Spot on the vulva: should you be worried?
In the vast majority of cases, a spot on the vulva is harmless.
It is most often an ingrown hair, a minor hair follicle infection (folliculitis), or a cyst.
Certain STIs, such as herpes or genital warts, can also cause spots, and thrush sometimes causes small, itchy red spots.
Consult a doctor if the spot is very painful, if it forms blisters, small sores, or growths, or if it does not go away after 3 weeks.
You noticed a spot while washing and are feeling anxious. Here is how to tell what is harmless and what needs medical advice.
What causes a spot on the vulva?
Spot on the vulva after hair removal: ingrown hair or folliculitis?
This is the most common cause, especially after shaving, waxing, or friction.
A hair grows beneath the skin, or the hair follicle becomes infected: a small red bump forms, sometimes with a white head of pus, tender to the touch.
It usually clears up on its own within a few days.
What is a boil on the vulva?
A boil (furuncle) is a deeper folliculitis, most commonly caused by staphylococcus bacteria. It forms a large, red, hot, and painful lump that grows before bursting. Do not squeeze or pop it yourself.
If it is very large, extremely painful, or accompanied by a fever, see a doctor.
White spot on the vulva: is it a cyst?
A small, firm, white or yellowish lump under the skin of the labia majora that is painless.
It is caused by a build-up of sebum. It is harmless and can remain for months.
Why do I have a lump on the labia of my intimate area?
A lump on one side, near the opening of the vagina, is often a Bartholin's cyst.
It affects around 3% of women, especially in their 20s and 30s.
Its size ranges from a pea to a golf ball. If it becomes infected, it turns into an abscess: very painful, red, and sometimes accompanied by a fever.
An abscess must be seen promptly by a doctor. If you are over 40 or postmenopausal, seek advice even for a painless cyst.
Spot on the vulva and thrush: what is the connection?
A yeast infection (thrush) can cause small red spots around the irritated area, along with intense itching, burning, and thick white discharge.
In this case, it is the thrush that needs to be treated.
Small itchy spots on the vulva: an irritation?
A new soap, laundry detergent, sanitary product, or lubricant can cause small, itchy red spots.
They disappear once you stop using the offending product.
Can a spot on the vulva be an STI?
Yes, certain sexually transmitted infections cause lesions that resemble spots. They have fairly specific signs.
Spot on the vulva: is it herpes?
Herpes starts with itching and burning, then small blisters appear, burst into painful sores, and crust over.
In women, the first outbreak is often more severe, accompanied by a fever and fatigue. It appears one to three weeks after infection.
The virus stays in the body and can cause further outbreaks, which are generally less severe. Antiviral treatment shortens the outbreaks.
Cauliflower-like bump on the vulva: genital warts?
Genital warts are caused by human papillomavirus (HPV).
They are pink or grey growths, often shaped like a small cauliflower, or small, smooth, flesh-coloured bumps.
They are generally painless, may itch or bleed, and can appear months after exposure.
They are treated by a doctor (cream, cryotherapy, laser). The HPV vaccine protects against the types that cause them.
Small painless bump or sore: molluscum or syphilis?
Molluscum causes small, round, smooth bumps with a small dimple in the centre.
Syphilis can cause a small, painless sore, known as a chancre, which often goes unnoticed.
In both cases, a medical examination is necessary.
If you think you may have been at risk, get an STI check, even if the spot disappears.
How to identify a spot on the vulva based on its appearance?
This table helps you get your bearings. It is not a substitute for an examination: several causes can look similar.
What you observe | Possible cause |
|---|---|
Small red spot, sometimes with pus, after hair removal | Ingrown hair or folliculitis |
Large, red, hot, very painful lump | Boil (furuncle) |
Small, firm, painless white or yellow lump | Sebaceous cyst |
Lump on one side, near the opening of the vagina | Bartholin's cyst (abscess if painful and red) |
Small red spots with itching and thick discharge | Thrush (yeast infection) |
Small blisters that burst into painful sores | Genital herpes |
Pink or grey, cauliflower-like, painless growths | Genital warts (HPV) |
Small, round, smooth bumps with a dimple in the centre | Molluscum contagiosum |
Small painless sore | Possible syphilis: see a doctor |
White or red patch, itching for weeks | Lichen sclerosus or other skin condition: see a doctor |
How to treat a spot on your intimate area?
For a harmless spot, such as an ingrown hair or folliculitis, a few simple steps are usually sufficient:
Do not squeeze, pop, or scratch it, to prevent infection.
Wash the area with warm water or a gentle, fragrance-free wash, then pat dry.
Apply a warm compress for a few minutes, several times a day. For a mildly painful Bartholin's cyst, warm sitz baths for 10 to 15 minutes, twice a day, are recommended.
Take a break from shaving or hair removal, and wear loose-fitting cotton underwear.
Do not apply steroid creams or acne products without medical advice.
When to worry about a spot on the vulva?
Most spots clear up within a few days.
Consult your GP or gynaecologist if you notice small blisters, sores, or growths, or if you think you may have been exposed to an STI.
You should also see a doctor if a spot is very large or very painful, if you develop a fever, or if a lump is growing near the opening of the vagina.
Any lesion that does not disappear after 3 weeks must always be checked, especially if it itches, bleeds, hardens, or forms an open sore.
This is also the case for a white or red patch that does not heal, or itching that has lasted for weeks.
Can a spot on the vulva be cancer?
This is very rare. Vulval cancer accounts for less than 5% of gynaecological cancers, with around 800 new cases per year in France, most commonly occurring after menopause.
It does not usually look like a spot that appears and then goes away, but rather like a persistent lesion. Hence the 3-week rule: if in doubt, get it checked—it will give you peace of mind.
Frequently asked questions
Itchy spot on the vulva and unusual discharge: what should you do?
When itchy little bumps are accompanied by thick white discharge or an unusual odour, a vaginal infection is likely. The Santelle vaginal test helps you find out from home whether your symptoms are more like thrush or bacterial vaginosis: 6 biomarkers, results in 10 minutes in the app. It does not detect herpes or genital warts: if you have blisters, sores or growths, consult a doctor.
Spot on the vulva during pregnancy: is it serious?
Most often not: these are generally the same benign causes as outside of pregnancy. However, do report the spot to your midwife or doctor, especially if it looks like blisters: herpes in late pregnancy requires specific monitoring (Santé.fr).
Can you pop a spot on your vulva?
It is best avoided: you risk worsening the infection and leaving a scar. Allow it to come to a head with warm compresses, or have it examined if it is large or painful.
Is a bump inside the vagina normal?
You can sometimes feel small bumps inside the vagina, which are often normal folds of the mucous membrane or small cysts. A new bump that grows or is painful should be checked.
How to avoid spots on the vulva?
Use a new razor blade and shave in the direction of hair growth, or increase the time between hair removal sessions. Wear cotton underwear, change clothes after exercising, and avoid perfumed products. Condoms and the HPV vaccine reduce the risk of STIs.
