STUDIES ON PATHOLOGIC OVA. 



of decidua marked off on the inside by a pronounced 

 zone of fibrinoid substance. 

 (6) Decidua not infiltrated. 



No. 735. 



(1) J. R. Blackman, Hastings, Nebraska. 



(2) A 50X40X30 mm.; B 4 mm. 



(3) First pregnancy of a woman, aged 30 years, who 

 was married January 10, 1912. Last menstrual period 

 May 29 to 31, and abortion July 20 following. Cervix 

 dilated July 19 and a strip of gauze inserted in the uterus. 

 Abortion induced for pernicious vomiting. Last periods 

 were less profuse. Right ovary adherent and tender over 

 McBurney's point. Frequent pain in appendix region. 

 Uterus not infected. 



(4) Pear-shaped mole 50X40X30 mm., with very 

 thick walls and well filled with granular magma, which 

 peels out in the form of large clumps. The cavity con- 

 taining the magma measures 25X20 mm. On one side 

 was seen a small whitish, amorphous body, about 4 mm. 

 in length, the remnant of the embryo. 



(5) The chorionic wall is thin and lined with a dense 

 mass of granular magma containing embryonic fragments. 

 It is surrounded by necrotic villi which are embedded 

 in a mass of fibrin, mucoid substance, and some blood. 

 The surrounding fibrinoid substance and decidua are very 

 thin. There are numerous syncytial buds at points; 

 otherwise most of the trophoblast is necrotic. The embry- 

 onic mass proved to be a macerated fragment of an embryo. 

 It includes a section of precartilage and spinal cord, and 

 is closely embedded in granular magma. No amnion was 

 found. The decidua is necrotic, but not infiltrated. 



(6) Decidua very degenerate, but apparently not infil- 

 trated. 



No. 740. 



(1) Ira L. Fetterhoff, Baltimore, Maryland. 



(2) B 56 mm. 



(3) Patient 44 years old; married in 1890. Six preg- 

 nancies: First ended at term; second and third in abor- 

 tions; fourth, twins; fifth at term; sixth, this abortion. 

 Menstruation in April 1913, continued 6 weeks; again 

 July 16 to 23; abortion August 8 following. After careful 

 examination uterus found to be apparently normal. 



(4) The embryo has a clubfoot, but otherwise is nor- 

 mal. It is encircled by a mass of magma which has 

 cemented the extremities together, making it look like 

 a mummy. The cord is very thin and twisted. No mem- 

 branes \vere received with the specimen. 



(6) Decidua and chorion absent. 



No. 743. 



(1) John H. Groshans, Baltimore, Maryland. 



(2) B 105 mm. 



(3) Patient 34 years old; married June 1, 1907. One 

 birth at term, July 1908; abortion at 4 months, June 1910. 

 Last menstrual period March 8 to 16, 1913, and abortion 

 August 17 following. Patient supposed to use abortives, 

 but denies it. No venereal diseases. Patient is a second 

 wife. Husband's first wife had 7 children and 3 abortions. 



(4) The specimen is shriveled, as if it had been in 

 alcohol for some time, but the body and extremities are 

 normally formed. The frontal bone is greatly retracted 

 and the parietal bones overlap. The ears are flattened 

 out and the eyes are sunken, all of which make it appear 

 as an early stage of fetus compressus. 



(6) Decidua and chorion absent. 



No. 797. 



(1) George T. Tyler, Greenville, South Carolina. 



(2) A 65X35X35 mm.; B 35 mm. 



(3) Woman aged 29 years; married one year. Always 

 has had painful menses, which have been profuse. This 

 was especially so in the last period, 4 weeks before the 

 present one, November 9. History of exertion just before 

 this period began. The patient did not know she was 



pregnant, as she had missed no periods. Physician called 

 on November 9 because of pain and bleeding, and he found 

 specimen presenting at vaginal orifice. No previous 

 history of importance. 



(4) The specimen is covered with a few atrophic villi, 

 and its wall is thin on one side and thick on the other. 

 The interior is filled with a jelly-like magma and contains 

 an atrophic embryo 35 mm., which is markedly deformed, 

 having atrophic hands and feet and a very thin umbilical 

 cord. The head is also reduced in size. 



(5) Sections of the chorion show that it is hemorrhagic 

 and inflamed. The chorionic wall is fibrous and degenerate, 

 and the villi mostly necrotic, only a few of them being 

 fairly preserved. They are bound together by fibrin and 

 a great deal of fibrinoid substance. There is also con- 

 siderable nuclear dust. 



(6) Marked infiltration of the decidua; probably luetic. 



No. 805. 



(1) Morris A. Birley, Thurmont, Maryland. 



(2) A 100X60X45 mm.; B 50 mm. 



(3) Woman aged 31 years; married 16 years. Seven 

 births at term, this being her first abortion. Last period 

 September 2 to 5; abortion December 5 following. Badly 

 lacerated os. Patient belongs to a very fertile family. 



(4) The chorion, which measures 100X60X45 mm,, 

 has a smooth wall, the greater part of which is thickened 

 and hemorrhagic. One end, however, is thin and trans- 

 parent. When the specimen was halved it was found to 

 contain a cavity 70X50X25 mm., lined by a smooth 

 amnion containing a fetus CR 50 mm., normal in shape 

 but macerated, with numerous edematous blebs of skin. 

 The umbilical cord is very thin and extremely twisted. 



(5) Sections show that the amnion and chorionic wall 

 are fibrous, and surrounding the latter are numerous villi 

 packed together and intermingled with a great quantity 

 of fibrinoid substance, organized blood, decidua, and 

 inflammatory patches. There also is a great deal of 

 nuclear dust. The spheres of trophoblast so frequently 

 seen in these specimens have undergone fibrinoid changes. 



(6) Marked infiltration of the degenerate decidua. 



No. 809. 



(1) O. S. Lowsley, New York. 



(2) A 50X30X30 mm.; B 22 mm. 



(4) The abortion mass, which is composed mostly of 

 chorion, measures 50X30X30 mm. The amnion pro- 

 trudes and contains a badly macerated embryo 22 mm. 

 GL. This is distorted and bent upon itself, but when 

 straightened appears to be normal in form. 



No. 811. 



(1) George H. Hocking, Govans, Maryland. 



(2) A 100X80X60 mm.; B 120 mm. 



(3) Patient aged 40 years; married 1896. Six preg- 

 nancies, five at full term and one abortion. Last men- 

 strual period May 12 to 17; abortion December 26 fol- 

 lowing. Beginning about October, there were slight 

 losses of blood at intervals for several weeks, and it is 

 fair to assume that gestation ceased even earlier than this. 

 Patient one of 6 children. The specimen is bent markedly 

 upon itself; the epidermis is mostly lacking and the cord 

 is greatly twisted. The fetus measures 120 mm. 



(5) The amnion and chorion are very fibrous and 

 closely connected by a thick layer of reticular magma. 

 The chorionic wall is closely covered with decidua, there 

 being no villi in the portion cut. One of the hands of the 

 embryo was cut into sections. The tissues do not stain 

 well. 



No. 828. 



(1) Austin Miller, Porterville, California. 



(2) A 50X30X16 mm.; B 8 mm. 



(3) Patient aged 28 years; married 3 years. One 

 previous pregnancy, which ended at term. Last men-
