The morphological and immunohistochemical characteristics of the adrenal gland of the lion(Panthera leo) have been studied. In the light microscopic level, the adrenal gland was surrounded by thick capsules arid weak development of the zona glomerulosa was detected. Some medullary tissues were directly connected with capsules, however the adrenal gland in the lion 'demonstrated somewhat pseudolobulated appearance. Weakly or strongly stained chromogranin-immunoreactive cells were detected in medullary regions of the adrenal gland of the lion by immunohistochemistry, and weakly stained chromogranin-immunoreactive cells were detected more frequent than strongly stained ones.
