Detailed Description:
A lipoma is a fatty lump typically located on the trunk, shoulder, arms or legs. For the purposes of this study, only lipomas on the trunk, arms, legs, or neck were treated. (Lipomas on the face, wrists, hands, lower portion of the spine, genitals, ankles, or feet were not treated.)
  Eligibility

Genders Eligible for Study:   Both
Accepts Healthy Volunteers:   No
Criteria

Inclusion Criteria:

    • History of slow growth followed by dormancy, and stable for at least 6 months.
    • Greatest length by greatest perpendicular width between 1 and 16 square centimeters, inclusive
    • Discrete, oval to rounded in shape, not hard or attached to underlying tissue
