goiter

 [goi´ter]
enlargement of the thyroid gland, causing a swelling in the front part of the neck; called also struma. adj., adj goit´rous. If there is evidence of pressure against the throat, or the possibility of a malignancy, the goiter may be removed surgically. Simple endemic goiter is usually caused by lack of iodine in the diet. In graves' disease, goiter is accompanied by excessive thyroid hormones in the blood and symptoms of hyperthyroidism.
aberrant goiter goiter of a supernumerary thyroid gland.
adenomatous goiter that caused by adenoma or multiple colloid nodules of the thyroid gland.
Basedow goiter a colloid goiter that has become hyperfunctioning after administration of iodine.
colloid goiter one that is large and soft and has distended spaces filled with colloid.
cystic goiter one with cysts formed by mucoid or colloid degeneration.
diffuse toxic goiter exophthalmic goiter.
endemic goiter goiter occurring widely in a geographic region where the food or water is deficient in iodine. Treatment consists of iodine replacement; although this will not cure the condition, it can stop it from enlarging, and iodine administered in advance will prevent development of goiter.
exophthalmic goiter any type accompanied by exophthalmos.
fibrous goiter goiter in which the thyroid capsule and stroma are hyperplastic.
follicular goiter parenchymatous goiter.
intrathoracic goiter one with part of the enlarged gland in the thoracic cavity.
iodide goiter that occurring in reaction to iodides at high concentrations, due to inhibition of iodide organification.
multinodular goiter one with circumscribed nodules within the gland.
nontoxic goiter that occurring sporadically and not associated with hyperthyroidism or hypothyroidism.
parenchymatous goiter one with increase in follicles and proliferation of epithelium.
perivascular goiter one that surrounds a large blood vessel.
retrovascular goiter one with processes behind a large blood vessel.
substernal goiter one whose lower part lies beneath the sternum.
suffocative goiter one that causes dyspnea due to pressure.
toxic multinodular goiter hyperthyroidism arising in a multinodular goiter, usually of long standing.
vascular goiter one due chiefly to dilatation of the blood vessels of the thyroid gland.

GOITER
Enlargement of the thyroid gland . An enlarged thyroid gland may be caused by thyroiditis, benign thyroid nodules, malignancy, iodine deficiency, or any condition that causes hyperfunction or hypofunction of the gland. Synonym: struma See: illustration

aberrant goiter

A supernumerary goiter.

acute goiter

A goiter that grows rapidly.

adenomatous goiter

An outdated term for multinodular goiter.

colloid goiter

A goiter in which there is a great increase of the follicular contents.

congenital goiter

A goiter present at birth.

cystic goiter

A goiter in which a cyst or cysts are formed, possibly resulting from the degeneration of tissue or liquefaction within an adenoma.

diffuse goiter

A goiter in which the thyroid tissue is diffuse, in contrast to its nodular form as in adenomatous goiter.

diving goiter

A movable goiter, located either below or above the sternal notch.

endemic goiter

Goiter development in certain geographic localities, esp. where the iodine content in food and water is deficient. Goiters are more prevalent in fresh water and lake areas and less so on the seacoast, owing to the lack of iodine in fresh water. The treatment consists of iodine taken orally or in iodized salt.

exophthalmic goiter

Goiter associated with exopthalmos, as in Graves ophthalmopathy.
Synonym: thyroid cachexia

fibrous goiter

A goiter with a hyperplastic capsule.

intrathoracic goiter

A goiter in which a portion of the thyroid tissue lies within the thoracic cavity.

lingual goiter

The abnormal finding of thyroid glandular tissue within the tongue.

multinodular goiter

A goiter having many circumscribed nodules.

nodular goiter

A goiter that contains nodules.

parenchymatous goiter

A usually diffuse goiter characterized by multiplication of cells lining the follicles or alveoli. Colloid is usually reduced and the follicular cavities assume various sizes and are often obliterated by the infoldings of their walls. Fibrous tissue may increase markedly. The iodine content of the gland is low.

perivascular goiter

A goiter surrounding a large blood vessel.

retrovascular goiter

A goiter that develops behind a large blood vessel.

simple goiter

A goiter unaccompanied by constitutional symptoms.

substernal goiter

An enlargement of the lower part of the thyroid isthmus.

suffocative goiter

A goiter that causes shortness of breath owing to pressure.

toxic goiter

An exophthalmic goiter or a goiter in which there is an excessive production of the thyroid hormone.

vascular goiter

A goiter due to distention of the blood vessels of the thyroid gland.
