This is the list as it stands at the moment. I understand that some of them may be redundant in the fact that a certain kind of sarcoma could possibly be known by more than one name, or have previously been known by one name included here, plus it’s new name. Also, some may be subtypes of one kind of primary tumor. I haven’t had enough research time to study the differences, whether in molecular appearance, genes, or whatever. My primary sources were World Health Organization and Pubmed. Secondary sources listed below.
