| Summary: | The pathogenesis of mycosis fungoides (MF) is not fully understood, nevertheless it is believed that the microenvironment of the tumor cells could influence the development of malignant lymphocytes. T-regulatory cells are a specialized subpopulation of T-lymphocytes, which can have an immunosuppressive effect and thus affect the immune response. Goal. The study population of regulatory T-cells in the skin of patients with mycosis fungoides and llaque parapsoriasis. Materials and methods. The content of Foxp3+ and CD3+ cells by immunohistochemical studies of skin biopsy specimens from patients with patch stage mycosis fungoides (10 patients) and plaque parapsoriasis (10 patients). The control group consisted of 16 healthy individuals. Results. Relative expression area Foxp3+ cells in patients with mycosis fungoides patch stage (0.44%) 2.6 times greater than in patients with plaque parapsoriasis (0,14%; p < 0,05). Part the Foxp3+ cells of the total number of T lymphocytes in patients with patch stage mycosis fungoides (5.9%) and plaque parapsoriasis (4.7%) were not significantly different (p > 0,05). Conclusion. In the initial stage of patients with mycosis fungoides determined a statistically significant predominance of the absolute number of T-regulatory cells in the epidermis and in the dermis. Part T-regulatory cells from all of T-lymphocytes in patients with skin patch stage mycosis fungoides and plaque parapsoriasis not statistically significantly different. |
