Caracteristics of women presenting with chronic histiocytic intervillositis during pregnancy: A case-control study.

Introduction: Chronic Histiocytic Intervillositis (CHI) appears to be among the most severe placental diseases. Its rarity has limited our knowledge of the women in whom it occurs.

Objective: To search for maternal characteristics linked to the existence of CHI, by first studying the current pregnancy included in the study, then their previous pregnancies.
