RNDOTHELIAL TUMORS—ZEIT. 569 the living tissue, but must depend on interpreting theseprocesses from histologic examinations. In the endo-thelial tumors we compare the parenchyma with normalendothelium just as we divide epithelial tumors histo-genetieally by comparison with normal squamous andcylindrical epithelium into two classes. Here also ourdiagnosis lacks exactness at limes, because we are un-able to decide whotlier wc are dealing with squamous. Fig. 5.— intravasculare of uterus.
