Schönlein-Henoch purpura during pregnancy with successful outcome for mother and newborn

BACKGROUND Schönlein-Henoch purpura is a systemic vasculitis that affects vessels of a small caliber and rarely reported in the literature. CASE PRESENTATION We report on a 35-year-old woman who developed palpable purpura with necrotizing cutaneous lesions on the lower limbs at 27 weeks of gestation. She also complained of epigastric pain and arthralgias. Histologic examination of a skin biopsy showed leukocytoclastic vasculitis with intravascular fibrin thrombi. The direct immunofluorescence analysis evidenced vascular deposits of IgA and C3 in the upper and mid-dermis. These findings were consistent with Schönlein-Henoch purpura. There was no evidence of renal involvement or placental dysfunction. The patient was treated with low-dose oral corticosteroids and a healthy infant was delivered by cesarean section. Examination of the placenta and the navel string disclosed no signs of vasculitis or infarction. CONCLUSION Schönlein-Henoch purpura is rarely reported in pregnancy. Treatment with orally administered corticosteroids may lead to a beneficial outcome for mother and newborn.
