That is much lower than I would expect. According to the AIUM monograph on the placenta by Lewis H. Nelson, III MD RDMS, page 25, lower levels of HCG were found with placental site trophoblastic tumor. However, the intrauterine mass that I imaged today does not seem to be invading the uterine wall, and invasion of the uterine wall evidently is a feature of placental site trophoblastic tumor. Time will tell. Here is the path report on the case I recently posted, probable gestational trophoblastic disease.
Sections show multiple portions of decidualized endometrium and chorionic villi.
The villi are variously enlarged, many of which demonstrate prominent cisternae. Other villi however, are normal in size. This information is provided for educational purposes only. Please read the disclaimer .
