TUMORS OF THE BLADDER. 383 The first form is one which is closely allied in many respects to theadenoma—the adeno-carcinoma or cylindrical epithelioma. This is a raretumor. Like the adenoma, it was originally classed by Klebs as of prostaticorigin, but this has been disproved by its occurrence in the female bladder(Kaltenbach), and by the histological demonstration that it springs from thedeep glands of the mucous membrane and has no connections with the pros-tate, which has, furthermore, in several cases, been shown to have been normal. It is most often a pediculated growth, but may be inserted with a broadbase. The surface is tabulated and covered with fine villi; the generalaspect is often quite like the papilloma. It is not often found Fig. 114.—A, epitheliomatous turao vart-like growths ; C, villous growths around a vesical cell(Clado). When the site of implantation is examined, it is noted to be induratedand infiltrated; the mucous membrane is bound down and does not movewhen traction is made upon the pedicle. Upon section small cysts filledwith a thick material may be exposed. In the recorded cases the growthshave been most often on the base; the size has been that of a nut to an egg. The stroma consists usually of fully-formed connective tissue, mixed witha few elastic and muscular fibers. In several cases, however, the connectivetissue has been of the cellular embryonal type, which thus presented a sarcom-atous appearance. The muscular tissue has been in several cases in greatexcess: Virchow indeed described under the name of myo-carcinoma a car-cinomatous tumor whose stroma was entirely made up of muscular epithe
