A rare type of
cancer that forms in fibrous (connective) tissue, usually
in or just under the skin of the arms and legs. There may
be more than one tumor, and it sometimes spreads to nearby
tissue or to other parts of the body. Myxofibrosarcoma may
also recur (come back) after treatment. It may occur in
children, but is most common in older adults. It is a type
of soft tissue sarcoma.
