Appropriate causes of increased erythropoietin include lung disease, cyanotic heart disease, living at high altitudes, or abnormal hemoglobins with increased oxygen affinity. Inappropriate causes of increased erythropoietin include erythropoietin-secreting tumors, such as renal cell carcinomas, hepatomas, or cerebellar hemangioblastomas.
