[Pemphigoid gestationis: light microscopic and direct immunofluorescense findings].

Pemphigoid gestationis is a rare vesiculobullous dermatosis of pregnancy and puerperium. It is commonly seen in second or third trimester. Skin lesions are characterized by pruritic, urticarial plaques with the development of tense vesicles and bullae. Histopathology demonstrates a subepidermal eosinophil-rich vesiculation. Direct immunofluorescence microscopy reveals linear complement 3 and immunoglobulin G deposition along the basement membrane. We present a rare case of pemphigoid gestationis occurring in a 33-year-old pregnancy woman with symptom of generalized pruritis. Pemphigoid gestationis should be kept in mind in the differential diagnosis of vesiculobullous dermatitis of pregnancy.
