Urticarial vasculitis is an entity characterized by urticarial rashes that are typically pruritic and painful, associated with angioedema and purpura. Influenza viruses are common respiratory pathogens that can cause seasonal infections and global human morbidity/mortality. A 4.5-year-old girl presented with fever and painful urticarial skin lesions leaving post-inflammatory hyperpigmentation. The nasal specimens showed a positive for influenza A/H1N1. On the basis of these findings, a diagnosis of urticarial vasculitis associated with A/H1N1 was concluded. Taking the results together, we suggest that urticarial vasculitic lesions can be considered to the list of cutaneous manifestations during the seasonal flu.

Objectives: To evaluate the prevalence and clinical associations of anti-C1q antibodies in IgG4-related disease (IgG4-RD), focusing on renal involvement and cutaneous small-vessel vasculitis (CSVV).
Methods: We enrolled patients who met the revised 2020 Comprehensive Diagnostic Criteria and/or the 2019 ACR/EULAR Classification Criteria for IgG4-RD. Variables included demographics, organ involvement, clinical phenotypes, disease activity, serum biomarkers, follow-up duration, remission, and relapses.
