skin tag(skin tag)
Polypoid outgrowth of both epidermis and dermal fibrovascular tissue.
the outer covering and largest organ of the body. It serves as a protective barrier against microorganisms, helps shield delicate tissues underneath from mechanical and other injuries, insulates against heat and cold, and helps eliminate body wastes. It guards against ultraviolet radiation by producing a protective pigment and it helps produce vitamin D. Its sense receptors detect pain, cold, heat, touch and pressure.
The skin consists of an outer cellular, avascular epidermis, and an inner fibrous corium (dermis, true skin) resting upon a hypodermis of fat and panniculus muscle.
skin-associated lymphoid tissues (SALT)
see skin-associated lymphoid tissue.
removal of a small section of skin for histopathological examination. See also keyes punch.
include squamous cell carcinoma, papilloma and fibropapilloma, intracutaneous cornifying epithelioma (keratoacanthoma), basal cell tumors and tumors of the adnexa, perianal gland and hair follicles.
congenital absence of skin

see subcutaneous emphysema.
skin fold thickness
a measure of obesity in humans but not a valid indicator in dogs or cats as the skin lifts off the subcutaneous tissue.
death of tissue and usually involves dermis, epidermis and subcutaneous tissue, e.g. severe saddle galls, heat burns, chemical burns, Claviceps purpurea poisoning. The affected area is cold and bluish in color. This changes to black and the area begins to lift at the edges and to dry out.

skin tenting test
a fold of skin is picked up and then quickly let go. The amount that it will stretch is an indication of its extensibility. The speed with which it returns to a normal position is determined by the degree of hydration of the skin and subcutaneous tissue and the amount of fat in the subcutaneous tissue, e.g. in an animal that is 10 to 12% dehydrated the skin fold will not disappear until 20 to 45 seconds have elapsed.
application or intradermal injection of a substance to the skin to test the body's reaction to it. Such a test detects an animal's sensitivity to such allergens as dust and pollen, or to preparations of microorganisms believed to be the cause of a disorder.
There are several types of skin tests, including the patch test, the scratch test, and the intradermal test.
