Description
		
The origin of the tumour from the pelvic wall is well seen; the tumour is some 3.0 cm in maximum 
dimensions and has a characteristic papillary pattern. It is partly covered by blood clot and does not 
appear to be extending beyond the wall of the pelvis. 
		 History
		
 This man had a transitional cell carcinoma of the bladder in 1979 which subsequently 
required regular diathermy; he was admitted on this occasion for assessment of further haematuria. 
A pyelogram showed a non-functioning kidney on the right side and a retrograde pyelogram and CT 
scan confirmed the presence of a tumour in the renal pelvis.
