A lipoma is a growth of fat cells encapsulated in a thin, fibrous sac usually found just below under the skin. They can be found on any part of the body including torso, head, neck, upper thighs, upper arms, and armpits. When a lipoma occurs on the back of the head or the neck it is called “buffalo hump”.

Lipomas are the most common noncancerous soft tissue growth:

  • Slow growing, fatty lump
  • Mobile and “squishy” to the touch
  • Not usually tender
  • Most common in middle age
  • Some have more than one at a time
  • Harmless and can go untreated
  • If a lipoma is bothersome, painful, or growing, it can be removed.
