Adrenocortical Carcinoma: Complete Surgical Resection After 18 Years.

Adrenal cortical carcinoma (ACC) is a rare neoplasm often associated with an aggressive biological behavior. Complete surgical resection is the mainstay of therapy for ACC and offers the best chance for prolonged disease-free survival. We present an unusual case of a long-standing adrenal mass, well documented over a period of at least 18 years, without the development of metastatic disease, and ultimately proven to represent ACC after successful surgical resection. Physicians should be aware that ACC can present with a wide spectrum of biological behavior, from very aggressive to more indolent disease.
