Experience with Treating Lentigo Maligna with Definitive Radiotherapy

Figure 9

The depth of skin is on the X axis, the amount of radiotherapy is on the Y axis. Brachytherapy and superficial radiotherapy give good dose to skin surface and at 5 mm but do give significant dose to dermis which may lead to increased late effects, for example, fibrosis, telangiectasia in the future. Electrons do give a good drop-off in dose so there is less dose to dermis.
