SARKOMA (az yunoni zagkoch — gusht va osha — suffiksi nomi omosho), omosi badasl (khabis, khavfnok)-est, ki dar boftahoi payvastkunanda ba vujud meoyad. Sarkoma du khel meshavad: 1) Sarkomae, ki az boftahoi payvastkunandai janini (mezenkhima) paydo meshavad — mezenkhimoma; 2) Sarkomae, ki az boftahoi mezenkhimii bolig padid meoyad — Sarkomai ustukhoni (osteosarkoma), tagoyaki (kh o n d- rosarkoma), ragi (angiosarkoma), khunofar (retikulosarkoma), mushaki (leyomiosarkoma, rabdomiosarkoma) va juzhoi takyagohii asabiya (gliosarkoma).
Sarkoma qarib 10%-i hamai omoshoi badaslro tashkil doda, dar baze mamlakathoi Afrika va Osiyo nisbatan beshtar pahn shudaast. Dar bayni Sarkoma az hama ziyodtar omosi us- tukhon, bad omosi boftahoi narm (mushak, ragho, asab) va az hama kam Sarkomai uzvhoi khunofar mushohida meshavad. Az rui khususiyathoi gistomorfologi niz Sarkomaro ba yakchand namud judo mekunand: Sarkomai mudavvarhujayra, Sarkomai hujayraash gunogunshakl,Sarkomai khujayraash dukmonand (hamaashon az rui andozai hujayra farq mekunand) va fibrosarkomaho (dar in namudi Sarkoma juzhoi nakhmonand nisbat ba juzhoi hujayravi bartari dorand). Khususiyati hamai omoshoi badasl dar boftahoi atrof sabzida onhoro nobud kardan ast. In khususiyat dar Sarkoma ravshantar zohir megardad.
