The nodular adrenal.
Nodules commonly occur in the human adrenal gland. They are best regarded as part of the ageing process, produced in response to adrenal vascular changes. Nodules exhibit a wide diversity of size and distribution and are seen not only in subjects with normal adrenal function but also in patients with hypercorticalism (Cushing's and Conn's syndromes). In these disorders, the nodules appear to be a consequence of the diseases, rather than being aetiological.
