BACKGROUND: Erythrocytosis, a rare paraneoplastic syndrome, generally occurs in
patients with clear cell renal cell carcinoma and has never been reported in
patients with chromophobe renal cell carcinoma. CASE PRESENTATION: We report a
case of a young man suffering from a giant (22-cm) mass on his left kidney.
Because of a history of polycythemia vera, the patient had been treated for the
condition for 9 years. Radical nephrectomy was successfully performed, and the
postoperative pathologic examination confirmed a diagnosis of chromophobe renal
cell carcinoma. Unexpectedly, the symptom of erythrocytosis disappeared after the
surgery. Further examination and analysis were performed, and we finally
attributed his erythrocytosis to chromophobe renal cell carcinoma. CONCLUSIONS:
Chromophobe renal cell carcinoma could cause erythrocytosis, but the clear-cut
mechanism needs further research. Secondary erythrocytosis such as those related
with renal tumors should be taken into consideration during the diagnosis of
polycythemia vera.
