An American text-book of genito-urinary diseases, syphilis and diseases of the skin . reful study of later cases has shown that theyhave no relation to the prostate, and that they are, in fact, true adenomatawhose type is the submucous glands. The canals may be so dilated as to 382 DISEASES OF THE BLADDER. form small cysts in the substance of the growth. Although rare, suchtumors, on account of their site, are clinically important. Albarrans case presented symptoms which suggested vesical tuberculosis. The true adenoma is entirely exogenous : any infiltration would indicate acarcinomatous process. Carcinomata.—The carcinomata of the bladder vary greatly in are exogenous formations which have a marked resemblance either topapillomata or adenomata; they are, however, also always endogenous. Othersare purely endogenous, and the mucous membrane may not be affected at all. Primary cancer of the bladder is not only very rare, but is quite rare incomparison with secondary vesical cancer. Out of 40 cases of vesical cancer reported in over 7000 necropsies col-. FiG. 113—Adenoma of the bladder (Clado). lected by Hasenclever, only 3 were primary, and only 14 cases were foundin the records of the Pathological Institute in Munich (Zansch). Males aremore frequently affected than females, in the proportion of nearly 3 to 1 :of 137 cases collected by Clado, 99 were in males. The age affected isusually between forty and fifty-five, although malignant disease has beenseen in the infantile bladder. It has been customary to divide the malignant epithelial growths of thebladder into epitheliomata and carcinomata, with the further addition by someauthors of adeno-carcinomata. We do not believe such divisions to be patho-logically necessary or clinically advantageous. All such growths are, in thestrict pathological sense, carcinomata. As above stated, however, they differwidely in gross and microscopic appearances, so that for purposes of descrip-tion it is convenient
