Cysts are common, non-cancerous, fluid-filled lumps that occur on the surface of the skin. They are generally harmless, but may gradually enlarge or become infected if left untreated. There are several different types of cysts that can appear on various parts of the body.
These present as round, bluish-grey lumps that often have a tiny black dot (punctum) plugging the cyst opening centrally. Thick, whitish-yellow smelly material may be expressed from the cysts. Epidermal cysts can occur anywhere, but most frequently affect the trunk, face and neck.
Most pilar cysts occur on the scalp, and present as round, firm skin coloured lumps. Some people may develop multiple pilar cysts all over their scalp. Unlike epidermal cysts, pilar cysts do not have a central punctum.
These often present as multiple small skin-coloured lesions that do not cause any symptoms. They lack a central punctum. Common sites include the upper chest, abdomen and limbs. They contain oily material (sebum), and tend to develop during puberty when the oil glands are most active.
Most cysts do not cause problems and hence can be left alone if they are not bothering you. However, cysts can be removed if they are enlarging, if you find them cosmetically unpleasant or if they get infected.
Cysts can be removed surgically. Our dermatologists are trained in the minimal excision technique, which can result in a smaller and cosmetically more pleasing scar.
Infected cysts are treated with antibiotics and drainage. Once the infection settles, the remnant cyst should be excised to prevent a recurrence of the infection.
Following the diagnosis of cysts, our dermatologists will discuss a personalised treatment plan with you.
