Sudden death due to an invasive mole in a young primigravida: Precipitous presentation masquerading the natural manner

Exploring the real cause of hemoptysis: A case of pulmonary tumor embolism in a young woman with accompanying pulmonary metastasis of gestational trophoblastic neoplasia

We report a case of pulmonary embolism caused by gestational trophoblastic neoplasia (GTN) accompanied by pulmonary metastasis to improve the recognition ability of the disease in young female patients with pulmonary embolism and hemoptysis.

Gestational trophoblastic neoplasia: Novelties and challenges

Gestational trophoblastic diseases are a group of pregnancy-related disorders, originated from trophoblast cells. They include benign and aggressive tumors, such as the invasive mole, the choriocarcinoma, the placental site trophoblastic tumor (PSTT), and the epithelioid trophoblastic tumor (ETT). These malignancies are characterized as gestational trophoblastic neoplasm (GTN), rarer, although more dangerous. The diagnosis of GTN is made in most cases by monitoring serum chorionic gonadotropin (hCG) with histological confirmation. The use of specific tissue biomarkers has been increasingly employed as a differential diagnosis, leading to more accurate results and different therapy protocols and prognosis for each GTN. The treatment is based on the International Federation of Gynecology and Obstetrics anatomical staging system and the World Health Organization prognostic score system. If an accurate diagnosis is made and the guidelines followed, the cure for choriocarcinoma and invasive mole cases can reach 98%, whereas PSTT and ETT still present mild success rates. The improved knowledge about GTN and its peculiarities allows physicians to efficiently achieve the differential diagnosis and choose the best available therapy protocol, thus increasing the overall survival of affected women. Nevertheless, obtaining epidemiological data and improving knowledge through basic and translational research are essential to answer open questions on GTN physiopathology, their causes, and cellular behavior.

An invasive mole with pulmonary metastases in a 55-year-old postmenopausal Syrian woman: a case report and review of the literature

Background

Invasive mole is a subtype of gestational trophoblastic neoplasms (GTNs) that usually develops from the malignant transformation of trophoblastic tissue after molar evacuation. Invasive moles mostly occur in women of reproductive age, while they are extremely rare in postmenopausal women.

Case presentation

We present the case of a 55-year-old postmenopausal Syrian woman who was admitted to the emergency department at our hospital due to massive vaginal bleeding for 10 days accompanied by constant abdominal pain with diarrhea and vomiting. Following clinical, laboratory and radiological examination, total hysterectomy with bilateral salpingo-oophorectomy was performed. Histologic examination of the resected specimens revealed the diagnosis of an invasive mole with pulmonary metastases that were diagnosed by chest computed tomography (CT). Following surgical resection, the patient was scheduled for combination chemotherapy. However, 2 weeks later the patient was readmitted to the emergency department due to severe hemoptysis and dyspnea, and later that day the patient died in spite of resuscitation efforts.

Conclusion

Although invasive moles in postmenopausal women have been reported previously, we believe our case is the first reported from Syria. Our case highlights the difficulties in diagnosing invasive moles in the absence of significant history of gestational trophoblastic diseases. The present study further reviews the diagnostic methods, histological characteristics and treatment recommendations.

Methotrexate-induced hemothorax in a woman with low-risk metastatic gestational trophoblastic disease

•Patients with invasive mole have a risk of bleeding to fragility and vascularity of the tumor.•Some patients may experience life-threatening bleeding.•Chemotherapy of patients with invasive/metastatic mole may induce bleeding.•In our patient with pulmonary metastatic mole, massive hemorrhage occurred 2 h after the first dose of MTX.•Our patient was successfully treated with partial resection of the bleeding tumor and additional 2 cycles of MTX.
