Introduction
The pathogenesis of basal cell carcinoma (BCC) is multifactorial and not fully elucidated. Previous studies showed that behaviour of the tumour may be influenced by the immune system and identified CD4+CD25+FoxP3+ regulatory T cells (Tregs) as dominant immune cells in BCC microenvironment. The function and development of Tregs is regulated by FOXP3, encoding transcription factor Forkhead box P3. FOXP3 regulates transcription of many genes, including up-regulation of cytotoxic lymphocyte-associated antigen-4 gene (CTLA-4). Expressed on Tregs, CTLA-4 interacts with antigen-presenting cells to inhibit T-cell activation.

Aim
To investigate the role of two polymorphisms (rs3761548 and rs2232365) of FOXP3 and CTLA-4 polymorphism (rs5742909) in BCC patients from northern Poland.

Material and methods
We analysed 280 unrelated patients with BCC of mean age 70.93 ±11.53 (70.54 ±12.55 women, 71.38 ±10.26 men) and 200 healthy, unrelated age- and sex-matched volunteers.

Results
The differences in the occurrence of BCC between genotypes and alleles of the analysed polymorphisms were not statistically significant. In the studied group, the presence of the CC genotype in CTLA-4 rs5742909 polymorphism was statistically more frequent in patients with multiple BCCs.

Conclusions
It seems that the analysed FOXP3 and CTLA-4 polymorphisms do not influence the BCC susceptibility. CTLA-4 rs5742909 polymorphism may influence the susceptibility to multiple BCCs.
