Video Hysteroscopy in the Diagnosis of Molar Pregnancy in two Challenging Situations: Complete Mole with Normal hCG and Partial Mole with Early Gestational Age.

STUDY OBJECTIVE: To present the first hysteroscopic findings of 2 cases of complete hydatidiform mole (CHM) and partial hydatidiform mole (PHM) within the context of the patients' clinical histories. DESIGN: Presentation of 2 hysteroscopic videos with narration of the intrauterine findings of molar pregnancy (MP) from Rio de Janeiro Gestational Trophoblastic Disease Reference Center. SETTING: MP is characterized by abnormal fertilization that generates 2 clinical syndromes: CHM and PHM [1]. INTERVENTIONS: In the first case, the patient was aged 50 years, and hysteroscopy was indicated to assess abnormal uterine bleeding in the presence of normal serum human chorionic gonadotropin (hCG) and transvaginal ultrassonography showing an endometrial cavity with heterogeneous content. Hysteroscopy found translucent hydropic structures diagnosed as CHM. The negative hCG value was due to the hook effect (hCG after dilution: 2 240 000 IU/L). In the second case, an 18-year-old patient underwent hysteroscopy to assess the endometrial cavity with retained abortion at 7 weeks in which, during conservative management, the hCG level increased over 4 weeks from 25 000 IU/L to 58 000 IU/L. Hysteroscopy visualized the embryo with its umbilical cord and hydatidiform vesicles diagnosed as PHM. CONCLUSION: MP can be an incidental finding during hysteroscopy for abnormal uterine bleeding or retained abortion [2-4]. Knowing its morphology during hysteroscopy is helpful for the correct management of this uncommon clinical situation. Hysteroscopy as an adjunct diagnostic tool (not as first-line treatment for MP) can be of significant benefit in challenging clinical scenarios. Further studies should assess the possible risk of spreading molar cells into the peritoneal cavity owing to hysteroscopic fluid.

Partial molar pregnancy with live fetus complicated by intrauterine growth restriction and severe preeclampsia. Case report and review of the literature / Mola parcial con feto vivo, complicado con restricción de crecimiento intrauterino y preeclamsia severa. Reporte de caso y revisión de la literatura

OBJECTIVE: To report the case of a partial molar pregnancy with live fetus and conduct a review of the literature regarding maternal and fetal complications associated to this condition. METHODS: Case report of a partial mole with a 33 weeks live fetus complicated by intrauterine growth restriction, oligohydramnios and severe preeclampsia. We report satisfactory maternal and neonatal outcomes and 1-year follow-up. A search was conducted in the Medline via Pubmed, Lilacs, Ovid, Uptodate and Google Scholar databases using the following MESH terms: hiditadiform mole, partial mole, live fetus, coexisting live fetus. Case series and case reports of pregnant women with coexisting partial mole and live fetus at the time of diagnosis were selected and information regarding maternal and fetal prognosis was extracted. RESULTS: Initially, 129 related titles were identified. Of these, 29 met the inclusion criteria, and 4 articles were excluded due to failed access to the full text. Overall, 31 reported cases were included; 9 ended in miscarriage, 8 in fetal demise or perinatal death, and 14 (45 %) resulted in a live neonate. The most frequent maternal complication was preeclampsia in 6 (19.35 %) cases. CONCLUSIONS: The coexistence of a partial mole with a live fetus poses a high risk of adverse perinatal outcomes and preeclampsia. The volume of information regarding this rare condition must be increased in order to better determine potential interventions in cases of euploid fetuses and to provide adequate counseling in clinical practice. Therefore, reporting these cases is important to build sufficient evidence about the natural course of this condition.

TITULO: MOLA PARCIAL CON FETO VIVO, COMPLICADO CON RESTRICCIÓN DE CRECIMIENTO INTRAUTERINO Y PREECLAMSIA SEVERA. REPORTE DE CASO Y REVISIÓN DE LA LITERATURA. OBJETIVO: Reportar un caso de mola parcial con feto vivo y realizar una revisión de la literatura sobre las complicaciones maternas y fetales asociadas a esta condición. METODOS: Se presenta el reporte de un caso de mola parcial y feto vivo de 33 semanas, complicado por restricción de crecimiento intrauterino, oligoamnios y preeclampsia severa. Después de seguimiento del recién nacido a un año reportamos un resultado satisfactorio materno-fetal. Se realiza una búsqueda de la literatura en Medline vía PubMed, Lilacs, OVID, Uptodate y Google Scholar, con los siguientes términos MESH: "hiditadiform mole", "partial mole", "live fetus", "coexisting live fetus". Se seleccionaron estudios de series de caso y reportes de caso de gestantes con coexistencia de mola parcial y feto vivo al momento del diagnóstico, y se extrajo información sobre el pronóstico materno-fetal. RESULTADOS: Se identificaron inicialmente 129 títulos relacionados, de los cuales 29 cumplieron los criterios de inclusión, 4 artículos fueron excluidos por no obtener acceso al texto completo. Se analizaron 31 casos reportados, 9 casos terminaron en aborto, 8 terminaron en óbito o muerte perinatal y 14 (45 %) casos terminaron con un recién nacido vivo. La complicación materna más frecuente fue preeclampsia, en 6 (19,35 %) casos. CONCLUSIONES: La coexistencia de mola parcial con feto vivo presenta un riesgo alto de resultado perinatal adverso y preeclampsia. Se requiere más información sobre esta rara condición para determinar de mejor manera posibles intervenciones en los casos de fetos euploides y dar una adecuada asesoría en la práctica clínica, por lo que es importante el reporte de estos casos para tener suficiente evidencia sobre el comportamiento natural de la enfermedad.

Reporte de un caso: embarazo gemelar con un feto vivo y mola completa / Case report: twin pregnancy with a live fetus and complete mole

RESUMEN La coexistencia de una mola completa y un feto vivo es una condición infrecuente que puede evolucionar con múltiples complicaciones tanto maternas como fetales; entre ellas aborto, preeclampsia, hipertiroidismo, metrorragia, parto pretérmino y enfermedad trofoblástica gestacional persistente. No existe consenso internacional respecto al manejo de esta condición, aun conociéndose el mal pronóstico para el feto y los elevados riesgos maternos asociados. El siguiente es un reporte de un caso clínico de embarazo gemelar con feto vivo y mola completa, diagnosticado a las 12+1 semanas. Luego de realizar consejería, y en contexto de la legislación chilena en el año 2015, se decide continuar con el embarazo. La paciente es monitorizada en policlínico de alto riesgo obstétrico con controles seriados de b-HCG, ecografía fetal y RNM pélvica. Desde las 13 semanas presenta hipertensión arterial que se maneja con antihipertensivos orales; posteriormente, a las 20+2 semanas, desarrolla un cuadro de preeclampsia severa por lo que, en conjunto con la paciente, se decide realizar histerectomía en bloque. Dada la persistencia de valores de b-HCG elevados a las 12 semanas post interrupción del embarazo, se decide tratamiento con metotrexato. El caso fue analizado en Comité de Ginecología Oncológica donde se decidió seguimiento con b-HCG, lográndose la negativización a las 38 semanas post metotrexato. Se confirmaron valores negativos de b-HCG por 6 meses, tras lo cual fue dada de alta.

ABSTRACT The coexistence of a complete mole and an alive fetus is a rare condition that can evolve with multiple complications both maternal and fetal; among them abortion, preeclampsia, hyperthyroidism, uterine bleeding, preterm labor and persistent gestational trophoblastic disease. There is no international consensus regarding the management of this condition, despite the poor prognosis for the fetus and the associated high maternal risks. The following is a report of a clinical case of twin pregnancy with live fetus and complete mole, diagnosed at 12+1 weeks. After counseling, and in the context of Chilean legislation in 2015, it is decided to continue with pregnancy. The patient is monitored in a high-risk pregnancy outpatient clinic with follow ups b-HCG, fetal ultrasound and pelvic MRI. From 13 weeks, the patient presents high blood pressure that is managed with oral antihypertensives; and later, with 20+2 weeks, developed severe preeclampsia which is why, in conjunction with patient, it was decided to perform a block hysterectomy. Given the persistence of elevated b-HCG values at 12 weeks post-termination of pregnancy, treatment with methotrexate was decided. The case was analyzed in the local Committee of Oncological Gynecology, in which it was decided to follow the b-HCG curve, achieving negative values at 38 weeks post-methotrexate. Negative values of b-HCG were confirmed for 6 months, after which it was discharged.

Mola hidatiforme como manifestación ginecobstétrica en el curso de las enfermedades reumáticas / Hydatiform mole as a gynecological manifestation in the course of rheumatic diseases

Las enfermedades reumáticas pertenecen a un grupo que provocan manifestaciones clínicas en varios sistemas de órganos de la anatomía humana. Las complicaciones ginecobstétricas no son las que con mayor frecuencia se presentan. La enfermedad trofoblástica gestacional agrupa un conjunto de lesiones benignas como la mola hidatiforme y la neoplasia trofoblástica gestacional. Este trabajo se propone presentar un caso con los elementos clínicos e imagenológicos que permiten llegar al diagnóstico de una mola hidatiforme. Se trata de una paciente de 48 años de edad, con diagnóstico de lupus eritematoso sistémico, que acude con manifestaciones clínicas que permitieron llegar al diagnóstico de enfermedad trofoblástica gestacional con mola hidatiforme completa. Las enfermedades reumáticas, en especial el lupus eritematoso sistémico, provocan complicaciones ginecobstétricas. La enfermedad trofoblástica gestacional con mola hidatiforme completa, a pesar de ser una rara entidad, afecta considerablemente el bienestar biopsicosocial de las pacientes y disminuye su percepción de calidad de vida relacionada con la salud(AU)

Rheumatic diseases fit in a group that cause clinical manifestations in various organ systems of the human anatomy. Gyneco-obstetric complications are those that occur less frequently. Gestational trophoblastic disease groups together benign lesions such as hydatidiform mole and gestational trophoblastic neoplasia. This paper intends to present a case with the clinical and imaging elements that allow the diagnosis of hydatidiform mole. We present a 48-year-old female patient with a diagnosis of systemic lupus erythematosus, who presents with clinical manifestations that led to the diagnosis of gestational trophoblastic disease with complete hydatidiform mole. Rheumatic diseases, especially systemic lupus erythematosus, cause gyneco-obstetric complications. Although being a rare entity, the gestational trophoblastic disease with complete hydatidiform mole greatly affects the biopsychosocial wellbeing of patients and decreases their perception of health-related quality of life(AU)

"Bunch of grapes" in complete hydatidiform mole.

Complete hydatidiform mole is a common cause of gestational bleeding of the first trimester, commonly assessed by ultrasound. It represents an abnormal proliferation of trophoblastic tissue, with no fetal formation, just hydropic villi. These abnormal villi seen in ultrasound are compared to a "bunch of grapes," a classic description of this disease.

Eclampsia como manifestación clínica de enfermedad trofoblástica gestacional: reporte de caso / Eclampsia as clinical presentation of gestational trophoblastic disease: case report

Introducción: La eclampsia es una complicación severa y poco frecuente del embarazo, apareciendo generalmente luego de las 34 semanas de edad gestacional. El diagnóstico de preeclampsia antes de las 20 semanas de edad gestacional se asocia con patología del trofoblasto. Presentación del caso: Paciente femenina de 18 años, 3 embarazos, 0 partos, 2 abortos, cursando embarazo de 14 semanas de edad gestacional, consulta por haber presentado síndrome convulsivo con crisis generalizadas de tipo tónico-clónicas y amaurosis posterior. Se sospecha síndrome de hipertensión endocraneana y se solicita resonancia magnética de encéfalo, que muestra múltiples lesiones córtico-subcorticales, sugiriendo síndrome de encefalopatía posterior reversible. Una ecografía obstétrica informa placenta aumentada de tamaño con múltiples imágenes econegativas con aspecto de panal de abeja, oligohidroamnios y feto con latidos positivos, sin anomalías anatómicas. La gonadotrofina coriónica humana fue de 11538440 U/L. Evoluciona con compromiso de conciencia y tres episodios de convulsión generalizada de tipo tónico-clónica con mala respuesta a diazepam y adecuada respuesta a sulfato de magnesio. Se pesquisa crisis hipertensiva y proteinuria de 24 horas de 8 gramos. Se decide interrupción del embarazo y manejo en Unidad de Paciente Crítico. Legrado aspirativo sin incidentes. La biopsia indica mola hidatidiforme parcial con feto sin malformaciones externas. Evolución favorable con negativización de gonadotrofina coriónica humana en controles posteriores. Discusión: El desarrollo de eclampsia antes de las 20 semanas es anecdótico con pocos casos reportados y su aparición debe hacer sospechar una patología del trofoblasto.

Introduction: Preeclampsia is a severe complication of pregnancy, usually appearing after 34 weeks of gestational age. The diagnosis of preeclampsia before 20 weeks of gestational age is associated with trophoblastic disease. Case report: Female patient, 18 years old, 3 pregnancies, 0 deliveries, 2 abortions, 14 weeks pregnant. Presents with generalized tonicclonic seizures and amaurosis. Clinical evaluation compatible with intracranial hypertension síndrome and magnetic resonance imaging of the brain is requested, showing multiple cortico-subcortical lesions, suggesting posterior reversible encephalopathy syndrome. Ultrasound evaluation informs increased size placenta, multiple echo-negativa images with honeycomb disposition, oligohydramnios and present fetal heartbeats. No fetal anatomic abnormalities. Human chorionic gonadotrophin level was 11538440 U/L. Clinical presentation evolves with impaired conscousness and three generalized tonic-clonic crisis, showing poor response to intravenous diazepam and appropriate response to magnesium sulfate. Hypertensive crisis develops and the result of 24 hour proteinuria is 8 grams. Due to mater nal risk pregnancy was interrupted and uterine aspirage was performed. Patient was managed in the Intensive Care Unit. Biopsy informed partial hydatidiform mole and fetus with no anatomical abnormalities. Clinical evolution was positive and human chorionic gonadotrophin level below detection during follow-up. Discussion: Development of eclapsia before 20 weeks of gestational age is anecdotal with few reported cases and could be indicative of gestational trophoblastic disease.

Mola invasiva / Invasive mole

La mola invasiva es poco frecuente y se caracteriza por la excesiva proliferación trofoblástica y penetración del trofoblasto dentro del miometrio, pero sin tendencia hacia la diseminación metastásica. El objetivo del trabajo es presentar un caso diagnosticado de neoplasia trofoblástica gestacional, tipo mola invasiva. Se realizaron estudios complementarios como: ecografía transabdominal, determinaciones de la fracción beta de la gonadotropina coriónica humana y una biopsia endometrial por legrado uterino. El resultado fue embarazo molar. Al ingreso le fue administrado metotrexato sistémico 25 mg intramuscular y ácido folínico un ámpula intramuscular de 15 mg diariamente, ambos durante cinco días. Posteriormente, a los 20 días se realizó histerectomía total abdominal sin anexectomía. La evolución clínica fue por consulta externa. Además, se realizó: radiografía de tórax, ultrasonografía de pelvis, dosificación de gonadotropina coriónica humana en su fracción beta, hemograma completo, tiempo de coagulación, sangramiento y transaminasa glutámico pirúvica evolutivas. En el manejo de la mola invasiva el tratamiento médico combinado con el quirúrgico fue efectivo y bien tolerado por la paciente.

Invasive mole is an infrequent condition characterized by excessive trophoblastic proliferation and trophoblast penetration into the myometrium, without a tendency to metastatic dissemination. The purpose of the study is to present a case diagnosed with gestational trophoblastic neoplasia of the invasive mole type. The following complementary tests were performed: transabdominal echography, human chorionic gonadotropin beta subunit determinations, and endometrial biopsy by uterine curettage. The result was molar pregnancy. Upon admission the patient was administered systemic methotrexate 25 mg intramuscularly, as well as an intramuscular ampoule of folinic acid 15 mg daily, both during five days. Total abdominal hysterectomy without anexectomy was performed 20 days later. Clinical evolution was followed up on an outpatient basis. The following tests were also performed: chest radiography, pelvic ultrasonography, human chorionic gonadotropin beta dosage, complete blood count, clotting time, bleeding and evolutive glutamic-pyruvic transaminase. During management of the invasive mole, the combination of clinical and surgical treatments proved effective and was well assimilated by the patient.

Complicações clínicas da gravidez molar / Clinical complications of hydatidiform mole

A gravidez molar, espectro benigno da doença trofoblástica gestacional, representa uma complicação obstétrica da primeira metade da gestação. De maneira geral, cursa com sintomatologia exuberante: hemorragia, útero aumento para a idade gestacional, cistose ovariana e pré-eclâmpsia precoce; chegando mesmo a graves situações clínicas de hipertireoidismo e insuficiência respiratória.Todavia, devido ao diagnóstico precoce da mola hidatiforme, ainda no primeiro trimestre, mercê da ultrassonografia, houve uma importante redução na ocorrência desses sintomas; contribuindo para que a condução desses casos excepcionais ficasse confinada aos Centros de Referência. É objetivo desse artigo apresentar ao obstetra brasileiro uma revisão das complicações clínicas da gravidez molar, atualizando-o no diagnóstico precoce e tratamento dessas condições clínicas que podem ser potencialmente ameaçadoras à vida da gestante e de seu concepto.(AU)

The molar pregnancy, in the benign gestational trophoblastic disease spectrum, represents an obstetric complication of first half of gestation. In general, runs with exuberant symptoms: bleeding, uterus increase for gestational age, ovarian cistose and early preeclampsia; even serious clinical situations of hyperthyroidism and respiratory failure. However, due to the early diagnosis of hydatidiform mole, still in the first trimester, through ultrasound, there was a significant reduction in the occurrence of these symptoms; contributing so that the conduct of these exceptional cases could be confined to the centers of reference. The purpose of this article is to present to the Brazilian obstetrician a review of clinical complications of molar pregnancy, updating it in the early diagnosis and treatment of clinical conditions that can be potentially threatening to the life of the pregnant woman and her fetus.(AU)

Sonographic diagnosis of complete mole and co-existent fetus: case report.

Coexistence of a complete mole and a normal fetus is a rare event. First trimester sonographic appearance of a complete molar pregnancy with a coexistent fetus and its sonographic differentiation from entities that may simulate a hydatidiform mole in its early stages is discussed. The reported case is one of a 19 y/o woman G2P1001 who was hospitalized several times for abnormal uterine bleeding. Characteristically, the sonographic appearance of a hydatidiform mole is of a moderately echogenic, multicystic intrauterine soft tissue mass. In this particular case, the initial presentation was that of a complex intrauterine fundal mass adjacent to a normal embryo, thus molar pregnancy was considered as part of the differential diagnosis. Doppler evaluation of the echogenic intrauterine mass has been proposed in addition to HCG evaluation, in order to differentiate from trophoblastic and non-trophoblastic disease. In differentiating between a partial and a complete molar pregnancy it is most important to realize that the diagnosis is difficult by ultrasonography because both present with the same multicystic or vesicular pattern. However, if there is a coexistent fetus such as in our reported case, the differentiation would be possible on basis of the presence of a sonographically normal placenta separated from the degenerated placenta.

[Cases of hydatidiform mole at the Nuevo Hospital Civil in Guadalajara]. / Mola hidatidiforme en el Nuevo Hospital Civil de Guadalajara.

Thirty nine patients with hydatiform mole with clinical, echosonographic and hormonal diagnosis, were analyzed, from March, 1991 to February 1993 at the Nuevo Hospital Civil de Guadalajara. Incidence was I out of 301 pregnancies; average age, 24.6 years; 35.8% were primigravidae; average amenorreha was 15.6 weeks and there were not complications in 84.6%. The most frequent symptoms were transvaginal bleeding, 92.3%; mole rests expulsion, 25.6% and hyperemesis, 23%. The uterine fundus was larger in 17 patients; smaller in 13; the same in 5 and there were no data for four cases. An uterine curettage was performed in 38 patients; there was hysterotomy performed also for important bleeding; and there were 11 patients transfused. The histopathologic results of hydatidiform mole were confirmed in 84.6%. Only 20% of the patients came back for a post-evacuation control treatment. These results suggest that the characteristics of mola pregnancy at the Nuevo Hospital Civil de Guadalajara are similar to what has been reported in the literature; with a delayed diagnosis and a poor follow up of cases.

[Gestational trophoblastic disease. Prevalence and epidemiologic features at the IMSS Torreón Medical Center]. / Enfermedad trofoblástica gestacional. Prevalencia y características epidemiológicas en el Centro Médico IMSS Torreón.

From August 1st, 1987, to August 31 1989, there were 18 patients with trophoblastic gestational disease (TGD). In that time there 12,263 births for a frequency of TGD of 1:681, the prevalence was 14.6 X 10,000 births. The most frequent symptom was nausea and the most frequent sign, abnormal uterine bleeding; uterine growth not accord to gestational age was not a constant sign. Ultrasound was the method of diagnosis and in all of the cases there were confirmation of diagnosis by tissue exam. The follow-up of the patients was done by standard protocol; oral contraceptives were used for family planning. Our findings are discussed and compared with those in the literature.
