Anatomical and Histological Studies of Accessory Adrenal Nodules in Caspian Miniature Horses
Microscopic and macroscopic structures of accessory adrenal nodules in Caspian miniature horses (5 males and 5 females) were studied. The accessory adrenal nodules were round or oval and yellow to red. Their maximum diameters varied from 0.1 to 0.5 cm. These nodules were found near the kidneys and adrenal glands, but they were in close contact with the adrenal gland. The accessory adrenal nodules were similar to the adrenal cortex microscopically, and from the outer layer to the inner layer they contained glomerulosa, intermedia, and fasciculata. The adrenal nodules were surrounded by a capsule of collagenous dense connective tissue as well.
