Urticaria and urticarial vasculitis
Common urticaria is dermoscopically characterized by a red, reticular network of linear vessels, which may be surrounded by an area devoid of vessels, corresponding to dermal edema.[1] On the contrary, urticarial vasculitis dermoscopically exhibit purpuric dots or globules on an orange-brown background.[2] Both diseases reveal no highly specific criteria, but the presence of purpuric dots is suggestive of an underlying vasculitis.
