Abstract
Primary small cell carcinoma of the pancreas (SCCP) is a rare malignancy, and has been associated with paraneoplastic features in only 2 reported cases. We report a rare and fatal case of SCCP with likely paraneoplastic features in a previously well 67-year-old woman presenting with abdominal pain. She was found to have abnormal biochemical markers (hyperkalaemia and hyponatraemia) with a normal abdominal CT. Emergency laparotomy identified a mass at the head of the pancreas and liver metastases, she died soon after, and diagnosis was confirmed post-mortem.
