The frequencies of human leukocyte antigens--HLA-A, HLA-B, HLA-C, HLA-DR, and HLA-DQ1--were determined in a group of 40 white British patients with oral lichen planus and compared with those of healthy controls. Alterations in the frequencies of several HLA antigens were noted. In particular, an increase in HLA-Bw57 and a decrease in the frequency of HLA-DQ1 were seen in the group with lichen planus. When different clinical subgroups of lichen planus were compared with the control group, significant changes were also noted in the frequencies of HLA antigens. This suggests that lichen planus may represent a heterogeneity of diseases and that HLA-Bw57 may predispose a person to lichen planus whereas HLA-DQ1 may be associated with resistance to it.
