There arc good reasons BENIGN NEOPLASMS OF THE UTERUS. 587 for upholding the latter view, especially because of the presence of hsema-toblasts or undeveloped red blood-corpuscles within the medullary it is fully admitted that Rokitanskys assertion, made fifty yearsago, that the formation of red blood-corpuscles precedes the formation ofcavernous angioma, is correct. How peculiar the outcome of obliterationof a cavernous vein may be is shown in Fig. 26. Here the convolutionsof the waxy rim are so pronounced that one is almost compelled to believethat the vein was collapsed and empty before the process of obliterationbegan. The convoluted rim here is but faintly striated, and contains alimited number of branching protoplasmic or fibrous tracts. This means Fia. Obliterated vein, x 200.—H, H, hyaline convoluted tracts; C, medullary and fibrous tissue between theconvolutions; M, U, smooth muscle-bundles of uterus; 0, obliterated capillary or artery. a high grade of waxy infiltration. Between the convolutions we noticetracts of medullary tissue intermixed with fibrous connective tissue. Thesupply of this tissue with capillary blood-vessels is small. The wholeformation is surrounded by a zone of medullary tissue directly borderingupon unchanged smooth muscle tissue. In the left upper corner we noticea waxy patch, evidently an obliterated capillary or artery. What the waxvrim is can lie determined only with higher powers of the microscope. From a histological stand-point I would not hesitate to compare the 588 BEXIGX NEOPLASMS OF THE UTERUS. waxy rims of the cavernous veins with an anomalous formation of carti-laginous tissue in certain chondromata.
