• A 28-year-old woman had an intensely pruritic eruption, consisting of plaques and vesicobullous lesions, three days after removal of a hydatidiform mole. Direct immunofluorescence (IF) microscopy of involved skin showed the linear deposition of C3 but no immunoglobulin along the basement membrane zone. Indirect IF microscopy disclosed a serum complement-fixing IgG antibody that reacted with the basement membrane of human adult and fetal skin. Thus, herpes gestationis can occur in association with a hydatidiform mole.
