absence (0) of 12 clinical features typical for basal cell carcinomas according to Tognetti and Lallas et al. classification (in authors' modification).Each dermoscopic observation was performed in search for presence (1) or absence (0) of 61 dermoscopic features typical for basal cell carcinoma according to the third consensus of the International Dermoscopic Society.Database of 10209 clinical and dermoscopic observations was analyzed Results: No relapses were reported.In two year observation HDR brachytherapy reduces number of most clinical and dermoscopic patterns typical for basal cell carcinoma.Exceptions were: clinically observed telangiectasia and pigmented structures and dermoscopically observed white structureless areas and monomorphous thin linear vessels.Observed image corresponds with typical clinical presentation of late skin radiation toxicity.Conclusions: In 24 months observation HDR brachytherapy reduces number of clinical and dermoscopic patterns typical for basal cell carcinoma.Tumor bed after radiation treatment presents as clinically observed depigmented area with pigmented structures and teleangiectasia.Dermoscopically presents as large white structureless area with thin linear, monomorphous vessels.
