title: [Adrenocortical tumors with neuroendocrine differentiation].
abstract: 18 adrenocortical tumours and 5 pheochromocytomas were studied immunohistochemically. Expression of synaptophysin and chromogranin A was found in cells of cortical adenomas, "frontier" neoplasms and in 20-75% of carcinoma cells, this ultramicroscopically was confirmed by observation of typical neuroendocrine granules. Some groups of cells of cortico-medullary tumours also expressed proteins of neural differentiation (protein S-100).
