title: Metachronous pancreatic acinar cell carcinoma discovered in early stage during follow-up of breast cancer: report of a case.
abstract: We present an extremely rare case of early-stage acinar cell carcinoma of the pancreas. A 49-year-old woman, who had undergone radical surgery for breast cancer 3 years earlier, was suspected to have a rib metastasis during follow-up. She also had a family history of cancer. No accumulation was seen in the left rib on (18)F-fluorodeoxyglucose positron emission tomography with computed tomography, but incidental high uptake into the pancreatic head suggested malignant pancreatic tumor. The tumor was completely resected by pancreatoduodenectomy, and pancreatic acinar cell carcinoma was demonstrated histopathologically. To the best of our knowledge, this is the first reported case of a pancreatic acinar cell carcinoma smaller than 1 cm to be detected by (18)F-fluorodeoxyglucose positron emission tomography and computed tomography.
