EPIDERMAL CYST Meaning and
Definition
-
An epidermal cyst, also known as a sebaceous cyst or epidermoid cyst, is a benign cystic swelling that originates from the epidermal layer of the skin. It typically forms when the epidermal cells within a hair follicle become trapped, leading to the accumulation of keratin, a proteinaceous substance, within a closed sac or cavity.
Epidermal cysts are usually painless, slow-growing, and can occur in any part of the body, but are commonly found on the face, neck, back, or genitals. They may vary in size, ranging from a few millimeters to several centimeters in diameter, and may remain stable or gradually increase in size over time.
These cysts often present as round, firm, smooth, and mobile bumps beneath the skin, with a central opening or punctum. The punctum serves as an outlet for the thick, yellowish-white, creamy material called sebaceous material or keratin that may be expressed from the cyst when pressure is applied. Despite being benign, at times, the cysts may become infected, inflamed, or cause discomfort due to pressure on surrounding structures.
Epidermal cysts can be diagnosed through clinical examination by a healthcare professional. Although they may resolve on their own, treatment options include incision and drainage, complete excision, or minimal excision techniques. It is essential to seek medical attention if the cyst becomes painful, infected, rapidly growing, or shows other concerning features to rule out any serious underlying conditions.

Etymology of EPIDERMAL CYST
The word "epidermal" is derived from the Greek words "epi", meaning "upon" or "over", and "derma", meaning "skin". The term "epidermal" is used to describe anything related to or located upon the outermost layer of the skin, known as the epidermis.
The word "cyst" originates from the Latin word "cystis", which denotes a bladder or a sac. It was later borrowed from Latin into Greek as "kustis". In medical terminology, a "cyst" refers to an abnormal sac-like structure filled with fluid, semi-solid material, or gas, which can occur in various parts of the body.
When combined, "epidermal cyst" refers to a cyst that develops within the epidermis or just underneath it.
