A CASE OF RENAL CELL CARCINOMA WITH HYPERGLYCEMIA

Abstract

A 71-year-old male with hyperglycemia was incidentally found to have a right renal tumor. Hyperglycemia had been controlled by administration of 34 units of insulin. Immediately after radical nephrectomy, hyperglycemia was improved to be able to stop insulin. His fasting blood glucose level remained within normal limits without any treatment. Laboratory studies, however, failed to reveal any endocrinopathy derived from renal cell carcinoma responsible for the diabetic state.
