Abstract:
Ectopic production of adrenocorticotropic hormone (ACTH) by gastrointestinal neuroendocrine tumours (NETs) is relatively uncommon. We report a rare case of a liver metastatic G1 low-grade NET of the intestine that induced hypercortisolism after surgical resection. A 50-year-old man was admitted for an intestinal obstruction caused by a tumour of the intestine. Paraneoplastic Cushing syndrome was diagnosed more than a year later following the appearance of cushingoid symptoms, despite stable disease according to RECIST criteria but chromogranin A increase. Ketoconazole and sandostatin medical treatment and liver chemoembolization never managed to control the hypercortisolism unlike the bilateral adrenalectomy. The identification and effective management of this uncommon statement of ectopic ACTH secretion is important to improve the patient's prognosis and quality of life.
