Lipomas

A lipoma is a benign tumour of mature fat cells in the subcutaneous layer — soft, mobile, and usually not tender.

Lipomas — assessed at IN Eternity Clinic Singapore
In short

A lipoma is a benign lump of fat cells in a thin capsule under the skin. It feels soft and rubbery and slides under the finger, unlike a cyst, which is tied to the skin. Small, stable lipomas can be left alone; removal is a short excision under local anaesthetic. A firm, fixed or fast-growing lump is investigated first. See skin growths, lumps and bumps.

Key facts
  • What they are: benign lumps of mature fat cells in a thin capsule under the skin.
  • Key clue: a soft, rubbery lump that slides under the finger. A cyst is tied to the skin and often has a small central pore.
  • Where they appear: most often the trunk, shoulders, neck and arms.
  • Do they need removal: not always. A small lipoma that is not growing or causing symptoms can simply be watched.
  • What removal involves: surgical excision under local anaesthetic, taking the capsule so the lump is less likely to return.
  • When it is checked first: a lump that is large, deep, firm, fixed, painful or growing quickly is investigated before any cosmetic removal.
  • Assessed by: Medical Director Dr Sin Yong at IN Eternity Clinic, 9 Scotts Road, Singapore.

Mechanism

What is actually happening

Encapsulated adipocytes beneath the skin rather than within it, which is why the overlying skin moves freely and the lump moves under the finger.

The distinction

How it is told apart

Mobility is the useful sign. A cyst is tethered to the skin and often has a punctum; a lipoma slides beneath it. A firm, fixed, rapidly enlarging or painful lump is not assumed to be a lipoma at all.

Assessment

What is established first

Size, depth, mobility, rate of growth, tenderness, and number. Multiple lipomas warrant a broader look.

Approach

What is typically done

Surgical removal where size, site or symptoms justify it. Small asymptomatic lipomas are frequently left alone, and saying so is a legitimate outcome of an assessment.

When treatment waits

When it is deferred

Rapid growth, firmness, fixation to deeper tissue or pain are reasons for further investigation before any cosmetic removal is discussed.

In practice

What a consultation covers

At IN Eternity Clinic the lump is examined by hand first: its size, depth, how freely it moves, whether it is tender, and how long it has been there. Several lipomas, or a family history of them, are noted because they can point to an inherited tendency.

Where the examination is not typical of a simple lipoma, imaging such as an ultrasound scan is arranged before anything is removed, and referral is made when a specialist opinion is the right next step.

Removal

If removal is chosen

Removal is a short procedure under local anaesthetic. The lipoma is lifted out with its capsule through an incision planned along the skin's natural lines where possible, and the wound is stitched. The tissue can be sent for testing.

A scar is part of any excision, and its length depends on the size of the lipoma. Recurrence is uncommon when the capsule is removed whole.

“A lipoma slides under the skin; a cyst is tied to it. A lump that does neither is not assumed to be either.”
— Dr Sin Yong, Medical Director, IN Eternity Clinic

Frequently asked

What are lipomas?

A lipoma is a benign tumour of mature fat cells in the subcutaneous layer — soft, mobile, and usually not tender.

How are lipomas told apart from similar conditions?

Mobility is the useful sign. A cyst is tethered to the skin and often has a punctum; a lipoma slides beneath it. A firm, fixed, rapidly enlarging or painful lump is not assumed to be a lipoma at all.

What is assessed before treating lipomas?

Size, depth, mobility, rate of growth, tenderness, and number. Multiple lipomas warrant a broader look.

When is treatment deferred?

Rapid growth, firmness, fixation to deeper tissue or pain are reasons for further investigation before any cosmetic removal is discussed.

Can a lipoma turn into cancer?

A lipoma itself is benign. The concern is a different fatty tumour that can look similar, which is why a large, deep, firm or fast-growing lump is investigated before removal rather than assumed to be a lipoma.

Will a lipoma go away without treatment?

Lipomas do not usually shrink on their own. Many stay the same size for years, and leaving a small, stable one alone is a reasonable choice.
