title: Endoscopic sonography and sonographically guided fine-needle aspiration biopsy in the diagnosis of unusual pancreatic metastases from synovial sarcoma.
abstract: Pancreatic metastases are commonly solitary solid lesions frequently derived from primary renal cell carcinoma, lung cancer, or melanoma. Very few case reports have described cystic-appearing metastases in the pancreas and even fewer have reported a combination of cystic and solid metastatic lesions. Synovial sarcoma is a rare and aggressive soft tissue neoplasm, frequently metastasizing to the lungs and bones. We present a case of primary synovial sarcoma with multiple solid and cystic-appearing pancreatic metastases diagnosed by endoscopic ultrasound and sonographically guided fine-needle aspiration.
