Sebaceous Cyst Removal
Sebaceous cysts are benign, slow-growing lumps under the skin filled with keratin. Simple surgical excision removes them permanently with minimal scarring in a quick office procedure.
Overview
A sebaceous cyst (epidermoid cyst) is a closed sac under the skin filled with a cheese-like material called keratin. They form when the cells of the skin's surface (epidermis) move deeper and continue to produce keratin. Common sites include the face, neck, back, and scalp. They're harmless but can become infected, inflamed, or cosmetically bothersome.
Complete surgical excision removes the entire cyst wall — this is the key to preventing recurrence. Under local anaesthesia, a small incision is made, the cyst is shelled out intact, and fine sutures close the wound. The procedure takes 15-20 minutes. Scarring is minimal, especially on the face where cosmetic technique is prioritised.
Causes
- Blocked sebaceous gland or hair follicle
- Skin trauma — cysts can form at sites of previous injury
- Genetic conditions — Gardner syndrome, basal cell nevus syndrome (multiple cysts)
- Acne — inflamed follicles may develop into cysts
Symptoms
- A round, firm, movable lump under the skin
- A small central dark spot (punctum) — the blocked pore
- Usually painless unless infected
- Redness, swelling, tenderness, and foul-smelling discharge if infected
Diagnosis
- Physical examination — characteristic appearance and feel
- Ultrasound — if the diagnosis is uncertain
- Culture — if the cyst is actively infected
Treatment Options
Complete surgical excision
Removal of the entire cyst and its sac. Minimal scar, permanent cure.
Incision and drainage
For infected cysts — draining pus and prescribing antibiotics. Definitive excision once the infection resolves.
Punch excision
For small cysts on the face — a tiny circular punch tool removes the cyst with virtually no scar.
Frequently Asked Questions
Can I squeeze out a sebaceous cyst at home?
No. Squeezing ruptures the cyst wall internally, causing inflammation and making eventual surgical removal more difficult. It also dramatically increases the infection risk.
Will the cyst come back after removal?
If the entire cyst wall is removed — no. If any fragment of the wall remains, recurrence is possible, which is why complete excision is important.
