Malignant Connective=tissue Tumors, or Sarcomata.—The sarco-mata are composed of embryonic tissue-ceUs, the intercellular substance beingvery scanty, and they resemble a process of chronic inflammation. Theydevelop from connectivf tissue, rarely have a definite stroma, and the con- 422 Tumors or Morbid (irowths stituent cells, as a rule, proliferate with great rapidity. If a sarcoma has of connective tissue, this stroma contains lymphatics and such a sar-coma infects adjacent glands. In most cases there is no connective-tissuestroma and no lymphatics. In a sarcoma without a definite stroma the blood-vessels are not surrounded by lymph-spaces and are quickly invaded by cells(B. H. Buxton). The rapidly growing forms are very vascular, the bloodflowing in vessels whose walls are very thin or running in canals lined by endo-thelium and bounded by sarcomatous cells. Such a tumor may pulsate andhave a bruit, and hemorrhage
