Surgical treatment of multiple symmetric lipomatosis with ultrasound-assisted liposuction.

Multiple symmetric lipomatosis (MSL) is a rare disease of unknown etiology, characterized by the presence of multiple, symmetrical, noncapsulated lipomas, mostly in the neck and upper trunk. To date, there is no effective medical treatment of MSL. Surgical treatment is based on 2 options, namely, lipectomy and/or liposuction. In this retrospective study, we compare traditional lipectomy with ultrasound-assisted liposuction. Our initial experience demonstrates that the ultrasound-assisted liposuction procedure can be applied to patients with MSL, allowing simultaneous treatment of multiple areas in a single session and the removal of a substantial amount of fat, thus improving aesthetic results. If lipomas are circumscribed and isolated, traditional lipectomy is probably to be preferred.
