• Primary erythrocytosis

   - Polycythemia vera

• Secondary erythrocytosis

   - Congenital:
         - Erythropoietin receptor-mediated
         - High oxygen affinity hemoglobin
         - Bisphosphoglycerate mutase deficiency  
         - VHL (Von Hippel-Lindau) gene mutation (Chuvash erythrocytosis)
         - PHD2 mutations
         - HIF-2 alpha mutations
   - Acquired:
         - Hypoxia driven
             - Central hypoxic process:
                 - Chronic Lung disease
                 - Right-to-left cardiopulmonary vascular shunts
                 - Carbon monoxide poisoning
                 - Smoker's erythrocytosis
                 - Hypoventilation syndromes including sleep apnea (high-altitude habitat)
             - Local renal hypoxia:
                 - Renal Artery Stenosis
                 - End Stage Renal Disease
                 - Hydronephrosis
                 - Renal cysts (polycystic kidney disease)
                 - Postrenal transplant erythrocytosis
             - Pathologic EPO production:
                 - Tumors
                    - Cerebellar hemangioblastoma
                    - Meningioma

                    - Hepatocellular carcinoma
                    - Renal cell cancer
                    - Pheochromocytoma
                    - Uterine leiomyomas
              - Exogenous EPO:
                  - Drug associated 
                    - EPO administration
                    - Androgen administration
