Epidermoid and pilar cysts are commonly referred to as ‘sebaceous cysts’. These are smooth round lumps which you can see and feel just beneath the skin surface. They are very common.
- Epidermoid cysts can affect anyone but are most common in young and middle-aged adults. They can appear anywhere on the skin but develop most commonly on the face, neck, chest, upper back and sometimes on the scrotum.
- Pilar cysts can affect anyone but are most common in middle-aged women. They can appear anywhere on the skin but develop most commonly on the scalp. It is common for several to develop at the same time on the scalp.
