Excrescence
|
|
ExcrescenceAn abnormal outgrowth as, for example, a wart.
RELATED TERMS--------------------------------------
Abnormal
Not normal. Deviating from the usual structure, position, condition, or behavior. In referring to a growth, abnormal may mean that it is cancerous or premalignant (likely to become cancer).
Wart
A small, hard, abnormal growth of the skin or mucous membranes caused by a virus.
SIMILAR TERMS--------------------------------------
Excrete
To get rid of waste from the body.
PREVIOUS AND NEXT TERMS--------------------------------------
Excimer laser
A laser that emits very concentrated light in the ultraviolet (UV) region of the spectrum.
Excision
1. Surgical removal, as in the excision of a tumor. 2. The removal as if by surgery, as in base excision repair.
Excisional
Pertaining to the act of excision, of removal by surgery. An excisional biopsy is one in which the lesion is removed by the biopsy.
Excisional biopsy
A biopsy in which an entire biopsy in which an entire lesion, is removed. A excisional biopsy is in contrast to an incisional biopsy in which only a sample of tissue is cut into (incised) and removed.
Exclamation point hair
Exclamation point hair is a key diagnostic finding in a disorder called alopecia areata. Alopecia areata is patchy baldness (alopecia means baldness and areata means occurring in patches) which typically begins with patchy hair loss on the scalp and sometimes progresses to complete baldness and even loss of body hair. The hair loss tends to be rather rapid and asymmetrical and is different than male pattern baldness.Alopecia areata affects both males and females. It tends to occur most often in children and young adults but older individuals can also be affected.The most common pattern of alopecia areata is one or more spots of hair loss on the scalp. There is also a form with more generalized thinning. When all of the scalp hair is lost, it is called alopecia totalis. Loss of all of the hairs on the body is called alopecia universalis.
Excrescence
Exemestane
An oral antiestrogen. Exemestane inhibits the enzyme aromatase in the adrenal glands that produces the estrogens (estradiol and estrone) and thereby lowers their levels.
Exercise test
A test (sometimes called the treadmill test or exercise treadmill test) in which a continuous electrocardiogram (ECG or EKG) recording of the heart is made as the patient performs increasing levels of exercise on the treadmill which is tilted to produce the effect of going up a small hill. The patient can stop the test at any time, if necessary. Afterwards the patient has heart and blood pressure checked. There is very little risk in taking the test in healthy persons -- no more than if a person walks fast or jogs up a big hill. Medical professionals should be present in case something unusual happens during the test. The exercise test screens for the presence of narrowed coronary arteries that can limit the supply of oxygenated blood to the heart muscle during exercise. The test also detects abnormal heart rhythms (arrhythmias).
Exercise treadmill
Exercise on a treadmill, a machine with a moving strip on which one walks without moving forward. A treadmill was originally a wide wheel turned by the weight of people climbing on steps around its edge, used in the past to provide power for machines or as a punishment in prisons.
Exercise treadmill test
A test (sometimes simply called a treadmill test or exercise test) in which a continuous electrocardiogram (ECG or EKG) recording of the heart is made as the patient performs increasing levels of exercise on the treadmill which is tilted to produce the effect of going up a small hill. The patient can stop the test at any time, if necessary. Afterwards the patient has heart and blood pressure checked.
Exercise, isometric
Exercise involving muscular contractions without movement of the involved parts of the body. Isometric exercise is one method of muscular exercise. In contrast, isotonic exercise occurs when a contracting muscle shortens against a constant load, as when lifting a weight.
