Placental Implantation: A Morphologic Review (Mar 12, 2022 - Mar 11, 2025)
Placental Implantation: A Morphologic Review is organized by Opus Medicus, Inc.
Course Dates:
Last Review Date: 12-Mar-2022
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
