History: This gentleman with no previous history of melanomas presented for a skin examination and this lesion was noticed. I was unsure whether it was melanocytic so performed a punch biopsy. The report stated that it was a benign dysplastic naevus. Because it was melanocytic an excision biopsy was performed which was reported as a level 2 melanoma with a Breslow thickness of 0.7mm. A third procedure was then necessary to achieve appropriate margins.
