Dermoid cysts contain various skin elements, such as sweat and sebaceous glands and hair. All dermoid cysts stem from cells deposited during fetal development. Some dermoid cysts do not show any symptoms and require no intervention. Others are visible or cause pain and pressure; these may require surgical intervention.
Dermoid cysts present differently depending on their location. They are essentially skin cells trapped in other tissues, growing during fetal development. Just like skin, these trapped cells shed and produce oil. As more cells develop, the cyst grows larger. When dermoid cysts are close to the surface, they usually form lumps and are painless.
