Summary
Papillary carcinoma is extremely rare in non-lingual median aberrant thyroid tissue, typically found below the hyoid bone. This case highlights the importance of considering ectopic thyroid tissue as a primary site for malignancy.
Area of Science:
- Endocrinology
- Oncology
- Surgical Pathology
Background:
- Median ectopic thyroid is a rare congenital anomaly, with incomplete descent leading to non-lingual aberrant thyroid tissue usually located in the infrahyoid region.
- Malignant transformation within ectopic thyroid tissue is exceptionally uncommon, posing diagnostic challenges.
Observation:
- This report details an extremely rare case of papillary carcinoma arising in non-lingual median aberrant thyroid tissue in a 25-year-old female.
- The tumor was located in the infrahyoid region, consistent with incomplete descent of thyroid tissue.
Findings:
- Histopathological examination confirmed papillary carcinoma within the ectopic thyroid tissue.
- The study discusses the differential diagnosis between primary carcinoma in ectopic thyroid and metastatic disease from an occult primary thyroid carcinoma.
Implications:
- This case underscores the need to consider ectopic thyroid tissue as a potential primary site for thyroid cancer, even in rare locations.
- Accurate differentiation between primary ectopic thyroid carcinoma and metastatic disease is crucial for appropriate patient management and treatment planning.

18
Hyperthyroidism is a hypermetabolic state caused by elevated levels of thyroid hormones, triiodothyronine (T3) and thyroxine (T4). It results from dysregulation at the thyroid, pituitary, or immune system level and affects multiple organ systems.PathophysiologyThe most common cause of hyperthyroidism is Graves’ disease, an autoimmune disorder in which antibodies, specifically thyroid-stimulating antibodies (TSAb), a subtype of TSH receptor antibodies (TRAb), bind to and activate TSH...

01:25Hyperthyroidism I: Introduction
23
Hyperthyroidism is a type of thyrotoxicosis characterized by the thyroid gland's overproduction of the thyroid hormones triiodothyronine (T3) and thyroxine (T4). This hormone excess increases the basal metabolic rate and enhances sensitivity to catecholamines.DiagnosisDiagnosis is based on clinical features and biochemical testing. It typically shows suppressed thyroid-stimulating hormone (TSH) levels below 0.4 mIU/L, with elevated free T3 and/or T4. Additional tests, including thyroid...

01:23The Thyroid Gland
6.9K
The thyroid gland is a small, butterfly-shaped gland located in the neck and covers the anterior surface of the trachea. The gland has two lateral lobes connected by a thin tissue mass called the isthmus. Internally, each lobe comprises many small spherical structures known as thyroid follicles, surrounded by a network of blood vessels.
The follicles have a central cavity lined by simple cuboidal to squamous epithelial cells called follicular cells. These cells produce the glycoprotein...
