Description: The most striking feature is the presence of neat hairpin vessels surrounded by a white halo. Several milia cysts (including a big one) and some "pseudo-comedos"are also visible.

History: This man regularly comes for his many seborrheic keratoses of the trunk and abdomen. (This image illustrates the white halo around hairpin vessels in elevated keratinising tumours such as seborrhoeic keratoses, warts, SCCs and keratoacanthomas. The whitish halo is composed of keratinocytes surrounding the feeding vessel. This white halo is not seen in melanocytic lesions. IMCC Editor)
