As the number of cells increases the chan-nels become obstructed and form the plexiform collections with which the processseems to start, and the cells extend into the surrounding tissue in which they fade awayor are lost. The cellular character of the tumor is in proportion to the original numberof vascular elements. If they are few, there will be few, but often large ramifyingcollections of cells; if many, the cell masses may be so closely approximated that theentire tissue becomes cellular and the derivation of the cells difficult to determine. Of the degenerative conditions that occur in sarcoma, there are two that modify theterminology—mucoid degeneration and pigmentation of the Enormous cysto-sarcoma of the breast. (Graefe.) Mucoid or myx-edematous change in sarcoma is very common and presents itselfin two different forms: First, in localized areas of the tumor tissue that melt awayinto a liquid jelly, forming colliquation cysts without well-defined walls; second, in theform of a mucoid change of the cells that seems to be common to them all, and to havenothing to do with nutrition. The first is an accidental circumstance, the second afundamental characteristic of the cells. The first can occur in any kind of sarcoma orother connective-tissue tumor; the second can only obtain when the cells themselves areor have become myxoblasts. In the first the cells die and the mucinoid substance seemsto be a product of their autolysis; in the second the cells produce the mucinoid substancewhile alive and multiplying. The second alone is the true myxosarcoma. Every modern writing upon the subject contains m
