Lipoma is a type of tumor on the body surface, commonly found in the limbs and subcutaneous areas. It generally presents as a mass under the skin, which is lobulated or flat in shape, with no swelling or redness on the surface skin. Clinically, once a lipoma is diagnosed, surgical removal can be considered. If the lipoma's capsule breaks during surgery and the lipoma is damaged, there is no need for particular concern. It is only necessary to completely remove the lipoma, as it is composed of fatty tissue, the same as the normal subcutaneous tissue, and does not lead to serious consequences.
