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.)
