Chronic intervillositis of unknown etiology (CIUE) is a rare placental pathology first described by Labarrere and Mullen in 1987 1.It is histologically characterized by extensive leukocyte infiltration of the intervillous space, primarily by mononuclear cells of maternal origin 1, 2.The immune cell infiltration is associated with local inflammation of the intervillous space and . Infiltrating cells have been shown to be maternal T cells, suggesting that this is an immune mediated disease. The twins with placental involvement by CVUE had a lower mean birthweight than their cotwins with less or no CVUE; however, these results were not statistically significant.

Am J Clin Pathol. Chronic villitis of unknown etiology (CVUE) is a frequently encountered placental lesion associated with poor pregnancy outcome. As chronic deciduitis is associated with other chronic inflammatory lesions, especially basal chronic villitis [2, 10], the presence of basal chronic villitis should prompt a search for chronic deciduitis. Associations with italicized odds ratios and confidence intervals that . Within chronic villitis there is a major etiologic division into infectious villitis versus villitis of unknown etiology (VUE).
