Pancreatic neuroendocrine tumors (p-NETs) entail a vast array of tumors, which can vary from benign neoplastic growths to rapidly aggressive malignancies. Such is the case with ectopic adrenocorticotropic hormone (ACTH)-producing p-NETs. These tumors have been found to be quite aggressive and a challenge to treat, especially due to the occurrence of metastatic disease even after resection of the primary tumor. We discuss the case of a 44-year-old female who initially presented with vague, non-specific symptoms, in which a malignant p-NET was found to be the cause of her clinical presentation. Although resection of the pancreatic mass was performed, the patient presented again with metastatic disease to the liver.
