title: HLA molecule expression in cutaneous squamous cell carcinomas: an immunopathological study and clinical-immunohistopathological correlations.
abstract: A correlation between the lack of MHC class I gene expression on murine tumor cells and their ability to grow and metastasize has recently been established. This paper studies HLA-ABC and HLA-DR antigen expression in tumor cells and mononuclear infiltrate of 26 cutaneous squamous cell carcinomas (SCC). Our results showed a heterogeneous expression of HLA class I molecules in these tumors. No significant correlation between the degree of HLA class I molecule expression and anatomical-clinical parameters was found. Class II antigen expression was correlated to the histopathological type and to the degree of cell differentiation. Most mononuclear cells infiltrating the tumor were T-lymphocytes. No correlation with anatomical-clinical parameters was found.
