ABSTRACT
Adrenal tumors have clinical significance as both hormone-secreting neoplasms and malignant tumors. In addition, adrenal masses are commonly encountered as an incidental finding on abdominal imaging studies. It is essential for oncologists to be comfortable with the recognition of syndromes of adrenal hormone excess, the appropriate treatment of malignant adrenal neoplasms, and the management of incidentally discovered adrenal masses. The adrenal gland is unique in that within a single organ are combined two different histological types with distinct associated clinical entities. In this chapter the discussion of cortical neoplasms will be separated from that of medullary tumors.
