A CASE OF SQUAMOUS SELL CARCINOMA OF THE RENAL PELVIS ASSOCIATED WITH STAGHORN CALCULUS AND PYONEPHROSIS

Abstract

A 77-year-old man who had undergone right simple nephrectomy in 1976 was admitted to our hospital with complaint of fever and left flank pain. X ray film showed a staghorn calculus. CT and MRI revealed a heterogeneous mass on upper pole of the left kidney. Angiography demonstrated proliferation of abnormal vessels. He was diagnosed as having a left renal tumor and underwent left radical nephrectomy with resection of pancreatic body and splenic flexure of the colon, and of the spleen because of adhesions. Pathologically, well-differentiated squamous cell carcinoma had invaded to pen-renal adipose tissue, but did not the pancreas, colon and spleen. He underwent hemodialysis via a femoral catheter and died of MRSA infection 42 days after the operation.
