Histologic findings vary according to the type of primary aldosteronism that a patient has. Typical aldosteronomas are characterized by adenomatous tissue, usually with zona fasciculata–type morphology. Most of these tumors are small (< 3 cm in diameter), and most of the cells are lipid-laden cells arranged in acini or cords. Associated focal and/or diffuse hyperplasia often occurs.
