<p>This elderly lady had a lesion on the right shin. She felt it had been present for quite a long time and was uncertain as to whether or not it had changed. What do you make of the dermoscopic features and how would you manage this case?</p>

<p>Are we seeing grouped smooth clods here, in which case we should consider a probable melanocytic lesion? If so we may be concerned.</p>
<p><strong>Just occasionally</strong> a lesion has grouped brown clods that are non-melanocytic. The more reassuring features to this case include an even brown colour and a <strong>well-demarcated border (black arrows)</strong> more in keeping with a solar lentigo. The structures circled appear to be starting to stretch out and as such could represent <strong>very early pigment bands</strong>, structures we see in thin seborrhoeic keratoses. Some solar lentigines will develop features of a seborrhoeic keratosis.</p>
<p>I was following the patient up for another matter so simply observed this lesion, which was flat - three months later the lesion was unchanged and the diagnosis in keeping with a solar lentigo/thin seborrhoeic keratosis.</p>
<p>It would have been totally reasonable to refer this lady urgently as a 2-week wait.</p>
