1/46. carcinosarcoma of the uterus associated with a nongestational choriocarcinoma.

    choriocarcinoma has been reported in association with endometrial carcinoma and as a metaplastic change in multiple carcinomas, including liver, urinary bladder, lung, and the gastrointestinal tract. We report choriocarcinoma in conjunction with a carcinosarcoma (also called malignant mullerian mixed tumor) in a 71-year-old woman whose hysterectomy specimen revealed two polypoid lesions of the endometrium, one arising from the anterior endometrium and one arising from the posterior endometrium. Histologic examination revealed three histologic patterns. The anterior endometrial lesion showed a FIGO grade 2 endometrioid endometrial adenocarcinoma. The posterior endometrial lesion showed a carcinosarcoma composed of a high-grade adenocarcinoma and scant homologous stromal sarcoma. In addition, a choriocarcinoma was identified intermixed with the adenocarcinoma. The syncytiocytotrophoblasts and cytotrophoblasts stained strongly with 0 human chorionic gonadotropin (beta-hCG) and human placental lactogen (hPL). The patient's beta-hCG levels on postoperative days 14, 27, and 42 were 283, 32, and 7 mIU/mL, respectively. This unusual case suggests the importance of identifying the choriocarcinomatous component, since the serum beta-hCG can serve as a marker of tumor recurrence postoperatively.

2/46. dna polymorphism analysis of a pure non-gestational choriocarcinoma of the ovary: case report.

    A 45-year-old nulligravida woman died from carcinoma peritonitis with choriocarcinoma arising in the ovary. This tumor was resistant to chemotherapy after debulking surgery. dna polymorphism analysis was useful in proving the choriocarcinoma to be non-gestational carcinoma. In this paper, the clinical course and dna polymorphism findings are mainly discussed.

3/46. Ovarian gonadoblastoma with mixed germ cell tumor in a woman with 46, XX karyotype and successful pregnancies.

    An extremely rare case of unilateral gonadoblastoma with mixed germ cell tumor arising in the ovary of a 27-year-old woman with 46,XX karyotype and two successful pregnancies is reported. The mixed germ cell tumor was composed of choriocarcinoma, embryonal carcinoma, yolk sac tumor, immature teratoma and dysgerminoma. The patient has been well, without evidence of disease for over 10 years since her first surgery and adjuvant chemotherapy.

4/46. Primary choriocarcinoma of the ovary. Report of two cases.

    Primary choriocarcinoma of the ovary (PCO) is rare. This can be gestational (GCO) or nongestational (NGCO) in origin. It is difficult to differentiate between CGO and NGCO. NGCO carries a worse prognosis than GCO. We present two cases of metastatic GCO who were treated successfully with combination chemotherapy and are alive and disease free at the time of reporting.

5/46. Nongestational pure ovarian choriocarcinoma with contralateral teratoma.

    BACKGROUND: Nongestational pure ovarian choriocarcinoma is a rare malignancy with only 29 cases described to date. CASE: We describe a case associated with mature cystic teratoma of the contralateral ovary. Details of all 30 cases including clinical features, associations, surgicopathological findings, operative procedures, postoperative chemotherapy, and outcome are summarized. CONCLUSION: This rare malignancy responds well to surgery and postoperative chemotherapy including the methotrexate-based regimes.

6/46. choriocarcinoma of the ovary associated with mucinous cystadenoma.

    We report choriocarcinoma of the ovary associated with mucinous cystadenoma in a 54-year-old postmenopausal woman, the first reported case of this condition. Doppler ultrasonography, computed tomography, and magnetic resonance imaging showed hypervascularity of the tumor that corresponded to the area of choriocarcinoma within the multilocular cyst. The patient exhibited multiple pulmonary metastases and died of intracerebral hemorrhage.

7/46. Ovarian mixed germ cell tumor with predominance of polyembryoma: a case report with literature review.

    An ovarian mixed germ cell tumor in a 34-year-old woman contained a predominant component of polyembryoma as well as foci of choriocarcinoma, yolk sac tumor, and immature teratoma. No previous cases of identical composition have been found in the literature.

8/46. Pure non-gestational choriocarcinoma of ovary a case report with autopsy findings.

    Primary choriocarcinoma of the ovary (PCO) is rare. This can be gestational (GCO) or non-gestational (NGCO) in origin. It is difficult to differentiate between CGO and NGCO. Non-gestational choriocarcinoma carries a bad prognosis than GCO. We present a case of NGCO who had pulmonary metastasis.

9/46. Co-existent ovarian mucinous cystadenocarcinoma and ovarian choriocarcinoma.

    We present the case of a 63-year-old woman with an ovarian neoplasm in which mucinous cystadenocarcinoma and choriocarcinoma coexisted. blood levels of beta-hCG were elevated and bilateral ovarian stromal luteinization was seen. The rarity of this association and its clinical and pathologic implications are discussed.

10/46. Monodermal highly specialized teratoma of the ovary: a sebaceous gland tumor.

    Teratomas are neoplasms that originate in pluripotential cells and contain representations of all three germ layers in a rather mature state. Specialized forms of teratoma with unilateral development of certain tissues, such as struma ovarii, argentaffin tumors, cholesteatoma, primary choriocarcinoma of the ovary, pseudomucinous cystoma and neurogenic cysts are known. In this paper we describe an ovarian teratoma consisting entirely of sebaceous glands.
