    Abstract:
    A 52-year-old woman presented to our hospital with chief complaints of upper abdominal bloating and lower leg edema. Computed tomography (CT) revealed liver metastasis from a gallbladder tumor. This tumor was diagnosed as neuroendocrine carcinoma (NEC) on performing a biopsy. Physical examination revealed a moon face. Blood tests revealed hypokalemia and high levels of adrenocorticotropic hormone (ACTH) and cortisol. Dexamethasone suppression test revealed that cortisol secretion was not suppressed, and the patient was diagnosed with gallbladder NEC and ectopic ACTH syndrome (EAS). Metyrapone was administered to suppress cortisol production; however, she developed septic shock due to cellulitis in the lower leg and died on the 16th day of admission. A pathological autopsy was performed, which revealed disseminated intravascular coagulation and acute respiratory distress syndrome as the cause of death. Only a few cases of EAS due to NEC originating from the gallbladder have been reported. The patient reported here succumbed shortly after diagnosis, thereby highlighting the challenges in treating gallbladder NEC complicated by EAS.
