An Adrenocortical Carcinoma Evolving from A Small Adrenal Incidentaloma after Years of Latency

ABSTRACT: Objective: Adrenal incidentalomas (AIs) are frequent clinical problems. Although most are benign and nonsecretory, the possibility of malignancy is a concern. We report here a case of adrenocortical carcinoma (ACC) evolving from a small AI, 3 years after initial detection.Methods: We repor...
