Trace elements in skin epitheliomasTrace elements in skin epitheliomas Peer-Reviewed Journal Publication Δημοσίευση σε Περιοδικό με Κριτές 2015-12-021987enSkin tissue samples from 41 patients suffering from skin epitheliomas were analyzed by the PIXE method. Skin samples from the non-affected areas and blood serum were also analyzed for the same patients. The elements determined were K, Ca, Cr, Mn, Fe, Ni, Cu, Zn, Br, Rb, and Pb. Their concentrations in the healthy skin and the serum were normal. The concentrations in the lesions were nearly the same for both basal cell and squamus cell epitheliomas (BCE and SCC) except for higher zinc and lower bromine values in the BCE samples. However, substantial differences were observed between the affected and non-affected skin.http://creativecommons.org/licenses/by/4.0/Journal of Radioanalytical and Nuclear Chemistry109189-100 Papassotiriou, Vassilios S.
