| cervical erosion | A partial or complete absence of the mucosa which normally covers the cervix. These lesions or ulcers, may occur as the result of trauma (for example intercourse, tampon insertion), infection or chemicals (for example spermicidal creams or foams, douches). There appears to be a increased risk of cervical erosion with vaginal use of chemical agents or those with multiple sex partners. Symptoms of cervical erosion include vaginal bleeding and post-coital bleeding. Often there may be no symptoms at all. Erosions or ulcerations of the cervix are generally noted on the pelvic examination and can be an indicator of cervical cancer. For this reason a PAP smear will be recommended. most cervical erosions will heal spontaneously without intervention. (27 Sep 1997) |

| tooth erosion | Progressive loss of the hard substance of a tooth by chemical processes that do not involve bacterial action. (12 Dec 1998) |
| erosion | 1. An eating away, destruction of the surface of a tissue, material or structure. 2. Progressive loss of the hard substance of a tooth by chemical processes that do not involve bacterial action. See: abrasion. 3.

| allergy skin test | Test done on the skin to identify the allergy substance (allergen) triggering the allergic reaction. A small amount of the suspected allergy substance is placed on the skin.

| alligator skin | <dermatology> A group of cutaneous disorders characterised by increased or aberrant keratinisation, resulting in noninflammatory scaling of the skin. Many different metaphors have been used to describe the appearance and texture of the skin in the various types and stages of ichthyosis, for example alligator, collodion, crocodile, fish and porcupine skin. most ichthyoses are genetically determined, while some may be acquired and develop in association with various systemic diseases or be a prominent feature in certain genetic syndromes. The term is commonly used alone to refer to i. Vulgaris. (18 Nov 1997) |
| appendages of skin | The hairs, nails, and sweat, sebaceous, and mammary glands. (05 Mar 2000) |
| aspergillus antigen skin test | <investigation> An antigen, prepared from aspergillus, is injected into the skin. In 48 to 72 hours the site is read as positive or negative. A positive skin test (inflammation at the test site) indicates prior exposure to aspergillus and therefore a risk for developing aspergillosis. (27 Sep 1997) |
| bronzed skin | The dark skin in Addison's disease. (05 Mar 2000) |
| calipers, skin | Calipers are instruments used to measure the diameter of an object. (The word calipers is a corruption of caliber ).

| cancer, skin | Cancer of the outer surface of the body. The most common cancer in the U.S. There are many types of skin cancer. Ultraviolet light from sunlight is the main cause of skin cancer. Unexplained changes in the appearance of the skin, lasting longer than 2 weeks, should be evaluated by a doctor. The cure rate for skin cancer could be 100% if all skin cancers were brought to a doctor's attention before they had a chance to spread. (12 Dec 1998) |
| carcinoma, skin appendage | A malignant tumour of the skin appendages, which include the hair, nails, sebaceous glands, sweat glands, and the mammary glands. (12 Dec 1998) |
