Cystic gastric metastasis from pancreatic cancer

Abstract

Gastrointestinal tract metastasis from pancreatic cancer is quite rare. We present the case of a 58-year-old male patient who underwent distal pancreatectomy for pancreatic body cancer 5 years prior. Four years after the initial operation, a 15-mm cystic submucosal tumor was found in the antrum of the stomach. Because the tumor had grown to 25 mm and the level of carcinoembryonic antigen in the cystic fluid derived by ultrasound-guided fine-needle aspiration biopsy was high, partial resection of the stomach was performed 5 years after the distal pancreatectomy. Pathological diagnosis was gastric metastasis of pancreatic cancer. The patient has been alive without recurrence for 13 months after the resection of the cystic tumor. We are not aware of any similar cases of cystic gastric metastasis from pancreatic cancer published in the English literature.
