TESTIS - Seminoma

The testis is grossly enlarged by a tumour which is homogeneous, except for areas of haemorrhage. The testicular capsule appears intact.
A sudden increase in the size of the right testis was reported at the age of 10 years. The testis was removed and the owner reports that the dog has suffered no untoward effects and is still fit and well at the age of 12 years.
