[Solid-cystic acinar cell tumour of the pancreas (author's transl)].

A solid-cystic acinar cell tumour of the pancreas was found in four female patients. This particular form of benign pancreatic tumour is characteristically found in young women, often reaches a large size (2.5-10 cm), presents as a spherical mass in computed tomography or ultrasonography and does not show infiltrative growth or metastases. Tumours can be readily enucleated or resected. This type of tumour does not yet appear in the WHO classification of epithelial pancreatic tumours. It probably arises from the acinar cells. Accurate differentiation from previously known highly malignant acinar tumours is absolutely necessary on account of the good prognosis of this type of tumour.
