To verify the mechanism of carcinogenesis by ultraviolet radiation of skin primary melanoma occurring in exposed areas by melanin ratio (Eumelanin/Pheomelanin) in epidermal stratum corneum.
Others
This study confirms the correlation between the degree of UV exposure and melanoma development by analyzing the ratio of Eumelanin to Pheomelanin in the perilesional and nonlesional areas of melanoma patients, exposed areas of healthy individuals, and nonexposed epidermal stratum corneum, and further tests whether the ratio of Eumelanin to Pheomelanin can be a predictive indicator for the risk of developing melanoma.
