Understanding Other Follicular Cysts of the Skin and Subcutaneous Tissue
Follicular cysts are sac-like growths that form from the hair follicles. While sebaceous cysts are the most common type of follicular cyst, there are other types that can develop in the skin and subcutaneous tissue.
Here are the different types of other follicular cysts:
- Pilar Cysts: Also known as trichilemmal cysts, these cysts form from the outer hair root sheath and are commonly found on the scalp. They tend to be smooth, firm, and round, and can range in size from a few millimeters to several centimeters in diameter.
- Epidermoid Cysts: These cysts form from the cells that make up the outermost layer of skin. They can be found anywhere on the body, but are most commonly seen on the face, neck, and trunk. They tend to be slow-growing, painless, and often have a central punctum or opening.
- Dermoid Cysts: These cysts are rare and form from cells that are present during fetal development. They can contain a variety of tissues, including hair, teeth, and bone. They tend to be slow-growing and painless, and are most commonly found on the face, neck, and upper chest.
Other follicular cysts can also occur, such as steatocystoma multiplex, which is characterized by multiple small cysts that form on the skin, and eruptive vellus hair cysts, which are small, dome-shaped cysts that appear on the chest and limbs.
The treatment for other follicular cysts typically involves surgical removal, as they do not typically go away on their own and can become infected or inflamed. It is important to have any new growths on the skin evaluated by a dermatologist to ensure proper diagnosis and treatment.
In conclusion, while sebaceous cysts are the most common type of follicular cyst, there are other types that can develop in the skin and subcutaneous tissue. Pilar cysts, epidermoid cysts, and dermoid cysts are the most common types of other follicular cysts. If you notice any new growths on your skin, it is important to have them evaluated by a dermatologist to determine the appropriate treatment plan.
