Abstract

Tumors that arise from the endocrine pancreas, or the islets of pancreas, are called pancreatic neuroendocrine tumors (NETs). Pancreatic NET have an incidence of ＜0.1 per one million persons, and can lead to secretion of ectopic adrenocorticotropic hormone (ACTH). Herein, we presented a case of patient with Cushing’s syndrome as a result of ACTH-producing pancreatic NET, who underwent successful laparoscopic distal pancreatosplenectomy. A 40-year-old Korean female patient with ophthalmologic discomfort, osteoporosis, and unexplained hypokalemia was admitted to our hospital. Under the suspicion of ACTH producing pancreatic NET after the diagnostic workup, we decided to perform surgical resection. Laparoscopic distal pancreatosplenectomy was performed; and the pathological examination revealed a 1.5 cm-sized grade 2 neuroendocrine tumor of the pancreas, which was encapsulated within the pancreatic parenchyma. After the operation, the patient no longer displayed cushingoid features. ACTH-producing pancreatic NET is rare, but can be one of the causes of Cushing’s syndrome. Surgical resection is a feasible option in treating ACTH-producing pancreatic NET.
