Malignancy is rare but can be found in a lesion with the clinical aspect of a lipoma. Liposarcoma is similar in appearance to a lipoma and appears to be more common in the retinitis, on the shoulders and lower limbs.8 Some surgeons recommend Complete excision of all clinical signs of a lipoma to rule out any possible liposarcoma, especially fast-growing lesions.8 Recently, magnetic resonance imaging has used with some success to differentiate lipomas and liposarcomas16,17.
The central skin layer to be excised is grasped with a hepatic, or Allis forceps, which is used to provide traction for removal of the tumor (Figure 3). The dissection is then performed under the subcutaneous fat to the tumor. Any tissue section is performed under direct visualization using a no. 15 scalpel or scissors around the lipoma. Precautions should be taken to avoid nerves or blood vessels that may be just beneath the tumor.
Other tumors that occur on or under the skin that could be confused with lipomas include sebaceous adenomas, mast cell tumors, hegagiosarcomas, and hegemiopericytomas. If you have questions about the diagnosis, removal may be the safest option. Sometimes, lipomas invade the connective tissue between muscles, tendons, bones, nerves or joint capsules. Called invasive lipomas, they usually occur in the legs, but can affect the chest, head, abdominal wall or perianal area.
The characteristic discovery of Dercum's disease is the slow formation of multiple painful growths consisting of fatty tissues (lipomas) that are just below the surface of the skin. The pain can range from slight discomfort when a shoot is squeezed or affected by intense pain that is disproportionate to physical results. Some affected people feel that "all the harm hurts". The pain can last for hours and can come and go or last continuously.
