A sebaceous adenoma is a noncancerous tumor of an oil-producing gland in the skin.
Information
A sebaceous adenoma is a small bump. There is most often only one, and it is usually found on the face, scalp, belly, back, or chest. It may be a sign of a serious internal disease.
If you have several small bumps of the sebaceous glands, this is called sebaceous hyperplasia. Such bumps are harmless in most cases, and often found on the face. They are not a sign of serious disease. They are more common with age. They may be treated if you do not like how they look.

Hair follicle sebaceous gland - illustration
Each pore on the surface of the skin is an opening to a canal called a follicle. The follicle also contains a hair and an oil gland (sebaceous gland). The oil gland helps remove old skin cells, keeps the skin lubricated, and prevents drying of tissues.
