What should you know about tiny sebaceous cyst?

People often call these lesions sebaceous cysts, although many are epidermoid cysts. They can feel smooth, round, and mobile under the skin, sometimes with a tiny central opening. A cyst may be painless when quiet. If its lining becomes irritated or the contents trigger inflammation, the area can turn red, swollen, tender, or foul-smelling. A skin lump has several possible causes, so a new or changing lesion should be examined rather than diagnosed by squeezing it.

Leave the cyst alone, keep the skin clean, and use a warm compress if it feels mildly tender. Do not pierce, cut, or force material out at home; this can introduce infection and leave a scar. If the cyst repeatedly returns, catches on clothing, or bothers you, a clinician can discuss Cyst Removal. An inflamed lesion may need a different plan, such as a Steroid Injection Into The Skin or, when infection has collected, Abscess Drainage.

Book an examination if the lump grows, becomes painful, changes colour, drains, or keeps recurring. Seek prompt care for spreading redness, marked warmth, fever, red streaks, or rapidly increasing swelling. A lump near the eye, nose, or another sensitive area warrants professional advice before any procedure. Urgent assessment is needed if severe pain or illness develops.

Does this lump have features of a cyst? Is it inflamed or infected? Should it be observed or removed? What procedure would address the cyst wall as well as its contents?
