Description: Abrupt border

History: This 58 year old lady with no past history of skin malignancy was having a general medical examination. She was not concerned by this lesion but when interrogated she thought it had only appeared in the "last few years". I thought that the pigment ended abruptly at the inferior border and dermoscopically there was a hint of blue-grey just superior to this. The pathologist confirmed that the "melanoma" histology was confined to that focus.
