Sebaceous cysts are small, benign growths that develop beneath the skin. This medical term is spelled as Sɪˈbeɪʃəs sɪsts, with the first syllable pronounced as "sih" and the second as "bay". The word "sebaceous" refers to the glands that produce sebum, an oily substance that helps to moisturize and protect the skin. Meanwhile, "cysts" are sac-like structures that can form when cells accumulate and form a lump. Sebaceous cysts are typically harmless, but they can become infected or inflamed and require medical attention.
Sebaceous cysts are small, benign, encapsulated growths that form beneath the skin surface. These cysts develop when the sebaceous gland, which produces an oily substance called sebum, becomes obstructed or damaged. Sebaceous cysts can occur anywhere on the body where hair follicles are present, but they are most commonly found on the scalp, face, neck, and back.
The most noticeable characteristic of sebaceous cysts is their appearance as small, round or dome-shaped bumps under the skin. They are typically firm to the touch and have a white or yellowish coloration. The cysts may remain small and asymptomatic for a long time, but they can grow larger over time, causing discomfort or cosmetic concern. In some cases, the cysts may become inflamed or infected, leading to redness, pain, tenderness, and the formation of a pus-filled abscess.
The exact cause of sebaceous cysts is often unclear, but they may develop due to factors such as hormonal imbalances, excessive production of sebum, genetic predisposition, or trauma to the skin. While sebaceous cysts are generally harmless, they can be treated if they become problematic. Treatment options include draining the cyst, removing it surgically, or administering corticosteroid injections to reduce inflammation and stimulate cyst shrinkage.
It is important to note that sebaceous cysts should not be squeezed, popped, or drained at home, as this can lead to infection, scarring, and potential recurrence. Consulting a healthcare professional for proper diagnosis and management is recommended.
The word "sebaceous" has its roots in Latin. It comes from the Latin word "sebaceus", which means "greasy" or "tallowy".
The term "cysts" originates from the Greek word "kystis", meaning "bladder" or "sac". In medical terminology, a cyst refers to an abnormal sac-like structure that can contain fluid, air, or other substances.
Therefore, "sebaceous cysts" are cysts that develop from the sebaceous glands, which are responsible for producing an oily substance called sebum that helps lubricate the skin and hair. These cysts typically form when the ducts of the sebaceous glands become blocked, leading to the build-up of sebum.
