720 REPRODUCTIVE ORGANS OF THE MALE. 



The epithelium lining the tubules may be fatty, disintegrated, and peeled 

 off, or it may have largely disappeared. The lumen of the tubules may 

 be filled with a granular, nucleated mass which in transverse sections 

 looks like a giant cell. The thickened walls of the tubules may be in- 

 filtrated with small spheroidal cells, so that the underlying stroma is 

 scarcely visible. When this occurs in connection with a similar infiltra- 

 tion of the interstitial tissue and the formation of giant cells in the luniina, 

 we have structures which present the greatest resemblance to some forms 

 of tubercle grauula (Fig. 474). 



Tuberculous inflammation may extend from the testis to the vas def- 

 erens, vesiculse seminales, and prostate. 



Syphilitic Orchitis. This may occur in the form of a diffuse new forma- 

 tion of connective tissue, which may be localized or be widely distributed. 

 This organ becomes dense and firm. Morphologically there is no differ-

 other excitants. It may occur in children affected with congenital 

 syphilis. Gummata may form in connection with the interstitial indura.

 In leprosy, inflammatory foci in the testicle are common. 1 



TUMORS. 



Fibromata occur in the form of small dendritic or polypoid growths of 

 the visceral layer of the tunica vagiualis. These sometimes become free 

 and are found in the sac, usually in connection with hydrocele. Small 

 nodular fibromata occasionally occur in the albugiuea and in the sper- 

 matic cord. 



Lipoma, either pure or in combination with myxoina and sarcoma,
