Pemphigoid gestationis is less common among blacks than whites, which might reflect its association with specific HLA haplotypes.
Findings from European studies suggest that pemphigoid gestationis has an overall incidence of 0.5 cases per million people per year. In 1999, Jenkins et al [8] described the largest cohort of 87 patients in the United Kingdom with a total of 278 pregnancies, of which 142 were complicated by pemphigoid gestationis.
Pemphigoid gestationis occurs in women of childbearing age.
In the United States, pemphigoid gestationis has an estimated prevalence of 1 case in 50,000 pregnancies.
