Background. Evidence of solitary pancreatic metastasis from lung cancer is rarely observed at the initial diagnosis. Case. A 38-year-old man visited our hospital with a chief complaint of upper back pain. Magnetic resonance imaging revealed a mass in the left upper lobe with invasion to the third thoracic spine. Computed tomography (CT)-guided needle biopsy of the left lung tumor indicated both a histological and immunohistochemical diagnosis of squamous cell carcinoma. Fluorodeoxy glucose-positron emission tomography (FDG-PET) showed the accumulation of FDG in both tumors observed in the left lung and the pancreas tail. Abdominal dynamic CT revealed a tumor measuring 26×24 mm in size with rim enhancement in the pancreas tail. Endoscopic ultrasound-guided fine needle aspiration (EUS-FNA) of the pancreatic tumor indicated a histopathological diagnosis of metastasis from squamous cell carcinoma of the lung. Conclusion. EUS-FNA is a useful diagnostic procedure to distinguish metastatic pancreatic tumors from primary pancreatic tumors.
