Experience with Treating Lentigo Maligna with Definitive Radiotherapy

Figure 12

Recurrent LM postsurgery at a dose of 50 of 60 Gy to skin the flap from the lower anterior right neck on face does not get an acute effect. This lady had LM and a large flap to the right medial cheek had failed to clear it. Salvage RT was given. At 50 Gy the surrounding skin is red but the flap is not. The mechanism behind this could be that the flap is relatively hypoxic to the skin and therefore does not exhibit radiation side effects like the normal skin does.
