Deep dives

Understanding Urticarial Vasculitis

Urticarial Vasculitis is a distinct condition involving skin lesions that can last longer than 24 hours and often leave ecchymotic changes. Unlike typical hives, which are itchy, these lesions have a burning sensation and tend to occur more on the torso rather than the extremities. Notably, this condition is associated with systemic manifestations like abdominal pain, joint pain, and potential glomerular nephritis. Hypocomplementemic Urticarial Vasculitis is linked to more severe systemic involvement, while normal complementemic cases show a less intense presentation.
