A mass mimicking pancreatic adenocarcinoma, should hepatobiliary surgeons keep it in mind? a case report

Abstract

Isolated metastasis to pancreas from lung cancer is an extremely rare entity, usually reported in case series and case reports in the medical literature; estimated to account for up to 3-5% of all pancreatic lesions. Herein, we describe a case of a male patient suffering from metachronous metastatic lesion to the tail of the pancreas secondary to non small cell lung carcinoma treated 4 years prior to his presentation. The patient underwent pancreatic resection due to high clinical suspicion for the malignant nature of the mass, which was proved to be secondary lesion from its prior primary tumor. To the best of our insight this is one of the few reported cases of such type of pancreatic metastasis that may be misleading for hepatobiliary surgeons during preoperative evaluation.
