An Operation for Cancer of Prostate. 515 The section is white with small grayish dots and lines. It is distinctlyfibrous in feel. The urethra is intact, although surrounded closely bythe tumor which has invaded the entire prostate. A fairly thick intactcapsule surrounds the prostate everywhere except at its upper end, wherethe growth has spread upward around the lower ends of the vasa defer-entia and seminal vesicles and invaded the posterior surface of theanterior part of the trigone. A cross section through the tip of the semi-nal vesicles and the trigone presents the following picture. Above, thedarkly stained mucosa of the trigone apparently intact, immediately be-neath this a mass of carcinoma, 2 cm. wide, adherent to and involving.

Sections of the upper portion of bothseminal vesicles examined microscopically are found free from disease,but the vas deferens is involved fairly high up on each side, the lumenbeing completely filled with cancer cells. The bladder wall, near theupper line of excision, is apparently free from invasion, but in the fatbeneath it and to the outer side of the seminal vesicle small masses ofcancer cells are seen. The capsule covering the prostate and seminalvesicles is invaded on the inner side in places. The structure of theneoplasm is adenocarcinoma; in places carcinoma solidum. Microscopic examination.—The predominating type is that of an adeno-carcinoma although occasional areas of scirrhus are encountered. There 516 Hugh H.
