BMJ Case Rep. 2021 May 10;14(5):e240041. doi: 10.1136/bcr-2020-240041.

Abstract

Hypocomplementemic urticarial vasculitis syndrome (HUVS) is a rare autoimmune disorder characterised by recurrent urticarial lesions and acquired hypocomplementemia with systemic manifestations. The authors present the case of a 70-year-old man who presented to the ophthalmology clinic with bilateral scleritis and ocular hypertension. He was diagnosed with HUVS after a 6-month period of bilateral scleritis, vestibulitis, significant weight loss, mononeuritis multiplex and recurrent urticarial vasculitis with pronounced persistent hypocomplementemia and the presence of anti-C1q antibodies. Disease control was eventually obtained with mycophenolate and prednisolone.

Keywords: dermatology; immunology; ophthalmology; vasculitis.
