Purpose Acinar cell carcinomas (ACC) and adenomas (ACA) of the pancreas are rare entities. Sufficient knowledge about occurrence and prognosis is scarce. Methods A retrospective chart review of our database was performed for all patients who had undergone pancreatic surgery between 2006 and 2018. Results were compared to recent literature findings. Results Nine patients were diagnosed with ACC and four patients with ACA of the pancreas in the study period. ACC patients were older and more often male than patients of the ACA group. ACC were mainly localized in the pancreatic head, whereas ACA were more often found in the distal pancreas. Tumor markers are not necessarily elevated, even in case of malignancy. Conclusions ACC and ACA are very rare pancreatic tumors. Both entities account for less than 1% of all pancreatic neoplasms. Diagnosis is challenging due to unspecific radiologic features and clinical symptoms. Nevertheless, a patient complaining of abdominal discomfort and an unclear hypodense pancreatic lesion should undergo surgical exploration.
