Pilar cyst treatment and skin cyst removal follow different clinical paths because the two cyst types differ in structure, wall thickness, and recurrence behavior.

Minor surgery becomes necessary when a cyst grows, causes pain, shows signs of infection, or keeps coming back after drainage.
If you have a lump under your skin and you are trying to figure out whether it needs surgery or can safely wait, this guide breaks down the differences, treatment options, and decision points clearly.
TL;DR: Key Takeaways
- Pilar cysts grow from hair follicles (mostly on the scalp). Skin cysts (sebaceous/epidermoid) grow from the skin surface and appear on the face, neck, and torso
- Both types are benign, but neither resolves on its own
- Drainage offers temporary relief. Surgical excision removes the full sac and lowers recurrence risk significantly
- Minor surgery is a short, in-office procedure under local anesthetic with minimal downtime
- At Pinkal Medical Aesthetics in London, Ontario, nurse practitioners perform cyst excision in a single clinic visit
What Is a Pilar Cyst? (And How Is It Different from a Skin Cyst?)

What Is a Pilar Cyst?
A pilar cyst (also called a trichilemmal cyst) is a firm, round lump that forms from the outer root sheath of a hair follicle.
Key facts:
- About 90% develop on the scalp
- Filled with dense keratin (the protein in hair and nails)
- Has a thick, smooth cyst wall
- Often runs in families
- More common in women aged 25 to 55
Pilar cysts grow slowly and are almost always benign. But they do not go away on their own.
What Is a Skin Cyst (Sebaceous / Epidermoid Cyst)?
A skin cyst forms when cells from the skin surface get trapped beneath the epidermis and create a sac filled with soft, cheese-like keratin material.
Key facts:
- Appears on the face, neck, ears, upper back, chest, or torso
- Has a thinner, more fragile cyst wall than a pilar cyst
- May have a visible central pore or punctum on the surface
- Can become tender or inflamed if irritated or infected
- Sometimes produces a foul smell if contents leak
The term "sebaceous cyst" is commonly used by patients, but most of these are technically epidermoid cysts.
Pilar Cyst vs Skin Cyst: Side-by-Side Comparison
Not sure whether your lump is a cyst, mole, or something else entirely? Our guide on skin tags vs moles vs warts can help you narrow it down before your consultation.
How to Tell If You Have a Pilar Cyst or a Skin Cyst
Where Each Type Usually Appears
Location is the strongest initial clue.
- Pilar cysts: Scalp (90% of cases). Occasionally on the neck or face
- Skin cysts: Face, earlobes, behind the ears, neck, chest, upper back, shoulders
If your lump is on the scalp and moves slightly when pressed, a pilar cyst is the most likely explanation.
What They Feel Like Under the Skin
- Pilar cysts feel firm, smooth, and round. They sit just under the scalp skin and slide slightly under your fingers
- Skin cysts can feel softer. Some have a small dark dot (punctum) at the center. They may feel more tender if close to the surface
Neither type should feel rock-hard, rapidly expanding, or fixed to deeper tissue. Those signs warrant a prompt clinical assessment.
Warning Signs That Mean Either Type Needs Attention Now
Book a consultation if you notice:
- Rapid growth over a few weeks
- Redness, warmth, or increasing tenderness
- Pus, drainage, or foul-smelling discharge
- Pain that disrupts sleep, work, or daily activities
- A lump that feels fixed to underlying tissue or looks irregular
If you have other skin growths alongside your cyst — such as lipomas, our post on lipoma removal in London, Ontario covers what to expect from that assessment.
Important: These signs do not necessarily mean something is wrong beyond a cyst. But they do mean a practitioner should assess it in person rather than you monitoring it alone.
Pilar Cyst Treatment vs Skin Cyst Removal: What Is Actually Different?

How Pilar Cysts Are Treated
Surgical excision is the standard pilar cyst treatment. Because the cyst wall is thick and smooth, the sac often comes out intact in one piece.
The process:
- Local anesthetic numbs the area
- A small incision opens the skin over the cyst
- The entire sac is removed, ideally in one piece
- The incision is closed with sutures
The thick wall of a pilar cyst makes complete removal more straightforward. This lowers the chance of recurrence compared to cysts with thinner walls.
How Skin Cysts (Sebaceous / Epidermoid) Are Treated
Skin cyst removal follows a similar excision process, but the thinner wall creates an added challenge.
- The fragile wall can tear during extraction
- If any wall fragments remain, the cyst can regrow
- Extra care is needed to dissect the sac cleanly from surrounding tissue
Why the Treatment Approach Differs
The core difference comes down to wall integrity.
- Pilar cysts: Thicker wall = easier to extract intact = lower recurrence
- Skin cysts: Thinner wall = higher risk of fragmentation = slightly higher recurrence if not excised carefully
Both require the same basic procedure (excision under local anesthetic). But the surgical precision needed and the risk profile differ slightly.
Can Either Type Be Treated Without Surgery?
No topical cream, home remedy, or oral medication dissolves a cyst. A cyst is a physical structure (a sac with contents), and it requires physical removal.
Options that do not work long-term:
- Warm compresses (may soothe inflammation temporarily but do not remove the cyst)
- Squeezing or popping at home (increases infection and scarring risk)
- Drainage alone (empties the cyst but leaves the wall behind)
- Antibiotics (treat infection around a cyst, but do not remove the cyst itself)
If a cyst is bothersome, growing, or recurrent, surgical excision is the only treatment that addresses the root cause.
When Does a Cyst Actually Need Minor Surgery?

Signs Your Pilar Cyst Needs Surgical Removal
- It keeps growing and is now visible through your hair
- It catches on your hairbrush, comb, or headwear
- It has become tender or painful
- You have had it drained before and it came back
- You have multiple pilar cysts clustering on your scalp
Signs Your Skin Cyst Needs Surgical Removal
- It has become red, swollen, or warm to the touch
- It is leaking fluid or producing an odor
- It sits in a visible area (face, neck, ears) and affects your confidence
- It has been drained previously and returned
- It is growing steadily and pressing against nearby tissue
When You Can Safely Wait and Monitor
Not every cyst needs immediate surgery. You may be able to monitor it if:
- The lump is small, stable, and has not changed in months
- It causes no pain, tenderness, or functional issues
- It is in a non-visible area and does not bother you cosmetically
- There are no signs of infection
Why Drainage Is Not a Long-Term Solution
Drainage removes cyst contents but not the cyst wall. The sac refills with keratin, and the lump returns.
If you have been through this cycle already, our post on it's just a cyst — until it hurts to sit, walk, or sleep explains exactly why drainage keeps failing and when excision becomes the only logical step.
Drainage vs. excision:
- Drainage: Quick, temporary relief. High recurrence rate. Does not address the root cause
- Excision: Slightly longer procedure. Removes the full sac. Significantly lower recurrence
If a cyst has been drained once and come back, excision is the logical next step.
What Minor Surgery for Cyst Removal Actually Involves

Step-by-Step: What Happens During Cyst Excision
- Assessment. Your nurse practitioner examines the cyst and confirms the diagnosis
- Numbing. Local anesthetic is injected around the cyst site
- Incision. A small, precise cut is made over the cyst
- Removal. The entire cyst sac is extracted, ideally in one piece
- Closure. The incision is closed with sutures
- Aftercare briefing. You receive wound care instructions and a follow-up date
How Long Does the Procedure Take?
Most cyst excisions take 20 to 45 minutes. Smaller cysts in accessible areas (like the top of the scalp) tend to be on the shorter end.
Is Cyst Removal Painful?
The local anesthetic eliminates pain during the procedure. You may feel mild pressure or tugging, but sharp pain is rare.
After the anesthetic wears off, mild soreness is normal. Over-the-counter pain relief handles it for most patients.
Recovery Timeline After Minor Cyst Surgery
- Day 1 to 3: Mild swelling and tenderness. Keep the area clean and dry
- Day 3 to 7: Swelling decreases. Avoid heavy exercise and submerging the wound
- Day 7 to 10: Suture removal at your follow-up appointment
- Week 2 to 4: Incision continues to heal and fade
Most patients return to desk work, driving, and light activity the same day or the next day.
Scarring, Recurrence, and Results: What to Realistically Expect
Does Cyst Removal Leave a Scar?
Every incision produces some degree of scarring. However, scars from cyst removal are typically small and fade over time.
For a detailed look at what healing looks like after minor surgery at Pinkal Medical Aesthetics, read will my minor surgery leave a scar.
What affects scar visibility:
- Scalp cysts: Hair covers the scar in most cases
- Facial or neck cysts: Careful incision placement can minimize visibility
- Your skin's natural healing tendency
- How well you follow aftercare instructions
Can a Pilar Cyst or Skin Cyst Come Back After Surgery?
Recurrence is uncommon after complete excision. The primary risk factor for recurrence is incomplete removal, where part of the cyst wall stays behind.
What Increases the Risk of Recurrence?
- Drainage instead of full excision
- Cyst wall that fragmented during surgery (more common with thin-walled skin cysts)
- Family history of cyst formation (new cysts may develop in different locations)
- Infection at the time of removal (can complicate full extraction)
Is Cyst Removal Covered by OHIP? Cost Breakdown for Ontario

When OHIP May Cover Cyst Removal
- The cyst is infected, causing significant symptoms, or your physician suspects another condition
- A family doctor provides a referral with supporting documentation
- The removal is considered medically necessary, not elective or cosmetic
When You Pay Out of Pocket
- The cyst is stable, asymptomatic, and removal is elective
- You choose a private clinic for faster access or scheduling convenience
- The procedure is considered cosmetic (no infection, no symptoms)
How Much Does Cyst Removal Cost at a Private Clinic in Ontario?
Private cyst excision fees in Ontario generally range from $300 to $800, depending on:
- Cyst size and location
- Number of cysts removed in one session
- Complexity of the removal (infected or deep cysts may require more time)
Some extended health insurance plans cover a portion. Check with your provider before booking.
Pro Tip: If cost is a concern, ask the clinic upfront about pricing during your consultation. At Pinkal Medical Aesthetics, pricing is discussed transparently before any procedure.

Frequently Asked Questions
1. What is the difference between pilar cyst treatment and skin cyst removal?
Pilar cysts grow from hair follicles (mostly on the scalp) and have thick walls that often come out intact. Skin cysts (sebaceous/epidermoid) grow from the skin surface with thinner walls that can fragment during removal. Both require surgical excision, but the technique and recurrence risk differ slightly.
2. Which type of cyst is more likely to need surgery?
Both types may eventually need surgery if they grow, cause symptoms, or recur after drainage. Pilar cysts on the scalp often become bothersome because they catch on brushes and headwear. Skin cysts on the face or neck may prompt removal for both functional and cosmetic reasons.
3. Can I leave a cyst untreated if it does not hurt?
In many cases, yes. A stable, painless cyst that is not growing can be monitored. However, cysts do not resolve on their own and may grow over time. A one-time clinical assessment confirms the diagnosis and helps you plan if removal becomes necessary later.
4. How do I know if my cyst is infected?
Signs of infection include increasing redness, warmth, tenderness, swelling, pus or drainage, and sometimes fever. If you notice these signs, seek a clinical assessment promptly rather than waiting or attempting to treat it at home.
5. Do I need a referral to get a cyst removed in London, Ontario?
No referral is required to book a consultation at Pinkal Medical Aesthetics. You can contact the clinic directly. If you have a referral from your family doctor, bring it along as it may help with insurance or OHIP coverage considerations.
