage to the skin; they may be proteins or other specific factors or substances; constituents of spider, jellyfish or other venoms cause dermonecrosis and certain bacteria synthesize dermolytic agents.

Dermicidin
A potent anti-infective agent that is a natural component of sweat. The first antimicrobial agent found that is produced by cells in the skin, dermicidin is reportedly active against many different types of bacteria (including Escherichia coli (E. coli), Enterococcus faecalis, and Staphylococcus (Staph) aureus) and the common fungus Candida albicans. B102Dermicidin is also the name of the gene that encodes the protein product, dermicidin.

Dermis

Dermodress
A polypeptide substance comprising about one third of the total protein in mammalian organisms. It is the main constituent of SKIN, CONNECTIVE TISSUE, and the organic substance of bones (BONE AND BONES) and teeth (TOOTH).

Dermoid
Also called a dermoid cyst of the ovary, this is a bizarre tumor, usually benign, in the ovary that typically contains a diversity of tissues including hair, teeth, bone, thyroid, etc. A dermoid cyst develops from a totipotential germ cell (a primary oocyte) that is retained within the egg sac (ovary). Being totipotential, that cell can give rise to all orders of cells necessary to form mature tissues and often recognizable structures such as hair, bone and sebaceous (oily) material, neural tissue and teeth. Dermoid cysts may occur at any age but the prime age of detection is in the childbearing years. The average age is 30. Up to 15% of women with ovarian teratomas have them in both ovaries. Dermoid cysts can range in size from a centimeter (less than a half inch) up to 45 cm (about 17 inches) in diameter.

Dermoid cyst
A congenital (born with) tumor present in infancy as a yellowish swelling on the surface of the eye. It may enlarge during puberty. The dermoid cyst can be surgically removed by an ophthalmologist.

Dermoid Cyst
A tumor consisting of displaced ectodermal structures along the lines of embryonic fusion, the wall being formed of epithelium-lined connective tissue, including skin appendages, and containing keratin, sebum, and hair. (Stedman, 25th ed)

Dermoid cyst of the ovary
A bizarre tumor, usually benign, in the ovary that typically contains a diversity of tissues including hair, teeth, bone, thyroid, etc. A dermoid cyst develops from a totipotential germ cell (a primary oocyte) that is retained within the egg sac (ovary). Being totipotential, that cell can give rise to all orders of cells necessary to form mature tissues and often recognizable structures such as hair, bone and sebaceous (oily) material, neural tissue and teeth. Dermoid cysts may occur at any age but the prime age of detection is in the childbearing years. The average age is 30. Up to 15% of women with ovarian teratomas have them in both ovaries. Dermoid cysts can range in size from a centimeter (less than a half inch) up to 45 cm (about 17 inches) in diameter. These cysts can cause the ovary to twist (torsion) and imperil its blood supply. The larger the dermoid cyst, the greater the risk of rupture with spillage of the greasy contents which can create problems with adhesions, pain etc. Although the large majority (about 98%) of these tumors are benign, the remaining fraction (about 2%) becomes cancerous (malignant). Removal of the dermoid cyst is usually the treatment of choice. This can be done by laparotomy (open surgery) or laparoscopy (with a scope). Torsion (twisting) of the ovary by the cyst is an emergency and calls for urgent surgery. Dermoid cysts of the ovary are also called simply dermoids or ovarian teratomas.

Dermoid Cysts
A tumor consisting of displaced ectodermal structures along the lines of embryonic fusion, the wall being formed of epithelium-lined connective tissue, including skin appendages, and containing keratin, sebum, and hair. (Stedman, 25th ed)

Dermoids
A tumor consisting of displaced ectodermal structures along the lines of embryonic fusion, the wall being formed of epithelium-lined connective tissue, including skin appendages, and containing keratin, sebum, and hair. (Stedman, 25th ed)

Dermolysins
Protein exotoxins from Staphylococcus aureus, phage type II, which cause epidermal necrolysis. They are proteins with a molecular weight of 26,000 to 32,000. They cause a condition variously called scaled skin, Lyell or Ritter syndrome, epidermal exfoliative disease, toxic epidermal necrolysis, etc.

Dermopathy
Any disease of the skin. Synonymous with dermatopathy.

Dermotoxins
Specific substances elaborated by plants, microorganisms or animals that cause damage to the skin; they may be proteins or other specific factors or substances; constituents of spider, jellyfish or other venoms cause dermonecrosis and certain bacteria synthesize dermolytic agents.

Dermotricine
A polypeptide antibiotic mixture obtained from Bacillus brevis. It consists of a mixture of three tyrocidines (60%) and several gramicidins (20%) and is very toxic to blood, liver, kidneys, meninges, and the olfactory apparatus. It is used topically.

Dermatitides, Phototoxic
A nonimmunologic, chemically induced type of photosensitivity producing a sometimes vesiculating dermatitis. It results in hyperpigmentation and desquamation of the light-exposed areas of the skin.

Dermatitides, Photosensitive Contact
A delayed hypersensitivity involving the reaction between sunlight or other radiant energy source and a chemical substance to which the individual has been previously exposed and sensitized. It manifests as a papulovesicular, eczematous, or exudative dermatitis occurring chiefly on the light-exposed areas of the skin.

Dermatitides, Exfoliative
The widespread involvement of the skin by a scaly, erythematous dermatitis occurring either as a secondary or reactive process to an underlying cutaneous disorder (e.g., atopic dermatitis, psoriasis, etc.), or as a primary or idiopathic disease. It is often associated with the loss of hair and nails, hyperkeratosis of the palms and soles, and pruritus. (From Dorland, 27th ed)
