A tubular form of carcinoma in which solid strandsof epithelial cells are seen growing into the lumina of the tubules andby their union forming irregular open spaces. There is no infiltrationof the stroma. Microscopically the types of carcinoma vary in the prostate as theydo in other organs. The most common type is a mixed adenocarcinoma and carcinomasimplex, this being the form present in 11 of the 18 cases in which An Operation for Cancer of Prostate. 531 microscopic examinations were made. Four of these showed someareas of pure adenocarcinoma while other areas presented the scirrhustype. These might be termed a scirrhus variety of adenocarcinoma.Pig. 12 (Case 13) is an area of scirrhus from one of these cases. In seven cases the adeno type varied with portions in which theepithelium formed islands of cells separated from each other, some-times by slender and sometimes by broad bands of stroma. Often,

Nests of cancer cells lying in between dense bundles however, the carcinoma is seen breaking through these limiting bandsof stroma and infiltrating lawlessly so that the alveolar arrangementmay be entirely lost. In three cases the neoplasm was a carcinoma simplex; two of themedullary and one of the scirrhus type. Fig. 13 from Case 64 represents the very cellular character ofone of these medullary tumors, and the insignificant amount of stromapresent. A large portion of the tumor was of this character.
