[Clinico-morphologic characteristics of 2 tumor forms of primary hyperaldosteronism].

Unilateral adrenalectomy was performed in 32 patients with primary hyperaldosteronism due to tumour of the adrenal gland and with arterial hypertension (AH) of various degree of severity. Stable normalization of AH occurred in 14 patients and in 18 its course improved. The results of a retrospective analysis of a hypotensive effect, the morphological picture of the removed adrenal and the findings of clinico-biochemical and instrumental study made it possible to establish preoperatively the diagnostic criteria for the identification of two tumorous forms of primary hyperaldosteronism: aldosterone-producing adenoma proper and the tumorous form of adrenocortical hyperplasia. They have different pathogenesis and postadrenalectomy hypotensive effect.
