[Solitary metastasis to the pancreas in a patient with lung cancer]

Pancreatic metastasis from squamous cell lung cancer: computed tomography and magnetic resonance imaging findings

Metastatic lesions of the pancreas are uncommon. The incidence of pancreatic involvement with squamous cell carcinoma is the lowest among the different histological subtypes of lung cancer. We present the clinical data, pathological findings, and imaging features of two cases of pancreatic metastasis from squamous cell lung cancer with a literature review. A 75-year-old man and a 67-year-old man were both diagnosed with metastatic pancreatic tumors from squamous cell lung cancer during a multidisciplinary team discussion. Both patients were misdiagnosed as having a neuroendocrine tumor of the pancreas by imaging examination before surgery. Squamous cell lung cancer metastasis to the pancreas is extremely rare, and the atypical clinical and radiological presentations make it difficult to distinguish metastatic tumors from primary pancreatic tumors.

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

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.

Metastatic squamous cell carcinoma to the pancreas: Report of an extremely rare case

Secondary pancreatic lesions are very uncommon. Resection of these metastatic lesions with a curative intent has been reported in selected patients; however, the survival benefit from these procedures has yet to be clearly determined. A 78-year-old male patient presented to our department with obstructive jaundice. Three years prior to presentation the patient had undergone right pneumonectomy, due to stage IIA, low-grade squamous cell lung carcinoma. After resection, the patient received adjuvant chemotherapy, with no evidence of local or systemic recurrence over the following 3 years. Abdominal computer tomography on admission revealed a 3-cm lesion located at the head of the pancreas, causing biliary obstruction. Endoscopic ultrasound biopsy revealed malignant cells, suspicious for squamous cell carcinoma. Due to the limited extent of the metastatic disease and in view of the patient's good condition, surgical resection was proposed and the patient successfully underwent pancreaticoduodenectomy. Histological examination of the resected specimen confirmed a squamous cell carcinoma, with an immunochemical profile similar to that of the primary lung tumor. Therefore, pancreatic resection with curative intent may be feasible in selected patients with secondary metastatic tumors. However, further studies are required in order to determine the benefit of these major procedures in terms of survival outcomes.

An Unusual Case of Pancreatic Metastasis from Squamous Cell Carcinoma of the Lung Diagnosed by EUS-Guided Fine Needle Biopsy

We report a case of a 70-year-old man who presented with abdominal pain and weight loss, with initial imaging showing simultaneous mass lesions in the pancreas and lungs along with extensive lymphadenopathy in the thorax up to the left supraclavicular region. Core biopsies of the left supraclavicular lymph node showed squamous cell carcinoma, which required differentiation between secondary and primary pancreatic neoplasms. Endoscopic ultrasound-guided sampling using a novel fine needle biopsy system was key to making a definite histological diagnosis and determining the best treatment plan.
