nective tissue cells; granvilation tumors are composed of 

 verv similar embryonal cells ; hence, the latter are some- 

 times called sarcomas. It may be that an examination of 

 these secondary granulation tumors has led some observers 

 to classify the common skin tumors under the head of sar- 

 comas. 



The common skin tumors are frequently called warts, and 

 this mistake is due to the fact that many persons designate 

 all surface tumors as warts. 



The wart is technically called a papilloma ; its prototype 

 is the papillae of the skin. The connective tissue sends ap 

 papillae which become greatly enlarged and are supplied 

 with a network of blood vessels from the subcutaneous 

 connective tissue. These enlarged papillae become sur- 

 rounded with epithelium which varies in character with the 

 location ; foi instance, if the papilloma is on the skin it is 

 surrounded with flat scale-like epithelium, but if it is on a 

 mucous membrane it is surrounded with a thinner and more 

 delicate capsule. The papilloma (wart) of the skin is 

 usually much smaller and less vascular than the skin tumors 

 of fibromas. In some instances it may require a micro- 

 scopical examination to determine whether a tumor is one 

 of these fibromas or a papilloma. 



Teeatment. 



1. Surgical. — First, cut away the long matted and filthy 

 hair around the tumor ; clean the tumor and the surround- 

 ing skin with soap and water and then apply some anti- 

 septic ; such as, a two per cent, creolin solution, or 1 to 1000 

 mercuric chloride solution. Take the knife in the right 

 hand, cut the skin from around the tumor, preserving as 

 much of the skin as possible, but taking great care to re- 

 move completely all of the morbid growth. In most cases 

 where the skin has not been broken, the tumor will pop out 

 as soon as an incision is made through the skin and the 

 capsule, and a little pressure is applied. In other cases, 

 the knife must be used to remove the tumor from its at-
