Those at the top come from a patient with adrenal atrophy (with either Addison's disease or long-term patient with adrenal atrophy (with either Addison's disease or long-term corticosteroid therapy). The adrenals at the bottom represent bilateral corticosteroid therapy). The adrenals at the bottom represent bilateral cortical hyperplasia. This could be due to a pituitary adenoma secreting cortical hyperplasia.
