Many of the bizarre symptoms, laboratory findings, and metastatic behavior of hypernephroma are well known.1,2 This report is stimulated by our experience with a patient having a hypernephroma which metastasized to the glomeruli of the opposite kidney and caused renal failure. A review of recent literature did not reveal a previous description of this unusual metastatic spread.
Report of Case
A 48-year-old Caucasian man (No. 05-30-73) was referred to this hospital for consideration of extracorporeal hemodialysis.Six weeks before admission he developed a midlumbar backache.
