Pemphigoid gestationis: a case report and review of the literature.

Pemphigoid gestationis (PG) is an uncommon autoimmune bullous disease that almost exclusively presents during pregnancy. Patients typically present with a diffuse blistering and intensely pruritic eruption that begins periumbilically and spreads to involve the rest of the body. Direct immunofluorescence demonstrating C3 in a linear pattern along the dermoepidermal junction confirms the diagnosis of PG. Corticosteroids remain the choice of therapy and early intervention is essential because of possible adverse effects of PG on the fetus. We report a case of PG and review the literature.
