Adrenal adenomas can be divided into medullary adenomas and cortical adenomas, depending on the site of occurrence. Cortical adenomas are smaller in size and generally less severe, while medullary adenomas, such as pheochromocytomas, are larger in size and cause a significant increase in blood pressure in patients and are more severe. Adrenal adenomas can be divided into benign and malignant tumors according to the nature of the tumor. Generally, benign tumors are less severe, while malignant tumors grow faster and larger, easily metastasize, invade adjacent organs and are more severe.
