CANCEKOUS TUMORS. 31 



I add a couple of illustrations from a larger and more luxu- 

 riant growth of the same region. The patient was a man aged 

 forty-three, who died in Providence Hospital, in April, 1871, 

 after an illness of about two years. (See Medical Section, 

 Army Medical Museum, No. 1091.) At first the S3'mptoms 

 were those of indigestion, then obstinate vomiting set in, 

 finally a tumor could be felt in the epigastric region, the dis- 

 ease was recognized, and ran its usual course. 



The pyloric half of the stomach was involved in the morbid 

 growth, which presented itself as an irregularly lobulated 

 thickening and induration of the coats, in places an inch in 

 thickness. The stomach was adherent to the liver, into the 

 substance of which the carcinomatous infiltration extended, 

 and between the two the mass had softened, forming an 

 abscess-like cavity which communicated with the interior of 

 the stomach by an ulcerated opening through which the fluid 

 contents of the cavity had escaped. The pyloric orifice itself 

 w^as not much thickened. 



Now the structure of the thickened stomach in this case 

 was almost precisely like that of the last, except that the cyl- 

 inders were as a rule larger, and that there was an abundant 

 small-celled infiltration between the fibre-cells of the muscular 

 coat. (Two photographs, Nos. 65 and 66, shown.) 



These two growths represent, so far as I am at present in- 

 formed, the most common type of cancer of the stomach, and 

 if you picture in your minds the condition which would re- 

 sult if fluid should accumulate in some of the cjdinders of such 

 a growth, distending them into cyst-like forms, you would 

 have a correct idea of a somewhat rarer form of cancer of the 

 stomach described in the books, of which, however, we have as 

 3'et no example in the microscopical collection of the JMuseum. 



The last case to which I shall call your attention is one of 

 primary cancer of the ovary which illustrates this very point 

 of cystic development. The patient was supposed to be suf-
