An uncommon but very malignant cancer of the bone in children and young adults, the condition was ?rst identi?ed as being di?erent from OSTEOSARCOMA by Dr J Ewing in 1921.

n. a genus of parasitic protozoans (see Sporozoa) that infect birds, reptiles, and herbivorous mammals. S. lindemanni, which occasionally infects humans, forms cylindrical cysts (sarcocysts) in the muscle fibres. In heavy infections these cysts can cause tissue degeneration and therefore provoke muscular pain and weakness. Sarcocysts have, in the few positively diagnosed cases, been located in the heart muscles, arm muscles, and larynx.... sarcocystis
