Pancreatitis, panniculitis, and polyarthritis syndrome complicated with systemic intraosseous fat necrosis

Pancreatitis, panniculitis and polyarthritis syndrome (PPP syndrome) is a clinical syndrome with cutaneous panniculitis and polyarthritis on the basis of pancreatic diseases, which is quite rare. The occurrence of arthrosis and skin lesions is not completely synchronous with pancreatic diseases, so it is often missed or misdiagnosed due to the lack of obvious abdominal signs, with severe sequelae and high mortality. In this article, we report a case of PPP syndrome with severe rare osseous complications caused by chronic pancreatitis.
