What is a Lipoma?

A lipoma is a soft, round, non-cancerous growth of fat cells encapsulated in a thin fibrous layer. Lipomas commonly appear on the neck, shoulders, back, arms, and thighs. Most are painless and grow slowly.

Symptoms

  • Soft, doughy lump under the skin
  • Freely movable when pressed
  • Usually painless
  • Slow growth over months to years
  • May occasionally cause discomfort if pressing on nerves or growing large

When to See a Specialist

  • Any new lump under the skin
  • Rapid growth or change in a known lump
  • Pain associated with a lump
  • Cosmetic concern
  • Multiple lumps

Diagnosis

  • Clinical examination is usually sufficient
  • Ultrasound for deep or atypical lumps
  • Biopsy in select cases to confirm benign nature

Treatment

Watchful Waiting

For small asymptomatic lipomas.

Surgical Excision

For symptomatic, cosmetically concerning, or large lipomas.

  • Anaesthesia: local (most cases) or short general
  • Duration: 20 to 45 minutes
  • Same-day discharge
  • Small scar at excision site
  • Recovery: return to office work in 1 to 3 days

Recovery

  • Keep the area clean and dry
  • Sutures usually removed at 7 to 10 days
  • Return to physical activity: 1 to 2 weeks
