In many joints and tendon sheaths, particularly the latter, we find certain detached, usually colorless, firmly resistant masses, of smooth and polished surface, lying in a collection of fluid, in size from a minute particle up to that of a melon-seed. These have been known at various times as _rice grains_, _melon-seed bodies_, _corpora oryzoidea_, etc., and for a long time their explanation was a mystery. It is now well established that in the majority of instances these are the result of fungous granulations which have become detached in small pieces, which then, in the absence of infection, have shrunken and become rounded and polished by attrition. The bursal enlargement and distention with fluid in which they are usually found is commonly spoken of as _hygroma_ of that particular bursa. Tuberculosis of these bursæ, however, does not always result so harmlessly as the formation of these bodies, but, on the contrary, tuberculous infiltration may extend beyond the serous limits to the surrounding soft parts, with a tendency finally to external escape, just as in the case of bone lesions. These constitute affections of the soft parts which are more or less destructive, and are difficult, often impossible, to deal with, because of the mutilation which a thorough extirpation of the disease would necessitate. _In the testicles and ovaries_, particularly in the former, tuberculous disease is frequently met with. In the testicles it begins usually in the _epididymis_, forming a somewhat dense nodule and a distinct tumor, easily observed from the outside, although its minute character may be still concealed. The tendency here is almost invariably to progressive infiltration and breaking down, either into a caseous mass or, more commonly, into puruloid material, while sometimes acute infection supervenes. It is not always easy to distinguish between syphilis and tuberculosis of the testicle, though the latter is usually characterized by the same tendency to effusion into the adjoining serous cavity, _i. e._, that of the tunica vaginalis, as is manifested in disease of the lungs or bones. When the disease is extensive the overlying skin is involved, and frequently the surgeon is called to deal with cases of perforation and escape of fungoid tissue on the outside. _In the kidneys, in the ureters, as also in the bladder_, tuberculous lesions are noted, the miliary form being particularly frequent in the former. Tuberculous disease of the kidney leads sooner or later to caseation and a condition of pyonephrosis or its equivalent, which calls practically always for extirpation of the affected organ. Tubercle bacilli are sometimes recognized in the urine, but only when the lesion has an opportunity of discharging into one of the urinary passages.
