. The breast: its anomalies, its diseases, and their treatment . hy or infiltration with tumor cells, but, as a rule, enough of it remains to make iteasy to determine upon what condition the new neoplasmic process was engrafted. The structure of the sarcoma tissue varies greatly for reasons not yet tumor is composed entirely of small round cells resembling lymphocytes but withmore cytoplasm than lymphocytes ordinarily possess; another is made up entirely ofspindle cells, sometimes small, sometimes large; a third seems to be composed of cellsof both round and spindle shape; other tumors have cells of no particular shape. Itsome round-cell tumors, and in more spindle-cell tumors, giant cells are the type of the cells of which the tumor is composed is used to define itsspecies. Thus, round-cell sarcoma, spindle-cell sarcofna and giant-cell sarcoma are thethree chief types. Tumors occur in which the cells are both round and spindle in shapeand others in which they are of no particular shape. It is a question why there. Fig. -Round-cell sarcoma of the breast which had broken through the skin and given rise torepeated hemorrhages. (Stewart, Jefferson Hospital.) should be a special group of giant-cell sarcomas, seeing that though such contain largenumbers of giant ceUs, they are really and chiefly composed either of round or spindle cells. It has also been found necessary to supplement these main groups by others thatprovide for other structural peculiarities. Thus, when a tumor has pigmented cells itis usually known as melanotic sarcoma, regardless of the morphology of the cells; if asarcoma contain cartilage or bone, it may be described as chondro-sarcoma or osteo-sarcoma, chondrifying sarcoma or ossifying sarcoma, regardless of its cells and othermorphological peculiarities. To endeavor to overcome taxonomic difficulties by the use of compound termshas been tried, with scant success, and specific denomination has often been lost
