Lipoma or Cyst? Quick In-Office Removal

Finding a lump under your skin can be unsettling. Most turn out to be harmless lipomas or cysts. Even so, it's worth having any new or growing lump checked, and if it bothers you, removal is usually quick and done right in the office.

What is a lipoma?

A lipoma is a slow-growing lump of fat cells just under the skin. Lipomas usually feel soft and rubbery, move slightly when you press on them and are usually painless. They often appear on the shoulders, back, neck, arms or thighs.

What is a cyst?

The most common skin cysts, often called sebaceous or epidermoid cysts, are small sacs filled with a thick, cheesy material. They may have a small dark opening on the surface. Cysts can become red, swollen and painful if they get inflamed or infected, and they sometimes drain.

When should a lump be checked?

Schedule an evaluation if a lump:

• Is growing quickly or is larger than a golf ball
• Feels hard or is fixed in place
• Is painful, red or draining
• Comes back after being removed

The rare lump that isn't a simple lipoma or cyst needs a closer look, sometimes with imaging, before removal.

How in-office removal works

Many lipomas and cysts can be removed during a short office visit:

1. 1The area is cleaned and numbed with local anesthesia, so you stay awake but comfortable.
2. 2The surgeon makes a small incision and removes the lump. For cysts, removing the entire sac lowers the chance it returns.
3. 3The incision is closed with stitches, placed carefully to minimize scarring.
4. 4The tissue may be sent to a lab to confirm the diagnosis.

Most people return to normal activities the same or next day, avoiding heavy strain on the area for a short time.
