A Case of Pancreatitis–Panniculitis–Polyarthritis Syndrome due to Primary Hepatic Neuroendocrine Tumor

A 66-year-old male patient presented to our department with subcutaneous nodules in both lower extremities accompanied by pain. Skin pathology suggested pancreatic panniculitis. Subsequent imaging and histopathology identified a rare case of pancreatitis-panniculitis-polyarthritis syndrome secondary to a primary hepatic neuroendocrine tumor. This case highlights the rare association between nonpancreatic conditions and pancreatic panniculitis.
