摘　　要：BACKGROUND Pancreatic metastases from squamous cell lung carcinoma(SCLC)are unusual.These lesions are often asymptomatic and detected incidentally or during followup investigations,occasionally several years after removal of the primary tumor.CASE SUMMARY A 56-year-old male with SCLC developed jaundice 1 mo after the cancer diagnosis.An abdominal computed tomography(CT)scan showed a mass in the pancreatic head with distention of both intra-and extrahepatic biliary ducts.Endoscopic retrograde cholangiopancreatography and sphincterotomy were performed first,culminating with plastic biliary stent placement.Cytological examination of the pancreatic mass sample collected by fine-needle aspiration(FNA)under endoscopic ultrasound(EUS)guidance revealed the presence of malignant cells compatible with well-differentiated squamous cell carcinoma.After liver function normalized,chemotherapy was initiated with carboplatin and paclitaxel;however,4 d later,the patient presented dysphagia.Cervico-thoracoabdominal CT showed tracheoesophageal fistula and stent migration.After replacement with a 10 cm/10 mm uncovered metallic biliary stent and treatment of the tracheoesophageal fistula with a fully covered esophageal stent,the patient was able to start oral feeding progressively.He died 9 mo after the initial diagnosis.CONCLUSION The diagnosis of pancreatic metastasis from SCLC is challenging for clinicians.EUS-FNA is the primary exam for confirmatory diagnosis.
