Case presentations

Case 1

A 52-year-old woman presented for a skin check with no particular concerns. There was a family history of melanoma but her naevus pattern was otherwise not particularly high risk. A pigmented lesion was prominent over the patient’s posterior thigh (Figure 1). As it was largely out of sight, she was unable to give a clear history of its duration and whether there had been any change over time.
