Experience with Treating Lentigo Maligna with Definitive Radiotherapy

Figure 3

(a) This lady had a large area of lentigo maligna that has failed a surgical graft mapped out on her right medial cheek. The radiation oncologist has duplicated the RCM area onto that face. At least a 1 cm margin is then put around that area to act as field edge. (b) The radiation therapists have then produced a template on a piece of plastic which will be used to transfer marks onto the mask and will be used every day for treatment verification on the machine. This piece of plastic can be stored in an electronic medical records system and be emailed to a dermatologist or any other caring doctor in the future if the radiotherapy area is ever needed to be delineated or known, for example, if there is recurrence of lentigo maligna and the team wants to know whether the lentigo maligna recurrence is in-field or not or a field edge recurrence.
