What dose-fractionation and technique do you use when treating lentigo maligna?  

57.5 Gy/23 fractions using superficial (100 kv) radiotherapy in most situations, as long as the target is not too large. There are a variety of dose fraction schemes used which are generally dependent on technique (Grenz, orthovoltage, skin surface brachytherapy, megavoltage electrons), but this is ...

Lentigo maligna is generally considered a precursor to developing malignant melanoma. Although it is a less aggressive lesion the treatment is quite similar. If the lesion has been completely excised with wide clear margins, I would recommend no further treatment. If it is post biopsy and no further...

Thank you both for your answers. There is a recent open-access review that tabulates dose and technique for this clinical scenario. This is a shareable link: https://rdcu.be/b6fcP. This one also: https://www.ncbi.nlm.nih.gov/pubmed/24032599/
