Dermal C4d Deposition and Neutrophil Alignment Along the Dermal–Epidermal Junction as a Diagnostic Adjunct for Hypocomplementemic Urticarial Vasculitis (Anti-C1q Vasculitis) and Underlying Systemic Disease

This study shows that both the alignment of neutrophils along the DEJ and dermal C4d deposition are strongly associated with HUV and SLE. Therefore, these (immuno)histopathological features can be used as an easy diagnostic adjunct for early detection of underlying systemic disease in UV.
