Compared with hydatidiform mole, invasive hydatidiform mole and choriocarcinoma, the diagnosis of PSTT is more complicated and lacks specific and sensitive tumor markers. Most PSTT patients demonstrate malignant potential, and the primary treatment of.
The usual term placenta is about 22 cm in diameter and 2.0 to 2.5 cm thick. It generally weighs approximately 470 g (about 1 lb). However, the measurements can vary considerably, and placentas.

A Case Study and Grossing Protocol Proposal for Placental Site Trophoblastic Tumours INTRODUCTION Placental site trophoblastic tumours (PSTT) are a rare subset of gestational trophoblastic disease (GTD). Patients present with a hypervascular uterine mass, amenorrhea and post-partum low-level beta-human chorionic gonadotropin (beta hCG) elevation located over the necrotic nodule found at hysterectomy, suggesting that this was the site of origin. Additionally, the tumor extended to placenta and onto fetal membranes but was not intraamniotic. The low a-feto- protein early in pregnancy and the placental abruption most likely relate to an abnormal placentation Placental site trophoblastic tumours 5. Miscellaneous trophoblastic tumours These are rare and consist of exaggerated placental site and placental site nodule and plaque. Ultrasound finding in cases of PHM, includes a fetus (sometimes growth restricted), amniotic fluid and focal areas of anechogenic spaces in the. An ultrasound pelvis done at 9 weeks postpartum to determine the cause of persistent spotting (Fig. 1, 2), showed an endometrial thickness of 15 mm.There was also a heterogeneous focal area measuring 2.0 × 1.9 × 1.3 cm at the Caesarean section scar, which was thought to represent a hematoma, although small amounts of retained products of conception could not be excluded
Placental site nodule. H&E stain. Placental site nodule, abbreviated PSN, is a benign remnant of a placenta. It is seen on endometrial biopsies and hysterectomy specimens. Implantation site redirects here The positive stains include hPL,CD146, focal expression of hCG and negative for PLAP. Placental site nodule are benign lesions of intermediate trophoblast which is thought to represent incomplete involution of placental implantation site. Patient here can present as menorrhagia, intermenstrual bleeding or abnormal PAP This includes the benign placental site nodule and exaggerated placental site. Introduction. Hydatiform Moles. A molar pregnancy describes the fertilization event of a genetically non-viable ovum by sperm. The normal ovum and sperm both carry one-half of the genetic information required for a normal conception. On ultrasound, there will be. An intermediate trophoblast is a distinctive trophoblastic cell population from which four trophoblastic lesions are thought to arise: exaggerated placental site (EPS), placental site nodule (PSN), placental site trophoblastic tumor (PSTT), and epithelioid trophoblastic tumor (ETT) Transformation of a post-cesarean section placental site nodule into a coexisting epithelioid trophoblastic tumor and placental site trophoblastic tumor: a case report.

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. Common in reproductive age group (average age 30 - 32 years), typically after. Placental site trophoblastic tumor (PSTT) is a very rare variant of gestational trophoblastic tumor. It can occur after normal termination of pregnancy or spontaneous abortion and ectopic or molar pregnancy. There is a wide range of clinical manifestations from a benign condition to an aggressive disease with fatal outcome. One of the most important characteristics of PSTT, unlike other forms.
Predictably, the mature extravillous trophoblast will be more conspicuous in normal gestational tissues or in residual placental site nodules following pregnancy and less likely to be encountered in ETTs where the tumor is composed primarily of non-maturing malignant transitional (epithelioid) trophoblast A placental-site trophoblastic tumor is a rare neoplasia that is derived from the cells of the intermediate trophoblast. Morphological, biochemical, and Doppler ultrasound findings are presented regarding differential diagnosis using material from three recent cases. Essentially, placental-site trophoblastic tumors can be diagnosed if. Color Doppler ultrasound shows absence of flow in the main renal vein and reversal of diastolic flow in the main renal artery.

Mixed gestational trophoblastic neoplasms are extremely rare and comprise a group of fetal trophoblastic tumors including choriocarcinomas, epithelioid trophoblastic tumors, and placental site trophoblastic tumors. We present a case of a patient with extrauterine mixed gestational trophoblastic neoplasm adjacent to the abdominal wall cesarean scar Two distinct tumors of the intermediate trophoblast (placental site trophoblastic tumor and epithelioid trophoblastic tumor) are rare but frequently pose a diagnostic challenge when encountered.

Epithelioid trophoblastic tumor (ETT) is a rare gestational trophoblastic tumor. Cases of ETT present as abnormal vaginal bleeding in women of reproductive age, with low human chorionic gonadotropin (hCG) levels. ETT can be a sequela of any gestational event and can present in both intrauterine and extrauterine sites. Metastasis and death have been reported . these tumors start in the cells that would normally develop into the placenta during pregnancy. The term gestational ==> pregnancy. GTD begins in the layer of cells called the trophoblast that normally surrounds an embryo sions include exaggerated placental sites, placental site nodules (PSNs), PSTTs, and ETTs .

Gestational trophoblastic disease (GTD) describes a continuum of interrelated lesions that arise from abnormal proliferation of placental trophoblasts, ranging from benign hydatidiform mole to invasive mole, malignant choriocarcinoma (CCA), and placental site trophoblastic tumor (PSTT) ().Hydatidiform moles, both complete and partial, are benign lesions that resolve following uterine.
Placental abruption is when the placenta separates early from the uterus, in other words separates before childbirth.  It occurs most commonly around 25 weeks of pregnancy.  Symptoms may include vaginal bleeding, lower abdominal pain, and dangerously low blood pressure.  Complications for the mother can include disseminated intravascular coagulopathy and kidney failure. [2 Placental abruption is defined as premature placental separation from the implantation site. Placental abruption complicates approximately 1% of pregnancies and most frequently occurs between 24 to 26 weeks of gestation . Risk factors for abruption include chronic hypertension, trauma, and advanced maternal age Placental site nodule (PSN) Several studies had been conducted on toxemic pregnancies and its associated morbidities whereas analysis on GTD are relatively sparse owing to the reason of uncommon incidence in developed nations .(7,8) However in Tropical countries like India, the incidence is comparatively higher and becomes as an unique. Placental site nodule is an uncommon, benign, generally asymptomatic lesion of trophoblastic origin, which may often be detected several months to years after the tenancy from which it resulted. PSN usually presents as menorrhagia, intermenstrual bleeding or an abnormal pap smear Transvaginal ultrasound is safe in the presence of placenta praevia and is more accurate than transabdominal ultrasound in locating the placenta. In cases where the presenting part is engaged, we need to consider rescan to confirm the placental site and the decision regarding the mode of birth to be made accordingly

Ruminants comprise a large group of herbivores that include cattle, sheep, goats and deer. All of these animals, as described below, have cotyledonary placentae. Certain other animals, such as camels, while considered ruminants, but have diffuse placentae similar to what is seen in horses located over the necrotic nodule found at hysterectomy, suggesting that this was the site of origin. Additionally, the tumor extended to placenta and onto fetal membranes but was not intraamniotic. The low a-feto- protein early in pregnancy and the placental abruption most likely relate to an abnormal placentation This finding decrease its likelihood to be a GCC.
