Description: Macro image- Lentigo maligna melanoma was present along the entire length of this scar which leads to the assertion that much of this recurrent lentigo maligna melanoma was "invisible" both clinically and dermoscopically.
History: This 71 year old lady presented with this macule in continuity with a scar 4 years after excision of a level 4 lentigo maligna melanoma which had been excised with 1.5 mm clearance at the closest margin. The initial exision biopsy of the pigmented macule at the lower end of the scar revealed level 1 lentigo maligna melanoma involving the entirety of both margins. Two further attempts at surgical clearance resulted finally in a level 1 lentigo maligna melanoma with lateral clearance of greater than 10 mm.
