[Preoperative diagnosis of thyroid cancer by karyometry of thyrocytes]

Karyometry revealed that the distribution of thyrocyte nuclei by the size of their area on histograms depends on the type of thyroid disease. If the ratio of the share of thyrocyte nuclei area in the second and third ranges on distribution histograms is more than 1, thyroid cancer is diagnosed, if it less than 1, it may mean follicular adenoma, autoimmune thyroiditis, nodular colloid or diffuse toxic goiter.
