Abstract

<p>Few cases have been reported about surgery for pancreatic metastases, and cases from osteosarcoma are extremely rare. We report a case of pancreatectomy for metachronous pancreatic metastasis post-surgery for osteosarcoma. Surgery was performed on a 55-year-old man for osteosarcoma of the mandible 26 years ago. He received pulmonary resection, radiofrequency ablation, chemotherapy and radiation therapy for pulmonary metastases 2 years and 17 years after resection of primary tumor respectively. He was referred to our hospital with a pancreatic tumor from routine screening 7 years later. The mass measuring 53mm in size with blood flow in the tail of the pancreas was identified by CT. Endoscopic ultrasound (EUS) revealed the irregular mass with both low and iso echoic components, and the biopsy was compatible for metastatic osteosarcoma. PET-CT indicated an abnormal uptake value in the pancreatic tumor, but no evidence of other distant metastasis. He was diagnosed with metachronous pancreatic metastasis from osteosarcoma and distal pancreatectomy was performed. The post-operative course was good and he was discharged 10 days post-surgery with no complication. The pancreatic metastasis from osteosarcoma is extremely rare and this case is worth reporting because it is a rare pathology with recurrence after long-term follow-up.</p>
