title: [A study of pancreatic insulinomas by electron microscopy. 9 cases (author's transl)].
abstract: Nine hypoglycaemia-inducing pancreatic tumours were studied by electron microscopy. In 8 of these tumours, it was possible to identify, within the cell cytoplasm, secretory granules with a "paracrystalline" content, identical in appearance to the granules of the B cell of the normal human pancreas. Thus electron microscopy would appear to be a reliable and sensitive method for the morphological identification of these endocrine tumours of the pancreas.
