Included with the sarcomata are malignant tumors which spring from theadventitial connective tissue immediately surrounding the ovarian blood-vessels (perithelioma) and from the endothelium lining the blood- and lymph-vessels (endothelioma). These tumors closely resemble the round-cell sarco- NEW GROWTHS 353 mata and, clinically, need hardly be distinguished from them. They are fre-quently cystic. In general, the sarcomata can be macroscopically differentiated fro
