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.

Figure 1 shows pseudopapillae formation in adenomatous goiter. Figure 2 shows lymphocytes with Hurthle cells in Hashimoto's thyroiditis.
Out of 16 cases of adenomatous goiter, 4 cases were confirmed by HPE, while 2 cases were incorrect, in which final diagnosis was follicular adenoma.
Adenomatous goiter 82 (78.11%) was the commonest non-neoplastic lesion, follicular adenoma 10 (9.52%) was the commonest benign neoplastic lesion whereas papillary carcinoma 4 (3.81%) was the commonest malignant lesion.
The commonest non neoplastic lesion in this study was adenomatous goiter which is nearly same to the other studies conducted by Mirzakarimov et al13 and Rehman et al17 71.96% and 92.05% respectively, whereas Sushel et al8 and Misiakos et al14 show a relatively lower incidence i.e.
Non-Neoplastic lesions included colloid goiter, adenomatous goiter, multi nodular goiter, thyroid cysts and Hashimoto's thyroiditis, while in Neoplastic category we found the cases of Follicular Adenoma, Follicular Neoplasm, Papillary carcinoma and Anaplastic carcinoma.
In our study, 9 out of 16 cases were diagnosed as suspicious but actually came out to be benign on HPE (5 were adenomatous goiter and 4 follicular adenoma).
