Publication date: Available online 27 November 2014 Source:Kidney Research and Clinical Practice Author(s): Dong Hyun Lee , Ji Hye Min , Sang Byung Bae , Hyo Wook Gil , Jong Oh Yang , Eun Young Lee , Sae Yong Hong A 78-year-old man on hemodialysis presented to our hospital with erythrocytosis. He had started hemodialysis 4 years previously, with a hemoglobin level of 9.8g/dL, and was administered erythropoiesis stimulating agents and ferrous sulfate. Two years previously, his hemoglobin level increased to 14.5g/dL and the treatment for anemia was discontinued. He continued hemodialysis thrice weekly; however, the hemoglobin level had increased to 17.0g/dL at the time of presenting to our hospital. His serum erythropoietin level was 31.4mIU/mL (range, 3.7–31.5mIU/mL), carboxyhemoglobin level was 0.6% (range, 0–1.5%), and oxygen saturation in ambient air was 95.4%. The JAK2 V617F mutation was not observed and other bone marrow abnormalities were not identified. The patient was diagnosed with bladder cancer and a transurethral resection was performed. Eight months after the treatment of bladder cancer, his hemoglobin level was 15.1g/dL, and he was diagnosed with idiopathic erythrocytosis.
