Colchicine treatment of urticarial vasculitis

A patient with clinically and histologically typical urticarial vasculitis has been treated with 0.5 mg of colchicine three times per day. This treatment resulted in both disappearance of urticarial skin lesions and amelioration of severe systemic symptoms such as abdominal pain, fever and arthralgia. Colchicine is proposed as an effective therapeutic agent for urticarial vasculitis if other drugs are ineffective, poorly tolerated or contraindicated.
