title: [The evaluation of the relationship between malignancy grade and cytokeratin-10 accumulation in human skin squamous cell carcinoma].
abstract: The aim of the study was analysis of CK-10 expression in human skin squamous cell carcinoma (SCC) basing on immunohistochemical procedure. The study was carried out on 43 samples of skin SCC which were evaluated histopathologically with regard to 3-grade scale (G) of malignancy. In each case immunohistochemical reactions by use of ABC method were carried out in order to detect CK-10 within cancer cells. The expression of CK-10 was evaluated in accordance with arbitrary 3 grade scale: from +++ to +. The obtained results revealed affection of CK-10 expression in cancer cells. In G1 and G2 skin SCC a moderate expression of CK-10 was found and this occurred in cells grouped in nests. In G3 SCC the expression of CK-10 was very low and this was noted in single cells only. The use of immunohistochemical methods in evaluation of CK-10 expression can be a useful tool in routine histopathologic examination of tumors of epithelial origin.
