  Chronic villitis is characterized by chorionic villi infiltrated by lymphocytes, histiocytes, and sometimes plasma cells. In a small percentage of cases, an infectious agent can be demonstrated within areas of chronic villitis. However, the pathogenesis of most lesions is idiopathic.
  Chronic villitis may represent the direct spread of chronic endometrial infection by bacterial organisms that are particularly problematic for culture.

  Synopsis
  The cross-sectional surface, number, and circumference of villous vessels only increase until the 20th week.
  The relative degree of vascularization increases further until 28th week together with a continuous decrease in villous size.
  Epithelial plates start to appear in the 18th to 20th week, and their development is essentially completed by the 28th week.
