    This study compares two primary aldosteronism cases. Findings suggest an external factor may trigger bilateral adrenal hyperplasia, unlike solitary adenomas.

    Area of Science:

    • Endocrinology
    • Nephrology
    • Internal Medicine

    Background:

    • Primary aldosteronism presents with electrolyte and hormone imbalances.
    • Distinguishing between adrenal adenoma and hyperplasia is crucial for treatment.

    Observation:

    • Two patients with primary aldosteronism were studied: one with a solitary adrenal adenoma, another with bilateral nodular hyperplasia.
    • Biochemical analysis revealed distinct differences in excised adrenal tissue between the two patients.

    Findings:

    • Plasma from the patient with bilateral adrenal hyperplasia stimulated aldosterone secretion in a transplanted sheep adrenal gland.
    • Plasma from the patient with a solitary adrenal adenoma did not elicit an aldosterone response.

    Implications:

    • These results support the hypothesis of an extra-adrenal stimulus in the development of bilateral adrenal hyperplasia.
    • Further research into external factors influencing adrenal function is warranted.
