What is colloid adenomatous goiter?
Colloid nodules, also known as adenomatous nodules or colloid nodular goiter are benign, noncancerous enlargement of thyroid tissue. Although they may grow large, and there may be more than one, they are not malignant and they will not spread beyond the thyroid gland.
Is adenomatous goiter cancerous?
This study disclosed a high prevalence of thyroid cancer associated with adenomatous goiter, and the results suggest that a considerable number of associated carcinomas remain occult. The detection of calcification in the thyroid gland is one of the surgical indications for patients with adenomatous goiter.
What is adenomatous nodule?
Thyroid adenoma is a benign lesion of the thyroid gland. There are two types of thyroid adenomas, follicular and papillary. Thyroid adenoma usually presents as a solitary thyroid nodule. It is important to exclude malignancies from the differential diagnosis because thyroid carcinoma mimics adenoma.
What is Uninodular goiter?
A goiter simply means an enlarged thyroid. A goiter can either be a simple goiter where the whole thyroid is bigger than normal or a multinodular goiter where there are multiple nodules. Multinodular goiters can be either a toxic multinodular goiter (i.e. makes too much thyroid hormone and causes hyperthyroidism.
Is colloid goiter normal?
Colloid goitres are a common, benign lesion of the thyroid gland, that involve a diffuse or nodular pattern.
What does adenomatous mean?
What is an adenoma (adenomatous polyp)? An adenoma is a polyp made up of tissue that looks much like the normal lining of your colon, although it is different in several important ways when it is looked at under the microscope. In some cases, a cancer can start in the adenoma.
What is the difference between a nodule and an adenoma?
This practice is imprecise because adenoma implies a specific benign new tissue growth with a glandlike cellular structure, whereas a nodule could as well be a cyst, carcinoma, lobule of normal tissue, or other focal lesion different from the normal gland.
Is goiter a hyperthyroid or hypothyroid?
A goiter can occur in a gland that is producing too much hormone (hyperthyroidism), too little hormone (hypothyroidism), or the correct amount of hormone (euthyroidism). A goiter indicates there is a condition present which is causing the thyroid to grow abnormally.
Can a multinodular goiter become cancerous?
Multinodular goiters (MNG) have recently been shown to have an incidence of cancer that approaches that of solitary thyroid nodule. However, fine needle aspiration (FNA) of a MNG is limited due to the presence of multiple nodules.
Is there such a thing as an adenomatous goiter?
A nodule of the thyroid gland may be defined as a more or less encapsulated mass of thyroid tissue which may or may not be different from the surrounding thyroid tissue. The term “nodular goiter” is used frequently by pathologists and surgeons as a synonym for adenomatous goiter.
Where is the thyroid gland located in goiter?
Goiter is a condition in which the thyroid gland grows larger. The thyroid gland is a small, butterfly-shaped gland located in the neck, below the Adam’s apple. The thyroid gland produces the hormones thyroxine (also called T4) and triiodothyronine (also called T3).
Can a person with goiter have hyperthyroidism?
Some people who have a goiter may also have hyperthyroidism, or overactive thyroid. Symptoms of hyperthyroidism can include: Some people with goiter may also have hypothyroidism, or underactive thyroid. Symptoms of hypothyroidism can include:
