Hemorrhages 



Hemorrhages into the various tissues of the ovary are not uncommon. 

 This condition is found most frequently associated with the acute fevers, 

 but occasionally the condition develops independently of any known cause. 

 In these cases of hemorrhage the condition may arise as a diffuse hemor- 

 rhage into a recent .corpus luteum and extravasation into the peritoneum, 

 or the condition may give rise to a diffuse extravasation of blood into all 

 the tissues of the ovary, destroying all the Graafian follicles that have be- 

 gun to mature by invasion of the cavities of these and destruction of the 

 ova. It is probable that the hemorrhages give rise to only a temporary 

 check to the normal functioning of the ovary. 



New Growths of the Ovary 



As stated above, the human embryo is made up of two types of tissues 

 of similar origin, the interstitial tissues and the glandular tissue. It is 

 doubtful whether in the adult these tissues having once been differentiated, 

 can ever take on the other's function (interchange of function). 



The tumors of the interstitial tissue are interesting from the point of 

 view of their varied morphology. In the one tumor one may find tissues 

 closely resembling sarcoma, perithelioma, endothelioma, and carcinoma. 

 Among solid tumors the mixed variety is most common. The perithelio- 

 mata predominate. This protean property of the interstitial cell is trace- 

 able, I think, to its origin from the germinal epithelium, and as such it 

 possesses potentialities which we do not find in other cells. In the lower 

 animals these interstitial cells can, in exceptional cases, even take on the 

 characters of oogenesis and mimic the normal process so closely indeed 

 as to easily deceive the unwary student. 



The oogenetic tissues of the ovary give rise to a very large variety of 

 new growths, greater indeed and more varied than those of any other 

 organ. This again, I think, is due to the great potentials of these cells 

 which have had impressed upon them the power of reproducing the many 

 and varied tissues that compose the human body. The structures from 

 which these tumors arise are the ova and follicles and the fetal remnants 

 of the germinal downgrowths. 



These structures can and do give rise to growths of almost every nature 

 and by their very nature they can give rise to very mixed growths. The 

 cystic growths are most frequently largo and may be lined with any kind 

 of secretory surface. The contents of the cysts vary with the character 

 of the lining cell. Cysts usually destroy all ovarian activity of a high 

 order and the ovarian stroma becomes stretched out over the surface of
