Answer

Answer

The etiology of lipsomas is unclear. The tendency to develop a lipoma is not necessarily hereditary, although hereditary conditions, such as familial multiple lipomatosis, may lead to lipoma development. Controversy exists over the so-called posttraumatic lipoma (reported cases in which minor injuries are alleged to have triggered the growth of a lipoma). However, whether the trauma caused the lipoma or simply led to the detection of a preexisting lipoma is unclear.
