Background: This case describes chronic anemia of a late preterm infant secondary to maternal-fetal hemorrhage and subsequent findings of maternal choriocarcinoma., Clinical Findings: This infant was born at 35 6/7 weeks gestational age via cesarean section for non-reassuring fetal heart tones. The mother presented with decreased fetal movement and the biophysical profile was 4/8. Following delivery, the infant did not require respiratory support, was vigorous with extreme pallor, and had a hemoglobin of less than 5 on cord gas., Primary Diagnosis: Chronic anemia secondary to fetomaternal hemorrhage., Interventions: The infant's initial hemoglobin was 2.4 and hematocrit was 8.1. The mother's Kleihauer-Betke test was elevated at 7%. The infant required a partial exchange transfusion following admission to the neonatal intensive care unit. Following the partial exchange transfusion, the infant began to experience increasing respiratory distress and required respiratory support. An echocardiogram showed severe persistent pulmonary hypertension of the neonate. The mother was subsequently diagnosed with choriocarcinoma., Outcomes: The infant fully recovered from chronic anemia and persistent pulmonary hypertension of the neonate and was discharged home with the mother. The infant required follow-up testing for choriocarcinoma outpatient., Practice Recommendations: Newborns diagnosed with early chronic anemia should be evaluated, the cause investigated, and appropriate treatment considered. If the cause of blood loss is unknown, a maternal Kleihauer-Betke test should be considered. In this case, a partial exchange transfusion was performed to avoid cardiovascular volume overload, but another course of treatment could include small aliquots of packed red blood cell transfusions., Competing Interests: The author declares no conflicts of interest., (Copyright © 2024 by The National Association of Neonatal Nurses.)

Background and Objectives: Choriocarcinoma is an aggressive oncological disease that manifests as trophoblast tissue proliferation. The vast majority of primary lesions affect the uterus, with primarily extrauterine lesions being a rarity. Choriocarcinoma with an ongoing pregnancy is extremely rare because fetuses usually do not survive the third trimester. Case Report : We present a case of heterotopic tubal choriocarcinoma coexisting with a viable intrauterine pregnancy. A 30-year-old, 39-week pregnant woman (gravida 2, para 2) came to our hospital complaining of acute upper abdominal pain. During routine prenatal screening in the first trimester, no pathological ultrasound findings were detected. Similar abdominal pain episodes had been recorded at 18, 27, and 32 weeks of gestation, when patient was hospitalized for examination and observation, but the cause of symptoms at that time of gestation remained unclear. The patient underwent an emergency caesarean section due to severe abdominal pain and fetal compromise. She delivered a live male infant. During the surgery, around 1000 mL of blood clots were evacuated, and the excision of the right fallopian tube and masses, as well as the control of significant blood loss was performed. Postoperative serum beta-hCG was elevated to 139 482 IU/L, while imaging studies showed no metastasis. The histological examination of the excised tissue samples confirmed a diagnosis of tubal choriocarcinoma. With a FIGO score of 8, the patient received three courses of the EP/EMA regimen. After more than a year, the patient showed no radiographic signs of distant metastasis and is now in complete remission. Conclusions: This case highlights the diagnostic complexity of such extremely rare scenarios. Even though such cases are rare, it demonstrates the necessity for improved diagnostic measures to enhance patient outcomes in similar clinical situations.

Background: Delayed postpartum hemorrhage is rare, with an incidence of 0.5% to 2.0% in all pregnancies. The most important causes are placental remnants, infections, and placental bed subinvolution. Postpartum choriocarcinoma, a highly malignant complication of pregnancy, is a rare condition that can be easily misdiagnosed as other common causes, such as gestational remnants, and delays the diagnosis., Methods: Four patients visited our clinic complaining of delayed postpartum hemorrhage, combined with respiratory and neurological symptoms in 2 cases. Two cases were confirmed by histopathological examination and in addition, medical history, elevated human chorionic gonadotropin (hCG) level, and imaging findings help confirm the diagnosis of delayed postpartum hemorrhage caused by postpartum choriocarcinoma in other cases. Individualized combination chemotherapies were prescribed. In the light of massive cerebral metastasis in case 2, intrathecal methotrexate injection combined with whole-brain radiotherapy was prescribed., Results: Due to the absence of routine monitoring of β-hCG following full-term delivery, there was widespread metastasis at the time of diagnosis. Three patients got complete remission and there is no sign of recurrence. One patient had relapse and widespread metastasis and died at home 6 months after the last chemotherapy., Conclusion: It is important to be aware of the possibility of choriocarcinoma in patients with delayed postpartum hemorrhage. Clinicians should improve the recognition of choriocarcinoma following full-term delivery, emphasize the monitoring of β-hCG, comprehensively analyze the general condition of patients, and conduct standardized and individualized chemotherapy protocols., Competing Interests: The authors have no conflicts of interest to disclose., (Copyright © 2024 the Author(s).

Introduction: Intraplacental choriocarcinoma is a gestational trophoblastic neoplasia located within the placenta. Due to the usual silent presentation, more than half of the cases are diagnosed incidentally. It has been demonstrated that this pathology is linked to feto-maternal hemorrhage (FMH), stillbirth, and intrauterine growth restriction. The aim of our review was to establish if there are recurrent signs that might lead to an early diagnosis and better management in cases complicated by FMH., Materials and Methods: We performed a systematic review of the literature from 2000 up to March 2023. The adopted research strategy included the following terms: (gestational choriocarcinoma obstetrics outcome) AND (intraplacental choriocarcinoma) AND (gestational choriocarcinoma). The MEDLINE (PubMed), Google Scholar, and Scopus databases were searched., Results: The research strategy identified 19 cases of FMH coexisting with intraplacental choriocarcinoma (IC), as described in 17 studies. The perinatal mortality rate was 36.8%. In eight cases, histological diagnosis of IC was made post-delivery. Metastatic lesions were found in 75% (6/8) of described cases. One case of maternal death has been described. Chemotherapy was necessary in seven cases. Sporadical prenatal ultrasound signs were described., Discussion: The diagnosis of IC is usually delayed, mostly due to aspecific symptoms and signs. Histological analysis of the placenta, when not routinely performed, should be performed when warning symptoms are encountered. The maternal prognosis was good, with a mortality rate of 5.5%. A fertility-sparing approach is always possible even in the presence of metastasis. Chemotherapy seems to be useful in cases of maternal and neonatal metastasis.

Purpose: Gestational trophoblastic disease (GTD) coexisting with a steadily progressing pregnancy is an extremely rare condition presented in the literature as a single case or case series of successful delivery. The purpose of this study was to describe five cases of GTD and present possible management strategies for such patients., Methods: Clinical data of five pregnancies with coexisting GTD were identified within the Almazov National Medical Research Centre from 2018 to 2021., Results: Three cases of multiple pregnancies with complete hydatidiform moles and two cases of singleton pregnancies with intraplacental choriocarcinoma and invasive hydatidiform moles were identified. Three pregnancies were prolonged and ended with preterm deliveries. Malignant transformation of the GTD accounted for 60% of the cases. The condition of newborns was based on the level of prematurity and functional immaturity, and in all cases, it was aggravated by anemia., Conclusion: GTD coexisting with progressing pregnancy is threatened by the risks of preterm delivery, miscarriage, hemorrhage, and disease progression and requires monitoring in a multidisciplinary clinic experienced in the management of patients with malignant tumors during pregnancy. In cases of prolonged pregnancy against the background of GTD, we suggest the following monitoring during pregnancy: pelvic, abdominal ultrasound/MRI (without contrast), prenatal invasive fetal karyotype testing in cases of singleton pregnancy, lung X-ray/CT with uterine shielding, weekly assessment of β -hCG levels, and dynamic monitoring of the fetus. The following postnatal monitoring should be performed: morphological examination of the placenta, weekly assessment of β -hCG levels up to normalization, then monthly assessment up to six months, and control of β -hCG level of the newborn., Competing Interests: The authors declare that they have no conflicts of interest., (Copyright © 2023 Elena Ulrikh et al.)

Rationale: The global prevalence of leprosy has decreased substantially, and cases of leprosy infection are extremely rare in China. In this report, we present a case of recurrent choriocarcinoma complicated by leprosy infection during chemotherapy., Patient Concerns: A 24-year-old Chinese woman (gravida 3, para 2) presented to a local hospital with vaginal bleeding. Her medical history included a previous diagnosis of hydatidiform mole., Diagnoses, Interventions and Outcomes: The patient was diagnosed with choriocarcinoma and received chemotherapy in 6 cycles. Shortly after the initial treatment was completed, the disease recurred twice with resistance to multiple chemotherapeutic agents. In her second recurrence of choriocarcinoma, she was diagnosed with leprosy with many cutaneous nodules throughout her entire body. The patient was administered chemical treatment for leprosy with the multidrug therapy regimen after being diagnosed. To prevent exacerbating the infection, no immunotherapy was utilized to treat cancer, and the infection was well-controlled at the conclusion of anticancer therapy., Lessons: Because of immunological reduction, cancer patients are susceptible to a variety of infections. For patients with cancer, prevention and early detection of rare infectious diseases should receive special attention. Immunotherapy must be used with caution when treating patients with cancer and infections., Competing Interests: The authors have no conflicts of interest to disclose., (Copyright © 2023 the Author(s).

Background: Pure testicular choriocarcinoma is a rare type of non-seminomatous germ cell tumor extremely poor prognostic with the tendency to bleed at the metastatic site. At the time of the diagnosis, 70% of patients have metastatic lesions. Depending on the site of the metastasis, symptoms vary. Gastrointestinal involvement is seen in less than 5% of cases, mostly in the duodenum., Case Presentation: We present a 47 years old male with testicular choriocarcinoma involving the jejunum, lung, liver, and kidney presenting with acute abdominal pain, melena, and dyspnea with some paraneoplastic symptoms. The patient had increased, severe and constant pain in the right lower quadrant for the previous four days. Additionally, he was complaining of nausea, vomiting, anorexia, and a history of melena for the last 10 days. Dyspnea on exertion, hemoptysis, and dry cough were the symptoms he was suffering from, for almost one year. The patient's general appearance was pale, ill, and thin with 10 kg of weight loss during the last some months. The computed tomography (CT) scan reported multiple metastatic lesions in both liver lobes and the left kidney. Pathologic study of the samples of small bowel lesions showed metastatic choriocarcinoma. Following the patient had been referred to an oncologist to start the chemotherapy regime. Finally, the patient has expired after 40 days of his first admission., Conclusions: Testicular choriocarcinoma is a rare but fatal malignancy among young men. Gastrointestinal metastases are infrequent involvement represented by melena and acute abdominal pain, obstruction, and mass. Physicians should consider it as a differential diagnosis for acute abdomen and gastrointestinal bleeding causation., (© 2023. The Author(s).)

Fetomaternal hemorrhage (FMH) is a known cause of neonatal anemia due to fetal blood loss to the maternal circulation, occurring when the maternal-fetal barrier is disrupted. Several causes must be considered, although in most cases the etiology remains unknown. Intraplacental choriocarcinoma (ICC) is a rare entity and has been related with massive FMH, intrauterine fetal demise, severe neonatal anemia and metastatic choriocarcinoma in both mother and infant. There are 25 cases of histopathologically confirmed ICC complicated with FMH described in the literature. Because FMH occurs unexpectedly and the majority of patients with ICC are asymptomatic, this diagnosis may be missed. Once FMH is confirmed, underlying malignancy should be kept in mind. The authors present a case report of severe neonatal anemia following FMH related to ICC and highlight the importance of serum β-hCG monitoring in cases of massive FMH.

Background: Testicular tumor is one of the common solid tumors in young men. Testicular choriocarcinoma is a non-spermatogonial germ cell tumor, which is the rarest of all testicular cancers. Choriocarcinoma usually shows bleeding at the metastatic site, while gastrointestinal involvement is rare., Methods: Here, we report a case of testicular choriocarcinoma with gastrointestinal bleeding as the first diagnosis and summarize the similar cases all over the world in recent 20 years., Results: A 28-year-old male was treated with repeated melena for 2 months. No bleeding foci of the stomach, duodenum, colon, and rectum were found in endoscopy, and no bleeding foci of digestive tract was found in selective angiography, but a space occupying lesions of the lung, liver, and upper jejunum were found in chest and abdominal CT. Considering the possibility of a metastatic tumor and the ineffectiveness of medical treatment, the patient was converted to surgical treatment. The postoperative pathology was consistent with testicular choriocarcinoma. The patient received a chemotherapy regimen of paclitaxel, ifosfamide, and cisplatin. At present, the chemotherapy regimen is well tolerated., Conclusions: The case report confirmed that even if we cannot find the logical relationship between clinical manifestations and genital examination, genital examination should also be part of the patient's systematic examination., (© 2022.

Background: Extragonadal choriocarcinoma is rare and can be associated with hyperthyroidism when producing very high levels of human chorionic gonadotropin., Case Presentation: A 62-year-old Hispanic female presented with a 3-week history of shortness of breath, palpitations, extreme weakness, new-onset hot flashes, and right flank pain. Her physical examination was remarkable for tachycardia, hepatomegaly, hyperreflexia, and tremor; goiter was absent. Laboratory studies revealed increased lactate dehydrogenase, alkaline phosphatase, suppressed thyroid stimulating hormone, very elevated T4, and absent thyroid stimulating immunoglobulin. 18 F-fluorodeoxyglucose positron emission tomography-computed tomography exhibited hepatomegaly with multiple large fluorodeoxyglucose-avid liver masses and a focus of fluorodeoxyglucose avidity in the stomach with no structural correlate. A thyroid scan ( 99m TcO 4 - ) showed diffusely increased tracer uptake. She was started on propranolol and methimazole. Upon stabilization of severe thyrotoxicosis, upper endoscopy was performed, showing a ~ 5 cm bleeding lesion in the greater stomach curvature body; biopsy was consistent with choriocarcinoma; beta-human chorionic gonadotropin hormone was 2,408,171 mIU/mL. The patient received methotrexate followed by etoposide and cisplatin. Methimazole was titrated down, and upon liver failure the medication was stopped. The thyrotoxicosis was effectively controlled with antithyroid drug and concurrent chemotherapy. At ~ 1.5 months after initial diagnosis, the patient died due to bleeding/acute liver failure with coagulation defects followed by multiple organ failure., Conclusions: Severe thyrotoxicosis can represent an unusual initial presentation of metastatic choriocarcinoma in the setting of extreme elevation of beta-human chorionic gonadotropin. Primary gastric choriocarcinoma is an aggressive malignancy with very poor outcomes. The co-occurrence of severe thyrotoxicosis with advanced primary gastric choriocarcinoma and imminent liver failure complicates management options., (© 2022. The Author(s).)

A 27-year-old man newly diagnosed with metastatic testicular choriocarcinoma developed a large right perinephric haematoma secondary to a metastatic deposit in his right kidney. His presentation was also complicated by bilateral iliac venous thrombosis and pulmonary embolism identified prior to initiation of chemotherapy. He underwent multiple attempts at angioembolisation of the bleeding vessels and ultimately angioembolisation of the main renal artery had to be performed to control the bleeding. Following resolution and commencement of chemotherapy, the patient also developed spontaneous intracranial haemorrhage requiring craniotomy., Competing Interests: Competing interests: None declared., (© BMJ Publishing Group Limited 2022.

Uterine choriocarcinoma is a trophoblastic neoplasm most commonly related to pregnancy. However, there are already cases of non-gestational uterine choriocarcinoma (NGC) described in literature. The difficult diagnosis may delay treatment and threaten patient survival. We report the case of a 37-year-old patient presenting with abnormal haemorrhage and moderate levels of beta-human chorionic gonadotropin (β-hCG). As imaging exams did not show any suspicious site for the origin, choriocarcinoma was not considered so the treatment was delayed. Anatomopathological diagnosis was given both from the surgical sample of hysterectomy and from a skin lesion. The lesion was discovered inside a myoma. At this point, β-hCG levels were substantially high and she presented with respiratory distress due to pulmonary metastasis. The patient was transferred to an intensive care unit and underwent mechanical ventilation as well as life-saving chemotherapy. At 10 months after diagnosis, she is well and in remission. The delay from not suspecting the diagnosis was almost fatal for the patient., Competing Interests: Competing interests: None declared., (© BMJ Publishing Group Limited 2022. No commercial re-use.

Gestational choriocarcinoma is a malignant tumour originating from the trophoblastic tissue that can arise during or after any type of pregnancy, but most of the time follows a molar pregnancy. Characteristic for this tumour is its rapid haematogenous spread to various organs, causing atypical presentations often attributable to metastatic disease. We review three cases that occurred during and shortly after a coexistent intrauterine pregnancy. The patient of Case 1 presented with neurological symptoms due to hypercalcaemia, in Case 2 there was initially suspicion of appendicitis and the third patient presented with acute respiratory insufficiency. This case series illustrates that, although highly effective chemotherapy is available, choriocarcinoma can be life-threatening and accurate diagnosis is challenging but critical., Competing Interests: Competing interests: None declared., (© BMJ Publishing Group Limited 2021.

Choriocarcinoma is an aggressive malignant trophoblastic neoplasm. The rapid growth of neoplastic tissue and myometrial invasion can cause uterine perforation. It is important to quickly diagnose the disease and plan treatment because these tumors are nearly always curable, and fertility can be preserved in most cases with proper management. The outbreak of novel coronavirus disease has affected the whole world since January 2019 and caused delays in treatment and follow-up of patients all over the world. In this study, we report a case of choriocarcinoma who postponed her admission to the hospital after diagnosis because she was afraid of the pandemic and lost her fertility due to uterine rupture and massive intra-abdominal hemorrhage.

Rationale: Choriocarcinoma is a highly aggressive tumor. It occurs infrequently during pregnancy. The management of choriocarcinoma during pregnancy poses several challenges., Patient Concerns: At 34 weeks of gestation, a 21-year-old primigravida was transferred to the emergency room for cephalgia, reduced fetal movements, and left intra-atrial intracavitary thrombus., Diagnosis: Choriocarcinoma in the third trimester with lung and brain metastases, pulmonary vein thrombosis (PVT), and systemic thrombosis., Intervention: An emergency cesarean section was performed. Subsequently, low-molecular-weight heparin anticoagulation combined with multiagent chemotherapy was administered., Outcome: A 1.59 kg live female was born. Multiagent chemotherapy combined with anticoagulation led to complete regression of the cerebral and pulmonary lesions and the dissolution of pulmonary vein thrombus. At the 11-month follow-up, the patient remained in complete remission without complications, and her child was disease-free., Lessons: This is the first case of gestational choriocarcinoma with PVT. Our case suggests that conservative therapy can be the first choice for small, asymptomatic PVT secondary to choriocarcinoma., Competing Interests: The authors have no funding and conflicts of interests to disclose., (Copyright © 2021 the Author(s).

Neoplastic cerebral aneurysms (NCAs) are highly rare lesions characterized by invasion of cancerous cells within the wall of an artery leading to aneurysm formation. While NCAs caused by myxomas are well characterized in the clinical literature, rarer etiologies have also been reported and are typically associated worse clinical outcomes. We performed the first PRISMA-compliant systematic literature review of true, non-myxoma neoplastic cerebral aneurysms using the PubMed/MEDLINE, Embase, Scopus, and Google Scholar databases. Data of interest included age, sex, aneurysm size, number of aneurysms, aneurysm location, neoplasm type, aneurysm treatments, cancer treatments, risk of rupture, intracerebral hemorrhage prevalence, subarachnoid hemorrhage prevalence, and survival at 90 and 180 days. A total of 50 studies met our inclusion criteria. The mean age of the patient population was 37.4 years (SD: ±16.8) and had an overall female preponderance (39/50, 78%). Of these NCA cases, 29/50 (58.0%) were choriocarcinomas, 10/50 (20.0%) were related to lung cancer, and 11/50 (22.0%) had other origins of variable pathologies. 90-day survival rates were 60.0% (15/25) for choriocarcinomas, 28.6% (2/7) for the lung cancer group, and 14.3% (1/7) for the other origins group. 180-day survival rates were 52.0% (13/25) for the choriocarcinoma group, 14.3% (1/7) for the lung cancer group, and 0% (0/7) for the other origins group. Prognosis of NCA patients ultimately depends on the course of disease progression and cancer management. Further research is needed to better understand optimal treatment modalities for patients with NCAs., Competing Interests: Declaration of Competing Interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2020 Elsevier Ltd.

Background: 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. On the basis of a literature review, this type of case has never been reported before due to the unique lesion location and low incidence., Case Presentation: Our patient was a 39-year-old Chinese woman who had a history of two cesarean sections and one miscarriage. She had a recurrent anterior abdominal wall mass around her cesarean scar, and the mass was initially suspected of being choriocarcinoma of unknown origin. The patient had concomitant negative or mildly increased serum β-human chorionic gonadotropin at follow-up and no abnormal vaginal bleeding or abdominal pain. However, she underwent local excision twice and had two courses of chemotherapy with an etoposide and cisplatin regimen. She finally opted for exploratory laparotomy with abdominal wall lesion removal, subtotal hysterectomy, bilateral salpingectomy, and left ovarian cyst resection, which showed the abdominal wall lesion, whose components were revealed by microscopy and immunohistochemical staining to be approximately 90% epithelioid trophoblastic tumors and 10% choriocarcinomas from a solely extrauterine mixed gestational trophoblastic neoplasm around an abdominal wall cesarean scar., Conclusions: It is worth noting whether epithelioid trophoblastic tumor exists in the setting of persistent positive low-level β-human chorionic gonadotropin. More studies are required to provide mechanistic insights into these mixed gestational trophoblastic neoplasms.

Nongestational ovarian choriocarcinoma (NGOC) accounts for <1% of ovarian germ cell tumors and may develop into the rare and fatal complication of choriocarcinoma syndrome. We reported a case of a 12-year-old girl with NGOC that metastasized to the lungs, retroperitoneal lymph nodes and brain. On day 2 of chemotherapy with actinomycin D and etoposide, choriocarcinoma syndrome developed due to a massive pulmonary hemorrhage, presenting as acute respiratory distress syndrome. The patient received mechanical ventilation and multimodal support and completed two cycles of an actinomycin D and etoposide regimen with intubation. After the patient's acute respiratory distress syndrome was under control, she received 9 cycles of more intensive chemotherapy regimens and achieved complete remission. An exploratory laparotomy with salpingo-oophorectomy confirmed ovarian choriocarcinoma. The patient remained disease-free at a 3-month follow-up visit. In conclusion, appropriate management consisting of multimodal support and timely, sequential and intensive chemotherapy is effective for NGOC complicated with choriocarcinoma syndrome. Stating with mild regimens would probably reduce the risk of choriocarcinoma syndrome, or at least lessen its severity. To our knowledge, we presented the first report of NGOC-related choriocarcinoma syndrome., (Copyright © 2020. Published by Elsevier Inc.)

Objective: To investigate the demographics, natural history and treatment outcomes of non-molar gestational choriocarcinoma., Design: A retrospective national population-based study., Setting: UK 1995-2015., Population: A total of 234 women with a diagnosis of gestational choriocarcinoma, in the absence of a prior molar pregnancy, managed at the UKs two gestational trophoblast centres in London and Sheffield., Methods: Retrospective review of the patient's demographic and clinical data. Comparison with contemporary UK birth and pregnancy statistics., Main Outcomes: Incidence statistics for non-molar choriocarcinoma across the maternal age groups. Cure rates for patients by FIGO prognostic score group., Results: Over the 21-year study period, there were 234 cases of non-molar gestational choriocarcinoma, giving an incidence of 1:66 775 relative to live births and 1:84 226 to viable pregnancies. For women aged under 20, the incidence relative to viable pregnancies was 1:223 494, for ages 30-34, 1:80 227, and for ages 40-45, 1:41 718. Treatment outcomes indicated an overall 94.4% cure rate. Divided by FIGO prognostic groups, the cure rates were low-risk group 100%, high-risk group 96% and ultra-high-risk group 80.5%., Conclusions: Non-molar gestational choriocarcinoma is a very rare diagnosis with little prior detailed information on the demographics and natural history. The data in this study give age-related incidence data based on a large national population study. The results also demonstrated the widely varying natural history of this rare malignancy and the marked correlation of disease incidence with rising maternal age., Tweetable Abstract: National gestational choriocarcinoma database indicates a close association between increasing maternal age and incidence., (© 2020 Royal College of Obstetricians and Gynaecologists.)

The respiratory syncytial virus (RSV) is the main pathogen associated with upper respiratory tract infections during early childhood. Vertical transmission of this virus has been suggested in humans, based on observations recorded during animal studies that revealed an association of RSV with persistent structural and functional changes in the developing lungs of the offspring. However, human placentas have not yet been evaluated for susceptibility to RSV infection. In this study, we examined the capacity of RSV to infect a human trophoblast model, the BeWo cell line. Our results suggest that BeWo cells are susceptible to RSV infection since they allow RNA viral replication, viral protein translation, leading to the production of infectious RSV particles. In this report, we demonstrate that a human placenta model system, consisting of BeWo cells, is permissive to RSV infection. Thus, the BeWo cell line may represent a useful model for studies that aim to characterize the events of a possible RSV infection at the human maternal-fetal interface.

Background: Gestational trophoblastic neoplasia rarely occurs in term pregnancies. Stage IV choriocarcinoma treated with conventional chemotherapy can result in death as a result of hemorrhagic sequelae at tumor sites., Case: A 30-year-old woman at 34 weeks of gestation presented with a persistent cough, worsening dyspnea, and vaginal bleeding. Chest radiograph demonstrated innumerable lung nodules, and quantitative β-hcg concentration exceeded 1.3 million milli-international units/mL. Cesarean delivery was performed for presumed abruption. Placental pathology demonstrated choriocarcinoma, and imaging confirmed stage IV disease with a World Health Organization score of 14. Remission was achieved after two courses of low-dose induction chemotherapy followed by 10 cycles of combination chemotherapy., Conclusion: Gestational trophoblastic neoplasia should be considered in a pregnant or postpartum woman presenting with atypical vaginal bleeding. Coexistent pulmonary or neurologic findings may suggest advanced disease.

Rationale: Brain metastasis of choriocarcinoma is a highly malignant gestational trophoblastic neoplasia (GTN) and has a notoriously poor prognosis. Hemorrhagic choriocarcinoma lesions may lead to life-threatening conditions also. Treatment of brain metastases of choriocarcinoma with hemorrhage in multiple sites is very difficult in clinical practices. A patient has been successfully treated in our hospital, which provides as clinical references for this difficulty in treating brain metastases of choriocarcinoma with hemorrhage in multiple sites., Patient Concerns: A 28-year-old patient with gravida 2, para 0 was admitted in our hospital for amenorrhea, vaginal bleeding, and lower abdominal pain., Diagnoses: The patient was diagnosed as choriocarcinoma FIGO stage IV and the score of the Prognostic Scoring Index modified by the WHO was 15., Interventions: The patient received multiagent chemotherapy (EMACO regimen) soon after the diagnosis of choriocarcinoma with brain metastasis. During the therapy, the patient was given 3 different methods of treatment for metastatic site hemorrhage. An emergency surgery was performed to control massive bleeding from the metastatic lesions of broad ligament. Blood transfusions were given to treat acute left pulmonary hemorrhage. Uterine artery embolization (UAE) was performed to treat increased uterine bleeding., Outcomes: The patient achieved remission after 9 cycles of chemotherapy. She has been followed up for 14 months with no signs of tumor recurrence., Lessons: The diagnosis of choriocarcinoma may be difficult, especially in the setting with the limit of medical resources. The application of various diagnostic techniques such as x-ray, computed tomography, and magnetic resonance imaging is helpful for evaluating the patient's condition.

Rationale: Near-term intraplacental choriocarcinoma (IC) coexisting with massive fetomaternal hemorrhage (FMH) is rare, and its clinical course is poorly understood. Here, we report a new case from our hospital, with detailed discussion and literature review., Patient Concerns: A 21-year-old Chinese female at 35 weeks gestation was admitted to our hospital due to reduced fetal movement. Near-term IC coexisting with massive FMH was diagnosed after delivery., Intervention: The mother and infant were followed 3 months after delivery. Beta-human chorionic gonadotropin (β-HCG), pathological examination of the placenta, and computed tomography scans were performed for the mother and β-HCG was performed for the infant., Outcomes: The mother's β-HCG serum level increased from 31,280 IU/L (6 days postdelivery) to 192,070 IU/L (49 days postdelivery), and then steadily fell to 42,468 IU/L (3 months postdelivery) without chemotherapy. The mother died from metastasis and cerebral hemorrhage. The infant survived and his β-HCG serum level fell to within the normal range without chemotherapy., Lessons: FMH associated with near-term IC is a rare disease. Measurement of maternal β-HCG may therefore represent a useful parameter when IC is a possible differential diagnosis. A pathological examination of the placenta should be performed in all cases of FMH to better identify cases of IC. Future research should aim to develop methods of identifying which patients with IC should receive chemotherapy, whether we should use single- or multiagent chemotherapies, and whether there is a positive correlation between chemotherapy regimen and β-HCG serum levels.

Background: Choriocarcinoma coexisting with or after normal pregnancy is extremely rare. To our knowledge, our case report is the first time cerebral mycotic pseudoaneurysms from choriocarcinoma have been proven angiographically., Case Description: A 38-week pregnant 26-year-old woman presented with an acute left frontal hemorrhage. She underwent emergency cesarean section, followed by hematoma evacuation and resection of what grossly appeared to be a medium-sized arteriovenous malformation at the time of surgery. Angiogram before and after resection showed no obvious vascular pathology. One month later, she returned with status epilepticus, and an acute parenchymal hematoma posterior to the surgical resection cavity was identified. Angiography showed a multilobulated pseudoaneurysm along the left middle cerebral artery. This was resected and found on histopathology to have choriocarcinoma within and around the blood vessels. Serum human chorionic gonadotrophin levels increased daily. Pan computed tomography showed a left lung lobular mass. The diagnosis was stage 4 World Health Organization score 9 high-risk metastatic choriocarcinoma requiring radiation followed by multiagent chemotherapy. Two weeks later, she had another seizure. An angiogram showed an unruptured pseudoaneurysm along the right posterior cerebral artery, which was embolized., Conclusions: Metastatic choriocarcinoma is rarely considered during a viable pregnancy but is almost always fatal if unrecognized. Early recognition enhances the chances of cure with chemotherapy. Arteriovenous malformations are typically considered in young women with intracerebral hemorrhages and have higher risk of rupture in pregnant women, but physicians should also be aware of metastatic choriocarcinoma and the development of mycotic aneurysms in peripartum women with intracerebral hemorrhages., (Published by Elsevier Inc.)

Gestational trophoblastic diseases (GTD) correspond to several entities which all have a common pattern: hypersecretion of human chorionic gondotrophin by trophoblastic hyperplasia. Between 2010 and 2012, there were 4 maternal deaths due to GTD (choriocarcinoma). The ratio of maternal death caused by GTD was 0,16/100,000 living births which was similar to the rate from the 2007-2009 period. These deaths represented 1.6% from the whole maternal mortality and 3.3% of the direct maternal mortality. These four deaths occurred after delivery and the diagnosis of GTD was made between 60 and 180 days in the postpartum period. Two cases seemed to be potentially avoidable. The main causes of suboptimal management were linked to delay either in diagnosis of GTD or in initiating the appropriate treatment. The analysis of these maternal deaths gave the opportunity to stress some major lessons to optimize medical management of GTD. Therefore, a patient presenting with persistent bleedings more than six weeks after delivery needs some specific exams such as plasma human chorionic gondotrophin measurement and histopathologic examination to affirm GTD and start early specific treatments generally leading to complete recovery., (Copyright © 2017 Elsevier Masson SAS.

Primary mediastinal choriocarcinoma in male is not a very common disease, with nonspecific clinical manifestations. Gynecomastia and testicular atrophy are present in some cases. The levels of serum human chorionic gonadotropin are often significantly increased. Giant lump in the mediastinum and bilateral lungs multiple metastases can be seen on the computed tomography for lung. The diagnosis for it depends on pathological biopsy. Current treatment method is a comprehensive, consisting of chemotherapy, radiotherapy and surgery. This paper reported a case of primary mediastinal choriocarcinoma in male, who were diagnosed and treated in the Second Xiangya Hospital of Central South University. He was admitted for cough and hemoptysis, and finally diagnosed by biopsy. The prognosis is very poor. Therefore, it is important to take physical examination regularly because it can be detected and diagnosed early.

Liver fluke infections occur in people worldwide. In some low-income regions, a combination of ecological, agricultural, and culinary factors leads to a very high prevalence of infection but, in higher-income regions, infections are uncommon. Infection is associated with substantial morbidity and several liver fluke species are recognised as biological carcinogens. Here, we review the epidemiology, clinical significance, and diagnostic and treatment strategies of human infection with these pathogens., (Copyright © 2017 Elsevier Ltd. All rights reserved.)

Rationale: Choriocarcinoma accompanied with pulmonary embolism (PE) is rare and difficult to diagnose and treat. There are about 25 cases reported in literature, which presented variable clinical characteristics and prognosis., Patient Concerns: We reported a case of choriocarcinoma presenting PE as the first manifestation in a 26-year-old Chinese female., Diagnoses: Four months before her admission to our hospital, she presented to a local hospital with respiratory manifestations, and was first diagnosed as bronchitis and treated with antibiotics without improvement, and subsequently suspected of having pulmonary tuberculosis and receive anti-tuberculosis therapy, with no response. Upon admission to our hospital, spiral computed tomography-pulmonary angiography revealed complete occlusion of right pulmonary artery, leading to PE. She received thrombolysis and anticoagulant therapy, without improvement. Further interrogation of the patient revealed a history of irregular vaginal bleeding and multiple pregnancies and abortions. Following the laboratory report of a significantly elevated level of serum beta-human chorionic gonadotropin (β-HCG) combined with other clinical and laboratory findings, a diagnosis of choriocarcinoma accompanied with PE was established based on the criteria formulated by the International Federation of Gynecology and Obstetrics and guideline of European Society for Medical Oncology., Interventions: With 1 cycle of chemotherapy with etoposide-methotrexateactinomycin D-cyclophosphamide-vincristine (EMA-CO), her dyspnea and other symptoms improved, with a significant decrease in the serum β-HCG level and pulmonary artery pressure., Outcomes: Unfortunately, she showed bone marrow inhibition, could not continue further chemotherapy, and finally died after discharging. We reviewed 25 similar cases in the literature, and found that all 17 cases receiving chemotherapy showed complete recovery while 6 of 8 cases without chemotherapy died during hospitalization., Lessons: This case report illustrates the challenges in diagnosis of choriocarcinoma presenting with respiratory manifestations, and highlights the importance of early diagnosis and timely appropriate chemotherapy in management of this disease.

Extrauterine choriocarcinoma in the fallopian tube is very rare and is often diagnosed and treated as an ectopic tubal pregnancy. A 34-year-old woman who initially became pregnant after infertility treatment using ovulation induction with clomiphene citrate and intrauterine insemination was later diagnosed with an extrauterine choriocarcinoma in the left fallopian tube. Because of suspected left ectopic tubal pregnancy based on ultrasonography findings and a high level of β-human chorionic gonadotropin (β-hCG; 7054.3 mIU/mL), the patient underwent diagnostic laparoscopy at a gestational age of 6 weeks. Left salpingectomy was performed based on the operative diagnosis of an ectopic tubal pregnancy. No signs of tubal rupture or leakage of contents from the fallopian tube were observed during the operation. Her serum β-hCG dropped to 10.3 mIU/mL at 15 days postoperatively. Histopathology demonstrated an extrauterine choriocarcinoma in the removed fallopian tube, and the patient was referred to a regional oncologic hospital to receive additional adjuvant chemotherapy. This case indicates that conservative treatment for ectopic pregnancy should be chosen carefully, and that histopathology diagnosis and appropriate β-hCG monitoring following treatment are important not only to diagnose persistent ectopic pregnancy, but also to rule out the possibility of a tubal choriocarcinoma., (Copyright © 2017 AAGL.

Background: Gestational choriocarcinoma is the most common gestational trophoblastic neoplasia; it is often secondary to hydatidiform mole, as well as to abortion, ectopic pregnancy, premature delivery, or term delivery. Approximately 60% of patients with choriocarcinoma develop pulmonary metastases, but for patients with a respiratory condition, choriocarcinoma with lung metastasis is a relatively rare lung cancer diagnosis. Three cases of choriocarcinoma with pulmonary metastasis who had the primary symptom of hemoptysis are described., Case Presentation: This case report describes a 35-year-old Chinese woman of Han nationality, a 23-year-old Chinese woman of Han nationality, and a 46-year-old Chinese woman of Han nationality whose primary symptom was hemoptysis and different chest imaging manifestations; they were finally diagnosed as having pulmonary metastatic choriocarcinoma. All patients had low risk factors, including abortion, hydatidiform mole, and ectopic pregnancy. Human chorionic gonadotropin played an important role in choriocarcinoma diagnosis., Conclusions: Based on the diagnosis and treatment of the three patients, we suggested that for women with pregnancy history and hemoptysis (particularly in the presence of risk factors such as abortion, hydatidiform mole, ectopic pregnancy, and >35-years old), choriocarcinoma may be the possible diagnosis or at least the main differential diagnosis.

Choriocarcinoma (CC) is a highly malignant tumor originating in the trophoblastic tissue. The clinical presentation of CC is so much varied that every case may be one of its kinds and thus can be a diagnostic challenge. Numerous case reports have been published in various journals regarding the unusual clinical presentations of this cancer. Therefore, we conducted a systematic review of all case reports in English language on gestational CC published in PubMed-indexed journals from 1998 to 2015. The main aim was to provide a summary and critical analysis of all the data and evidence published regarding the atypical clinical presentations of CC in recent years. In total, 121 case reports pertaining to unusual clinical manifestations of gestational CC were analyzed. The age of patients in whom cases were reported ranged from 17 to 67 years, and the time period between the index pregnancy and development of CC varied from 4 weeks to as long as 25 years. Cardiopulmonary complaints (20.66%) followed by gastrointestinal (18.43%) and central nervous system manifestations (17.67%) were found to be the most common. Through this review, the authors have made an attempt to discuss various manifestations with which a patient with gestational CC can present to clinician so that early diagnosis and timely management can be initiated, thus improving clinical prognosis., (Copyright © 2017 Taiwan Association of Obstetrics & Gynecology.

A 22-year-old woman with a 1-month history of shortness of breath that was treated as a case of tuberculosis and pulmonary embolism was referred to the authors' hospital. Because of the hemodynamic instability in this patient, venoarterial extracorporeal membrane oxygenation (ECMO) was administered in the intensive care unit. She underwent a pulmonary embolectomy for the treatment of progressive circulatory collapse secondary to a pulmonary embolism. The histopathologic result was consistent with a metastatic choriocarcinoma. Despite the surgical management, persistent refractory cardiogenic shock occurred. Subsequently, the patient was treated with chemotherapy in the presence of ECMO and responded well to chemotherapy. She was discharged after 3 months. This case suggests that metastatic choriocarcinoma should be considered as a differential diagnosis in women of childbearing age presenting with a pulmonary embolism, and ECMO may be beneficial in patients with pulmonary embolism for bridging to surgical embolectomy and chemotherapy., Competing Interests: relevant to this article was not reported.

A wild-born, captive-reared, 14 yr old, primiparous female California sea lion Zalophus californianus presented for anorexia of 14 d duration and abdominal distention. Routine complete blood cell count revealed leukocytosis with a neutrophilia, and serum chemistry revealed hypoalbumenemia and hyponatremia. Treatment with broad spectrum antibiotics and non-steroidal anti-inflammatories were started, but the animal continued to decline. Abdominal radiographs revealed a mature mineralized fetal skull and spine in the caudal abdomen and abdominal ultrasound revealed ascites but could not confirm the fetus. The patient was taken to surgery where a full term fetus was found outside of the uterus but within the fetal membranes, representing a secondary ectopic pregnancy. The patient passed away during surgery and was taken to necropsy. Gross necropsy revealed a diffuse peritonitis with yellow deposits over the serosal surfaces of the abdominal organs. The uterus appeared intact grossly and the ovaries appeared abnormal. The mesenteric, renal, and sub-lumbar nodes were enlarged and edematous. Histopathology revealed choriocarcinoma in the right uterine horn with evidence of chronic uterine rupture and protrusion of the placental tissue into the abdomen. The choriocarcinoma had metastasized locally as well as to the liver, spleen and lung. Choriocarcinoma is a highly malignant trophoblastic neoplasm that is rare in domestic animals. This case represents, to the authors' knowledge, the first report of gestational choriocarcinoma causing secondary ectopic pregnancy in a California sea lion and presents questions regarding pregnancy monitoring and management in a population of captive, minimally trained California sea lions.

Objective: Term pregnancy with choriocarcinoma is a rare condition that can be a serious health threat to both the mother and the fetus. We present a rare case of term pregnancy with choriocarcinoma presenting as severe fetal anemia and postpartum hemorrhage., Case Report: A 34-year-old woman, gravida 3 para 2, was admitted for profuse vaginal bleeding 2 weeks after cesarean delivery of a full-term anemic baby. Transvaginal sonography revealed a 4.7-cm×10.6-cm heterogenous lesion in the endometrial cavity. Dilatation and curettage was done and a pathologic report revealed choriocarcinoma. Metastatic workup showed lung metastasis. The patient achieved remission after eight cycles of chemotherapy in the form of etoposide, methotrexate, actinomycin D, cyclophosphamide, and vincristine. There was no evidence of recurrence in the subsequent 3 years of regular follow up., Conclusion: Although fetomaternal hemorrhage is a rare form of presentation of choriocarcinoma, its presence should alert the physician to investigate the cause further. This chemotherapy regimen was effective in our case and the patient needed to be followed up carefully., (Copyright © 2016. Published by Elsevier B.V.)

Purpose of Review: This article aims not only to review recent literature about the clinical features of massive fetomaternal hemorrhage (FMH) and identification of risk factors, but also to alert obstetricians and pediatricians to this underdiagnosed and underestimated severe obstetrical issue. In addition, a simplified flow chart for the antenatal management of suspected FMH is proposed., Recent Findings: Improvements in obstetrical and neonatal care have decreased perinatal morbidity and mortality and the rate of stillbirth. Unfortunately, because of the nonspecific signs on presentation, adverse outcome associated with massive FMH has not followed this trend and still has devastating consequences. As even the definition varies among publications and there is lack of universal screening, the real nature still remains obscure. Improvements in the diagnosis of fetal anemia, laboratory and intrauterine transfusion techniques, and the implementation of prenatal and postnatal neuroprotection give some hope for the better outcome in the most severe cases. Unfortunately, obstetricians' awareness of the massive FMH remains still at an unacceptably low level., Summary: There is an urgent need for the internationally accepted definition, standardized pregnancy management protocol, and structured follow-up of neonates from such pregnancies. We suggest the international registry of massive FMH cases.

Introduction: Maternal death, during pregnancy or within 42 and 365 days from the end of pregnancy, was evaluated for a small high-income nation with comprehensive healthcare., Material and Methods: Cases were identified using record linkage by running national census information on all deaths of women aged 15-49 years during 1985-2009 against the national birth register and computerized hospital admission files for pregnancy-related diagnoses as well as actual case records where needed. Death certificates and hospital records were reviewed., Results: Thirty deaths were identified; 26 at ≥ 22 weeks (= birth) and four earlier in pregnancy. For 107,871 deliveries, the overall mortality was 27.8/100,000. There were five direct deaths (4.6/100,000 deliveries), five indirect deaths (4.6/100,000 deliveries) and 19 coincidental deaths (17.6/100,000 deliveries). Using WHO criteria (direct and indirect in pregnancy or at ≤ 42 days postpartum) the ratio was 5.6/100,000 deliveries (95% confidence interval 1.1-10.1) and 5.5/100,000 live births (maternal mortality ratio, based on six deaths). Direct deaths were caused by sepsis, severe preeclampsia and choriocarcinoma, indirect by suicide, pre-existing cardiac and diabetic illness. No woman died of postpartum hemorrhage, anesthesia or ectopic pregnancy. Suboptimal care occurred., Conclusion: Maternal mortality in Iceland over a 25-year period up to the end of year 2010 was low, between 5 and 6/100,000 births. A comprehensive national healthcare system with accessible antenatal care in a society with good general living conditions and universal education probably contributed to this., (© 2015 Nordic Federation of Societies of Obstetrics and Gynecology.)

A 26-year-old patient with recurrent choriocarcinoma of the testis presented with headache and progressive left homonymous hemianopsia. On initial MRI a grade 4 arteriovenous malformation (AVM) was identified in the right occipital lobe, which was further characterized by catheter angiography. Continued worsening of the headache in the following days prompted a follow-up MRI, which revealed a new T2 hypointense nodule and adjacent vasogenic edema in the periphery of the AVM. A follow-up MRI showed a marked increase in the size of the nodule with intrinsic enhancement and worsening perilesional edema. Based on the imaging evolution, the nodule was diagnosed as a metastasis and the patient was started on chemotherapy and radiotherapy. One week after the MRI he developed a sudden hemorrhage within the mass requiring decompression craniectomy and resection of both AVM and tumor. The histopathology of the resected mass confirmed the diagnosis of choriocarcinoma metastasis to the AVM., (Published by the BMJ Publishing Group Limited.
