Should we routinely check for hepatitis B and C in patients with lichen planus or cutaneous vasculitis?

The study aimed to determine the prevalence of HBs-Ag and anti-HCV antibodies in a group of 43 patients with lichen planus and 19 patients with cutaneous vasculitis versus 30 controls. The results showed that 12 [27.9%] patients with lichen planus were positive for HBs-Ag, 9 [20.9%] were positive for anti-HCV antibodies and 3 [7%] were positive for both. In cutaneous vasculitis patients, 3 [15.8%] were HBs-Ag-positive, 7 [36.8%] were anti-HCV-positive and 3 [15.8%] were positive for both. In the control group, 8 [26.7%] were HBs-Ag positive, 3 [10%] were anti-HCV-positive and 1 [3.3%] was positive for both. These values were not statistically significant
