Routine and AMG staining of an AMG-positive adrenal medulla. All adjacent sections are from the same sample (from a 39 year-old male). (a) No histological abnormalities are seen in the adrenal cortex or medulla on hematoxylin and eosin staining. The medullary chromaffin cells have a bluish tinge. The large spaces in the medulla are empty veins. (b) No black grains are present in the adrenal cortex or medulla in a section stained with hematoxylin only. The yellow in the cortex shows erythrocytes. (c) Black AMG staining is seen in the adrenal medulla, but not in the cortex, in a section stained with AMG and hematoxylin.
