What should you know about sebaceous cysts all over the body?

The term sebaceous cyst commonly describes epidermoid cysts, which are sacs under the skin containing keratin. Multiple lumps may occur in different areas, and they may not all be the same thing. Some are small and quiet; others become sore after rubbing or inflammation. A clinician can compare their texture, mobility, skin openings, and distribution. A useful starting point for understanding different kinds of lumps is [Skin Lumps](/symptoms/skin-lumps/).

Make a simple record of where each lump is, when you noticed it, and whether it changes, hurts, or drains. Do not squeeze or puncture them, since this can spread irritation and make later assessment harder. Comfortable clothing and gentle skin care can limit friction. If one cyst is repeatedly troublesome, [Cyst Removal](/treatments/surgical-dermatology/cyst-removal/) may be discussed. A painful flare may be considered for [Steroid Injection Into The Skin](/treatments/injectables/intralesional-steroid-injection/) after an examination.

Arrange a medical review when lumps are appearing quickly, changing, or difficult to distinguish from one another. Seek prompt attention for a lump that becomes hot, rapidly swollen, very tender, or associated with fever or spreading redness. A collection of infected material may need [Abscess Drainage](/treatments/minor-procedures/abscess-drainage/).

Do the lumps have the same appearance and texture? Should any be examined more closely? Could a family tendency or skin condition be relevant? Which ones need treatment, and how should I monitor the rest?
