Dear X: Testicular tumors are common in older intact males, but there
is no way to tell without examination - Sertoli cells, seminomas, and
interstitial cells are all about equal in prevalence.
 
The preputial mass should also be removed ASAP - the chance of a malignancy
is higher here than in any other place on the male's skin, and the earlier
removed, the better.  Don't delay surgery for results on the blood - pull
it on the way to surgery.
 
I would be interested in reviewing the tissues (especially the testis)
at no charge, of course.  Testicular tumors are not very common and I am
always interested in adding another one to the archive.
 
With kindest regards,
