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.

col·loid goi·ter

a form of goiter in which the contents of the follicles increase greatly, causing pressure atrophy of the epithelium so that the gelatinous matter predominates in the tumor.

Neoplastic and nonneoplastic lesions are known to be associated with HT like colloid goiter, follicular adenoma, Hurthle cell neoplasm, papillary thyroid carcinoma (PTC), non-Hodgkin's lymphoma (NHL), and follicular carcinoma [38].
Among NNNI lesions, out of total 55 cases of colloid goiter, histopathological correlation done in 20 cases.
The commonest non neoplastic lesion in this study was colloid goiter including diffuse and multinodular goiters which constituted 60% of the thyroid specimens.

The mean serum TSH value of differentiated carcinoma was more than the mean TSH value of colloid goiter.
The histology though showed the features of a nodular colloid goiter. Aspiration was probably carried out from the hyper cellular areas of colloid nodules, which led to overdiagnosis.

FNAC diagnosis of Non-neoplastic lesions were 75(83.33%) cases of which colloid goiter were 67(74.44%) cases, adenomatoid goiter 5(5.56%) case, thyroid cyst 2(2.22%) cases and Hashimoto's thyroiditis 1(1.11%) case.
The distribution of etiology among patients with Overt Hypothyroidism was as follows: Hashimotos thyroiditis in 12(60%), Nodular Goiter in 5(25%), Colloid Goiter in 2(10%), and Lymphocytic thyroiditis in 1(5%).
Out of total of 1135 cases; 528 cases were nodular colloid goiter, 321 were Hashimotos thyroiditis, 72 were papillary thyroid carcinoma, 70 were cystic lesions and 62 were follicular lesions.
Lymphocytic thyroiditis was responsible for the goiter in 13 patients (68%) and 6 others (32%) had colloid goiter. No specific cause for SH could be found in 11 patients (37%).
