A bump on or near the clitoris is almost always caused by something common and harmless, like a blocked oil gland, an irritated hair follicle, or a buildup of skin cells under the clitoral hood. Less often, it can signal an infection or a skin condition that benefits from treatment. Understanding what different bumps look and feel like can help you figure out what you’re dealing with.
Blocked Oil Glands and Cysts
The most common cause of a bump in this area is a sebaceous cyst. The skin around the clitoris and clitoral hood contains oil-producing glands, and when one gets blocked, a small lump filled with yellowish-white material forms beneath the skin. These cysts look and feel similar to a large pimple. They can be as small as a pea, though in rare cases they grow much larger.
Most sebaceous cysts are painless and don’t need treatment. They become a problem only if they get infected, at which point they may turn red, swell, feel tender to the touch, or even cause a fever. A warm compress can help a small, mildly irritated cyst drain on its own. If the swelling gets worse or doesn’t resolve within a week or two, a healthcare provider can drain it safely.
Irritated Hair Follicles
The tissue around the clitoris, especially the clitoral hood and surrounding labia, has fine hair follicles. When one of those follicles gets inflamed or infected, folliculitis develops. This is especially common after shaving or waxing, since small nicks in the skin let bacteria in. The result is a red, tender bump that looks like a pimple and typically resolves on its own within a few days. Keeping the area clean and avoiding further shaving while it heals usually does the trick.
Keratin Pearls and Smegma Buildup
Sometimes the bump isn’t a true growth at all. Under the clitoral hood, dead skin cells and natural oils can accumulate. This material, called smegma, normally washes away with regular cleaning. But if the clitoral hood is tight or partially adhered (a condition called clitoral phimosis), that buildup can get trapped and form a small, firm mass known as a keratin pearl. These are typically just a few millimeters in size and may appear as a tiny, shiny bulge under or beside the clitoris.
Keratin pearls form when the clitoral hood can’t fully retract, so the skin cells and debris have nowhere to go. They can cause localized irritation or tenderness. To prevent buildup, gently pull the labia apart during bathing and wash the area with warm water and a mild, fragrance-free soap. Avoid getting soap inside the vagina. Pat the area dry afterward and wear breathable underwear. If a keratin pearl has already formed and is causing discomfort, a provider can sometimes release it with a simple in-office procedure or topical treatment.
Herpes Blisters
Genital herpes (caused by HSV) produces a cluster of small blisters or open sores that are distinctly painful. Before lesions appear, many people notice tingling or burning in the spot where the outbreak is about to develop. The blisters eventually burst, leaving red, raw sores that heal over one to three weeks. If your bump is painful, appeared suddenly, and looks more like a blister than a firm lump, herpes is worth considering, particularly if you’ve had a new sexual partner. A provider can confirm the diagnosis with a swab test.
Genital Warts
Genital warts from HPV look quite different from herpes. They tend to be flesh-colored, raised or flat, and often have a rough, cauliflower-like texture. They’re usually painless. Some are so small they’re hard to see at all. Warts can appear on the clitoral hood, labia, or surrounding skin. They don’t go away on their own the way a pimple does, so if you notice a persistent, textured bump that isn’t tender, it’s worth having a provider take a look.
Syphilis Chancre
A primary syphilis sore, called a chancre, is a single, firm, painless bump that appears about three weeks after exposure to the bacteria. The key feature that distinguishes it from other bumps is that it’s round, well-defined, and notably not painful. It heals on its own within three to six weeks, which can trick people into thinking the problem resolved. It didn’t. Without treatment, syphilis progresses to more serious stages. If you have a painless sore that appeared after sexual contact, get tested promptly.
Lichen Sclerosus
Lichen sclerosus is a chronic skin condition that commonly affects the vulva, including the clitoral hood. Rather than a single round bump, it produces porcelain-white patches or raised plaques on the skin. The affected tissue may look pale, thin, or shiny, and you might notice itching, cracking, or small areas of bruising. Over time, lichen sclerosus can cause the clitoral hood to scar and fuse with surrounding tissue, sometimes trapping secretions underneath and forming a pseudocyst, a small fluid-filled bump under the scarred skin.
This condition doesn’t go away on its own and tends to worsen without treatment. If you’re noticing white patches, persistent itching, or changes in the shape of the skin around your clitoris, bring it up with a healthcare provider. Treatment typically involves a prescription topical medication that keeps symptoms under control and prevents scarring from progressing.
Piercing-Related Bumps
If you have a clitoral hood piercing, a bump near the site may be a keloid (raised scar tissue) or a granuloma (a small inflammatory nodule). These form from chronic irritation, friction from jewelry, or the body’s healing response to the piercing. Keloids are firm, smooth, and may grow slightly beyond the original piercing site. Granulomas tend to be smaller and redder. Switching to a different jewelry material, keeping the area clean, and reducing friction often help. Persistent or growing bumps near a piercing warrant a visit to either your piercer or a dermatologist.
When a Bump Needs Medical Attention
The vast majority of clitoral bumps are benign. Vulvar cancer is rare, affecting about 2.6 out of every 100,000 women per year, and it accounts for just 0.3% of all new cancer cases. It most often involves the outer labia rather than the clitoris. Still, certain features should prompt you to see a provider sooner rather than later:
- Rapid changes in a bump’s color, size, or border
- Bleeding from the bump or surrounding skin
- Persistence beyond two to three weeks without improvement
- Unusual blood vessel patterns or an irregular surface
- A bump that doesn’t respond to home care or prescribed treatment
In these cases, a provider may recommend a biopsy, a quick procedure where a small tissue sample is taken and examined. This is especially important for postmenopausal women with new bumps or anyone with a weakened immune system, since both groups have a slightly higher risk of atypical findings. For everyone else, a straightforward clinical exam is usually enough to identify the cause and decide on next steps.
