Urticaria and urticarial vasculitis

Common urticaria is dermoscopically characterized by a red, reticular network of linear vesselsLinear mildly curved vessels considered irregular when different sizes shapes and curves with a haphazard or random distribution are presented and considered regular when short and fine (thin) linear vessels prevail various diagnoses, which may be surrounded by an area devoid of vesselsThis glossary term has not yet been described., 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 criteriameasure of how well one variable or set of variables predicts an outcome, but the presence of purpuric dots is suggestive of an underlying vasculitis.
