[Acute pancreatitis and obstructive jaundice secondary to metastases from lung cancer]

Lung cancer is one of the most frequent neoplasms. The symptoms are due to the cancer itself, its extension, and associated paraneoplastic syndromes. Although biliopancreatic metastases are common, biliopancreatic involvement as the initial symptom of lung cancer--whether as pancreatitis or obstructive jaundice--is rare. We describe our clinical experience, reporting two patients with acute pancreatitis and one patient with obstructive jaundice as the clinical presentation of advanced lung cancer. We also provide a brief review that highlights the absence of guidelines in this situation.
