Description
The aim of this work is to evaluate the concentrations of trace elements content in seborrhoeic keratosis (SK) skin lesions as well in normal skin and compare them. These data was acquired by Synchrotron Radiation Total Reflection X-ray Fluorescence (SRTXRF). It focused elements with atomic number greater than 14. This stage of research was supported by LNLS - Brazilian Synchrotron Light Laboratory in Campinas/Sao Paulo-Brazil. The collection of lesion and healthy skin samples, including papillary dermis and epidermis, from the same patient, has involved 5 males and females with ages varying from 34 to 80 years old. The results have shown the presence of P, S, Cl, K, Ca, Ti, Cr, Fe, Ni, Cu, and Zn in healthy skin. The comparison with lesion contents has revealed significant differences in contents of Fe, K, Cr, and Zn. (author)
