What is Myxofibrosarcoma?
Also known as...
- MFS
- Myxofibroblastic sarcoma
- Myxoid MFH: (old name – no longer used)
- Myxoid malignant fibrous histiocytoma (old name – no longer used)
Often seen as a painless, slow growing lump, MFS tumours tend to form in the connective tissues of the arms and legs close to the surface although they may be found deeper into the tissue. The name reflects a mixture of myxoid, or mucous containing cells and cells that look like fibrous connective tissue. They have many different genetic mutations which means tumour sequencing techniques are less useful in making a firm diagnosis.
MFS can return aggressively after surgery, so surgery often takes a wide margin of tissue and is combined with radiotherapy.
How rare is it and who does it affect?
Myxofibrosarcoma is one of the more common sarcomas, affecting 2-3 people per 100,000 each year.
Myxofibrosarcoma usually affects older people, typically over 60, but cases are occasionally seen in younger people. There are slightly more cases in men than in women.

We are proud to partner with Sarcoma UK
We are delighted to have partnered with Sarcoma UK, a charity that supports those affected by soft tissue and bone sarcomas. Growing our own community of members with sarcoma diagnoses will allow us to build a resource for reseachers which will make it easier for them to find participants for clinical trials and other research.
