[A morphometric study of the lymphoid cell population in biopsy material from patients with different thyroid pathologies]

Using cytometry of lymphocytes, prolymphocytes and lymphoblasts in touch smears of biopsy and autopsy samples of thyroid, it was revealed that in cancer the small lymphocytes, in the total population of these lymphoid cells, comprise 0-2%, and on distributional histograms of lymphoid cells, according to the average diameter, the maximum was in the range of 9.6-11.7 microns. In benign malformations, goiters and autoimmune thyroiditis, and in the norm the percentage of small lymphocytes varied in the range of 10-44, with the maximum in the range of 7.5-9.6 microns. Histograms, built according to the space occupied by lymphoid cells, evidenced that in malignant thyroid disease a cupola-shaped character of distribution was peculiar, whereas in other pathologies and in norm the exponential relationship was revealed.
