Abstract
OBJECTIVE To describe the clinical and ultrasound characteristics of three types of rare malignant ovarian germ cell tumor: embryonal carcinoma, non-gestational choriocarcinoma and malignant mixed germ cell tumor. METHODS This was a retrospective multicenter study. From the International Ovarian Tumor Analysis (IOTA) database, we identified patients with a histological diagnosis of ovarian embryonal carcinoma, non-gestational choriocarcinoma or malignant mixed germ cell tumor, who had undergone preoperative ultrasound examination by an experienced ultrasound examiner between 2000 and 2020. Additional patients with the same histology were identified from the databases of the departments of gynecological oncology in the participating centers. All tumors were described using IOTA terminology. Three examiners reviewed all available ultrasound images and described them using pattern recognition. RESULTS One patient with embryonal carcinoma, five patients with non-gestational ovarian choriocarcinoma and seven patients with ovarian malignant mixed germ cell tumor (six primary tumors and one recurrence) were identified. Seven patients were included in the IOTA studies and six patients were examined outside of the IOTA studies. The median age at diagnosis was 26 (range, 14-77) years. Beta-human chorionic gonadotropin levels were highest in non-gestational choriocarcinomas and alpha-fetoprotein levels were highest in malignant mixed germ cell tumors. Most tumors were International Federation of Gynecology and Obstetrics (FIGO) Stage I (9/12 (75.0%)). All tumors were unilateral, and the median largest diameter was 129 (range, 38-216) mm. Of the tumors, 11/13 (84.6%) were solid and 2/13 (15.4%) were multilocular-solid; 9/13 (69.2%) manifested abundant vascularization on color Doppler examination. Using pattern recognition, the typical ultrasound appearance was a large solid tumor with inhomogeneous echogenicity of the solid tissue and often dispersed cysts which, in most cases, were small and irregular. Some tumors had smooth contours while others had irregular contours. CONCLUSIONS A unilateral, large solid tumor with inhomogeneous echogenicity of the solid tissue and with dispersed small cystic areas in a young woman should raise the suspicion of a rare malignant germ cell tumor. This suspicion can guide the clinician to test tumor markers specific for malignant germ cell tumors. © 2020 International Society of Ultrasound in Obstetrics and Gynecology.

Abstract
Choriocarcinoma is categorized as either gestational or nongestational depending on its origin. Nongestational choriocarcinoma originated in the trophoblastic differentiation is a rare but an aggressive tumor. This article reports a nongestational case of a uterine endometrial carcinoma with trophoblastic differentiation. A 54-year-old woman with a history of atypical genital bleeding that underwent semi-radical hysterectomy, bilateral salpingo-oophrectomy, and pelvic lymph nodes dissection. Pathological investigation showed that the tumor had endometrioid adenocarcinoma and choriocarcinomatous components. Although a series of multimodality treatments including craniotomy were performed, she died of aggressive lung and brain metastases one year after the primary surgery.

Abstract
Nongestational ovarian choriocarcinomas are extremely rare and pose diagnostic challenges in reproductive-aged patients because of elevated human chorionic gonadotrophin (hCG). A 23-year-old nulliparous Chinese woman with nongestational ovarian choriocarcinoma escaped diagnostic testing and was initially treated for an ectopic pregnancy. Three months after her first visit, a diagnostic laparoscopy demonstrated a nongestational ovarian choriocarcinoma. Comprehensive surgical staging was performed by laparoscopy. The tumor was confined to the left ovary. The patient was categorized as FIGO Stage IA. She was given four courses of combined chemotherapy after laparoscopic surgery and has been disease-free for 36 months.

Abstract
A 31-year-old woman with a history of infection with human papilloma virus was found to have an elevated human chorionic gonadotropin level (beta-HCG) of more than 9000 IU/L in January 2006. The patient reported an irregular menstrual cycle. Extensive clinical work-up including gynecologic examinations with laparoscopy, hysteroscopy, and curettage were performed but no pathologic explanation of this elevated beta-HCG could be found. In the initial computed tomography (CT) of the abdomen and the thorax, a tumor could not be detected. Based on a clinical decision, chemotherapy with methotrexate in a dose of 1 mg/kg body weight was started. Four months after beginning of the chemotherapy the beta-HCG level dropped to 3048 IU/L. At this time a first F-18 FDG PET was performed and the findings were negative. After completion of 7 cycles of chemotherapy the beta-HCG level rose again. In a second F-18 FDG PET in August 2006 focal, intense and pathologic F-18 FDG accumulation with a SUV max. of 5.4 was seen in the mediastinum in the region of the thymus. At this time the beta-HCG level was 7000 IU/L. In a subsequent CT of the chest a retrosternal mass of 4 x 1.7 cm was detected with contrast enhancement. Resection of the tumor and thymus gland demonstrated a choriocarcinoma in part adjacent to the thymus and in part in the thymus. Postoperative beta-HCG levels dropped to 105 IU/L.

Abstract
Choriocarcinoma of testes is a very rare tumor with poor prognosis, usually presenting with high serum level of human chorionic gonadotropin (hCG>50,000 mIU/ml) and advanced hematogenous metastases. Data with salvage chemotherapy has been sparse, with few long-term survivors. Between April 1996 and October 2004, 184 patients with germ cell tumor were treated at Indiana University with salvage high-dose chemotherapy (HDCT) with autologous peripheral blood stem cell transplant. Thirteen had pure choriocarcinoma or choriocarcinoma syndrome (normal testes by palpation and ultrasound, normal serum alpha-fetoprotein, advanced hematogenous metastases and high level hCG). All patients had progressed following one or two lines of cisplatin combination therapy. HDCT regimen was carboplatin 700 mg/m(2) and etoposide 750 mg/m(2) intravenously given for 3 consecutive days. A second course was given after hematopoietic recovery, usually 3-4 weeks later. The median survival was 19 months (range 5-90). Six patients (46%) are alive and continuously disease free (cNED) at a median follow-up of 37 months (range 19-75). One additional patient who relapsed after HDCT and was treated with third line chemotherapy followed by two surgical resections of choriocarcinoma is currently alive NED at +90 months from HDCT. Long-term disease-free survival and potential cure is possible with HDCT in choriocarcinoma patients that progressed after standard cisplatin combination therapy.

Abstract
BACKGROUND The imaging methods proposed by the International Consensus for the Diagnosis of Metastases in Trophoblastic Neoplasia are sufficient to stage the disease in most cases. However, there are 2 circumstances in which a more accurate imaging method is necessary: condemonstrate tl fusing images in conventional studies and persistent low 18 FDG-PET/CT human chorionic gonadotropin (hCG) values. Eighteen-fluoro-2-deoxyglucose-positron emission tomography/ computed tomography (18 FDG-PET/CT) can be helpful in these cases. CASES Case 1. A 51-year-old woman was referred to the Hospital Universitario de Caracas from another hospital with a diagnosis of cervical adenosquamous carcinoma. She complained of vaginal bleeding; clinical and sonographic evaluation demonstrated a tumor in the uterus and lower third of the vagina. A new histopathologic study was performed, and choriocarcinoma (CC) was diagnosed and staged as International Federation of Gynecologists and Obstetricians (FIGO) II:12 The im aging studies were confusing, so an 18 FDG-PET/CT was performed, showing multiple nodules in the lungs. Case 2. A 25-year-old woman was admitted with symptoms that mimicked those of ectopic pregnancy; a left salpingectomy was performed, with a histopathologic report of CC. It was classified as FIGO stage 11:4. Treatment consisted of chemotherapy, hysterectomy and 1 pelvic tumor resection. Two years after discontinuing therapy, persistent low hCG values were detected without evident metastatic disease demonstrated by CT. Eighteen FDG-PET/CT showed multiple pulmonary nodules. CONCLUSION Eighteen FDG-PET/CT seems to reveal metastases that are either confusing or not detected by other imaging techniques currently accepted in most gestational trophoblastic neoplasia protocols.
