erythrocytosis
[erith′rōsītō′sis]
Etymology: Gk, erythros + kytos + osis, condition
an abnormal increase in the number of circulating red cells. See also polycythemia.
erythrocytosis (
rith´rōsītō´sis),n (secondary polycythemia) an increased circulating red blood cell mass resulting from compensatory effort to meet reduced oxygen content. May be seen in persons living at high altitudes, as well as in persons with emphysema, pulmonary insufficiency, and heart failure.
erythrocytosis
increase in the total red cell mass secondary to any of a number of nonhematogenic systemic disorders in response to a known stimulus (secondary polycythemia), in contrast to primary polycythemia (polycythemia vera).
erythrocytosis stimulating factor
a lipid isolated from the plasma of anemic animals; distinct from erythropoietin, causes production of microcytes without increasing hemoglobin. Its role in disease is unknown.
stress erythrocytosis
an apparent polycythemia resulting from diminished plasma volume.
