Background In primary aldosteronism (PA) the main source of aldosterone hypersecretion is an aldosteroneproducing adenoma (APA) or a bilateral hyperplasia. Histopathology of the adrenal gland from patients with PA has been difficult, as there are no morphological criteria to ascertain which are the cells that produce aldosterone. We therefore applied new specific antibodies to explore which cells in the adrenal contain the enzymes for aldosterone and cortisol production, respectively. Methods Adrenals from 24 patients with PA were studied. After routine preparation, consecutive sections were stained with antibodies for CYP11B1 (cortisol) and CYP11B2 (aldosterone) enzymes. Results APA had a strong immunoreactivity for CYB11B2. In adrenals from seven patients, we found no APA, but several nodules with strong CYB11B2 immunoreactivity, indicating aldosterone-producing nodular hyperplasia. Conclusions Immunohistochemistry of adrenal steroidogenic enzymes provides novel diagnostic information. This may become an important part of routine histopathology, and contribute to improved clinical management in PA.
