Acinar cell carcinoma is a malignant epithelial neoplasm composed of cells with morphological resemblance to acinar cells and with evidence of pancreatic exocrine enzyme production. Cases with significant endocrine or ductal components (i.e. > 25% of the neoplasm) are regarded as mixed carcinomas (mixed acinar-neuroendocrine carcinoma, mixed acinar-ductal carcinoma, or mixed acinarneuroendocrine- ductal carcinoma)1

, but most cases occur in late adulthood. Immunohistochemical detection of the production of pancreatic exocrine enzymes (e.g. trypsin, chymotrypsin, lipase, and elastase) is helpful in confirming the diagnosis. Acinar cell carcinomas are aggressive; however, outcome is better than that for stage-matched infiltrating ductal adenocarcinomas, with 5-year survival figures of 25?50% depending on stage at diagnosis 14
