Summary
Rare thyroid malignancies can mimic aggressive cancers like anaplastic thyroid cancer (ATC). Accurate diagnosis requires detailed histopathology and molecular testing for these unusual tumors.
Area of Science:
- Oncology
- Pathology
- Genetics
Background:
- Thyroid gland rare pathologies pose diagnostic challenges.
- These unusual malignancies can mimic aggressive cancers.
Purpose of the Study:
- To report patients with unusual thyroid malignancies.
- To highlight diagnostic challenges in differentiating rare tumors from anaplastic thyroid cancer (ATC).
Main Methods:
- Retrospective case series analysis.
- Histopathologic and molecular evaluation of thyroid tumors.
Main Results:
- Eight patients presented with aggressive thyroid tumors resembling ATC.
- Diagnoses included Adamantinoma-like Ewing sarcoma (ALES), osteosarcoma, angiosarcoma, high-grade sarcoma with PRMT8-NTRK fusion, and mucoepidermoid carcinoma (MEC) variants.
- Specific molecular findings like EWSR1-FLI1 rearrangement and PRMT8-NTRK fusion were identified.
Conclusions:
- Several rare thyroid malignancies present similarly to ATC.
- Meticulous histopathologic and molecular assessment is crucial for accurate diagnosis.
- Distinguishing these rare tumors is essential for appropriate patient management.

01:23The Thyroid Gland
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...

01:25Hyperthyroidism I: Introduction
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...
01:27Hyperthyroidism II: Pathophysiology
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 receptors...
01:28Graves' Disease I: Introduction
Graves' disease is an autoimmune disorder that causes hyperthyroidism, or overactivity of the thyroid gland. It results from autoantibodies called thyroid-stimulating immunoglobulins (TSIs), which bind to thyroid-stimulating hormone (TSH) receptors, leading to overstimulation of hormone production and a hypermetabolic state.EtiologyAlthough considered idiopathic, Graves’ disease has well-established contributing factors. There is a strong genetic component, with increased prevalence in...
01:24Graves Disease II: Pathophysiology
Graves’ disease is an autoimmune disorder characterized by the production of thyroid-stimulating immunoglobulins (TSI) that activate TSH receptors, leading to excessive synthesis and release of thyroid hormones (T3 and T4) and resulting in hyperthyroidism.Among all causes of hyperthyroidism, Graves’ disease is the most common and can happen at any age, though it is more frequent in women. It produces a hypermetabolic state with features such as weight loss, tachycardia, tremor, and heat...
01:23Hypothyroidism II: Pathophysiology
Hypothyroidism is a disorder characterized by insufficient production of thyroid hormones, which regulate metabolism, energy balance, and multiple organ systems.TypesHypothyroidism is classified based on the level of dysfunction. Primary hypothyroidism results from intrinsic thyroid gland dysfunction, causing reduced hormone production despite normal or increased stimulation. Secondary hypothyroidism arises from inadequate thyroid-stimulating hormone (TSH) secretion by the pituitary. Tertiary...
