Ectopic ACTH syndrome (EAS) is a very rare condition, characterized by symptoms of excessive hypercortisolemia. Unregulated adrenocorticotropic hormone (ACTH) secretion of extra-pituitary origin is responsible for approximately 9-18 % of ACTH-dependent Cushing syndrome cases. Tumors presenting as an EAS are located in various organs and differ in both histological type and aggressiveness. In cases of severe EAS diagnostic process should not be prolonged and the main goal is to achieve cortisol secretion control. In this study, patient with EAS of rare, adrenal origin was presented. Adrenal glands should be considered among potential source of EAS.
