Placental Implantation: A Morphologic Review (Mar 12, 2022 - Mar 11, 2027)

Placental Implantation: A Morphologic Review is organized by Opus Medicus, Inc.

Course Dates:
Last Review Date: 11-Mar-2024
Expiration Date: 11-Mar-2025

Description:
This course describes the normal development of the placenta from the unique perspective of the implantation site. Diseases that affect the invasion of maternal tissue by fetal trophoblast, a major cause of morbidity during pregnancy, will be discussed including:

Topics:

• Ectopic (tubal) pregnancy
• Invasive implantation (Placenta accreta, increta, percreta)
• Vascular abnormalities of implantation (Growth restriction, pre-eclampsia)
• Tumors of intermediate trophoblast:
  • Exaggerated placental site (EPS)
  • Placental site trophoblastic tumor (PSTT)
  • Placental site nodule (PSN)
  • Epithelioid trophoblastic tumor (ETT)

Objectives:

• Describe the morphologic changes in the placental bed during normal pregnancy
• Define subtypes of non-villous trophoblast and their functions in the placental bed
• Describe major diseases that affect or are caused by abnormalities of implantation
