hairpin vessels in a seborrhoeic keratosis

This lesion presented as a 18 by 12 mm scaly plaque on the trunk.

The plain view shows well organised keratin plates with a fissure between them. This is pretty typical of a seborrhoiec keratosis

??????????????????????????????? ??????????????????????????????? ???????????????????????????????

The lesion was too large to photograph in one piece. 2 dermoscopic images of edges are shown.

we see surface keratin and radial looped/hairpin vessels, very clear examples.

Its a seborrhoiec keratosis. You can see radial hairpin vessels in a squamous cell cancer, but that would be a faster growing lesion with a nodular rather than a plaque configuration.

    Many thanks for this. I attended your course in Birmingham in September and it was fantastic. It really helped to motivate me to learn more about dermoscopy and your web site and blog are a great resource for learning. Thank you for all the work you are putting in to spread the word about dermoscopy in primary care. Best wishes, Charlie Berrisford.
