- Stye vs Chalazion vs Sebaceous Cyst: How to Tell the Three Eyelid Lumps Apart
Stye vs Chalazion vs Sebaceous Cyst: How to Tell the Three Eyelid Lumps Apart
A stye is a painful, red, infected lump at the lid edge that usually settles within about a week. A chalazion is a firm, usually painless blocked oil gland further back in the lid that can take weeks to months. A "sebaceous cyst" is usually neither: it is normally an epidermal cyst in the skin, which warm compresses will not clear. Any lump that keeps returning, grows or bleeds needs an eye specialist; our eyelid surgeon, Prof. Dr. Ahmet Satıcı, assesses these.
- If it is painful, red and near the lashes, it is most likely a stye. It is an infection, and warm compresses plus patience are the first step. Do not squeeze it.
- If it is firm, painless and further back in the lid, it is most likely a chalazion. It is a blocked gland, not an infection, and it can last longer. Antibiotics rarely help; a doctor can inject or drain one that will not go.
- If it is smooth, slow-growing, never hurts and never shrinks, think "cyst" or something else. The term "sebaceous cyst" is usually a misnomer, and a lump that does not behave like a stye or chalazion should be examined rather than treated at home.
Stye vs chalazion vs sebaceous cyst: side by side
"Hordeolum" is simply the medical word for a stye, so "stye vs hordeolum" is one lump under two names. The real comparison is between an infected gland (stye), a blocked gland (chalazion) and a lump in the skin (what people call a sebaceous cyst).
| Stye (hordeolum) | Chalazion | "Sebaceous cyst" (usually an epidermal cyst) | |
|---|---|---|---|
| What it is | Bacterial infection of an eyelash follicle or lid gland | Blocked meibomian (oil) gland with sterile inflammation (a chronic lipogranuloma) | A benign cyst from the upper part of a hair follicle, filled with keratin and fatty debris |
| Infection? | Yes | No | Only if it becomes infected or ruptures |
| Where on the lid | At or near the lid edge, at the base of a lash (an internal stye sits deeper) | Further back in the lid, away from the edge | In the skin, often a smooth dome, sometimes with a tiny central opening |
| Pain | Painful and tender | Usually painless or mildly tender | Painless unless infected |
| How it looks | Red, swollen, sometimes a yellow pus spot | Firm, round lump; the lid may be a little red | Firm, flesh-coloured or yellowish nodule |
| Usual course | Often settles in about a week | Often about a month; can be weeks to months | Does not usually settle on its own |
| Does a warm compress help? | Yes, first-line | Yes, first-line | It is not a treatment for a cyst |
| Antibiotics? | Rarely needed | Rarely help | Only if infected |
| If it does not go | Doctor may drain it with a sterile needle or remove the nearest lash | Steroid injection or minor drainage under local anaesthetic | Removal under local anaesthetic, taking the whole cyst lining |
| Who to see | GP, pharmacist or optometrist first | GP first; an eye specialist if it persists | GP or eye specialist |
Sources for the table: NHS, the American Academy of Ophthalmology (AAO), EyeWiki, MedlinePlus and DermNet NZ (full list below). An American Family Physician review gives the same rule of thumb: a well-defined mass at the lid margin is often a stye, and a mass in the middle of the lid is commonly a chalazion.
Which lump do you most likely have, and what should you do?
Your lump is probably a stye if…
- It appeared over a day or two and hurts. Pain and tenderness are the stye's signature. The NHS describes a small, painful lump that is often red, may show yellow pus and usually affects one eye. Your vision should not change.
- It is at the lid edge, by a lash. An external stye forms at the base of an eyelash.
- You have blepharitis or rosacea. The NHS says both make a stye more likely.
What suits you: home care. The NHS advises a clean, warm flannel on the closed eye for 5 to 10 minutes, 2 to 4 times a day, painkillers such as paracetamol or ibuprofen if needed, no contact lenses or eye make-up until it has healed, and no squeezing. See a GP if it has not improved after a few weeks.
Your lump is probably a chalazion if…
- It is firm and barely hurts. The AAO says a chalazion is "not usually painful" and develops farther back on the lid than a stye.
- It followed a stye. A Cochrane review notes that an acute internal hordeolum that does not settle can become a chalazion, and MedlinePlus describes a lid that is tender and swollen at first, then a firm lump that remains.
- It has been there for weeks. EyeWiki says an untreated chalazion may resolve over weeks to months; MedlinePlus says most resolve within about a month with conservative care.
What suits you: the same warm compresses, with gentle massage if you like (the AAO suggests 10 to 15 minutes, 3 to 5 times a day), then a specialist if it is large, affects your vision or has not gone after several weeks.
Your lump might be a cyst, or something else, if…
- It is smooth, slow-growing and painless, and does not come and go. A stye or chalazion usually changes within weeks; a true cyst does not.
- It has a tiny central opening, typical of an epidermal cyst according to DermNet NZ.
- It is a flat yellow patch near the inner corner of the upper lid. That is more likely xanthelasma, a fatty deposit in the skin, not a cyst at all.
What suits you: an examination. A doctor can confirm what it is and, if it bothers you, remove a true cyst under local anaesthetic.
Is a "sebaceous cyst" on the eyelid real?
Rarely, and the name itself is misleading. DermNet NZ explains that these cysts "do not involve sebaceous glands, nor do they contain sebum": the lump people call a sebaceous cyst is normally an epidermoid (epidermal) cyst, which arises from the upper part of a hair follicle. The correct label matters because the treatment is different from that of a stye or chalazion.
On the eyelid, a "sebaceous cyst" is usually one of these:
| Lump | What it is | How it differs from a stye or chalazion |
|---|---|---|
| Epidermal cyst | Keratin-filled cyst in the skin | Not an oil-gland problem; painless unless infected; does not come and go |
| Hidrocystoma | Cyst of a sweat gland | A sweat gland, not an oil gland; the commonest benign lid lesion in one Saudi hospital series |
| Intratarsal keratinous cyst | Keratin cyst inside the firm plate of the lid | Deep in the lid, so it can be mistaken for a chalazion |
| Xanthelasma | Fatty deposit in the skin | Not a cyst: yellow-orange patches, typically emerging between ages 35 and 55, affecting women about twice as often as men, and often associated with raised blood fats |
Studies of lumps removed from eyelids show how varied they are. In a hospital series of 35 surgically removed eyelid cysts, the commonest diagnosis was epidermal cyst (16), followed by intratarsal keratinous cyst (5), and none recurred after removal. In a Saudi teaching-hospital series of benign eyelid lesions, the commonest was the sweat-gland hidrocystoma, followed by chalazion, skin tag and epidermal cyst. The lesson is that you cannot reliably name an eyelid lump by looking at it, which is why a persistent one deserves an examination.
How long does each one last?
| Typical course | Source | |
|---|---|---|
| Stye | Common, and should go away within a week; see a GP if it has not improved within a few weeks | NHS |
| Chalazion | Most resolve within about a month with conservative care; untreated, it may clear over weeks to months | MedlinePlus; EyeWiki |
| Epidermal cyst | Complete surgical removal with the cyst lining is the most effective treatment; leaving the lining behind raises the chance of it returning | DermNet NZ |
Both a stye and a chalazion can come back after healing. If one keeps returning in the same place, see the red flags below.
Treatment compared: what works for each
Warm compresses are the first step for both a stye and a chalazion. Timings differ slightly between sources, so treat them as a range:
| Source | Compress advice |
|---|---|
| NHS (stye) | 5 to 10 minutes, 2 to 4 times a day |
| AAO (stye and chalazion) | 10 to 15 minutes, 3 to 5 times a day |
| MedlinePlus (chalazion) | 10 to 15 minutes, at least 4 times a day |
Whichever you use, do not squeeze or try to pop either lump: the AAO and the NHS both warn that it can spread infection.
Do antibiotics help? Usually not. A review of 2,712 patients treated at one US university found that adding an antibiotic to conservative care did not make a chalazion or a stye more likely to resolve, even though 36.5% received one.
If a chalazion will not go, there are two minor procedures; the AAO says drainage is done under local anaesthesia, and in the randomised trial below both were:
| Steroid injection | Incision and curettage (minor surgery) | |
|---|---|---|
| What happens | A small dose of steroid is injected into the lump | The lump is drained and its contents scraped out |
| Randomised trial (94 patients, after failed conservative care) | 81% resolved, on average in 5 days; 92% needed a single injection | 79% resolved |
| Meta-analysis of 8 trials | 60.4% success after one injection, 72.5% after one or two | 78.0% success after one procedure, 86.7% after one or two |
| Possible downsides (EyeWiki) | Skin lightening or darkening, thinning of the fat under the skin, skin breakdown; very rarely, visual loss | The lump can return; removed tissue is sent for pathology |
Success after one injection ranged from 8.7% to 86.7% across studies, so your doctor chooses by the size, position and age of the lump. EyeWiki calls incision and curettage the treatment of choice for large or unresolved symptomatic chalazia.
A true cyst is different. It is treated by complete removal, and taking out the whole cyst lining lowers the chance of it coming back (DermNet NZ).
When is an eyelid lump serious?
Most eyelid lumps are harmless, but a few need prompt care.
Same-day medical help (NHS 111 in the UK, or your local urgent-care service) if:
- the eyelid is very painful or swollen, there is pus, your vision is affected or the infection seems to be spreading (the NHS's urgent signs for a stye)
- you cannot move the eye normally or your vision changes: these can point to orbital cellulitis, a serious infection around the eye, which an American Family Physician review separates from the more common preseptal cellulitis by changes in eye movement and vision
See an eye specialist promptly if your "stye" or "chalazion":
- keeps coming back in the same place
- has lasted more than a few weeks and is not shrinking
- is growing, bleeding or changing colour
- is making lashes fall out (MedlinePlus lists lash loss and a lump that keeps enlarging as reasons to seek care)
- is large enough to blur your vision (EyeWiki notes that a large chalazion can press on the cornea and cause astigmatism)
Why the caution: a rare cancer called sebaceous gland carcinoma can masquerade as a stubborn chalazion. In a series of 60 patients reported in Ophthalmology in 2004, 20% had first been given a diagnosis of chalazion and 25% of blepharoconjunctivitis; the median age at referral was 72, and 73% were women. A 2025 BMJ Case Reports article described a sebaceous carcinoma that presented as a chalazion not responding to treatment and was diagnosed by biopsy. These cases are uncommon, which is exactly why EyeWiki advises that recurrent or atypical chalazia be sent for pathology.
At Laser Istanbul Clinic, a lump that does not behave like a stye or chalazion is assessed by our eyelid surgeon, Prof. Dr. Ahmet Satıcı, and, where a tumour is a concern, alongside Doç. Dr. Muhammet Derda Özer (Doç. means Associate Professor), who treats ocular tumours. Our third surgeon, Op. Dr. Aysan Bayram, works in cataract, laser and retinal care.
What does each cost to deal with?
Home care for a stye or a chalazion costs almost nothing: a clean flannel, warm water and time. Most people never need more than that, which is why we would never suggest travelling abroad for a stye. A first look from your GP, pharmacist or optometrist is usually enough.
Costs rise only when a lump needs a procedure or specialist assessment:
| Route | Typical cost position |
|---|---|
| Stye, home care | Negligible |
| Chalazion, home care | Negligible |
| Steroid injection or minor drainage of a persistent chalazion | A minor procedure; the price varies by country and clinic, so ask for a written quote |
| Removal of a true cyst under local anaesthetic | A minor procedure; the price varies by country and clinic |
| Eyelid surgery (blepharoplasty) for loose skin or fat, if you want it | Typical advertised packages in 2025–26: about $2,200–4,800 in Istanbul against $4,000–10,000 in the UK for upper and lower eyelids together, roughly 50–60% less (comparing the middle of each range) |
Advertised ranges, not quotes; the Istanbul figures are packages that often include a hotel and transfers, so compare like with like. At Laser Istanbul Clinic, eyelid surgery starts from {{price}}. Included: pre-operative examination and scans, surgery by your named surgeon, medication, follow-up checks in Istanbul, a personal interpreter, a coordinator and remote follow-up. Not included: flights, hotel and airport transfers, which are a separate charge arranged on request.
If a lump turns out to be a cyst and you also want your eyelids treated, planning both with one surgeon can save a trip. See what is included, and how each price is set, on the price list.
Where eyelid surgery comes in, and what to read next
A stye or chalazion is not treated with cosmetic eyelid surgery, and most people never need an operation for either. Surgery enters the picture when the lid itself needs attention: a persistent lump that a specialist wants removed and examined in a laboratory, or other changes you notice while checking a lump, such as hooded upper-lid skin, lower-lid bags or xanthelasma patches. If you are already considering eyelid surgery, have any lid lump examined first so it is not missed.
Frequently asked questions
A stye is a painful bacterial infection at the lid edge. A chalazion is a firm, usually painless blocked oil gland further back in the lid. A "sebaceous cyst" is usually an epidermal cyst in the skin, a slow-growing painless lump that does not come and go. Warm compresses help the first two but are not a treatment for the third.
No. A stye is an infection and is painful, usually at the lid edge. A chalazion is sterile inflammation from a blocked gland, usually painless and further back in the lid. A stye can sometimes turn into a chalazion if it does not drain fully.
None: hordeolum is the medical name for a stye. An external hordeolum is a classic stye at the lash base; an internal hordeolum is an infected meibomian gland deeper in the lid, and it is the kind that can become a chalazion.
No. DermNet NZ says "sebaceous cyst" is a misnomer for an epidermoid cyst, which comes from a hair follicle and contains keratin, not sebum. It is painless unless infected, and a doctor can remove it under local anaesthetic if it bothers you.
A stye should go away within about a week, according to the NHS; see a GP if it has not improved after a few weeks. A chalazion is slower: most resolve within about a month with conservative care, and an untreated one can take weeks to months.
Usually not. A review of 2,712 patients found no clear benefit from adding an antibiotic to conservative care for either. A doctor will prescribe one if the infection is spreading through the lid.
No. The NHS and the AAO both warn that squeezing can spread infection. Use warm compresses and let it drain by itself; if it does not, a doctor can drain it with a sterile needle or a minor procedure.
Most are harmless. See a specialist for a lump that keeps returning, grows, bleeds, makes lashes fall out or has not gone after several weeks, because a rare cancer called sebaceous gland carcinoma can look like a chalazion. Get same-day help for severe pain, pus, changes in vision or trouble moving the eye.
No, and we would not suggest it. A stye or chalazion can usually be managed by your own GP, pharmacist, optometrist or eye clinic. Travel makes sense only if you want eyelid surgery, or a specialist assessment of a lump that will not settle alongside other eyelid or eye care.
