centre of the nodules was marked. The epithelial masses in the peripliery partly infiltrated, 
partly compressed the surrounding liver substance. The kidneys, in addition to a slight patchy 
sclerosis of the cortex, presented a most unusual appearance. Throughout the cortex the 
glomeruli were striking objects, as is well seen in the figure. The prominence of the glomeruli 
was due to deeply-stained epithelium lining the parietal layer of Bowman's capsule. A further 
examination showed the epithelial lining to consist of several layers of slender columnar cells with 
oval nuclei. A marked feature in the majority of the glomeruli was the normal appearance of the 
vascular tuft and its epithelial covering. In a few instances the proliferating epithelium com- 
pletely filled the capsule. In places the growth penetrated the basement membrane and infiltrated 
the surrounding tissue, and in not a few cases the epithelium of the renal tubules in immediate 
relationship to the glomeruli was replaced by that of the growth. The small nodules of white 
growth were found to consist of masses of cells with a considerable amount of stroma, in which 
some bundles of fibres resembling muscle-fibres were present. 
The general appearance of the glomeruli is well seen. The dark layer consists of 
several layers of slender columnar cells ; a similar deeply-stained epithelium is 
present in the tubules adjoining some of the glomeruli. The normal appearance 
of the epithelial covering of the vascular tuft is obvious. 
The occurrence of a malignant epithelial tumour at the age of i6 years is very unusual, 
and the condition of the kidney is almost unique. I have been able to find only two cases on 
record which in any way resemble my own. 
Remarks 
O. HiLDEBRAND* reports a case of small cell carcinoma in a child jet. 5. The referat 
says HiLDEBRAND Considered the tumour to arise in the glomeruli, and that the proliferating 
epithelium therein finally infiltrated the surrounding tissue.
