Metastasis-Induced Acute Pancreatitis Secondary to Small Cell Lung Carcinoma: A Case Report.

Description Metastasis-induced acute pancreatitis (MIAP) is a condition that occurs when patients develop acute pancreatitis secondary to metastatic malignancy. Most pancreatic cancers are adenocarcinomas that are primary malignancies. On the other hand, metastatic pancreatic lesions are rare, especially from primary pulmonary malignancies. Acute pancreatitis caused by metastatic carcinoma of the pancreas is a very rare presentation. Herein, we present the case of a 63-year-old male with a history of small-cell lung carcinoma presenting to the hospital due to recurrent episodes of acute pancreatitis who was found to have metastatic pancreatic carcinoma. The patient was treated conservatively for his recurrent acute pancreatitis, had a stent placed in the common bile duct to relieve an obstruction and planned for outpatient palliative chemotherapy.
