Cysts on the clitoral hood are almost always benign growths caused by trapped skin cells or blocked follicles beneath the surface of the skin. The most common type is an epidermal inclusion cyst, a slow-growing, painless lump filled with a protein called keratin, the same material that makes up your outer skin layer and nails. While they can be alarming to discover, these cysts rarely pose a serious health risk.
How These Cysts Form
The clitoral hood, like the rest of the vulva, is covered in skin that naturally sheds old cells. Normally those cells slough off and wash away. But when skin cells get trapped beneath the surface, they can accumulate inside a small pocket lined with the same tissue as your outer skin. Over weeks or months, layers of keratin build up inside that pocket, forming a firm, round lump. This is the basic mechanism behind an epidermal inclusion cyst.
These cysts are sometimes called “sebaceous cysts,” but that name is misleading. They don’t actually involve the oil-producing (sebaceous) glands. Instead, they develop from the upper part of a hair follicle when its opening becomes plugged. The clitoral hood has fine follicles and glands that make it susceptible to this kind of blockage, though cysts here are still considered rare compared to locations like the scalp, neck, or trunk.
Trauma and Scarring
Physical trauma to the vulvar area is another well-documented cause. When skin is cut, torn, or scarred, fragments of the outer skin layer can get pushed beneath the surface and become trapped in the healing tissue. The buried skin cells continue doing what they normally do: producing keratin. With nowhere for that material to go, a cyst gradually forms within the scar.
This mechanism explains why epidermal inclusion cysts have been reported after episiotomy, genital injury, and female genital mutilation (FGM). In a systematic review covering cases published between 2000 and 2024, researchers identified 162 patients with cysts in the clitoral region. Of those, 132 cases were linked to FGM, 27 were spontaneous (no identifiable trauma), and 2 were associated with other genital trauma. Piercings in the clitoral hood area can also introduce this risk, since the piercing creates a wound channel where skin cells may become entrapped during healing.
Hormonal Influences
Hormonal fluctuations can play a role in vulvar cyst development, particularly for cysts related to the oil glands in genital skin. The vulva has a high concentration of sebaceous glands that respond to androgens, hormones present in all women at varying levels. When androgen activity increases, these glands can become overactive, producing excess oil that contributes to blocked pores and cyst formation.
Some women notice vulvar cysts worsening during the second half of their menstrual cycle (the luteal phase), when certain hormone levels shift. In documented cases, anti-androgen treatments have successfully prevented new cysts from forming, which supports the hormonal connection. This pattern tends to affect premenopausal women and can be a recurring issue over years.
Adhesions and Pseudocysts
Not every lump on the clitoral hood is a true cyst. In some cases, the skin of the hood can fuse to the underlying tissue, trapping shed skin cells and natural secretions (sometimes called smegma) in the space beneath. This creates what’s known as a pseudocyst, a cyst-like swelling that forms not from a distinct cyst wall but from adhesion of the surrounding skin. Clitoral adhesions can develop from chronic irritation, low estrogen levels (particularly after menopause), or conditions that cause skin thinning and scarring in the vulvar area.
What a Clitoral Hood Cyst Feels Like
Most clitoral hood cysts are painless and grow slowly. You might notice a small, firm, round bump that feels mobile under the skin when you press on it. The overlying skin typically looks normal, without redness or discoloration, and the lump is usually smooth and well-defined. Some cysts remain tiny for years, while others gradually enlarge. Cases have been documented where cysts grew to 6 centimeters before the person sought treatment, though most are much smaller.
Only 2 out of 162 patients in one literature review were completely asymptomatic. Most people notice the cyst because of its size or mild tenderness, discomfort during physical activity, or concern about its appearance.
Signs of Infection
A cyst can become infected if bacteria enter through a small break in the skin or through the cyst’s opening. When this happens, symptoms escalate quickly, sometimes within days. An infected cyst typically becomes:
- Painful and tender to the touch, sometimes throbbing
- Red and warm over the surface
- Swollen beyond its usual size
- Associated with fever in more severe cases
An infected cyst may also cause discomfort while walking, sitting, or during intercourse. If a cyst becomes painful and doesn’t improve after two or three days of warm compresses, it likely needs professional evaluation.
How It Differs From a Bartholin’s Cyst
One of the most common mix-ups is confusing a clitoral hood cyst with a Bartholin’s cyst. These are different conditions in different locations. Bartholin’s glands sit at the lower part of the vaginal opening, at roughly the 4 o’clock and 8 o’clock positions. A Bartholin’s cyst forms when one of these gland ducts gets blocked and fluid backs up. It shows up as a soft, sometimes fluctuant swelling near the vaginal entrance.
A clitoral hood cyst, by contrast, sits at the top of the vulva, over or near the clitoris. It tends to feel firmer, appears as a yellowish-white or skin-colored nodule, and is filled with solid keratin material rather than fluid. The distinction matters because the causes, anatomy, and treatment approaches differ. A healthcare provider can usually tell them apart with a physical exam alone.
Treatment and Removal
Small, painless cysts that aren’t growing often don’t need any treatment. Applying a clean, warm, damp cloth to the area for 15 to 20 minutes daily can sometimes help a cyst drain on its own or reduce tenderness.
When a cyst is large, painful, recurrent, or interfering with daily life, surgical excision is the standard approach. Because the clitoral area is rich in sensory nerves, surgeons sometimes map the nerve distribution before operating. In one described technique, a lubricated cotton swab is used to stroke different areas of the clitoral hood while the patient identifies which zones feel sensual versus neutral. The incision is then placed in the non-sensual zone to preserve sensation. The cyst is carefully separated from the surrounding nerve tissue, removed intact with its capsule, and the incision is closed in layers. Removing the entire cyst wall is important because leaving fragments behind increases the chance of recurrence.
Recovery is generally straightforward, and preserving the nerve bundle means sensation in the area remains intact. For hormone-related recurrent cysts, treatments that reduce androgen activity have shown good results in preventing new cysts from developing.
