Abstrakt: The authors report the results of an ultrastructural study of a beta-cell insuloma with amyloid stroma. In this stroma they found fibroblast-like cells never previously seen in tumor of this type. The cytoplasm of these cells was filled with microfilaments, giving them the appearance of amyloid. These cells seem to be similar to the so-called 'stromal cells' described in medullary carcinoma of the thyroid gland. The role of stromal and epithelial cells in the production of amyloid in endocrine tumors is discussed. [ABSTRACT FROM AUTHOR]
