=Cystic Disease of the Testis.= The cysts may be but few, or very numerous. The testis is proportionately enlarged, indurated, of a yellowish-white and opaque appearance, and studded with cysts varying in size. The contents are, in the younger cysts, a clear, amber-colored fluid; in the older ones, more thick, viscid, highly albuminous, and of a brownish color. The cysts are sometimes imbedded in solid stroma, probably of fibroid tissue; sometimes small masses of enchondroma are found between them. When of an innocent character, the cystic disease is characterized by the presence of tessellated epithelium in the cysts; when malignant, by the presence of nucleated cancer cells. “Occasionally cystic tumors of the testicle are met with, in which the substance of the organ is atrophied or absorbed, and its place occupied by one or more large thin-walled sacculi containing fluids of different color and consistence, dark or fatty.” =Tubercles= are not very unfrequent, and appear sometimes in the body of the gland, but oftener in the epididymis, whence they may spread to the testis. They occur as gray granulations, infiltrated or encysted, and varying in size from a pin’s head to a plum-stone. They are commonly found in all stages of development and disintegration in the same organ. Their presence in and between the tubuli produces inflammation, suppuration and disorganization of the structure of the testis, with which they become mixed, so as to form a cheesy mass of a dirty buff color. This may, by ulceration, perforate the scrotum, and protrude as a fungous growth of a pale, reddish-yellow granular mass. This disease of the testis is frequently found in connection with pulmonary tubercle, or general tuberculosis. _Tubercular syphilitic sarcocele_, described by Hamilton, of Dublin, is a variety occurring in an advanced stage of constitutional syphilis. “_Cretaceous matter_ is occasionally met with in the testis, doubtless the residue of tuberculous deposit which has softened and undergone calcareous change.” =Tumors.= _Fibroid tumors_ of small size are sometimes found developed within the visceral layer of the tunica vaginalis, or within the substance of the cord. _Fatty tumors_ may be found, which have originated within the tunica albuginea, the dartos, or within the fibrous connective tissue of the cord. _Cartilaginous tumors_ of small size, originate with the substance of the gland, and are frequently associated with cystic disease or cancer.
