Abstract
Various types of human cancer may develop aberrant trophoblastic differentiation, including histological changes and altered expression of β‑human chorionic gonadotropin (β‑hCG). Aberrant trophoblastic differentiation in epithelial cancer is usually associated with poor differentiation, tumor metastasis, unfavorable prognosis and treatment resistance. Since β‑hCG‑targeting vaccines have failed in an early phase II trial, it is crucial to obtain a better understanding of the molecular pathogenesis of trophoblastic differentiation in human cancer. The present review summarizes the clinical and translational research on this topic with the aim of accelerating the development of an effective targeted therapy. Ectopic expression of β‑hCG promotes proliferation, migration, invasion, vasculogenesis and epithelial‑mesenchymal transition (EMT) in vitro, and enhances metastatic and tumorigenic capabilities in vivo. Signaling cascades modulated by β‑hCG include the TGF‑β receptor pathway, EMT‑related pathways, the c‑MET receptor tyrosine kinase and mitogen‑activated protein kinase/ERK pathways, and the SMAD2/4 pathway. Taken together, these findings indicated that TGF‑β receptors, c‑MET and ERK1/2 are potential therapeutic targets. Nevertheless, further investigation on the molecular basis of aberrant trophoblastic differentiation is mandatory to improve the design of precision therapy for this aggressive type of human cancer.

Abstract
Human chorionic gonadotropin (hCG) is a peptide hormone which plays an important role during pregnancy. But its impact is not limited to pregnancy; it also influences tumor formation and metastatic outgrowth, especially in endometrial adenocarcinoma and breast cancer. This review summarizes what has been written in the literature about the role of hCG as a tumor marker in these 2 gynecological malignancies and also about the signal transduction pathways in which hCG is involved. HCG can, on the one hand, be a marker for the progression of a malignant disease, and on the other hand, it may be a point for therapeutical intervention, so further research into this molecule would be very much worthwhile.

Abstract
Somatic endometrial carcinomas with trophoblastic components have only rarely been described. To better characterize this distinctive combination of histotypes, we report herein 4 new cases, representing the largest cohort reported thus far, and review previously reported cases. The 4 new patients ranged in age from 61 to 77 yr (mean, 68 yr). The first patient had a grade 2 endometrioid carcinoma, surgical International Federation of Gynecology and Obstetrics stage IA, that recurred 5 months later at the vaginal apex with purely choriocarcinoma elements, suggestive of unsampled trophoblastic areas in the uterus. The 3 other patients were all International Federation of Gynecology and Obstetrics stage III, and included 2 cases of dedifferentiated endometrial carcinoma with 40% and 20% choriocarcinoma components, and 1 case of grade 1 endometrioid carcinoma with a 40% choriocarcinoma component. Postoperative serum β-human chorionic gonadotropin was elevated in all patients. All received adjuvant combination chemotherapy, but all were dead of disease with distant metastases at an average of 11.75 mo (range, 7-16 mo) after primary staging. Data from our cases were combined with those from 24 cases that had previously been reported in the literature between 1972 and 2016. Analysis of this combined data indicates that endometrial carcinoma with trophoblastic component is a rare neoplasm that occurs primarily in postmenopausal patients. The trophoblastic component is most commonly a choriocarcinoma and the somatic component is most commonly an endometrioid carcinoma or an adenocarcinoma/carcinoma reported without further specification; the somatic component may be a diverse array of histotypes or histotype admixtures. Serum and/or urine β-human chorionic gonadotropin is elevated in almost all patients, and fluctuations of β-human chorionic gonadotropin generally correlated with tumor relapses or recurrences. The stage distribution and patient outcomes in the current and previously reported patients suggests that trophoblastic differentiation usually, but not invariably denotes clinical aggressiveness.

Abstract
Endometrial carcinoma with a germ cell tumor component is a rare event. Here we report a uterine neoplasm with a unique combination of endometrioid adenocarcinoma and mixed germ cell malignant elements. A 28-year-old woman with abnormal vaginal bleeding, an abdominal mass, and elevated alfa-fetoprotein and beta-human chorionic gonadotropin (β-hCG) levels had a history of biopsy of an omental mass and chemotherapy in another hospital one month before her referral to our department. Histologic examination of the mass removed from the omentum revealed an endometrioid adenocarcinoma with yolk sac tumor-like differentiation. Total abdominal hysterectomy, bilateral salpingo-oophorectomy, infracolic omentectomy, and removal of metastatic disease were then undertaken at our hospital. Postoperative chemotherapy was given. Eight months postoperatively, serum alfa-fetoprotein and β-hCG rose again. Cases with primary yolk sac tumors of the endometrium or endometrial carcinoma with trophoblastic differentiation in the literature were reviewed.

Abstract
A choriocarcinomatous component is rarely present in carcinomas of certain sites and few cases of choriocarcinomatous differentiation in endometrioid adenocarcinoma have been reported. The present study reports a case of endometrioid adenocarcinoma of the uterine corpus with choriocarcinomatous differentiation, and discusses the clinicopathological features of this rare tumor. A 59-year-old post-menopausal female presented with abnormal vaginal bleeding. Magnetic resonance imaging demonstrated a relatively well-circumscribed tumor in the uterine corpus and a total cystectomy was subsequently performed. A histopathological examination revealed two distinct components in the uterine corpus tumor. The first component comprised ~80% of the tumor and was composed of poorly-differentiated endometrioid adenocarcinoma. The remaining component consisted of mononucleated and syncytial giant cells containing rich eosinophilic cytoplasm and large pleomorphic nuclei with coarse chromatin. An immunohistochemical analysis revealed that these syncytial giant cells were positive for β-human chorionic gonadotropin (hCG). Therefore, a diagnosis of endometrioid adenocarcinoma with choriocarcinomatous differentiation was confirmed. The clinicopathological features of nine previously reported cases of this tumor were analyzed in addition to the present case. The majority of the patients were post-menopausal. Endometrial choriocarcinoma may be considered to have a highly aggressive clinical course, since nine of the 10 cases displayed metastases and four patients succumbed to the disease. The pathogenesis of the choriocarcinomatous component is not well understood. However, genetic studies have demonstrated that conventional carcinoma and choriocarcinomatous components share common genetic alterations. The choriocarcinomatous component represents aberrant differentiation of the conventional carcinoma, however, genetic analyses of endometrioid adenocarcinoma with choriocarcinomatous differentiation have not been performed.

Abstract
Choriocarcinoma is a unique malignant neoplasm composed of mononuclear cytotrophoblasts and multinucleated syncytiotrophoblasts that produce human chorionic gonadotrophin. Choriocarcinoma can occur after a pregnancy, as a component of germ cell tumors, or in association with a poorly differentiated somatic carcinoma, each with distinct clinical features. Cytogenetic and molecular studies, predominantly on gestational choriocarcinoma, revealed the impact of oncogenes, tumor suppressor genes and imprinting genes on its pathogenesis. The role of stem cells in various types of choriocarcinoma has been studied recently. This review will discuss how such knowledge can enhance our understanding of the pathogenesis of choriocarcinoma, enable exploration of novel anti-choriocarcinoma targeted therapy and possibly improve our insight on embryological and placental development.

BACKGROUND Choriocarcinomas unrelated to pregnancy, teratomas, or germ cell tumors have been found in the stomach, lungs, colon, esophagus, bladder, breast, renal pelvis and other sites. CASE We present a case of a 58-year-old woman with endometrial carcinoma with choriocarcinomatous differentiation. She received surgery and chemotherapy for endometrial adenocarcinoma. However, a metastatic tumor of choriocarcinomatous element appeared at the vaginal cuff 9 months after surgery. Additional chemotherapy for choriocarcinoma resulted in a decrease in the serum hCG and the tumor regressed. Fifty months following surgery, she is alive without disease. CONCLUSION Treatment and follow-up must be performed not only for the adenocarcinoma element but also for the choriocarcinoma element in patients presenting with endometrial carcinoma with choriocarcinomatous differentiation.

Abstract
This article reports a uterine gestational choriocarcinoma arising in a 57-year-old woman with a long latent period of 22 years from the last known pregnancy. Diagnosis was made on an endometrial biopsy specimen, and given the age of the patient, the long latent period, and the limited sample, trophoblastic differentiation within an endometrial carcinoma was considered. The results of DNA polymorphism studies illustrated both paternal and maternal alleles within the tumor in equal amounts, confirming the neoplasm to be gestational in origin and to have originated from a nonmolar gestation. The report discusses the value of DNA polymorphism studies in distinguishing gestational from nongestational choriocarcinoma and from trophoblastic differentiation within a carcinoma.

Abstract
OBJECTIVE An endometrioid adenocarcinoma (EAC) with true trophoblastic differentiation is a rare event with a highly aggressive clinical course. CASE We report an endometrioid adenocarcinoma of the endometrium in which there was a morphologically conventional-appearing EAC component admixed with multinucleated giant cells and large pleomorphic tumor cells that resembled a choriocarcinoma without an elevated serum level of human chorionic gonadotropin (hCG) in a 42-year-old unmarried woman with a history of abnormal uterine bleeding. A total abdominal hysterectomy, bilateral salpingo-oophorectomy, and pelvic lymph node dissection were performed. Histopathologic study of the specimen showed endometrioid adenocarcinoma extended to the deep myometrium with a focus of hemorrhagic and necrotic tumor composed of multinucleated giant cells, large pleomorphic tumor cells, suggesting choriocarcinomatous differentiation (CD). Immunohistochemical studies demonstrated intense reactivity of tumor cells for human chorionic gonadotropin (hCG) confirming the diagnosis. A complete clinical workup ruled out metastatic spread to the brain, lungs, skeleton, or abdomen. The patient was alive with no evidence of disease 6 months later. CONCLUSION Although endometrioid adenocarcinoma with choriocarcinomatous differentiation is known to behave in a more aggressive course, this disease may have a good prognosis with a clinically indolent course when it is small, and without elevated serum hCG levels.

Abstract
Endometrial carcinomas (EnCa) predominantly represent a steroid hormone-driven tumor initiated from prestages. The human endogenous retrovirus HERV-W envelope gene Syncytin-1 was significantly increased at the mRNA and protein levels in EnCa and prestages compared to controls. Steroid hormone treatment of primary EnCa cells and cell lines induced Syncytin-1 due to a new HERV-W estrogen response element and resulted in increased proliferation. Activation of the cAMP-pathway also resulted in Syncytin-1 upregulation, but in contrast to proliferation, classic cell-cell fusions similar to placental syncytiotrophoblasts occurred. Cell-cell fusions were also histologically identified in endometrioid EnCa tumors in vivo. Clonogenic soft agar experiments showed that Syncytin-1 is also involved in anchorage-independent colony growth as well as in colony fusions depending on steroid hormones or cAMP-activation. The posttranscriptional silencing of Syncytin-1 gene expression and a concomitant functional block of induced cell proliferation and cell-cell fusion with siRNAs proved the essential role of Syncytin-1 in these cellular processes. TGF-beta1 and TGF-beta3 were identified as main regulative factors, due to the finding that steroid hormone inducible TGF-beta1 and TGF-beta3 inhibited cell-cell fusion, whereas antibody-mediated TGF-beta neutralization induced cell-cell fusions. These results showed that induced TGF-beta could override Syncytin-1-mediated cell-cell fusions. Interactions between Syncytin-1 and TGF-beta may contribute to the etiology of EnCa progression and also help to clarify the regulation of cell-cell fusions occurring in development and in other syncytial cell tumors.

Abstract
Nongestational choriocarcinomas rarely occur outside the gonads or teratomas. We report a serous carcinoma of the endometrium with a choriocarcinomatous component and review of the literature. A 61-year-old woman underwent hysterectomy and bilateral salpingo-oophorectomy for a serous carcinoma with choriocarcinomatous component. Immunohistochemistry showed a strong p53 staining of the serous component and the cytotrophoblastic cells of the choriocarcinomatous component; the syncytiotrophoblast was negative. The initial serum human chorionic gonadotropin (hCG) was 225,000 IU/L. Postoperatively, the patient developed diffuse pulmonary metastatic disease. Despite chemotherapy, the patient died 2 months after initial diagnosis. Abstracting the data from the reported cases and from the literature, it can be assumed that 2 different tumor types exist. The first one is morphologically and clinically more related to the gestational choriocarcinoma with strongly elevated serum hCG levels, early onset of (distant) metastatic disease, and consecutively rapid and often fatal clinical course. The second type presents as an endometrial carcinoma with single syncytiotrophoblast-like cells, associated with low serum hCG, no distant metastatic disease, and, consequently, a better prognosis. The prognostically relevant component for long-time survival in the latter variant is the nontrophoblastic component.

Abstract
BACKGROUND Nongestational choriocarcinoma, in very rare instances, has been described as a component of other malignancies with a tendency for a very poor prognosis. CASE A 55 year old woman was diagnosed with adenocarcinoma of the cervix, and incompletely treated with only external beam radiation. Adjuvant radical hysterectomy demonstrated no residual tumor, but the patient developed a tumor metastasis mimicking a pulmonary artery thrombus which by histology and immunohistochemistry was pure choriocarcinoma. While chemotherapy was successful in achieving a complete remission, the patient succumbed to complications of her pulmonary metastasis. CONCLUSION Choriocarcinomatous dedifferentiation of cervical adenocarcinoma is extremely rare, with only one other case reported in the literature. While the prognosis for patients with such a tumor is generally poor, aggressive combination chemotherapy may be of benefit in some.

Abstract
We report a case of a primary uterine choriocarcinoma associated with adenocarcinoma occurring during peri-menopausal age, and review the literature. The clinical course and the histopathology of the case were reviewed and a Medline literature search for other cases was performed. BHCG and analysis of uterine curettage provided the diagnosis of choriocarcinoma. Polychemotherapy, started immediately after the patient's clinical condition deteriorated, was successful. Colpohysterectomy and pelvic lymphadenectomy were performed 5 months later. Treatment was completed by vaginal curietherapy. Histopathologic examination of the surgical specimen revealed only adenocarcinoma. The patient was followed for 18 months without evidence of recurrence. The literature search revealed that primary forms are exceptional; the etiology is unknown. Treatment is based on polychemotherapy. Primary choriocarcinomas are rare tumours, associated with other histopathological forms. We document a case occurring during the peri-menopausal period and review the literature on this pathology. The very poor prognosis in the past has changed with early polychemotherapy.

Abstract
This review considers the clinical and pathologic features of the various histologic subtypes of endometrial carcinoma excluding those of pure endometrioid type, as the latter tumors were the subject of a previous contribution in the Journal (Vol. 9, No. 2). Non-endometrioid carcinomas, which account for about 10% of endometrial carcinomas, may pose a great array of problems in differential diagnosis, including their distinction not only from benign lesions but also endometrioid carcinoma and various tumors that may secondarily involve the uterine corpus. The most common subtypes are serous, mucinous, and undifferentiated. Rarer tumors are clear cell, squamous, transitional cell carcinomas, and a variety of poorly differentiated carcinomas with unusual forms of differentiation, such as hepatoid carcinoma, carcinomas with trophoblastic elements, and giant cell carcinoma. Mixed carcinomas, which are common, are also discussed, including those with a component of endometrioid carcinoma. The final section deals with endometrial involvement by metastatic tumors, lesions that, albeit rare, are sometimes neglected in the differential diagnosis of endometrial carcinomas. Important aspects emphasized are: (1) The potential for serous carcinoma to be mimicked by various forms of papillary endometrioid carcinoma. (2) The rarity of clear cell carcinoma and the greater frequency of clear cells in endometrioid carcinoma. (3) The frequency of mucinous epithelium in tumors of mixed cell type. (4) The frequency with which neoplastic mucinous epithelium originates from the endometrium. (5) The striking degree of differentiation of some squamous cell carcinomas. (6) The occasional predominance of non-endometrioid carcinomas (especially serous or undifferentiated carcinoma) within malignant mullerian mixed tumors. (7) The spectrum of reactive epithelial changes and other non-neoplastic abnormalities that may mimic serous or clear cell carcinoma.

Abstract
Most germ cell tumors occur in the gonads or in extragonadal sites in the anatomic midline; this article reviews tumors with similar or identical histologic features that arise in other topographic locations. Such lesions often represent the presence of "germ cell-like" or "germinal" components in what is otherwise recognized as a somatic neoplasm; however, they may also occur in pure form. The morphologic and immunohistochemical features of these proliferations are reviewed, according to the types of germ cell tumors that they recapitulate.

Abstract
OBJECTIVE The purpose of this article is to report a case of coexisting uterine choriocarcinoma and uterine malignant mixed mesodermal tumor (MMMT). The relevant literature is reviewed and possible pathogenesis discussed. METHODS The clinical course and histopathology of the case were reviewed and a Medline literature search for other cases was performed. RESULTS The patient's uterine tumor contained syncytiotrophoblastic and cytotrophoblastic cells that stained positively for the beta subunit of human chorionic gonadotrophin consistent with uterine choriocarcinoma. Pathology also revealed a second distinct neoplasm composed of adenocarcinoma admixed with sarcoma, compatible with a uterine MMMT. The patient experienced metastatic choriocarcinoma to her lungs, lymph nodes, and brain. She suffered a complicated clinical course and died 7 months after her initial diagnosis. The literature search revealed that various gynecologic and nongynecologic carcinomas with trophoblastic differentiation have been described, but an association with uterine MMMT has not been previously reported. CONCLUSIONS Trophoblastic differentiation and choriocarcinoma associated with gynecologic and nongynecologic tumors is rare. We document the presence of uterine MMMT coexisting with uterine choriocarcinoma that followed an aggressive clinical course and review the possible pathogenesis of this lesion.
