Sebaceous cyst removal in Edinburgh
A sebaceous cyst is a firm, harmless lump that is removed when it becomes tender, infected or bothersome. The aim is to take out the whole sac, because draining a cyst alone leaves the wall behind and it usually comes back.

What sebaceous cysts are
Most “sebaceous” cysts are technically epidermoid or pilar cysts — sacs of keratin that form when a hair follicle becomes blocked. They are common, benign and not infectious, appearing most often on the scalp, face, neck, back and chest. They grow slowly and may be present for years before becoming bothersome — typically when they enlarge, become tender or infected, or discharge. Multiple cysts are common, particularly with a family history.
Why complete excision matters (not just drainage)
A sebaceous cyst can often be drained — a small incision is made, the keratin contents are squeezed out, and the cyst flattens. This provides temporary relief, but the cyst wall remains. Because the wall is the structure that produces the keratin, the cyst usually reforms over the following weeks to months. Drainage alone is therefore not a definitive treatment.
Complete excision removes the entire cyst sac along with its contents. When the cyst is not actively inflamed, this is straightforward: a small ellipse of skin is removed over the cyst, the sac is dissected out intact, and the wound is closed with sutures. Performed properly, recurrence is uncommon.
The wrong moment for complete excision is when a cyst is acutely inflamed or infected. In that situation, the cyst wall is fragile and difficult to remove cleanly, and excision often leaves cyst-wall fragments behind. The standard pathway is to treat the inflammation first — antibiotics when needed and incision and drainage if the cyst is fluctuant and painful — and then return for complete excision once the area has settled, usually 6 to 8 weeks later.
When to seek removal
Patients commonly book cyst removal when:
- A cyst has become tender, swollen, or has discharged keratin (this is sometimes the patient’s first awareness of the cyst)
- A cyst has been infected once or more — recurrent infection is a strong indication for definitive excision
- A cyst is enlarging and starting to become bothersome
- A cyst is in a visible site such as the face, neck, or scalp and is cosmetically obvious
- Multiple cysts are present and the patient would like a definitive plan
If your cyst is currently inflamed, contact us — the appointment plan will usually include settling the inflammation first and booking definitive excision a few weeks later.
How removal is performed
The standard procedure for a non-inflamed cyst is complete excision under local anaesthetic.
Local anaesthetic is infiltrated around the cyst.
A small ellipse of skin is removed over the cyst, oriented along the natural skin tension lines to minimise scarring. The size of the ellipse depends on the cyst.
The cyst sac is dissected out intact, preserving the wall so the entire structure is removed in one piece.
The wound is closed with sutures, often in two layers (deep and skin) to support healing and reduce scar tension.
The specimen is sent for histology in every case to confirm the diagnosis and exclude unusual pathology.
Larger cysts (over 5cm), or cysts in anatomically challenging sites (close to important nerves, vessels, or facial features), may be planned under sedation or general anaesthesia and may require local flap reconstruction. This is discussed in detail at the consultation.
What cyst removal can and can’t do
Taking out the whole cyst sac is the only treatment that stops a cyst coming back. It swaps a lump for a scar, and it cannot stop new cysts forming elsewhere.
It can
- Remove the cyst and its sac in one visit under local anaesthetic, once any inflammation has settled.
- Give the lowest chance of the same cyst returning, because the sac that makes the contents is gone.
- Confirm the diagnosis, because every cyst we remove goes for histology.
- Place the scar along the natural skin lines wherever the site allows.
It can’t
- Be done without a scar. The scar is usually a little shorter than the cyst was wide; on the scalp it hides in hair, on the face or neck it will show.
- Be done well while the cyst is inflamed. An inflamed sac tears and leaves fragments behind. We settle the inflammation first and remove the cyst a few weeks later.
- Promise it will never come back. Recurrence is uncommon after a complete excision, but a fragment of sac can be left, especially on the back or ear or after previous infection.
- Stop new cysts. People prone to cysts, particularly on the scalp, go on forming them.
- Replace drainage when a cyst is acutely infected. A hot, painful cyst needs antibiotics or incision and drainage first, which relieves it but does not remove the sac.
Your consultant will tell you at your consultation which of these apply to you.
What sebaceous cyst removal costs
Pricing depends on the cyst’s size and the complexity of the closure.
- Cases requiring sedation or general anaesthesia — priced after assessment
Final pricing is confirmed in writing after consultation, based on the size, site, and method required.

Your consultants
Sebaceous cyst removal at Waterfront is performed by Mr Ben Aldridge — the UK’s only consultant dual-qualified in dermatology and plastic surgery — and by Mr Kazem Nassar, consultant plastic and reconstructive surgeon. Both are on the GMC Specialist Register. The consultant who assesses you is the consultant who performs the removal and reviews you afterwards.
You meet your consultant at your first appointment. The same consultant plans your treatment, carries it out and sees you afterwards.

Risks, and how often they happen
Every procedure carries risk. Here they are in three groups, with how often they happen where the evidence allows. Your consultant will go through them with you, and they are in your written consent.
Expected Almost everyone, and they settle
- A scar, a little shorter than the cyst was wide, placed along the skin lines where possible. It is red or pink at first and fades over 12 to 18 months.
- Swelling and bruising around the wound for the first one to two weeks.
- Discomfort for a day or two, eased by simple painkillers.
- Numbness or altered sensation around the scar, which usually settles over weeks to months and occasionally persists.
Uncommon Some patients, and some need further treatment
- The cyst coming back, because a fragment of the sac was left behind. It can be removed again.Uncommonno reliable figure for standard excision
- Wound infection that needs a course of antibiotics.Under 1 in 50higher on the scalp, in the groin and after previous infection
- Bleeding after surgery that needs pressure, a dressing change or a return to have the wound checked.Under 1 in 100usually settles with pressure
- A fluid collection in the cavity after a large cyst, which may need draining with a needle.Uncommonlarger cysts; no reliable figure
- A raised, thickened scar (hypertrophic or keloid), more likely on the chest, shoulders, upper back and earlobes and in darker skin. It can be treated but not always fully flattened.Uncommonno reliable figure
Rare but serious
- Injury to a nerve beneath the skin on the face, neck or scalp, which can cause lasting numbness or, rarely, weakness of a nearby muscle. Your consultant plans around the known danger zones.Rareno reliable figure
- An unexpected histology result, which your consultant discusses with you in person.Rare
- A serious reaction to the local anaesthetic.Very rare
- A serious reaction to a general anaesthetic, where one is used for a large or awkwardly placed cyst.Very raregeneral anaesthetic cases only
For the long term
- New cysts are common, especially on the scalp and in people with several already. Each is a separate decision.
- Scars keep changing for a year or more. Protect a new scar from the sun for the first year, and tell us if it thickens, because early treatment of a raised scar works best.
- Do not squeeze a cyst. Bursting it under the skin sets up inflammation and makes a later removal harder.

Aftercare
Wound care advice is provided in writing on the day of the procedure. Stitches are removed at 7 to 14 days, depending on the site. The Waterfront nursing team is available for the first week for any wound-related concerns. Your consultant remains accessible after the procedure — if anything concerns you, they will respond directly and arrange to see you as soon as needed.
Histology results are normally available within approximately two weeks and are communicated by the consultant who performed the procedure.
- Day of surgeryHome within the hour. Most skin surgery is under local anaesthetic.

- Days 7–14Stitches out at Waterfront.
