Adrenal masses are mostly benign tumors, however the most important question for these tumors is to identify if the tumor is hormone active or not. When an incidental adrenal tumor was found, endocrine (hormone) work-up should be done first.

For hormone active tumors such as pheochromacytoma and Conn’s syndrome, preoperative preparation of the patient is very important. It will be otherwise very harmful to operate the patient without preparation and classified as a malpractice in medical laws. Adrenal gland surgery could be performed with either open or minimally invasive. Conventional open surgery mostly preferred an adrenal mass which appears to be malign and invasive with preoperative imaging modalities. However benign (hormone active or not) adrenal tumors mostly underwent minimally invasive adrenalectomy (Laparoscopic, robotic or Single incision Laparoscopic).
