Pure primary non-gestational choriocarcinoma originating in the ovary: A case report and literature review

SEVERE DISEASE PROGRESSION OF POSTMOLAR GESTATIONAL NEOPLASM IN A VIETNAMESE YOUNG FEMALE PATIENT AFTER TREATMENT REFUSAL: INSIGHTS FROM A CASE REPORT AND LITERATURE REVIEW

Choriocarcinoma is characterized as the most aggressive malignant alternation of gestational trophoblastic neoplasm; however, this illness is a curable malignancy. Although a rarity, this disease affects a female patient's life and causes a fatal condition. Choriocarcinoma is a life-threatening disease since it is initially insidious and can rapidly lead to masive hemorrhage, even death. Choriocarcinoma should be suspected in childbearing-age women with the high-risk scores according to FIGO. The study aims to report a severe case of widespread metastatic choriocarcinoma to optimize the treatment with multiagent chemotherapy and a multidisciplinary cooperation at our center. A G1P0 20-year-old woman was referred to the hospital for suspicion of metastatic choriocarcinoma after self-stopping chemotherapy because of the COVID-19 pandemic. During hospitalization, the tumor metastasized and presented profuse intraabdominal hemorrhage. The patient underwent immediate surgical intervention to control bleeding, and a definitive diagnosis was accurately established by the histopathological examination. After surgery, the EMA/CO regimen was administered as the first line of treatment, despite the patient being in a coma and requiring a ventilator machine. After 6 cycles of the EMA/CO regimen, her serum β-hCG level decreased to 8 mUI/mL, however, her β-hCG concentration was not down to a negative value. Thus, the patient received paclitaxel/cisplatin alternating with paclitaxel/etoposide (TP/TE regimen) for complete remission following 2 cycles. The delays in choriocarcinoma treatment are prognostic factors for worse outcomes, whereas chemotherapy may be considered a suitable treatment even in a patient's coma, thus improving a prognosis substantially.

Non-gestational Choriocarcinoma of the Ovary: A Report of a Rare Case From Saudi Arabia

Non-gestational choriocarcinoma of the ovary is extremely rare and presents diagnostic and therapeutic challenges. Early recognition, appropriate surgical intervention, and adjuvant chemotherapy are essential for successful management. This case underscores the importance of considering choriocarcinoma in the differential diagnosis of ovarian tumors, especially in perimenopausal women with vascular mass. We present the case of a 47-year-old sexually active woman with a history of pelvic pain, diagnosed with non-gestational choriocarcinoma of the ovary. The patient underwent total abdominal hysterectomy and bilateral salpingo-oophorectomy with successful management using the bleomycin, etoposide, and platinum (BEP) regimen. This case highlights the importance of early detection and appropriate management of this rare entity.

Primary cesarean scar choriocarcinoma: A case series and literature review

OBJECTIVES

To provide clinical guidance for early diagnosis and effective management of primary cesarean scar choriocarcinoma, which is an extremely rare but highly malignant trophoblastic tumor.

METHODS

This retrospective case series summarized the clinical courses of seven patients diagnosed with cesarean scar choriocarcinoma.

RESULTS

We identified two patients in our institution with cesarean scar choriocarcinoma. In addition, details of the previous five patients were extracted from databases and analyzed to provide more clinical information. The seven patients had an average age of 31.14 years, their tumor sizes ranged from 2.0 to 6.5 cm, and their pretreatment serum β-human chorionic gonadotropin (β-hCG) levels ranged from 3664 to 312 468 mIU/mL. All the patients were categorized as having FIGO Stage I disease, with four patients at low risk and three at high risk. Six of the seven were misdiagnosed with ectopic pregnancy before pathologic examination.

CONCLUSIONS

Clinicians should pay attention to masses in cesarean scar and to continuous elevation of serum β-hCG levels after treatment. When cesarean scar choriocarcinoma is suspected, diagnostic surgery can be chosen for tentative treatment and pathologic sampling. Salvage EMA-CO chemotherapy (etoposide, actinomycin D, methotrexate, cyclophosphamide and vincristine) should be performed as early as possible to prevent metastasis and recurrence after pathologic diagnosis.

Non-Gestational Ovarian Choriocarcinoma: A Rare Ovarian Cancer Subtype

Non-Gestational Ovarian Choriocarcinoma (NGOC) is an extremely rare ovarian tumor, with an incidence of less than 0.6% of malignant ovarian germ cell tumors. Its close pathologic resemblance to Gestational Ovarian Choriocarcinoma (GOC), however, requires special attention as the treatments differ greatly. NGOC typically affects patients in late adolescence or early reproductive years. As a result, NGOCs are often misdiagnosed as ectopic pregnancies due to their common presentation of bleeding, abdominal pain, adnexal mass, and positive serum beta-HCG. On pathologic examination, the tumor is indistinguishable from GOC, and only after review of tissue for paternal genetic components can the diagnosis of NGOC be made. Imaging studies often show highly vascular lesions with further investigation with computer topography (CT) sometimes showing metastatic lesions in the lungs, pelvis, vagina, and liver. These lesions are often hemorrhagic and can lead to catastrophic bleeding. Treatment is vastly different from GOC; NGOC requires treatment with both surgical resection and chemotherapy, with Bleomycin, Etoposide, and Cisplatin (BEP) being the most used regimen. With correct diagnosis and treatment, patients can often receive fertility sparing treatment with long term survival.
