One particular furin of small i-Diiiul-cclled sarcoma iloserves special is the so-called hjmphoxarcoma. It is very difficult to place this tumor, forpathologists are by no means agreed as to its nature. The enlarged lymph nodesin Hodgkins disease are by some regarded as the result of a true autonomous neo-plasia, thereupon termed lympho-sarcoma: others think that the condition is asimple inflammatory tissue hyperiilasia. There is, untloulitedly, a new growth ofthe lymph nodes, which k^ads to local infiltration and the formation of distant met-astases. It has the microscoi)ical appearance of a small round-celled sarcoma(Fig. 100). Such a growth might arise from the connective tissue of the nodes (sar-coma of the lymph nodes) or by proliferation of the lymphoid elements (truelympho-sarcoma).. Fig. 99.—Small Round-Celled Sarcoma of the C\t\ ix Lteri. Winckel No. 6, without ocular. (From the authors collection.) Large round-celled sarcomata resemble closely the small-celled type and developin the same situations. They are somewhat firmer and less malignant thanthe latter. The cells are larger, richer in cytoplasm, and possess one, two, ormore large vesicular nuclei. Between the specific cells, and dividing them moreor less definitely into groups or alveoli (alveolar sarcoma), there is a delicate fibril-lated stroma containing here and there spindle and branching cells. The vesselsare generally thin-walled. Spindle-celled sarcomata are among the commonest forms of sarcomata. As arule they are firmer than the round-celled form, and may appear on section evensomewhat fibrous. Still, medullary forms occur. They are grayish or yellowishwhite in color, somewhat translucent, or, if vascular, may
