Summary
Double thyroglossal duct cysts, though rare, can occur in children. This case highlights their connection and emphasizes including them in pediatric thyroid cyst diagnoses.
Area of Science:
- Pediatric Surgery
- Developmental Biology
- Head and Neck Pathology
Background:
- Thyroglossal duct cysts are common congenital anomalies in children, typically found along the thyroglossal duct's path.
- These cysts can present anywhere from the tongue base to the sternum.
- The thyroglossal duct normally involutes during embryonic development.
Observation:
- A pediatric patient presented with a rare double thyroglossal duct cyst.
- One cyst was located in the hyoid region, and the second was found within the thyroid gland.
- A permeable tract connected the two cysts.
Findings:
- The presence of a connected double cyst confirms a failure of complete involution of the embryonic thyroglossal duct remnants.
- This case demonstrates an unusual presentation of thyroglossal duct cyst development.
- The findings support a developmental etiology for complex thyroglossal duct cyst formations.
Implications:
- Intrathyroid thyroglossal duct cysts, while uncommon, are a critical consideration in the differential diagnosis of pediatric thyroid cystic lesions.
- Accurate diagnosis is essential for appropriate surgical management and patient outcomes.
- Understanding the embryological basis of these anomalies aids in recognizing rare presentations.

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...

01:29Exocrine Glands: Unicellular and Multicellular Glands
Exocrine glands are classified as unicellular and multicellular. The unicellular glands are scattered single cells, such as goblet cells, found in the mucous membranes of the small and large intestines. On the other hand, multicellular exocrine glands develop as secretory sheets, like the internal lining of the abdomen or chest. Such secretory sheets release their secretions directly into the lumen of these organs. In addition, some multicellular glands have deep-seated secretory units to...
01:20Classification of Epithelial Tissues: Glandular Epithelium
The glandular epithelium is made of one or more epithelial cells modified to synthesize and secrete chemical substances. Glandular epithelia can be classified based on cell number. Unicellular glands have individual secretory cells scattered across the epithelial monolayer. In contrast, multicellular glands consist of a hollow tubular duct attached to the cluster of secretory cells located in the deep pockets.

01:27Goiter
Goiter refers to an abnormal enlargement of the thyroid gland that may appear as a diffuse goiter (uniform enlargement) or nodular (single or multiple nodules). Functionally, it is classified as nontoxic (normal/low hormone levels) or toxic (excess hormone production).PathophysiologyDiffuse thyroid enlargement typically results from prolonged stimulation by thyroid-stimulating hormone (TSH) or TSH-like agents, commonly seen in hypothyroidism or iodine deficiency. In contrast, in hyperthyroid...
00:59The Parathyroid Glands
The two pairs of parathyroid glands embedded within the posterior surface of the thyroid gland are restricted by a dense capsule around them. These glands comprise two distinct cell populations—parathyroid oxyphil and parathyroid principal cells- pivotal in calcium homeostasis.
Oxyphil cells, whose functions remain elusive, emerge during late puberty, adding a layer of complexity to the parathyroid gland's intricacies. In contrast, principal parathyroid cells undertake a vital role by producing...

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...
