（重定向自Pemphigoid gestationis）
Gestational pemphigoid or pemphigoid gestationis (PG) is a dermatosis of pregnancy, being an autoimmune blistering skin disease that occurs during pregnancy, typically in the second or third trimester, and/or immediately following pregnancy. It was originally called herpes gestationis because of the blistering appearance, although it is not associated with the herpes virus.
