ected independently of the tumor massfor a distance of 3 cm. The new growth had enlarged ventrally and laterally. Complete encapsulationwas evident. The surface was roughly nodulated. This was caused in part bythe projecting poles of the kidney and in part by irregular bulging incident tothe enclosed new growth and hemorrhagic changes, for on cross section just beneaththe capsule there were seen areas of hemorrhage and areas of vigorous new growth,causing definite thinning out of the capsule. On section ventrally from pole to pole at a distance of 1 cm. from the mid-point of the pelvic margin of the kidney, the capsule of the new growth was foundat the center on the medial side to be 1 cm. and in the poles 3-4 cm. thick. (Fig.1.) The margin of the new growth was sharply defined but in the upper pole therewas a separate papillary projection at a distance of 5 mm. external to the marginof the tumor. This occupied the position of an obliterated calyx. Multiple vertical 226 JAMES E. DAVIS

NEOPLASIA OF THE KIDNEY 227 sectioning revealed a varying thickness of capsule down to 1 mm. upon the lateralsurface. The central portion throughout exhibited numerous recent and old hemorrhages.A tracery of fine light-colored seams could be followed throughout the growth. Theolder portions of the growth were centripetal and the new portions centrifugal. The entire new growth portion was of light color except where changed byhemorrhage and necrosis. When torn apart the surfaces presented a minute polypo-arboreal appearance. The fatty capsule was thick and its fat lobules firm andresistant. Histopathology: The sections taken from parts of the kidney not involved inthe new growth change showed compacted tissue with consequently deformed tubularand glomerular units. The poles of the kidney which had the greatest de,pth ofimi
