Recognising a lipoma
a soft, regular lump, mobile under the fingers, which grows slowly over months or years;
usually painless (some forms may be tender);
highly variable in size, from a few millimetres to several centimetres.
An important point: any lump that grows rapidly, becomes hard, painful or fixed, or exceeds several centimetres warrants prompt medical advice and, if necessary, imaging. This is one of the reasons why the removed specimen is systematically analysed.
Why remove it?
Excision of a lipoma is considered when it:
causes functional or mechanical discomfort (pressure, rubbing, belt, strap);
becomes visible or unsightly;
increases in size;
or when diagnostic doubt warrants its analysis.
The procedure
Local anaesthesia as day surgery for most lipomas; deeper anaesthesia may be proposed for large, deep or multiple lipomas.
An incision placed as far as possible within the natural creases of the skin, of a length adapted to the lump.
Complete removal of the lipoma with its capsule, then closure with sutures, sometimes with a lightly compressive dressing.
Systematic histopathological analysis of the specimen.
The procedure takes from 20 minutes to an hour depending on size and depth.
Recovery and healing
Recovery is straightforward: moderate discomfort for a few days, a dressing for one to two weeks, and a rapid return to usual activities (sport involving the area waits until healing is complete). A small fluid collection or temporary firmness of the operated area may be observed and resolves gradually. The scar fades over several months.
