How is ectopic thyroid tissue diagnosed?

Scintigraphy, using Tc-99m, I-131, or I-123, is the most important diagnostic tool to detect ectopic thyroid tissue and shows the absence or presence of thyroid in its normal location. Thyroid scan can also unmask additional sites of thyroid tissue.

What is ectopic thyroid?

Ectopic thyroid is defined as any thyroid tissue not located in its usual position (i.e., anterior and lateral to the second, third, and fourth tracheal rings). During development, the thyroid gland descends from the foramen cecum at the base of the tongue to its location at the front of the trachea.

Is ectopic thyroid tissue cancerous?

Thyroid cancer arising from ectopic tissue remains a rare entity. The possibility of an ectopic thyroid cancer in the setting of a normal thyroid gland should be considered as a differential diagnosis in cases of an identified neck mass.

What is the treatment for ectopic thyroid tissue?

Surgery seems to be the most appropriate treatment for patients with ectopic thyroid tissue showing clinical signs of upper airway obstruction or when the lesion shows signs of infection or malignant degeneration.

How common is ectopic thyroid?

The prevalence of ectopic thyroid gland is one case for every 100000 to 300000 of healthy individuals, but it reportedly occurs in one of 4000 to 8000 patients who have thyroid disease.

What causes inflammation of the thyroid?

An inflamed thyroid may occur in response to a viral infection (viral thyroiditis) or a bacterial infection (bacterial thyroiditis), following radiation, or in response to certain medications. Your doctor will determine the cause of your thyroiditis and will then treat the condition as needed.

What is Struma Ovarii?

Struma ovarii is a specialized or monodermal teratoma predominantly composed of mature thyroid tissue [1]. Thyroid tissue must comprise more than 50 percent of the overall tissue to be classified as a struma ovarii. Struma ovarii accounts for approximately 5 percent of all ovarian teratomas [2-4].

What causes thyroid tissue?

Certain factors increase your risk of thyroid cancer, such as a family history of thyroid or other endocrine cancers and having a history of radiation exposure from medical therapy or from nuclear fallout. Iodine deficiency. Lack of iodine in your diet can sometimes cause your thyroid gland to develop thyroid nodules.

What is thyroid hypoplasia?

Thyroid hypoplasia is a form of thyroid dysgenesis (see this term) characterized by incomplete development of the thyroid gland that results in primary congenital hypothyroidism (see this term), a permanent thyroid deficiency that is present from birth. Epidemiology. Prevalence is estimated at around 1/28,000.

How do you reduce inflammation of the thyroid?

How Can We Decrease Inflammation?

1. Consume adequate nutrients from foods and supplements that decrease inflammation in the thyroid.
2. Strengthen gut health.
3. Lower stress.
4. Eat a nutrient dense, low-carb diet.
5. Get proper thyroid medication.
6. Eliminate or greatly reduce thyroid inflammation triggers.

Are there any cases of ectopic thyroid tissue?

The ectopic thyroid tissue (ETT) is a rare phenomenon with an overall prevalence of 1 in 100,000-300,000 in general population, and 1 in 4,000-8,000 in patients with a pre-existing thyroid disorder [1, 2].

What is the probability of ectopic thyroid carcinoma?

The probability of carcinoma arising in ectopic thyroid tissue in thyroglossal duct remnant is reported in the literature as less than 1%, involving in almost in all cases papillary carcinomas, as with our patient (7).

Can a benign ectopic thyroid be a primary mass?

Rarely, aberrant, benign ectopic thyroid presents as a primary mass. Case report: We present a 35‐year‐old female who presented for removal of a lifelong posterior lateral neck nodule. Results: Histologic examination and immunohistochemical studies confirmed the presence of aberrant, benign ectopic thyroid tissue.

Can a thyroglossal ectopic thyroid carcinoma cause lymph node involvement?

Thyroglossal ectopic papillary thyroid carcinomas are also reported as being associated with foci of papillary thyroid carcinoma in the orthotopic thyroid gland, while lymph node involvement is estimated to be 7–8% (8). In our case, the eutopic thyroid gland was normal and there was no lymph node involvement.
