Summary
Epidermal inclusion cysts (EIC) are rare in the thyroid but can cause symptoms. A case report details a benign thyroid cyst diagnosed as EIC, confirming its rare occurrence.
Area of Science:
- Endocrinology
- Pathology
Background:
- Epidermal inclusion cysts (EIC) are typically benign skin, ovarian, or testicular lesions.
- EIC in the thyroid gland is an exceptionally rare clinical presentation.
Observation:
- A 57-year-old male with nontoxic uninodular goiter presented with dysphonia and dysphagia.
- Ultrasound-guided fine needle aspiration of a thyroid nodule revealed an epidermal cyst.
Findings:
- Surgical pathology confirmed the benign thyroid cyst as an EIC.
- This case highlights the rare occurrence of EIC within the thyroid gland.
Implications:
- EIC should be considered in the differential diagnosis of rare thyroid nodules.
- This finding contributes to understanding the rare manifestations of EIC in endocrine organs.

01:23The Thyroid Gland
6.1K
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...

01:20Synthesis and Regulation of Thyroid Hormones
6.6K
Low blood levels of the thyroid hormones — triiodothyronine (T3) and thyroxine (T4) — signal the hypothalamus to release the thyrotropin-releasing hormone (TRH). TRH then reaches the pituitary gland and stimulates the release of thyroid-stimulating hormone(TSH) into the bloodstream.
Upon reaching the thyroid gland, TSH stimulates the follicular cells' active uptake of iodide ions from the blood. The ions diffuse to the apical surface of the cells and are oxidized to iodine. The...

00:59The Parathyroid Glands
3.9K
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...

01:21Accessory Structures of the Skin: Sebaceous Glands
3.4K
A sebaceous gland is a type of oil gland found almost all over the skin ( except palms and soles) and helps lubricate and waterproof the skin and hair. Most sebaceous glands are associated with hair follicles. They generate and excrete sebum, a mixture of lipids, onto the skin surface, thereby naturally lubricating the dry and dead layer of keratinized cells of the stratum corneum, keeping it pliable.
These glands that produce the oils on the skin and hair are holocrine glands. The mature...

Dermis
The dermis might be considered the "core" of the integumentary system, as distinct from the epidermis and hypodermis. It contains blood and lymph vessels, nerves, and other structures, such as hair follicles and sweat glands. The dermis is made of two layers of connective tissue that comprise an interconnected mesh of elastin and collagenous fibers, produced by fibroblasts.
Papillary Layer
The papillary layer is made of loose, areolar connective tissue, which means the collagen...

01:30Skin Cancer
5.4K
Skin cancer is a type of cancer that occurs when there is an abnormal growth of skin cells, usually triggered by damage to the DNA within the skin cells. It is primarily caused by exposure to ultraviolet (UV) radiation from the sun or artificial sources like tanning beds. Skin cancer is the most common type of cancer worldwide, and its incidence continues to rise.
