Editing Sarcoma (section)

== Classification ==
Sarcomas are typically divided into two major groups: [[bone sarcoma]]s and [[soft-tissue sarcoma]]s,<ref name=":1">{{Cite book|title=Cancer and its Management | edition = Seventh | vauthors = Tobias J |publisher=John Wiley & Sons, Ltd.|year=2015|isbn=978-1-118-46875-3|location=Chichester, West Sussex, PO198SQ, UK|pages=446}}</ref> each of which has multiple subtypes. In the United States, the American Joint Committee on Cancer (AJCC) publishes guidelines that classify the subtypes of sarcoma.<ref name=":0">{{Cite book|title=AJCC Cancer Staging Manual, Eight Edition| vauthors = Amin MB |publisher=Springer International Publishing AG Switzerland|year=2017|isbn=978-3-319-40617-6|location=Chicago, IL|pages=471–548}}</ref> These subtypes are as follows:

===Subtypes of bone sarcoma===
* [[Osteosarcoma]]
* [[Chondrosarcoma]]
* Poorly differentiated round/spindle cell tumors (includes [[Ewing sarcoma]])
* [[Hemangioendothelioma]]
* [[Angiosarcoma]]

* [[Adamantinoma]]
* Other:
** [[Liposarcoma]]
** [[Leiomyosarcoma]]
** [[Malignant peripheral nerve sheath tumor]]
