the irritation of retained smegma or gonorrheeal discharge. Retraction 
of a narrow prepuce behind the glans penis, with consequent strict- 
ure, may produce an inflammation sometimes followed by gangrene. 
Syphilitic ulcers may occur on any portion of the penis. Inflamma- 
tion of the corpora cavernosa produced by any cause may result in a 
fibrous induration of the part. 
What tumors occur on the penis ? 
Papillomata, fibromata, lipomata, angiomata and carcinomata. 
What are the lesions of the scrotum ? 
Those common to skin elsewhere are found here also. A condition 
of elephantiasis may occur, which consists of a growth of new connective 
tissue and a dilatation of the lymphatic vessels in the skin. The new 
growths that have been observed here are as follows: Fibromata, lipo- 
mata, sebaceous and dermoid cysts and epitheliomata. 
TESTICLE. 
What forms of inflammation are found in the testicle ? 
Acute orchitis. 
Chronic orchitis. 
Tubercular orchitis. 
Syphilitic orchitis. 
Describe acute orchitis. 
It is an exudative inflammation. The organ is swollen, congested 
and infiltrated with serum or pus. The inflammatory products may be 
absorbed or abscesses be formed which may undergo cheesy or calca- 
reous degeneration. The abscesses may open externally and healing 
take place by the formation of granulation tissue. 
What changes take place in a chronic orchitis ? 
It may follow the acute process or occur as an independent condi- 
tion. There is a marked increase of interstitial connective tissue with 
an atrophy of the seminiferous tubules. Or the walls of the tubules 
may be thickened and they may be converted into fibrous cords. The 
tunica albuginea may be thickened or the whole testicle may be con- 
verted into a mass of fibrous tissue. 
What changes are seen in tubercular and syphilitic orchitis ? 
Both these forms of inflammation show the peculiar changes com- 
mon to the same types of inflammation as heretofore described.
