Chorion. Placental site trophoblastic tumor [PSTT] and epithelioid trophoblastic tumor [ETT] are the rarest gestational trophoblastic neoplasias, developing from intermediate trophoblast of the implantation site and chorion leave, respectively. PSTT and ETT share some clinical-pathological features, such as .
Gestational Trophoblastic Tumors A Timely Review of Diagnostic Pathology Pei Hui, MD, PhD Context.—Gestational trophoblastic tumors include 3 distinct entities: gestational choriocarcinoma, placental site trophoblastic tumor, and epithelioid trophoblastic tumor. Accurate diagnosis is important for clinical management of the patient. Part of the highly regarded Diagnostic Pathology series this updated volume covers all aspects of placental pathology and the critical role the placenta plays in the unique interface between mother and fetus. Concise focused chapters supported by tables diagrams and photographs keep you up-to-date with evolving changes in the questions and issues concerning both the .
Placental site trophoblastic tumor (PSTT). Aggregates of neoplastic cells may not only be associated with zonal necrosis but also show prominent arterial remodeling recapitulating the appearance of the normal implantation site. Trophoblast is part of a normal blasts are derived from the conceptus, i.e. not maternal. Part of the trophoblast forms chorionic villi.. Tumours arising from the trophoblast are dealt with in gestational trophoblastic disease.

Invasion of the trophoblast too deeply may cause conditions such as placenta accreta, placenta increta, or placenta percreta.
Gestational trophoblastic disease is a pregnancy-associated concept, forming from the villous and extravillous trophoblast cells in the rise to: caul. Placental site trophoblastic tumor is a neoplasm of extravillous intermediate trophoblast at the implantation site, preceded in the majority of cases by a female gestational event.
Pre-Implantation. The development of the placenta begins during implantation of the blastocyst. The cell blastocyst contains two distinct differentiated embryonic cell types: the outer trophoblast cells and the inner cell mass.
The trophoblast cells form the placenta. The inner cell mass forms the foetus and foetal membranes/5. placenta serves as the interface between the mother and the developing fetus. The placental trophoblasts are critical for a successful pregnancy by mediating such critical steps as implantation, pregnancy hormone production, immune protection of the fetus, increase in maternal vascular blood flow into the placenta, and delivery.

In this volume Dr Hui has brought together a comprehensive overview of gestational trophoblastic disease that includes all the currently recognized entities: complete and partial hydatidiform moles, placental site trophoblastic tumor, epithelioid trophoblastic tumor, gestational choriocarcinoma, persistent gestational trophoblastic neoplasia, placental site nodule and exaggerated placental.
The Placenta: From Development to Disease is ideal for both experienced clinicians and researchers and those new to the field. Anyone who needs to understand the central importance of the placenta in the well being of their maternal and fetal patients should read this book.

PSTT, a neoplasm of implantation site intermediate trophoblastic cells, is a rare form of gestational trophoblastic disease (GTD) 3% of GTD cases.
Other previously used terms are atypical choriocarcinoma, syncytioma, chorioepitheliosis and trophoblastic pseudotumor. Normal placenta tissue and hydatidiform mole tissue can become a kind of malignancy.
This is known as gestational trophoblastic neoplasm (GTN). The most common malignancy is choriocarcinoma, a type of over-invading pregnancy implantation. Less common neoplasms include placental site trophoblastic tumor (PSTT) and epithelial trophoblastic tumor.
PD-L1 immunoreactivity in placental site trophoblastic tumor (PSTT) and epithelioid trophoblastic tumor (ETT). A and B. Two PSTTs show PD-L1 immunostaining but the intensity is lower than that in syncytiotrophoblast.
An ETT demonstrates focal and weak PD-L1 staining. Another ETT demonstrates an undetectable PD-L1expression level. Gestational trophoblastic disease (GTD) means different things to the pathologist and the clinician. The pathologist utilizes a classification based on histopathology, while the clinician uses a clinically based classification, and does not always need to submit tissue for histopathology to appropriately manage the patient, particularly with post‐molar GTD (Table 1).
Formalin-fixed tissue samples from 24 normal implantation sites, 19 exaggerated placental sites, five molar implantation sites, 16 placental site trophoblastic tumors, and 12 choriocarcinomas were stained with a Mel-CAM-specific polyclonal antibody and a Ki antibody using streptavidin-biotin immunoperoxidase with two different chromagens.
Placental site trophoblastic tumour (PSTT) is a rare gestational trophoblastic disease (GTD), arising from the transformation of implantation intermediate trophoblast following a full-term. Introduction. Placental site trophoblastic tumor (PSTT) is a rare form of gestational trophoblastic disease arising from invasive intermediate gestational trophoblasts and constitutes 1–2% of all GTN.

Fewer than 5 women are diagnosed in the UK with PSTT each year. They are part of a group of conditions called gestational trophoblastic disease (GTD for short).
Less than 1 in (1%) GTDs are placental site trophoblastic tumours.Gestational trophoblastic disease (GTD) is a term used for a group of pregnancy-related tumours are rare, and they appear when cells in the womb start to proliferate uncontrollably.
The cells that form gestational trophoblastic tumours are called trophoblasts and come from tissue that grows to form the placenta during pregnancy. There are several .Gestational trophoblastic disease is the name for a group of rare tumors that are usually related to pregnancy.
