Sebaceous Cyst Removal in Edinburgh
Sebaceous cysts (more accurately epidermoid or pilar cysts) are firm, round lumps that develop in or just under the skin. They are common, harmless in themselves, and most people only seek treatment when a cyst becomes tender, infected, larger, or cosmetically bothersome.
At Waterfront Private Hospital, sebaceous cysts are removed by consultant plastic surgeons on the GMC Specialist Register. The goal is complete excision of the cyst sac — not just drainage of the contents. Drainage alone leaves the cyst wall behind, and the cyst routinely re-forms. Complete excision, when the cyst is not actively inflamed, gives the lowest recurrence rate and the best cosmetic result.
The consultant who assesses you at the consultation is the consultant who performs the removal and reviews you afterwards. Guide prices: from £695 for cysts under 2cm; from £895 for medium cysts; £1,195 to £2,500 for large cysts over 5cm.

What sebaceous cysts are
The term “sebaceous cyst” is widely used, but most are technically epidermoid cysts or pilar cysts — sacs of keratin within the skin, formed when a hair follicle or pilosebaceous opening becomes blocked. They are common, benign, and not infectious.
Cysts can develop anywhere on the body, but are most often found on:
- The scalp (where they are usually pilar cysts)
- The face, neck, and behind the ears
- The back and chest
- The groin
They tend to grow slowly and may be present for years before becoming bothersome. Most patients seek treatment because a cyst has started to enlarge, has become tender or infected, has discharged foul-smelling contents, or is cosmetically obvious. Multiple cysts are common in some patients, particularly those with a personal or family history of cyst formation.
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.
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.
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.
Risks and considerations
Sebaceous cyst removal is a small to moderate procedure with a low complication rate. The risks discussed at consultation include:
- Scarring — every excision leaves a scar. The scar length depends on the size of the cyst; placement and closure are planned to minimise the cosmetic impact.
- Bleeding and bruising — usually minor and self-limiting.
- Infection — uncommon; managed with antibiotics where needed.
- Recurrence — uncommon after complete excision of the cyst sac. More likely if any cyst wall is left behind, particularly if the cyst was inflamed at the time of surgery.
- Altered sensation — temporary numbness around the wound is common and usually resolves over several weeks to months.
- Pigmentation change — the area treated may heal lighter or darker than the surrounding skin.
- New cysts — removing one cyst does not prevent new cysts forming elsewhere. Patients prone to multiple cysts are followed with this in mind.
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.
What sebaceous cyst removal costs

Frequently asked questions about sebaceous cyst removal
Who performs sebaceous cyst removal at Waterfront?
Mr Ben Aldridge or Mr Kazem Nassar, both on the GMC Specialist Register. The consultant who assesses you at the consultation is the consultant who performs the removal.
Do I need a GP referral?
No. You can book a consultation at Waterfront directly. If you would like a copy of the consultation summary sent to your GP, the consultant can arrange that at the appointment.
How quickly can I be seen?
Consultation appointments are normally available within 1 to 2 weeks of enquiry. Removal is usually scheduled within two weeks of consultation.
What is the difference between draining a cyst and excising it?
Drainage releases the contents of a cyst through a small incision but leaves the cyst wall behind. Because the wall produces the keratin contents, the cyst usually re-forms. Complete excision removes the entire cyst sac and gives the lowest recurrence rate. Complete excision is the standard treatment at Waterfront, performed when the cyst is not actively inflamed.
What if my cyst is currently inflamed or infected?
An acutely inflamed or infected cyst is treated first — antibiotics where indicated, and incision and drainage if the cyst is fluctuant and painful. Complete excision is then planned a few weeks later once the area has settled. This two-stage approach is safer than attempting excision while the cyst wall is fragile.
What anaesthetic is used?
Local anaesthetic for most cases. Larger cysts or those in anatomically challenging sites may be planned under sedation or general anaesthesia. The choice is made at consultation.
Is the cyst sent for histology?
Yes, every excised cyst is sent for pathology to confirm the diagnosis and exclude unusual pathology.
Will the procedure leave a scar?
Every excision leaves a scar. The scar length depends on the size of the cyst, and placement is planned to follow the natural skin tension lines wherever possible. Your consultant will discuss the expected scar in detail at consultation.
Can a cyst come back after complete excision?
Recurrence is uncommon when the entire cyst sac has been removed intact. The risk rises if any part of the cyst wall is left behind, which is most likely when excision is attempted during active inflammation.
Can multiple cysts be removed in one session?
Yes, where they are close together and of a manageable total size. Pricing for multiple cysts is set at consultation. Cysts in different parts of the body are usually treated in separate sessions.
Are sebaceous cysts ever a sign of something more serious?
Almost always no — sebaceous, epidermoid, and pilar cysts are benign. Very occasionally, multiple cysts can be associated with inherited conditions such as Gardner syndrome. Where the pattern of cysts suggests this, your consultant will discuss further investigation at the consultation.
How is treatment paid for?
Waterfront Private Hospital is self-pay. The price you are quoted in writing after consultation covers the consultant’s fee, the hospital and theatre fees, histology, and routine post-operative reviews.
