[Electron microscopic and morphometric study of the cellular composition of several forms of goiter in man].

According to the ultrastructural patterns four varieties of follicular cells are recognized in the cell population of the human goiter. The parenchyma of different goiters is composed of the same cell types and varieties. Goiters differ in percentages of these cells. The ultrastructure of the main cell form is correlated with the functional activity of the goiter. The "map" of cell composition of some forms of goiter is given, which may be used for a more exact diagnosis of the goiter, especially in the cases of discrepancy between the light microscopical morphological data and clinical picture of the desease.
