INTRODUCTION: An epithelial trophoblastic tumor (ETT) is a kind of rare trophoblastic tumor that may have the correlation with a prior gestational event. Especially, the one that appears in the lung is extremely rare. CASE SUMMARY: Here, we present a 24-year-old female patient with the chief complain of vaginal bleeding for more than 1 month, who was found to have a large mass (7.5 × 4.5 cm) in the right lower lobe, and it was finally confirmed as lung ETT by postoperative pathology after a successful radical resection of the pulmonary lobe...

Background: Although the morphological features characteristic of products of conception specimens including molar pregnancies are well described, substantial histopathological similarities are observed between the different entities, especially in cases of early pregnancies. Furthermore, there are no current solid criteria that could predict cases with progression to persistent gestational trophoblastic disease. In this study, we aimed to determine the most specific histopathological and immunohistochemical features required for accurate diagnosis that can reliably predict the clinical behavior...

OBJECTIVES: Doppler ultrasonography can be used to assess neoangiogenesis, a characteristic feature of postmolar gestational trophoblastic neoplasia. However, there is limited information on whether uterine artery Doppler flow velocimetry parameters can predict gestational trophoblastic neoplasia following a complete hydatidiform mole. The purpose of this study was as follows: 1) to compare uterine blood flow before and after complete mole evacuation between women who developed postmolar gestational trophoblastic neoplasia and those who achieved spontaneous remission, 2) to assess the usefulness of uterine Doppler parameters as predictors of postmolar gestational trophoblastic neoplasia and to determine the best parameters and cutoff values for predicting postmolar gestational trophoblastic neoplasia...

OBJECTIVE: Epithelioid trophoblastic tumor is a rare gestational trophoblastic neoplasm usually presenting in women of reproductive age, with a history of a prior gestational event. Its presentation in postmenopausal women is extremely rare. Immunohistochemical staining is a helpful aid to distinguish epithelioid trophoblastic tumor from other gestational trophoblastic neoplasms. Correct diagnosis is crucial for clinical management that can vary according to the type of gestational trophoblastic neoplasm...

BACKGROUND: The use of obstetric ultrasound in the diagnosis of gestational trophoblastic disease (GTD) in high-income settings is well established, leading to prompt management and high survival rates. Evidence from low-income settings suggests ultrasound is essential in identifying complicated pregnancies, but with limited studies reviewing specific conditions including GTD. OBJECTIVE: The aim of this study is to review the role of ultrasound in diagnosis and management of GTD in a marginalized population on the Thailand-Myanmar border...

Objective. Gestational Trophoblastic Disease (GTD) management requires clear guidelines for diagnosis, treatment, and follow-up. Unequal management skills among practitioners, inadequate treatment, irregular surveillance, and drop-out are common in resource-limited settings and can lead to life-threatening complications and morbidities. To address these challenges, we implemented a GTD Management Program at the National Center for Reproductive Health in Rabat, Morocco. Methods and Program Description. In-depth review of management protocols was carried out, and concise guidelines were developed, with targeted training for physicians...

Herein, we report a rare case of an epithelioid trophoblastic tumor of the uterus with radiologic-pathologic correlation in a 56-year-old postmenopausal woman. On T2-weighted magnetic resonance (MR) imaging, the tumor appeared as a hypointense irregular mass compared with the surrounding myometrium of the uterine corpus and encircled the cavity of the lower uterine segment. On dynamic contrast-enhanced MR images, the tumor appeared as a hypovascular mass and an inhomogeneously hyperintense mass in the delayed phase...

Gestational trophoblastic disease spectrum ranges from benign hydatidiform mole to trophoblastic malignancy (placental site trophoblastic tumor and choriocarcinoma). Benign gestational trophoblastic disease occurs in women of reproductive age and is extremely rare in postmenopausal women. We describe a case of complete vesicular mole in a 55-year-old postmenopausal woman complaining of postmenopausal bleeding. To our knowledge, our case represents one of the rare descriptions in the world literature of a benign complete hydatidiform mole in a postmenopausal woman...

BACKGROUND: Hypomethylated cell-free DNA from senescent placental trophoblasts may be involved in the activation of the inflammatory cascade to initiate labor. OBJECTIVE: To determine the changes in cell-free DNA concentrations, the methylation ratio, and inflammatory markers between women in labor at term vs women without labor. STUDY DESIGN: In this prospective cohort study, eligible participants carried a nonanomalous singleton fetus. Women with major medical comorbidity, preterm labor, progesterone use, aneuploidy, infectious disease, vaginal bleeding, abdominal trauma, or invasive procedures during the pregnancy were excluded...

Placental mesenchymal dysplasia (PMD) is an uncommon vascular anomaly of the placenta characterized by placentomegaly with multicystic placental lesion on ultrasonography and mesenchymal stem villous hyperplasia on histopathology. Placental mesenchymal dysplasia should be considered in the differential diagnosis of cases of multicystic placental lesion such as molar pregnancy, chorioangioma, subchorionic hematoma, and spontaneous abortion with hydropic placental changes. However, lack of high-velocity signals inside the lesion and a normal karyotype favor a diagnosis of PMD...

The fatal infantile neuromuscular type is the most severe form of glycogen storage disease type IV. We report a case of a 22-day-old female neonate born at 34 weeks gestation with polyhyramnios, fetal hydrops, and severe hypotonia. Placental examination revealed numerous periodic acid schiff (PAS)-positive diastase-resistant polyglucosan bodies in the cytoplasm of extravillous trophoblast predominantly in the placental basal plate. Muscle biopsy and autopsy findings supported a diagnosis of neuromuscular-type glycogen storage disease IV with extensive involvement of skeletal muscle, heart, and liver...

Gestational trophoblastic neoplasia (GTN) is a spectrum of diseases including partial and complete hydatidiform moles, placental site trophoblastic tumor, and choriocarcinoma. One of the most important considerations is recognition of the possibility of GTN after molar pregnancy or even normal pregnancy. It is common practice to use chest x-ray for the detection of pulmonary metastasis. Computed tomography imaging of the lungs is ordered if lung lesions are noted on chest x-rays. However, understanding the limitations of chest x-rays is important for detecting smaller pulmonary lesions...

The Gestational Trophoblastic Disease includes an interrelated group of diseases originating from placental tissue, with distinct behaviors concerning local invasion and metastasis. The high sensitivity of the serial dosages of human chorionic gonadotrophin, combined with advances in chemotherapy treatment, have made gestational trophoblastic neoplasia curable, most often through chemotherapy. However, surgery remains of major importance in the management of patients with gestational trophoblastic disease, improving their prognosis...

Trophoblast cells are the first embryonic lineage to differentiate during human development, and are needed to sustain fetal life through their role in constructing a placenta. As the fetus grows, the trophoblast rapidly expands and further differentiates to produce an extravillous subtype that invades the maternal tissues. Some of the extravillous trophoblast cells find their way into the reproductive tract, and can be safely captured by noninvasive collection from the endocervical canal, similarly to a Pap smear...

The classification system for Gestational trophoblastic neoplasia (GTN) has proved a controversial topic for over 100years. Numerous systems simultaneously existed in different countries, with three main rival classifications gaining popularity, namely histological, anatomical and clinical prognostic systems. Until 2000, prior to the combination of the FIGO and WHO classifications, there was no worldwide consensus on the optimal classification system, largely due to a lack of high quality data proving the merit of one system over another...

OBJECTIVE: To determine the efficacy of chemotherapy after failed initial treatment in patients with high risk gestational trophoblastic neoplasia (GTN). METHODS: We performed a retrospective IRB-approved chart review of all patients with GTN seen at a single institution from 1985 to 2015, including all patients who failed initial treatment. We summarized clinical characteristics with descriptive statistics and estimated progression-free survival (PFS) and overall survival (OS) with the Kaplan-Meier method...

Background: Worldwide introduction of the FIGO 2000 scoring system has provided an effective means to stratify patients with gestational trophoblastic neoplasia (GTN) to single- or multi-agent chemotherapy. However, the system is quite elaborate with an extensive set of risk factors. In this study, we re-evaluate all prognostic risk factors involved in the FIGO 2000 scoring system and examine if simplification is feasible. Patients and methods: Between January 2003 and December 2012, 813 patients diagnosed with GTN were identified at the Trophoblastic Disease Centre in London and scored using the FIGO 2000...

A 35-year-old woman presented to our institution with tender, right knee swelling. Radiological and pathological work-up revealed metastatic osteosarcoma. Prior to the initiation of chemotherapy, she underwent a routine urine pregnancy test and was surprised with a positive result. Serum beta human chorionic gonadotropin (βhCG) levels were also consistently positive and rising. No gestational sac was seen at transvaginal ultrasound. The paraneoplastic ectopic secretion of βhCG has been well described in gestational trophoblastic and gonadal tumours but has very rarely been associated with other tumour types...
