HLA pattern in patients with lichenoid drug exanthem

: 27 patients suffering from lichenoid drug eruption have been studied with special reference to histocompatibility standardisation. In comparison with a control group (n = 54), our patients revealed high and statistically significant levels of HLA-A1, HLA-B8, and HLA-DR3 (p less than 0.05). These results are discussed with particular regard to HLA patterns previously obtained in lichen planus.
