Epithelioid trophoblastic tumor: A case series

An epithelioid trophoblastic tumor (ETT) is an extremely rare gestational trophoblastic tumor. Cases of ETT present with abnormal vaginal bleeding in women of reproductive age group with marginally elevated beta human chorionic gonadotrophin (B-hCG) levels. Here, we describe a series of four patients (all were females) including histomorphology, immunoprofiles, and diagnostic difficulty of this rare entity. All cases were in their reproductive age group. The mean pre-treatment hCG level was 665.24 (mIU/mL). Microscopically, all cases had a tumor showing an epithelioid appearance arranged in large nests and sheets. Individual tumor cells were round to polygonal with abundant eosinophilic cytoplasm, with central vesicular nuclei and prominent nucleoli. Areas of hemorrhage, necrosis, and intercellular hyaline-like material deposition were identified in all cases (100%). Immunohistochemically, tumor cells in all cases showed diffuse positivity for AE1/AE3 and p63 (100%). GATA3 was available in one case (25%), which was positive in the tumor cells. In one case (25%), hPL was focally positive, and in one case (25%), it was negative. SALL4 was performed in two cases (50%) and was negative in tumor cells. The mean Ki67 labeling index was 19.2 (range 10–30%). All four patients underwent surgical intervention and were treated with hysterectomy. The mean follow-up in this series was 39.4 months (range 6–70), and all patients are alive to date with a mean survival of 32.8 months (range, 4–67).

Early diagnosis and prompt management help in reducing mortality and morbidity occuring due to scar ectopic pregnancy. We are reporting a rare case of cesarean scar ectopic pregnancy G5P3L3D1 with period of gestation 7 weeks 3 days with previous all 4 deliveries by cesarean section. Cesarean scar ectopic pregnancy are life threatening as they pose a great risk of maternal hemorrhage as the patient vital are the stable patient managed medically with injection Methotrexate

Non-surgical diagnosis and management of chronic ectopic: A case report / The Health Sciences Journal

@#Chronic ectopic pregnancy is a rare form of ectopic gestation that contributes to the increased maternal morbidity and mortality in the frst trimester of pregnancy. Diagnosis is often challenging as it presents with subtle clinical signs and symptoms, imposing the need for surgical exploration and management. This is a case of a 27-year-old gravida 3 para 2 (2002) who presented with vaginal bleeding of three weeks duration, was hemodynamically stable with unremarkable physical examination fndings. The diagnosis of a chronic ectopic pregnancy was established with a conservative, non-surgical approach through the combination of clinical symptoms, transvaginal sonography, and b-hCG monitoring. Management was likewise conservative with multiple dose methotrexate chemotherapy, eventually yielding a decrease in b-hCG from 80.0 mIU/mL to 1.0 mIU/mL.

Study of demography and clinical profile of ectopic pregnancies in a tertiary level hospital in Uttarakhand: a five year review

Background: Ectopic pregnancy is a condition when a fertilized ovum is implanted outside the uterine cavity. Life threatening risk of rupture of ectopic pregnancy remains one of the important causes of maternal mortality in India. The aim of study is to analyse the clinical profile, associated risk factors, complications, treatment outcomes to improve maternal mortality and morbidity associated with ectopic pregnancy.Methods: It is a retrospective study conducted at Shri Guru Ram Rai Institute of Medical and Health Sciences from January 2015 to January 2020. A total of 182 patients diagnosed of Ectopic Pregnancy were analysed for clinical profile, risk factors, serology, ultrasound findings, complications, treatment offered and outcome.Results: During the study period of 5 years there were total 182 patients who were diagnosed of ectopic pregnancy showing the incidence of ectopic pregnancy in our hospital 1.4% of total number of deliveries. Majority of patients were in the age group of 25 to 30 years (43.95%). Mostly multiparous women (80.1%) had ectopic pregnancy. Majority of patients (56.1%) had no associated risk factors for ectopic pregnancy. Main presenting complain was abdominal pain in 58.8% of patients. Majority of patients (63.2%) had surgery as primary care which indicates delay in diagnosis and arrival at hospital especially in hilly region of Uttarakhand.Conclusions: Ectopic pregnancies need to be diagnosed timely to decrease maternal morbidities and mortalities.  Clinical signs and symptoms with serology (Serum beta hCG) and radiological findings helps to optimize treatment for potentially life-threatening condition.

The role of pregnancy-associated plasma protein-a level in the first trimester of pregnancy and clinical outcome in an urban referral centre

Background: Estimation of serum PAPP-A levels studied predictability for adverse perinatal outcome. This case control study tries to establish the association between low PAPP-A levels among the pregnant woman and adverse maternal foetal outcome.Methods: This is an case-control study during 2017-2018 in the women delivered at Department of OBG at Mehta Hospitals. Women delivered in the labour room  had a first trimester screening of PAPP-A level were explained, taken informed consent, questionnaire which include detailed antenatal history, mode of delivery and baby data.  Depending upon outcome, the subjects are classified as case group or control group, out of the study sample of 264 subjects, 88 patients who had complications were taken as cases and 176 patients with no complications taken as control were undertaken.Results: Low PAPP-A level (<0.5 MoM) showed high incidence of PIH and preeclampsia, followed by IUGR and Preterm. PAPP-A level >0.5 MoM, normal outcome is more than the adverse outcome. The difference in the PAPP-A levels is statistically significant. In women with low PAPP A level, low birth weight found statistically significant when compared with <0.5 PAPP A level. The sensitivity of PAPP A levels in identifying the complicated outcomes was 17.04%.The specificity was 98.85%. The positive predictive value of predicting the complications was 88.23% and negative predictive value of 70.44%.Conclusions: The low PAPP-A levels confirmed during first trimester of pregnancy is associated with adverse maternal and foetal outcome such as PIH, preeclampsia, preterm, IUGR and LBW.

A molar pregnancy detected by following irregular vaginal bleeding after a first trimester evacuation: rare case report

In this case report summarizes the sequence of events that led to detection of a molar pregnancy missed by ultrasound and initial pathology examination. A 29 years old Asian nulliparous patient came to our clinic with missed period. On beta HCG she was 6 weeks pregnant. After 20 days she was diagnosed with 7 weeks missed abortion on ultrasound. surgical evacuation done for same. After 3 weeks she came with irregular vaginal bleeding. After physical and vaginal examination Beta HCG done, which was very high. On transvaginal ultrasound partial molar pregnancy was detected, so she was immediately admitted and repeat surgical evacuation was done. Histopathology report confirmed partial molar pregnancy which was not detected in previous report. She was regularly followed up with Beta HCG value up to 1 year which declined dramatically. Though molar pregnancy is rare, but it has the potential to develop into invasive mole, so any abnormal bleeding post evacuation should be followed up properly. Beta HCG values and histopathological evaluation is important for correct diagnosis and follow up.

The comparison of beta-hCG levels according to treatment modalities in tubal pregnancy / 대한주산의학회잡지

OBJECTIVE: The aims of this study were to evaluate the effect of the methotrexate (MTX) method by comparing the change of the serum beta-hCG level between the MTX method and salpingectomy for treating tubal pregnancy, furthermore by analyzing differences between the MTX success group and the failure group, and to provide helps in establishing criteria for choosing the MTX method. METHODS: Medical records of the 118 patients who were diagnosed with tubal pregnancy were reviewed retrospectively for the period of January 2006 to December 2007 at Kangnam St. Marys Hospital. RESULTS: Between the MTX success group and the failure group, no difference was observed in pregnancy duration, but statistically significant differences were observed in the size of hematoma and the quantity of hemoperitoneum at the site of tubal pregnancy in ultrasonography and in the serum beta-hCG level (p<0.05). Compared with salpingectomy, the MTX method showed the patterns of a low decrease rate of serum beta-hCG level after treatment and even its increase during the early period of treatment, but the serum beta-hCG level decreased rapidly from Day 7 after treatment and became equal to that of salpingectomy on Day 28 after treatment. CONCLUSION: The size of hematoma and the quantity of hemoperitoneum at the site of tubal pregnancy and the serum beta-hCG level before treatment are important factors for success in the MTX method. The MTX method may be safe and effective relatively in hemodynamically stable tubal pregnancy patients, who need preserve the salpinx particularly.

Malignant gestational trophobalstic tumor with markedly elevated serum hCG levels and negative urine hCG level / 대한산부인과학회지

Gestational trophoblastic disease comprises a spectrum of interrelated conditions originating from the placenta. Malignant gestational trophoblastic disease refers to lesions that have the potential for local invasion and metastasis. This compromises many histological entities including hydatidiform moles, invasive moles, gestational choriocarcinomas, and placental site trophoblastic tumors. Before the advent of sensitive assays for human chorionic gonadotropin (hCG) and efficacious chemotherapy, the morbidity and mortality from gestational trophoblastic disease were substantial. Currently, with sensitive quantitative assays for beta-hCG and current approaches to chemotherapy, most women with malignant trophoblastic disease can be cured. We present a case of malignant gestational trophobalstic tumor with serum beta-hCG concentration over 1million IU/L that metastaze to the lungs and have a hyperthyroidism, but negative urine hCG testing. We report a case with a brief review of literatures.

A case of suprasellar germinoma misdiagnosed as lymphocytic hypophysitis / 대한내과학회지

We report here on a case of a 22-year-old girl with a suprasellar mass that was originally diagnosed as lymphocytic hypophysitis, but it eventually turned out to be a germinoma. She initially underwent partial tumor removal and the tissue diagnosis was suggestive of lymphocytic hypophysitis. 46 months later, she presented with a lateral visual field defect and decreased visual acuity of her right eye. The serum and cerebrospinal beta-hCG and alpha-fetoprotein levels were measured. The beta-hCG level was elevated in both, whereas the alpha-fetoprotein level was detectable in neither. The serum anti-pituitary antibody-1 level was negative. She was reoperated and the permanent section biopsies were compatible with pure germinoma. There was no evidence of meningeal metastasis on her whole spine MRI. She was treated with chemotherapy.

Midtrimester triple test in IVF/ICSI twin pregnancies / 대한산부인과학회지

OBJECTIVE: To compare the midtrimester triple marker levels for down syndrome screening between natural and IVF twin pregnancies and to evaluate the difference triple marker in IVF twin pregnancies according to the fertilization method and number of transferred embryos. METHODS: The study population consisted of conventional IVF twin (n=106), ICSI twin (n=142), and natural (n=436) twin pregnancies as controls between 2001 and 2004. All pregnancies in this study were known to have normal outcome. Maternal serum samples were collected between 14-18 gestational weeks. Levels of AFP, total hCG, and uE3 were measured and were expressed as multiples of the median (MoM) based on reference medians established at Cheil Hospital. RESULTS: The mean maternal age (31.6+/-2.8 vs. 31.6+/-3.0 vs. 32.1+/-2.1: conventional IVF group vs. ICSI group vs. control, respectively) and gestational weeks (16.0+/-0.5 vs. 16.0+/-0.7 vs. 16.1+/-0.2) for triple test were similar. There was no difference in levels of all serum markers between conventional IVF and ICSI group. The median AFP MoM for conventional IVF and ICSI group were significantly higher than that of the control group (2.40 vs. 2.22 vs. 1.98; p0.05). Also, the median hCG MoM was not different from that of the control group (2.04 vs. 2.06 vs. 2.02; p>0.05). There was no correlation in triple marker levels according to the number of transferred embryos in conventional IVF and ICSI groups. CONCLUSION: Midtrimester triple marker levels of IVF twin pregnancy for down syndrome screening are similar with those of natural twin pregnancy regardless of fertilization method and number of transferred embryos.

Human chorionic gonadotropin and invasion of trophoblast into the tubal wall in tubal pregnancy / 대한산부인과학회지

OBJECTIVE: To evaluate the relationship between gestational age, tubal ultrasonographic diameter, and serum beta-hCG levels and different stages of trophoblastic infiltration of the tubal wall in tubal pregnancy. METHODS: The 45 cases of fallopian tube containing tubal pregnancy were reviewed. Gestational age, diameter of the tubal mass, and beta-hCG level on the day of surgery were calculated by transvaginal sonography and immunoassay respectively. The tubal pregnancy was classified according to the depth of trophoblastic infiltration: trophoblast limited to the tubal mucosa (stage I), extension to the tubal muscularis (stage II), or complete tubal wall infiltration up to the serosa discontinued by trophoblastic cells (stage III). RESULTS: 14 patients (31.1%) had stage I tubal infiltration, 10 patients (22.2%) had stage II infiltration, 21 patients (46.7%) had stage III infiltration. There was no relationship between gestational age, tubal diameter and stage, but there was a predictable correlation between beta-hCG and the depth of trophoblastic invasion. The median beta-hCG level was 1,332.1 mIU/mL (range, 215-2,995 mIU/mL) for patients with stage I infiltration, 9,548.0 mIU/mL (range, 569-43,989 mIU/mL) for stage II infiltration, and 23,087.9 mIU/mL (range, 1,373-98,000 mIU/mL) for stage III infiltration. Cut off level of beta-hCG for each stage were 1,996.5 mIU/mL (stage I vs II, III) and 5,665 mIU/mL (stage I, II vs III) respectively. CONCLUSION: These findings may explain why beta-hCG is a important predicting factor for invasion of trophoblast in tubal pregnancy.

Clinical Guidelines for Methotrexate in Conservative Treatment for Ectopic Pregnancy / 대한산부인과학회지

OBJECTIVE: To provide more useful guidelines for methotrexate (MTX) treatment in ectopic pregnancy, including patient selection, therapeutic dose, and reproductive outcome. METHODS: Retrospectively, records of 54 patients treated for ectopic pregnancy with systemic MTX were reviewed. MTX was administered 1.0 mg/kg intramuscularly, alternatively with leucovorin 0.1 mg/kg intramuscularly for up to four daily doses of each drug. Samples for beta-hCG detection were obtained on days +3, +7 after beginning of the therapy and then weekly until values were undetectable. RESULTS: 50 patients (92.6%) were treated successfully. 4 patients (7.4%) for whom MTX therapy failed, were treated surgically. The endometrial thickness significantly increased in the failed group, compared to the successful group (14.3+/-4.0 mm vs 7.0+/-2.8 mm, P=0.0001). The serum hemoglobin levels significantly changed in the failed group, compared to the successful group (2.1+/-0.9 g/dL vs 1.0+/-0.8 g/dL, P=0.044). Patients were divided into increasing group and decreasing group according to beta-hCG levels on day 0, that were higher or lower than day -2 level. The resolution time of beta-hCG between increasing group and decreasing group was significantly different (27.6+/-14.0 days vs 17.7+/-8.6 days, p=0.016). In 8 patients (15.1%), an immediate rise of beta-hCG was recorded on day 3 after MTX treatment, but on day 7, a rapid decrease was recorded. Women were treated with significantly different therapeutic dose of MTX according to initial level of serum beta-hCG (p=0.021). There were mild complications (12%). MTX treatment preserved the fallopian tube and thus preserved fertility (70%). CONCLUSION: Systemic MTX use with the dose according to initial level of serum beta-hCG is a safe and highly effective treatment in clinically stable ectopic pregnancy.

Efficacy and Predictors of Success of Methotrexate Treatment in Women with Unruptured Tubal Ectopic Pregnancies / 대한산부인과학회잡지

OBJECTIVE: To evaluate the efficacy and predictors of success of methotrexate (MTX) treatment in selected cases of unruptured tubal pregnancies. METHODS: This study was retrospectively performed in 36 women who had diagnosed unruptured tubal pregnancies. Patients received intramuscular MTX. Serial beta-hCG measurement was performed weekly, and success was defined as the achievement to beta-hCG concentration of 10 mIU/mL without surgical intervention. Surgical intervention was performed for presumed tubal rupture. Pretreatment serum concentration of beta-hCG, the size of tubal mass and gestational sac by transvaginal ultrasonography were measured to evaluate the predictors of MTX therapy. RESULTS: 29 patients (81%) were successfully treated by MTX systematic treatment. There were not significant differences in the patient's age, parity, gestational age and the size of tubal ectopic mass, but significant differences in the gestational sac size and serum beta-hCG concentration between success group and failure group of MTX treatment. The mean time for achieving successful treatment was 33.8 days. The success rate of systemic MTX was significantly decreased and resolution time was prolonged if the initial pretreatment serum beta-hCG was 10,000 mIU/mL or gestational sac size was >or=1 cm. CONCLUSION: Pretreatment serum beta-hCG concentration and gestational sac size are important predictors of success of MTX treatment in women with unruptured tubal pregnancy.

The relation of beta-hCG levels before the artificial abortion and fetal age and the number of removed tissue of hydatiform mole

Study conducted on 57 cases of complete hydatiform mole, with the average fetal age of 13.5641.04 weeks (lowest 6 weeks, highest 20.5 weeks) beta-hCG average level 1158656.16246627.71 IU/l (min 79072 IU/l, max 5474400 IU/l), volume of removed tissue – min 100 ml, max 2500 ml). Results showed that the correlation between preevacuation beta-hCG level and removed tissue volume is higher than the correlation between gestational age and the number of evacuated mole. Between preevacuated beta-hCG level and gestational age the correlation is not valuable

A Case of Thyroid Storm Developed after Dilatation and Curettage for Invasive Molar Pregnancy / 대한내분비학회지

Thyroid dysfunction is one of the more prevalent clinical situations encountered by primary care physicians. Thyroid storm is defined as a life-threatening exacerbation of the hyperthyroid state in which there is evidence of decompensation of one or more organ systems. Common precipitants include infection, surgery, diabetic ketoacidosis, vascular accidents, non-compliance with antithyroid medication, and emotional stress, but rarely develop in invasive molar pregnancy. An 18-year-old woman presented to the emergency department complaining of lower abdominal pain and vaginal spotting. She had no previous history of hyperthyroidism. Under the diagnosis of invasive molar pregnancy, dilatation and curettage was performed. However, right after the procedure the patient developed a semi-coma metal status, high grade fever, and tachycardia. Prompt diagnosis of thyroid storm was made and treatment followed immediately. We present a case of thyroid storm and a review of thyroid storm precipitated by invasive molar pregnancy.

The Predictive Value of a Single Serum Beta Human Chorionic Gonadotropin Level in Pregnancies Achieved by Intrauterine Insemination and In Vitro Fertilization-Embryo Transfer Program / 대한산부인과학회잡지

OBJECTIVE: To clarify specific serum beta-human chorionic gonadotropin (beta-hCG) levels on 11 days after intrauterine insemination (IUI) and in vitro fertilization-embryo transfer (IVF-ET) that could predict live birth. METHODS: Three hundred ninety-two pregnancies resulting from IUI and IVF-ET procedures between January 1, 1997 and December 31, 2000 were evaluated. Serum quantitative beta-hCG levels were measured 11 days after IUI or ET using standard immunoradiometric assays. Pregnancy outcomes were categorized as spontaneous abortion, biochemical pregnancy, ectopic pregnancy, singleton live birth, or multiple live birth. Statistical analyses were performed by analysis of variances, and Student's t-test. The sensitivity and specificity of serum beta-hCG level for predicting live birth were plotted using receiver-operator-characteristic (ROC) curve. RESULTS: The multiple live birth group has significantly higher serum beta-hCG level among the different pregnancy outcome groups. The beta-hCG level on the eleventh day after IUI and IVF-ET was significantly higher in the live birth group than the non viable pregnancy group. At a threshold level of 65 mIU/ml, the serum beta-hCG level on the eleventh day after IUI had a positive predictive value of 78.9% in predicting live birth with 95% specificity. At a threshold level of 115 mIU/ml, the serum beta human chorionic gonadotropin level on the eleventh day after ET had a positive predictive value of 92.1% with 95% specificity. CONCLUSION: These data suggest that serum beta-hCG level on 11 days after IVF-ET could be a reliable indicator predicting pregnancy outcome.

The concentration of the amniotic fluid angiogenin and interleukin-6 in the pregnancy with elevated maternal serum human chorionic gonadotropin during the second trimester / 대한산부인과학회잡지

OBJECTIVE: This study is to measure the level of concentration of angiogenin, a cause of potent neovascularization and a marker of ischemia, and of interleukin-6 (IL-6), an indicator of acute inflammation, in the amniotic fluid of patients with elevated maternal serum free beta-hCG level during the second-trimester. MATERIALS AND METHODS: Twenty patients with elevated maternal serum free beta-hCG level (>2.5 MoM) at double screening test of Down syndrome were compared with the controlled group (<2.0 MoM). This study includes singleton gestation, gestational age of 14-18 weeks, and has no evidence of fetal structural and chromosomal anomalies. The levels of amniotic angiogenin and IL-6 were measured by enzyme-linked immunosorbent assay (ELISA) method. Data were analyzed by Mann-Whitney U test. p value <0.05 was considered significant. RESULTS: Amniotic angiogenin levels in the studied group were much lower than those in the controlled group (p<0.05), whereas the difference of IL-6 levels between the two groups was not significant. Nine studied patients delivered small for gestational age infants, but only one controlled patient (p<0.05) had the same infant. Other variables of perinatal outcome were not different between the two groups. CONCLUSION: That amniotic fluid angiogenin levels are significantly lower in patients with elevated maternal serum free beta-hCG suggests an inadequate angiogenesis. Elevated maternal serum free beta-hCG levels correlate with fetal growth restriction. IL-6 values in both groups have no significant difference.

Clinical usefulness of serum alpha-FP and free beta-hCG levels in midtrimester / 대한산부인과학회잡지

OBJECTIVE: The aim of this study was to evaluate the detection rate of the chromosomal abnormalities by screening of maternal serum alpha-FP, free beta-hCG in midtrimester and to evaluate the association of elevated free beta-hCG with neonatal & pregnancy outcome. METHODS: From October 1995 to December 1999, We studied 8,304 pregnant women who delivered in Asan Medical Center. We measured the levels of serum alpha-FP and free beta-hCG in the midtrimester. We reviewed high Down risk group, high NTD risk group and numerous cases of chromosomal abnormalities, retrospectively. To evaluate the association of elevated free beta-hCG with neonatal & pregnancy outcome, we reviewed birth weight, apgar score, gestational age at delivery, presence of PIH or fetal growth restriction. RESULTS: Two hundred ninety eight (3.6%) women were screened as high Down risk pregnancy, 61 (0.7%) women were screened as high NTD risk pregnancy. In the high risk group of chromosomal abnormalities, there were 13 cases of various chromosomal abnormalites, including of six Down syndrome baby. In the low risk group, there were two (0.02%) Down syndrome baby and 8 cases of other chromosomal abnormality. By using maternal serum alpha-FP, free beta-hCG in mid-trimester, 68% of the detection rate of chromosomal abnormalites and 4.1% of false positive rate was reported. The detection rate of Down syndrome is 75% (6/8) and 3.5% of false positive rate, 0.02% of false negative rate were reported. In the aspect of pregnancy outcome, when the free beta-hCG more than 2.5MOM, there were more numerous preterm delivery (8.2% vs 3.8%), IUGR (4.6% vs 1.7%), lower 1 min apgar score than 7 (6.4% vs 2.7%). CONCLUSION: Maternal serum alpha-FP, free beta-hCG is at least useful method as Double markers screening method for fetal chromosomal abnormalites and maybe elevated free beta-hCG level can be useful marker of poor pregnancy outcome such as PIH, low birth weight or preterm delivery.

Poorly Differentiated Endometrial Adenocarcinoma with Trophoblastic Differentiation / 대한산부인과학회잡지

Trophoblastic differentiation in gynecologic nontrophoblastic tumor is very rare. Here we present a 66-year-old female with poorly differentiated endometrial carcinoma showing trophoblast-like differentiation. This tumor was in advanced stage with metastases to lung, liver, and bone at diagnosis. The multinucleated, syncytiotrophoblast-like cells were positive for beta-human chorionic gonadotropin (beta-hCG) by immunochemical stain. The level of beta-hCG was also elevated (219 mIU/ml) in the patient's serum, but dropped after surgery and chemotherapy. beta-hCG may be used as tumor marker in this case.
