Cushing's Syndrome Caused by an ACTH-Producing Neuroendocrine Carcinoma of the Gallbladder / 대한내과학회지

ABSTRACT

Neuroendocrine tumors of the gallbladder are rare, and typically found incidentally after a cholecystectomy. Few data are available on adrenocorticotrophic hormone (ACTH)-producing neuroendocrine tumors originating specifically from the gallbladder. We experienced the case of a patient with a gallbladder mass who presented with Cushing's syndrome, who was subsequently diagnosed as an ACTH-producing neuroendocrine carcinoma of the gallbladder. Despite being rare, hormone-producing neuroendocrine tumors should be part of the differential diagnosis in patients with Cushing's syndrome.
