What are the causes of cysts in earlobes?

* Sebaceous cysts: These are the most common type of cyst and are caused by a blockage of the sebaceous glands. Sebaceous glands are small oil-producing glands that are located in the skin. When these glands become blocked, oil can build up and form a cyst.

* Epidermoid cysts: These cysts are caused by a growth of skin cells that becomes trapped under the skin. Epidermoid cysts are often found on the face, neck, and back, but they can also occur on the earlobes.

* Dermoid cysts: These cysts are rare and are caused by a defect in the development of the embryo. Dermoid cysts can contain a variety of tissues, including skin, hair, and teeth.

* Hyaline cysts: These cysts are filled with a clear fluid and are often found on the earlobes of older adults. Hyaline cysts are not typically painful and do not require treatment.
