A rare case of polyarthritis panniculitis and pancreatitis.

Extra pancreatic manifestations of pancreatitis are rare, with a prevalence of 2-3%. One such rare manifestation is the triad of joint pain (polyarthritis), tender skin lesions (panniculitis), and pancreatic inflammation (pancreatitis), known as PPP. The pathogenesis of this phenomenon is not fully understood but is believed to involve lipolysis by pancreatic enzymes at lipid-rich skin and joint sites. PPP primarily affects middle-aged males with a history of alcohol use disorder. Diagnosis can be challenging due to the absence of typical abdominal symptoms. Delayed diagnosis may significantly worsen outcomes. Supportive therapy is the mainstay, but resolution requires addressing the underlying pancreatic abnormality. We present a case of a patient with a history of alcohol use disorder and recurrent acute pancreatitis who developed joint pain and skin rash. Extensive work-up ruled out other causes, and imaging and biopsy confirmed the diagnosis of PPP. Symptomatic management and treatment of the underlying pancreatic abnormality led to complete resolution of symptoms. Our case serves to raise awareness of this rare but potentially fatal syndrome.
