A 60 year old man with a two year history of erythrocytosis was found to have a renal cell adenocarcinoma residing in the isthmus of a horseshoe kidney. High levels of serum erythropoietin were demonstrated preoperatively. Resection of the tumor produced a return of the red cell mass to normal, and follow-up surgical exploration nine months later yielded no evidence of recurrent tumor. In this report, the differential diagnosis of primary and secondary erythrocytosis is succinctly discussed, as is the value of newer diagnostic methods (sonograms, CT scans), and the clinical aspects of renal cell carcinoma.
