What should you know about keratin cyst removal?

Keratin cyst removal usually involves confirming the lump, numbing the skin, and removing the cyst wall to reduce regrowth. A clinician may recommend observation when the cyst is quiet, or a procedure when it is painful, repeatedly inflamed, catching on clothing, or troubling you cosmetically.

A keratin cyst is a sac beneath the skin containing keratin, a protein found in the outer skin layer. The material may be thick and have an unpleasant odour if the cyst opens. During planned removal, local anaesthetic numbs the area. The clinician makes a small opening, releases the contents, and aims to remove the surrounding lining. Draining alone can leave that lining behind, so the lump may return. If the area is actively inflamed, definitive removal may be delayed until the swelling settles.

Do not squeeze, pierce, or cut the lump at home; this can push material deeper and introduce infection. Keep the skin clean, avoid friction, and arrange an assessment if the diagnosis is uncertain or the cyst keeps returning. After a procedure, follow the dressing and wound-care instructions, keep the site protected, and avoid picking at a scab. Ask whether the removed tissue needs laboratory examination, particularly if the lump has an unusual appearance.

Seek prompt medical care if the lump becomes rapidly more painful, hot, red, or swollen, or if pus, spreading redness, fever, or feeling unwell develops. Arrange review for bleeding that does not settle with firm pressure, a wound that is opening, or a lump that changes in colour, shape, or texture. These signs need assessment because an inflamed cyst and other skin problems can look similar.

Ask what features support a keratin cyst, whether removal is advisable now, how the wound will be closed, and what scar changes to expect. You can also ask how to care for the site, when normal activities can resume, and what to do if another lump appears.
