Cyst Removal

Skin and scalp cyst evaluation with observation, inflammation treatment, drainage and surgical removal options when appropriate.

← Back to Surgical and Procedural Dermatology

Cysts can stay quiet for years or become painful, inflamed, drain, or simply get in the way.

We first make sure the lump really is a cyst and discuss whether observation, calming inflammation, drainage, or surgical removal makes the most sense.

When removal is chosen, we explain the scar, stitches, recurrence risk, and aftercare up front.

Common types of skin cysts

Epidermal inclusion cysts (epidermoid or “sebaceous” cysts)

An epidermal inclusion cyst is a sac beneath the skin filled with keratin, a protein found in the skin’s outer layer. It often develops on the face, neck, chest, or back. A small central opening, called a punctum, may resemble a blackhead. The cyst may release thick, sometimes foul-smelling material.

Many people call these “sebaceous cysts.” That familiar term is technically inaccurate: epidermoid cysts contain keratin rather than sebum, the oil produced by sebaceous glands. A ruptured cyst can become swollen and painful even without a bacterial infection.

Scalp cysts (pilar or trichilemmal cysts)

Pilar cysts develop from the outer root sheath of a hair follicle and occur most often on the scalp. They usually feel like firm, smooth, movable lumps and typically lack the central opening seen in epidermoid cysts. Some people have several, and they can run in families. A cyst may become uncomfortable when brushing hair or resting the head against a pillow.

Other cysts and look-alike bumps

Milia are tiny superficial keratin cysts, often seen on the face. Less common cysts, including dermoid cysts and steatocystomas, have different origins and may require a different approach. A lipoma, abscess, acne nodule, or other growth can also look like a cyst. An examination helps establish the diagnosis; learn more about other scalp growths.

How are cysts diagnosed?

Diagnosis often begins with examining and feeling the lump. Your clinician will ask about growth, tenderness, drainage, and prior treatment. When the diagnosis is uncertain or the lump has unusual features, tissue examination or additional evaluation may be recommended.

Cyst treatment and removal

Observation: A confirmed benign cyst that causes no symptoms may not need treatment.
Reducing inflammation: An injection of a corticosteroid, such as triamcinolone, may help selected inflamed cysts settle. It does not remove the cyst wall.
Antibiotics when indicated: Antibiotics may be prescribed for a bacterial infection. Redness and swelling alone do not mean a cyst needs antibiotics.
Incision and drainage: Opening and draining a painful cyst can relieve pressure. Because the lining may remain, the cyst can refill. Read about incision and drainage.
Surgical excision: Removing the cyst and its lining under local anesthetic offers the best chance of preventing recurrence at that site. Removal may be scheduled after acute inflammation settles.

What should I expect after removal?

You will receive wound-care instructions and guidance about activity and follow-up. Stitches may be needed. Removal leaves a scar, and potential complications include bleeding, infection, pigment changes, and recurrence. Removing one cyst does not prevent a new cyst from developing elsewhere.

When should a lump be checked?

Arrange an evaluation for a new or changing lump, repeated drainage, or a cyst that interferes with daily activities. Rapid growth, bleeding, or a firm, fixed lump deserves assessment rather than assuming it is a harmless cyst. Seek prompt care for fever, spreading redness, or worsening pain. Do not squeeze, puncture, or attempt to cut out a cyst at home.

Schedule a cyst evaluation
