Clinical Definition

A lipoma is a benign encapsulated neoplasm, which usually has a soft, rubbery consistency. It is composed of mature adipocytes. Lipomas are usually located in the subcutaneous layer of the skin. They are usually painless and most often do not require treatment. 


In Our Own Words

A lipoma is a non-cancerous, abnormal mass made-up of fatty tissue. Lipomas often develop below the surface of the skin. A lipoma may form anywhere on the body, but are most commonly found under the armpits and on the shoulders, trunk and neck. In most cases, lipomas do not cause pain or require treatment. If they become very large, one can choose to have them removed.
