662 THE ANIMAL PARASITES OF MAN

 remained doubtful. 



Hyincnolepis diminuta, H. lanceolata, Davainea asiaiica, and Z). 

 tnadagascarensis possess no actual clinical interest ; with regard to 

 the latter it need only be pointed out that Bordier 1 in studying a 

 case of chyluria found this species in the kidneys of a person in 

 Madagascar. 



Taenia solium. 



Tcenia solium inhabits the small intestine of man ; single 

 proglottides or whole worms may get into the abdominal cavity and 

 the bladder through fistulae, and penetrating the abdominal wall 

 escape outwards or become discharged with the urine. Symptoms of 

 intestinal stenosis are certainly very rare, as in the case recorded by 

 Steinhaus 2 of a child, aged 9, the stenosis ceasing after the expulsion 

 of the segments. The usual position of the worm in the small 

 intestine is with the head closely adherent to the mucosa and the 

 proglottides lying along the intestine ; from time to time portions are 

 discharged with the faeces per rectum. Its position can also be 

 reversed, and the proglottides in the gut become thus discharged by 

 vomiting. 



The diagnosis depends upon the proglottides being generally 

 discharged in pieces in the stools, or eventually an examination for 

 eggs. Larval infection (Cysticcrcus celluloses) occurs also in man 

 through auto-infection or through food. 



Cysticercus celluloses of the skin and subcutaneous tissue occurs 

 very seldom singly ; as a rule they are found in hundreds and 

 thousands in the same individual. They occur in different parts of 

 the body, especially on the flexor surfaces of the extremities (generally 

 symmetrically), small globular swellings, the size of a pea or a hazel 

 nut, smooth, of a tough cartilaginous consistence, fairly movable 

 under the skin, in the muscles less so. They never degenerate or 

 cause the surrounding skin to lose its colour. It is an interesting 

 fact that in the case described by Possell 3 nodules on the face, 

 namely in the neighbourhood of the left cheek and behind the left 

 ear, reformed. The following are, according to Posselt, characteristic 

 for cutaneous tumours due to cysticerci : (i) the position in the 

 subcutaneous connective tissue (and almost always simultaneously 

 in the muscles) ; (2) the approximately equal size and regularly
