Cyst on the Skin Surface: What to Know

A superficial skin cyst may look like a round, skin-coloured or pale bump, sometimes with a visible central pore. It can feel firm, soft, or slightly mobile. Many are quiet, but friction, pressure, or bacterial inflammation can make one sore, red, warm, or swollen. A pimple, abscess, wart, molluscum, or other growth may resemble a cyst, so a surface appearance does not establish the diagnosis.

Do not lance, squeeze, or scrape the area. If it opens, cover it lightly with a clean dressing and wash your hands after touching it; avoid sharing towels until a clinician has assessed drainage.

Arrange a routine appointment for a persistent bump, repeated swelling, or a lesion that is rubbing against jewellery, footwear, or clothing. A clinician may recommend observation, an anti-inflammatory approach, drainage when an abscess is present, or removal of the cyst wall. Explore [Skin Lumps](/symptoms/skin-lumps/), [Abscess Drainage](/treatments/minor-procedures/abscess-drainage/), and [Cyst Removal](/treatments/surgical-dermatology/cyst-removal/).

Get prompt medical advice when pain, redness, heat, swelling, or drainage is increasing. Fever, spreading redness, red streaks, or marked tenderness can indicate infection. Have a clinician review any lump that enlarges quickly, becomes fixed, bleeds repeatedly, forms an ulcer, or does not heal. Seek urgent help if you feel severely unwell or swelling is rapidly progressing.

Ask what features support a cyst diagnosis, whether the lesion can be watched, and what to do if it opens. For a red or tender lump, ask whether [Steroid Injection Into The Skin](/treatments/injectables/intralesional-steroid-injection/) is appropriate or whether infection changes the plan. Ask how wound care and follow-up would work after removal.
