Ford (3) reports the removal of a large teratoma from the 

 right side of the face and neck of a mulatto woman aged 40 years. 

 The tumor had been observed since the age of 18 years. It had 

 increased rapidly in size for two years prior to its removal. 



Musick(4) describes in detail a case of teratoma of the right 

 lobe of the liver, causing death in an infant of 2 months. In 

 this case structures were found having their origin in the meso- 

 derm and entoderm, but not in the ectoderm. 



Mandelbaum(5) reports a case of dermoid cyst of the medias- 

 tinum in a Russian woman of 30 years, and has collected 36 

 other cases from the literature. He suggests as a result of study 

 of the cases reported and the histological findings in his own case 

 that these growths be classified with the teratomata and further 

 suggests the following groupings: 



I. True dermoids containing only ectodermal structures. 

 II. Teratomata, dermoids with the addition of structures from the en- 

 toderm and mesoderm. 

 III. True dermoids or teratomata, with the addition of tumor formations. 



Anspach(6) summarizes the opinion of Wilms and others 

 regarding teratomata of the ovary, and reports a case of ovarian 

 teratoma with a large proportion of thyroid gland tissue in the 

 dermoid prominence removed from a woman of 36 years. 



Ewing, (7) from a study of 2 cases of testicular tumors, con- 

 cludes that teratomata of this region developing unequally or in 

 a one-sided manner give rise to the myxomata, myomata, chon- 

 dromata, carcinomata, and large round-celled sarcomata or car- 

 cinomata of the testes. 



Bergmann(8) reports 5 cases of congenital sacral teratomata 

 operated upon in children. One of the cases possessed malignant 

 characteristics with metastasis. 



CASE REPORT 



Mateo Serrer, Filipino, age 7 years. Operation, August 9, 1912. 



Family history negative. Eleven brothers and sisters died, some of 

 smallpox and some of beriberi. 



Patient was born without medical attendance; delivery was normal. 

 Child was breast fed at irregular hours, but with good success. Denti- 

 tion was normal. There were no previous diseases with the exception of 

 mild fevers. 



Present illness is congenital, a swelling having been noted under the 

 right arm shortly after birth. This swelling has increased slowly but 

 steadily in each diameter until a few days ago when the patient had a 

 slight fever and the tumor became red and increased noticeably in size. 



The present condition of the child is, in general, good. He is fairly 

 well nourished, although somewhat underdeveloped. The general examina- 

 tion is without especial interest.
