CARCINOMA OF RENAL PELVIS
A man of 66 with a history of back pain and haematuria was found on radiological examination to have a non-functioning right kidney and two opacities in the right lung. A palliative nephrectomy was performed because of presistent haematuria.
The specimen is a kidney mounted to display the cut surface. Projecting into the markedly dilated pelvis and calyces is a solid pale tumour apparently arising from the pelvic epithelium. The tumour has an irregular lobulated surface, and has infiltrated the upper pole of the kidney. There is compression atrophy of renal tissue, due to hydronephrosis. Histological examination revealed infiltrating poorly differentiated transitional cell carcinoma of the renal pelvis (grade III).
