| skin tag | A polypoid outgrowth of both epidermis and dermal fibrovascular tissue, common terminology for any small benign cutaneous lesion. Synonym: acrochordon, fibroepithelial polyp, fibroma molle, senile fibroma, soft wart. (05 Mar 2000) |
|---|---|
| skin tags | <dermatology> A small outgrowth of epidermal and dermal tissue that may be pedunculated, smooth or irregular, flesh-coloured and benign. Occur most often on the eyelids, neck and axillae, but may be seen almost anywhere on the skin. Most do not require treatment unless they are cosmetically displeasing. (27 Sep 1997) |
| affinity tag | <biochemistry, molecular biology> A short amino acid sequence, usually engineered onto the N- or C-terminus of a protein, to make its purification easier. (14 Nov 1997) |
|---|---|
| preauricular tag | Common minor anomaly, a rudimentary tag of ear tissue, often containing a core cartilage, usually located just in front of the ear (auricle). Therefore also called preauricular tag. (12 Dec 1998) |
| sentinel tag | Projecting edematous skin at the lower end of an anal fissure. (05 Mar 2000) |

| tag, ear | Common minor anomaly, a rudimentary tag of ear tissue, often containing a core cartilage, usually located just in front of the ear (auricle). Therefore, also called preauricular tag. The presence of 2 or more minor anomalies in a child increases the probability that the child has a major malformation. (12 Dec 1998) |

| abscess, skin | Medical term for a common boil. (12 Dec 1998) |
| 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. The skin is then gently scratched through the small drop with a special sterile needle. If the skin reddens and, more importantly, swells, then allergy to that substance is probable. (12 Dec 1998) |
| 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 ).
