The relation between 2 DNA-repair systems was investigated in 3 groups of naevi (naevus cell naevi, dysplastic naevi, fibromatous naevi) using the correlation coefficient according to Spearman. In the group of naevus cell naevi, only 1 significant correlation between MSH2 and GADD34 expression was found. In the group of dysplastic naevi, 9 significant and highly significant correlations between GADD genes and mismatch repair genes were found. In the group of fibromatous naevi, MLH1 correlated significantly with GADD45 and highly significant with GADD34 expression. Different correlations in naevi groups investigated show the different functional connections between the genes of DNA repair.

Thirty-one naevus cell naevi, 30 dysplastic naevi and 12 fibromatous naevi were stained for the presence of p53 and Growth Arrest DNA Damage genes. All naevus cell naevi and fibromatous naevi were highly positive for GADD genes and negative for p53. Dysplastic naevi had significantly lower GADD34 and GADD153 expression as well as higher p53 expression in relation to the other naevi groups. The absence or decrease of GADD genes expression in naevus may indicate a potential malignant transformation.
