Gestational pemphigoid

Description

Gestational pemphigoid (pemphigoid gestationis) is an autoimmune skin disease characterised by pruritic plaques and blister formation on the skin in association with pregnancy or the trophoblastic tumours, hydatiform mole and choriocarcinoma. The exact causes of the disease are unknown but the disease is mediated by auto-antibodies to the hemidesmosome component BP180/BPAg2/collagen XVII. The maternal antibodies may cause short lived disease in the neonate, neonatal pemphigoid gestationis. This disease is not an infection with herpes virus despite its old name, herpes gestationis.
