Symptoms of Lipoma
Lipomas can occur anywhere in the body but most commonly occur in the neck, shoulders, back, abdomen, arms, or thighs. Signs and symptoms that a lump might be a lipoma include:
- Soft, doughy consistency
- Easy mobility with slight finger pressure
- Small size, usually less than 2 inches in diameter (but may grow quite large over time)
- Pain, if the lipoma grows and presses on nearby nerves or if it has many blood vessels
Diagnosing Lipoma
Our experienced dermatologists, facial plastic surgeons, and plastic surgeons will conduct a thorough evaluation, which includes a:
- Physical exam
- Discussion of personal and family medical history
- Discussion of symptoms
We can often diagnose a lipoma with this information, but we sometimes recommend further testing. This commonly involves special X-rays that allow the boundaries of the lipoma to be better determined. Rarely, further investigation is necessary to rule out cancer. Liposarcomas – cancerous tumors in fatty tissues – grow rapidly, don't move when touched, and are usually painful.
Further testing might involve:
- Biopsy: Removal of a small tissue sample to examine under a microscope for signs of cancer
- Imaging: An X-ray, MRI scan, or CT scan if the lipoma is large, has unusual features, or appears to go deeper into the muscle layer
Treatment for Lipoma
At UT Southwestern, our dermatologists and cosmetic and plastic surgeons typically recommend monitoring the lipoma if it’s small and not growing. If the lipoma grows large or begins to cause pain or other problems, it can be removed. Our procedures to remove a lipoma include:
- Surgery: Our surgeons can take out a lipoma with a small cut made after an injection to numb the area. A technique known as minimal excision extraction can result in less scarring. People usually go home after the procedure, without the need for a hospital stay.
- Liposuction: This treatment uses a special instrument to evacuate the fatty tumor with small incisions. Liposuction is reserved for very large lipomas to help minimize the scarring. When liposuction is used, there is the possibility that the lipoma may return in the distant future.
Giant lipomas (larger than 2 inches) may cause pain because they press on or grow into nearby nerves. We typically remove giant lipomas in an outpatient procedure, but patients might need anesthesia to make them sleep during the procedure.
