Posttraumatic lipomas: where do they really come from?

A series of nine patients is reported in which a subcutaneous lipoma appeared
within a few months after a blunt trauma. Computerized tomography and/or nuclear
magnetic resonance and/or echography were employed for the diagnosis in addition
to physical examination. Surgical removal of the masses was then performed
without any recurrence at the 3-year minimum follow-up. In four cases,
suction-assisted lipectomy was employed to minimize the scarring. However, in
these cases a biopsy was first performed to rule out malignancy. The
pathogenetic mechanisms of posttraumatic lipomas are reviewed in the literature
and are found to be incompatible with some of the cases presented. Instead, the
hypothesis of a true adipose tissue neoformation following trauma is suggested.
