Ten Years experience using the Johnson Square Procedure for Lentigo Maligna

Abstract

Lentigo maligna (LM) accounts for 4‐15% of all melanomas with risk of progression to lentigo maligna melanoma (LMM) estimated to be as high as 20% or as low as 5%. Due to the size, location and sub‐clinical spread of these lesions, margin control can be difficult. Clearance rates 24‐70% have been reported when using standard excision with 5mm margins and bread‐loaf histological processing Recurrence rates of 7‐20%.
