What is a low grade liposarcoma?

There are four types of liposarcoma. The most common is well-differentiated liposarcoma, low-grade tumors whose cells look like normal fat cells and grow slowly. Myxoid/round cell liposarcomas are intermediate to high-grade tumors, with the round cell being the high-grade form .

How fast does a liposarcoma grow?

Liposarcomas are also called lipomatous tumors. They usually grow slowly and do not cause pain. In some cases, they can grow very quickly and cause pressure on nearby tissue or organs.

What is Evans tumor?

Low-grade fibromyxoid sarcoma (LGFMS), also known as Evans tumor, is a soft tissue spindle cell neoplasm of probably myofibroblastic/fibroblastic origin having deceivingly bland histologic features but with metastatic potential.

Where does soft tissue sarcoma start?

Sarcoma is a type of cancer that starts in certain parts of the body, like bone or muscle. These cancers start in soft tissues like fat, muscle, nerves, fibrous tissues, blood vessels, or deep skin tissues. They can be found anywhere in the body, but most of them start in the arms or legs.
