Congenital polycythemia or familial erythrocytosis includes a heterogeneous group of disorders with the common characteristic of an absolute increased red cell mass caused by inherited defects in hypoxia sensing. In primary polycythemias there is an innate defect in the hematopoietic progenitors which allows constitutive overproduction whereas in secondary polycythemias normal progenitors are acted on by serum erythropoietin.
