Hypocomplementemic urticarial vasculitis and lower cranial nerve palsies.

A 55 years post menopausal lady presented with puffiness of face, and a pruritic urticarial rash over face and upper trunk of one week duration with accompanying dysphagia. Clinical examination revealed an urticarial rash over face and upper trunk, two small ulcers over floor of mouth and evidence of bilateral VIII, IX and Xth cranial nerve palsies. Hypocomplementemia, negative immune profile and evidence of vasculitis on skin biopsy suggested a diagnosis of hypocomplementemic urticarial vasculitis. The patient responded to a course of steroids.
