Placental pathology for the surgical pathologist.
Pathologic examination of the placenta is of clinical importance in the evaluation of pregnancies with a less than perfect outcome. Morphologic alterations of the placenta can mirror disorders of the fetus and the mother and evaluation of the placenta can identify clinically significant lesions, allow understanding of a child's disability and may have a role in resolving medical-legal disputes. Pathologic findings in the placenta can provide information on the pathogenesis of cerebral palsy, mental retardation, or neurodevelopmental disorders. This review will cover a variety of frequently encountered, clinically important, and morphologically distinct disorders of the placenta. The current understanding of the clinical implications of lesions for the mother, infant, and for future pregnancies will also be considered.
