Skin cyst

A fluid-filled lump directly below the skin is a skin cyst. It can go away on its own and is usually harmless.

It is frequently challenging to determine whether a lump requires medical attention and whether it is a cyst. Therefore, if you have any swelling, you should visit a doctor.

Sometimes cysts are mistaken for boils or skin abscesses.

Skin cyst types

One of the primary forms, epidermoid cysts, is often seen on the face, neck, chest, shoulders, or skin surrounding the genitalia.

They primarily affect young and middle-aged adults and are more prevalent in those with acne. They typically do not run in families.

Pilar cysts are cysts that develop around hair follicles. They frequently appear on the scalp.

Middle-aged persons, particularly women, are frequently affected by pilar cysts. They run in families, in contrast to epidermoid cysts.

Chalazion or meibomian cysts are terms used to describe cysts that develop on the eyelid.

How do cysts develop?

Keratin is a protein in the skin responsible for the strength and flexibility of the skin. These cells typically rise to the skin’s surface as they begin to degrade so the skin can shed them

Skin cyst types
However, the cells occasionally penetrate the skin more deeply and grow in number, forming a sac.

They release keratin into the sac’s center, forming a thick, yellow sludge. If the cyst ruptures, this can ooze out.

Anyone can acquire a skin cyst, but those who have gone through puberty, have an acne history or have had skin injuries are more prone to do so.

Skin cysts cannot spread to others.

Self-care in the event of a skin cyst

Cysts are typically not harmful. Small cysts that pose no threat should be left alone.

A warm towel applied to the skin will promote the cyst’s healing and lessen swelling. Refrain from trying to rupture the cyst.
