There was extensive dermographism. Other systemic examinations were within normal limits. Haematological profile was normal except raised D-dimer. Skin biopsy revealed the presence of leucocytoclastic vasculitis. Antinuclear antibody was positive in a titre of 1\u2009:\u2009160, but antidouble-stranded DNA was negative. Urine examination revealed haematuria and proteinuria. Complement C<jats:sub>3,<\/jats:sub> C<jats:sub>4<\/jats:sub> and C<jats:sub>1q<\/jats:sub> levels were decreased with the presence of anti-C<jats:sub>1q<\/jats:sub> antibody. There was a diagnostic dilemma between systemic lupus erythematosus and hypocomplementaemic urticarial vasculitis syndrome. However, as the patient did not fulfil the American College of Rheumatology criteria for systemic lupus erythematosus, but fulfilled all the criteria for hypocomplementaemic urticarial vasculitis syndrome, the case was finally diagnosed as hypocomplementaemic urticarial vasculitis syndrome and treated accordingly with favourable outcome.<\/jats:p>","DOI":"10.1136\/bcr-2013-009082","type":"journal-article","created":{"date-parts":[[2013,5,23]],"date-time":"2013-05-23T08:55:26Z","timestamp":1369299326000},"page":"bcr2013009082","source":"Crossref","is-referenced-by-count":9,"title":["Hypocomplementaemic urticarial vasculitis syndrome: a mimicker of systemic lupus erythematosus"],"prefix":"10.1136","volume":"2013","author":[{"given":"Krishnendu","family":"Roy","sequence":"first","affiliation":[{"name":"Department of Medicine, Medical College Kolkata, Kolkata, West Bengal, India"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Arunansu","family":"Talukdar","sequence":"additional","affiliation":[{"name":"Department of Medicine, Medical College Kolkata, Kolkata, West Bengal, India"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Bappaditya","family":"Kumar","sequence":"additional","affiliation":[{"name":"Department of Medicine, Medical College Kolkata, Kolkata, West Bengal, India"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Sumanta","family":"Sarkar","sequence":"additional","affiliation":[{"name":"Department of Medicine, Medical College Kolkata, Kolkata, West Bengal, India"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"239","published-online":{"date-parts":[[2013,5,22]]},"reference":[{"key":"2025082722350825000_2013.may22_1.bcr2013009082.1","first-page":"458","article-title":"Urticaria: its history-based diagnosis and etiologically oriented treatment","volume":"2013","author":"Maurer","year":"2008","journal-title":"Dtsch Arztebl Int"},{"key":"2025082722350825000_2013.may22_1.bcr2013009082.2","doi-asserted-by":"crossref","first-page":"146","DOI":"10.1007\/s12019-003-0018-3","article-title":"Urticaria and urticarial vasculitis","volume":"2013","author":"Guha","year":"2003","journal-title":"Comp Ther"},{"key":"2025082722350825000_2013.may22_1.bcr2013009082.3","doi-asserted-by":"crossref","first-page":"441","DOI":"10.1016\/0190-9622(92)70069-R","article-title":"Urticarial vasculitis: a histopathologic and clinical review of 72 cases","volume":"2013","author":"Mehregan","year":"1992","journal-title":"J Am Acad Dematol"},{"key":"2025082722350825000_2013.may22_1.bcr2013009082.4","doi-asserted-by":"crossref","first-page":"24","DOI":"10.1097\/00002281-200001000-00005","article-title":"Urticarial vasculitis","volume":"2013","author":"Wisnieski","year":"2000","journal-title":"Curr Opin Rheumatol"},{"key":"2025082722350825000_2013.may22_1.bcr2013009082.5","first-page":"884","article-title":"IgG autoantibody to collagen like region of C1q in hypocomplementemic urticarial vasculitic syndrome, systemic lupus erythematosus and 6 other musculoskeletal or rheumatic diseases","volume":"2013","author":"Wisnieski","year":"1992","journal-title":"J Rheumatol"},{"key":"2025082722350825000_2013.may22_1.bcr2013009082.6","first-page":"231","article-title":"Hypocomplementemic urticarial vasculitis: association with chronic obstructive pulmonary disease","volume":"2013","author":"Schwartz","year":"1982","journal-title":"Mayo Clinic Proc"},{"key":"2025082722350825000_2013.may22_1.bcr2013009082.7","doi-asserted-by":"crossref","first-page":"899","DOI":"10.1016\/S0190-9622(24)00193-2","article-title":"Clinicopathologic corelation of hypocomplementemic and normocomplementemic.
