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).
