_Diffused Hæmatocele of the Cord_ results from the rupture of some vessels of the cord, in consequence of which blood is effused within the spermatic fascia. A tumor of enormous size may be formed should the bleeding continue, or recur after having been arrested. The usual cause is some strain or violent exercise. =Varicocele= is a morbid dilatation of the spermatic veins. “The enlarged veins hang down below the testicle, and reach upwards into the inguinal canal; and when very voluminous, conceal the gland, encroach on the septum, and extend to the other side of the scrotum.” The left veins are more frequently affected than the right. In an advanced stage of the disease, the coats of the veins are thickened, and do not collapse when cut across. In cases of slight varicocele, the nutrition of the testis is not interfered with, but when large, it produces marked atrophy. Morbid Growths. =Cancer= is most frequently primary, and generally attacks the body of the testis in the first instance, the epididymis remaining for some time unaffected. _The scirrhus variety_, characterized by its great induration, is rarely met with. _Encephaloid_ is the ordinary form; it commences as one or two masses among the tubuli, which it gradually destroys. The tunica albuginea is absorbed by degrees, gives way, and allows the growth to project into the scrotum and there freely vegetate. The scrotum is slow to be involved in the disease, but at first becomes distended, sometimes to the size of a cocoanut, and then gradually ulcerates. The spermatic artery and the accompanying veins become greatly enlarged. The cord may also be attacked with the disease, while secondary cancers spring up in various places. The lymphatic glands in the neighborhood become enlarged, especially those in the iliac fossa. The inguinal glands do not generally become affected until the skin has become involved in the disease. Intermixed with the encephaloid are commonly found masses of a bright yellow color, supposed by some to be deposits of tuberculous matter, but by others, merely plastic matter undergoing fatty degeneration. _Colloid and melanotic_ cancers have rarely been observed in the testes. The tunica vaginalis is said to have been attacked with cancerous disease, the testis remaining healthy.
