erythrocytosis

 [ĕ-rith″ro-si-to´sis]
increase in the total red blood 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).
stress erythrocytosis an apparent polycythemia seen in active, anxiety-prone persons, resulting from diminished plasma volume.

e·ryth·ro·cy·to·sis

(ĕ-rith'rō-sī-tō'sis),
Polycythemia, especially that which occurs in response to some known stimulus.

(ĕ-rith'rō-sī-tō'sis)
Polycythemia, especially that which occurs in response to some known stimulus.

erythrocytosis

An increase in the number of red blood cells in a unit volume of blood. This occurs essentially as a response to an inadequate supply of oxygen to the tissues. It occurs at high altitudes, in smokers, in heart or lung disease and in the presence of certain tumours that produce substances that stimulate red cell production. Erythrocytosis also occurs in the condition of primary POLYCYTHAEMIA.

Erythrocytosis

Increased production of red blood cells.

Polycythemia, especially that which occurs in response to some known stimulus.

It is also important to note that erythrocytosis can present with a subarachnoid hemorrhage (nontraumatic by case reports) and dural venous sinus thrombosis (4); therefore, suspicion of erythrocytosis should be confirmed by MRI.

There have been several risk factors implicated for the pathogenesis of thrombosis in patients with CHD such as secondary erythrocytosis, hypoxia/hypoxaemia-induced activation of the pro-coagulant pathways, chronic acidosis, increased fibrin deposition, increased tissue factor expression and impaired fibrinolysis.1 Adults with cyanotic CHD had an increase in red blood cell mass.

According to Dameshek, true polycythemia (polycythemia vera: PV) is a chronic myeloproliferative disorder of the total bone marrow without any evidence of invasiveness, in which erythrocytosis, leukocytosis, and thrombocytosis are all simultaneously present.
On the other hand, many patients with RCC present with or subsequently develop paraneoplastic syndromes including anemia, fever, hypercalcemia, erythrocytosis, thrombocytosis, and AA amyloidosis.
Our patient had raised hemoglobin, splenomegaly, no secondary erythrocytosis, and no elevated erythropoietin (16.5 mIU/ml, normal range 3.7-31.5 mIU/ml).
In T2DM, the life span of red cells can be altered significantly by inflammation, particularly TNF[alpha]-induced oxidative stress [11], obese low-grade systemic inflammatory response syndrome [12], the presence of elevated levels of advanced glycation end-products on the surface of red cells [13,14],hypoxia [15],and excessive erythrocytosis [16].
