Multiple skin biopsies were taken for immunohistochemical evaluation of ATG7 expression.Results: Both epithelial and stromal ATG7 were expressed in all participants while all patients showed nucleocytoplasmic localization and controls showed both cytoplasmic and nucleocytoplasmic expression. In addition, significantly higher H-scores of ATG7 in both epithelium and stroma were detected in patients compared to controls (P< 0.001).Conclusion: ATG7 nucleocytoplasmic topographic localization might be involved in the pathogenesis of NMSC, which can open the gate for new target therapy for this skin cancer.Keywords: autophagy, autophagy related gene 7, BCC, SCC, NMSC
