[Gestational herpes. Presentation of a case and review of the literature].

Herpes gestationis (HG) is a rare autoimmune blistering complication of pregnancy. It is of unknown etiology and it occurs once in every 3,000 to 50,000 pregnancies. The diagnosis can strongly be suggested by the clinical picture, but it must be confirmed using immunopathological methods. The treatment of choice is local measures and systemic corticosteroids. Although the maternal prognosis is excellent, there are controversies on the perinatal outcome. A typical case of HG is presented and the literature is reviewed.
