TUMOURS OF THE TESTICLE.

character, and Moiissu has only observed tumours of a type dififerent 

 from that of the testicle itself, containing tracts of carcinomatous, 

 sarcomatous, and fibrous tissue. They also appear to vary greatly in 

 gravity, for, although the cases seen by Moussu had become generalised 

 in a few months, Cruzel states that these tumours may remain stationary 

 for several years. 



The symptoms consist in progressive enlargement of the scrotal 

 region and the appearance of 

 a tumour surrounded by (Ede- 

 matous or lardaceous tissue. 



The tumour, which is con- 

 fined to one side, increases in 

 size, is bosselated and adherent 

 at points to the surface of the 

 skin, while it is insensitive or 

 only slightly painful to the 

 touch. 



In a few months it may in- 

 crease to the size of a child's 

 head. The animals have diffi- 

 culty in moving or lying down, 

 the hind limb on the affected 

 side is abducted, and the 

 animal usually lies on its 

 chest and abdomen. The 

 patient rapidly loses flesh, 

 although the appetite remains 

 good. 



When the growth is re- 

 moved, it is easy to prove 

 that the tumour has developed 

 in the atrophied mass of tes- 

 ticular tissue, and that it re- 

 mains suspended from the end 

 of the cord. 



The diagnosis of tumour 

 of the testicle is extremely easy, for the condition cannot be mistaken 

 for a haematoma or for a scrotal abscess. 



The prognosis necessarily depends on the nature of the tumour, 

 but as it is impossible to determine this point before extirpation, the 

 prognosis should always be regarded as very grave. 



Treatment. Whatever the nature of the tumour, ablation is ad- 

 visable. If it is of a benign character, recovery may be complete and
