Epidermoid (sebaceous) cysts are lumps under the skin. Occasionally one can find a small punctum on the overlying skin. The cyst is lined by wall and it contains white cheesy material.
They range in size from a few millimetres to several centimetres and commonly occur on the face, back and chest. Antibiotics can cause stomach upset or allergic reactions.
Surgical drainage poses the risk of pain, infection, bleeding, orallergic reaction to anaesthesia. If an abscess develops, antibiotics are often given.
When cysts and abscesses are removed, both the sac and the material inside are taken. Sebaceous cysts can be monitored by watching the size and noting any redness or swelling that may indicate infection. Any new or worsening symptoms should be reported to the doctor.
