urticarial vasculitis

ur·ti·car·i·al vas·cu·li·tis

painful, purpuric cutaneous lesions resembling urticaria but lasting longer than 24 hours, with biopsy findings of leukocytoclastic vasculitis and variable systemic changes, often with hypocomplementemia.

urticarial vasculitis

A clinical form of hypersensitivity vasculitis characterised by urticarial wheals and angioedema, which tend to persist longer than common chronic urticaria. Urticarial vasculitis may trigger systemic involvement in the form of renal failure, especially in those with concomitant hypocomplementaemia.

Associations
Hepatitis-B virus, Sjögren syndrome, systemic lupus erythematosus, myeloma, IgM gammopathy, pregnancy, cancer, solar urticaria, cold urticaria, and drugs (e.g., diltiazem).

Again according to this guideline conditions which are accompanied by urticaria including pigmented urticaria (cutaneous mastocytosis), urticarial vasculitis, familial cold urticaria and non-histaminergic angioedema (congenital or aquired C1 esterase inhibitor deficiency) were not included in the classification of urticaria, because they are caused by different mechanisms (13,14).
An important variant to mention is urticarial vasculitis, which on initial presentation presents like urticaria but the lesions are non-migratory, last for more than 24 hours and resolve with postinflammatory hyperpigmentation.
Urticarial vasculitis should be managed in the same way as urticaria.
