A rare clinical syndrome of refractory secondary hypertension, renal artery stenosis and erythrocytosis.

Clinical syndrome of refractory secondary hypertension, renal artery stenosis and secondary erythrocytosis could occur in the same patient. We report a rare case of refractory secondary hypertension, renal artery stenosis and primary erythrocytosis as an expression of polycythaemia rubra vera (PV) and suggest that erythrocytosis in a hypertensive renovascular occlusive disease may be primary due to underlying PV. This clinical syndrome should be excluded in such patients with refractory hypertension.
