title: Pathologic examination of fetal and placental tissue obtained by dilation and evacuation.
abstract: BACKGROUND
  Dilation and evacuation (D&E) is an alternative method to induction of labor for pregnancy termination and intrauterine fetal demise, and it is the most common mode of second-trimester uterine evacuation in the United States. Many D&E specimens are examined in surgical pathology, and there is little information available in surgical pathology textbooks or the literature to assist pathologists in these examinations.
  
  
  OBJECTIVE
  To provide an overview of the D&E procedure, discuss related legal issues, provide guidelines for routine pathologic examination of D&E specimens, and demonstrate the importance of careful pathologic examination of D&E specimens.
  
  
  METHODS
  Case-derived material and literature review.
  
  
  CONCLUSIONS
  Pathologic examination of D&E specimens has been understudied. However, the available literature and our experience support the fact that careful pathologic examination of D&E specimens can identify significant fetal and placental changes that can confirm clinical diagnoses or provide definitive diagnosis, assist in explaining the cause of intrauterine fetal demise, and identify unexpected anomalies that may provide further clues to a diagnostic syndrome or mechanism of anomaly formation.
