Article Abstract
Background: Ectopic thyroid tissue (ETT) is characterized by the presence of in any location other than its normal anatomic position. Mediastinal ectopic thyroid gland is a rare entity, accounting for 1% of all ETT cases. In this article, we present seven cases with mediastinal ETT over the last 26 years admitted to Stanford hospital.
Case Description: Searching Stanford pathology database for specimens that contained term "ectopic thyroid" between 1996 and 2021, a total of 202 patients were collected. Among those seven were classified as mediastinal ETT. Patients' electronic medical records were reviewed for data collection purposes. The mean age of our seven cases was 54 years on the day of surgery, and four were female. Chest pressure, cough, and neck pain were most reported presenting symptoms. Four of our patients had thyroid stimulating hormone (TSH) checks all within normal limits. All patients in our study had computed tomography (CT) imaging of the chest detecting the mediastinal mass. Histopathology of the mass revealed ectopic thyroid tissue negative for malignancy in all cases.
Conclusions: Ectopic mediastinal thyroid tissue is a rare clinical entity that should be considered in the differential diagnosis of all mediastinal masses as it usually requires different management and treatment.

Thyroid hormones (THs) are essential regulators of metabolism, homeostasis, and development in metazoans. The canonical genomic pathway involves THs binding to nuclear thyroid hormone receptors (NTHRs), which modulate gene expression in vertebrates. In contrast, non-genomic pathways involve THs interacting with membrane-bound or cytoplasmic receptors.

The ectopic intrathyroidal thymus (EIT) is located anywhere in the thyroid gland along the developmental pathway of thymic descent due to thymic migration during embryogenesis. Ultrasonographic findings of papillary thyroid carcinoma (PTC) resemble those of EIT, which is frequently found in children. We comprehensively evaluated the clinical factors associated with EIT to understand its physiological implications and to explore helpful information for clinical discrimination between EIT and PTC.

Multiple endocrine neoplasia type 1 (MEN1) is a rare autosomal dominant hereditary disorder in which patients develop multiple endocrine tumors simultaneously. Among these, primary hyperparathyroidism (PHPT) is the most common and often the earliest manifestation. All patients with MEN1 and hypercalcemia should have surgery, with most patients requiring surgical treatment before the age of 50.

Congenital hypothyroidism (CH) is the most common neonatal endocrine disorder. It is one of the clinical conditions that has benefited most from the introduction of newborn screening 50 years ago, as clinical management has changed and long-term consequences have been significantly reduced. In areas where neonatal screening is active, most affected patients show a clinically normal phenotype and/or only mild symptoms.

Background: The protein belongs to the family and is primarily localized to early endosomes. It regulates the endocytic pathway through its GTPase activity, thereby affecting various aspects such as cell signaling and metabolic regulation. Dysfunction of is closely associated with the progression and deterioration of multiple types of tumors.
