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

STUDY OBJECTIVE: To investigate clinical features and biologic behavior of ovarian cancer that might be closely related to endometrioma and/or endometriosis. DESIGN: Retrospective study (Canadian Task Force classification II-2). SETTING: University hospital. PATIENTS: All 324 women who were operated for endometriomas and/or ovarian tumors 5 cm or greater in diameter between January 1988 and December 1997. INTERVENTION: One hundred twelve women underwent laparoscopic surgery and 212 had laparotomy. MEASUREMENTS AND MAIN RESULTS: All tissues were evaluated histologically. Clinical examinations including ultrasound and serum tumor makers were performed in all patients preoperatively. No malignancies were found at laparoscopic surgery (76 endometriomas, 36 ovarian tumors). The frequency of endometriosis in benign, borderline malignant, and malignant tumors was 9.7%, 12.5%, and 11.4%, respectively. Endometriosis was present most frequently (40%) in women with endometrioid adenocarcinoma. It was present in 81 patients with endometriomas and 25 with ovarian neoplasms. Of these, nine women (8.5%) had malignant tumors, including borderline malignancy. Among patients with malignant tumors, those without endometriosis were significantly older (mean +/- SD age 54.9 +/- 16.2 yrs) than those with endometriosis elsewhere in the pelvis (45.9 +/- 8.9 yrs). CONCLUSION: Endometriosis may be closely related to ovarian tumors such as endometrioid adenocarcinoma. Surgeons should be aware of this possibility, and candidates for laparoscopic surgery should be carefully selected based on preoperative evaluations. 相似文献

BACKGROUND: The use of gonadotrophin-releasing hormone agonist and purified follicular stimulating hormone increases the incidence of ovarian cysts during in vitro fertilization-embryo transfer cycles. The aetiopathogenesis and the effects of ovarian cysts on controlled ovarian hyperstimulation is unclear; most authors observed no-detrimental influence of ovarian cysts in controlled ovarian hyperstimulation cycles for IVF. The aim of this study was the evaluation of the real incidence and effects of ovarian cysts during in vitro fertilization-embryo transfer cycles. METHODS: Design: retrospective study. Setting: reproductive medicine units. Patients: 130 women. Interventions: r-FSH--225 U.I. was administered to 130 women i.m. after a long protocol of down regulation with GnRH-a (Triptoreline 3.75). The drug administration was personalized on the basis of: pre-existent patients pathologies; E2 blood levels; ultrasound evaluation of the follicular development. Main outcome measures: E2 levels, number and quality of oocytes retrieved, fertilization rate, number of embryos developed, pregnancy rate. RESULTS: At the end of stimulation ovarian cyst was observed in eighteen cases. There was no difference, between the cycles with or without cysts, in the follicular development, number and quality of eggs retrieved, fertilization rate, number and quality of the transferred embryos, pregnancy and miscarriage rate. CONCLUSIONS: The conclusion is drawn that the incidence of ovarian cysts during COH can be reduced observing some simple rules like: to exclude from the stimulation protocols patients with follicles of more than 12 mm diameters as observed at the preliminary ultrasound control; to personalize the therapeutic regime with the pre-existent patients pathologies; ultrasound evaluation of the follicular development; determination of the E2 serum levels, every two days. 相似文献

原发性卵巢功能不全与卵巢早衰的病因学研究进展 总被引:4,自引:0,他引:4
目前,卵巢早衰(premature ovarian failure,POF)是被广泛接受和应用的专业术语,通常是指女性40岁之前闭经,伴有高卵泡刺激素(FSH)和低雌激素水平.由于临床治疗很棘手,如何预防和预测POF的发生风险,成为临床医生关注的焦点.尽管在POF发病机制的探讨中,染色体结构或数目异常、自身免疫功能、医源性及环境等相关因素与POF发病的相关性研究已取得很大进展,但仍有部分POF患者的病因不清,称为"特发性POF". 相似文献

OBJECTIVE: To evaluate the benefits associated with routine uterine curettage following complete second trimester termination of pregnancy by extraovular prostaglandin E2. STUDY DESIGN: Fifty-five patients between 15 and 24 weeks' gestation who had undergone complete termination of pregnancy by continuous extraovular instillation of prostaglandin E2 (PGE2), were randomly assigned into either no further intervention (n=25), or uterine curettage under general anesthesia (n=30). The need for late uterine curettage, clinical and ultrasonographic parameters at 1 and 42 days follow-up, as well as the incidence of the minor and major complications, were compared between groups. RESULTS: Baseline and post-abortion clinical and ultrasonographic characteristics were similar in both groups. Mean (+/- Standard error of the mean) number of post-abortion bleeding days in the curettage group was 8.9+/-1.8 versus 10.1+/-2.6 days in the non-curettage group (P=NS). No patient in the former group, compared to three patients in the latter group, needed late uterine curettage, (P=NS). Major and minor complications rates in the curettage and in the no-curettage groups were not significantly different. Considerably more patients in the curettage group needed analgesic agents following the abortion compared to the no-curettage group (60% vs. 3.3%, respectively; P<0.001). CONCLUSIONS: Routine uterine curettage in patients undergoing complete second trimester termination of pregnancy by extraovular instillation of PGE2, exerts no benefit. 相似文献

Adenomyoma is a benign tumor composed of smooth muscle and benign endometrium. These tumors typically originate within the uterus. An extrauterine adenomyoma is an extremely rare entity. After an extensive literature search, only four cases of primary ovarian adenomyoma appear to have thus far been reported. Here, we report a case of ovarian adenomyoma in a 39-year-old woman mimicking malignant neoplasma of the ovary, along with a brief literature review. 相似文献

辅助生殖技术(ART)的成功率依赖于正确的卵巢刺激方案,而卵巢刺激方案的决定依靠准确的卵巢储备功能和卵巢反应性的评估,主要包括年龄、基础性激素水平、基础窦卵泡数(AFC)、抗苗勒管激素(AMH)等,但是目前尚无能够独立评价卵巢储备功能和卵巢反应性的特异性标志物,仍需联合应用评估。 相似文献

Twenty-seven patients with ovarian cancer underwent unilateral salpingo-oophorectomy and were followed for 12-215 months (mean 80) after completion of therapy. Of these, nine patients who received pelvic irradiation subsequently developed ovarian failure. Of the remaining 18 patients who maintained ovarian function, 13 (72%) developed a functional ovarian cyst during the follow-up period. Of these 13 patients, eight were observed until the functional cyst regressed, four were treated with oral contraceptives (OCs) to suppress ovarian function, and one underwent oophorectomy for a large corpus luteum cyst. We recommend that OC pills be considered for suppression of ovarian function in postmenarcheal girls after completion of therapy for ovarian neoplasms. Routine use of OCs may simplify the follow-up of these patients by preventing the formation of functional ovarian cysts. In postmenarcheal patients not treated with OCs, the finding of a unilocular ovarian cyst should be considered to represent a functional cyst, and a trial of OCs for 3 months may result in spontaneous regression. Persistent cysts must be operatively removed. 相似文献

Summary Differential diagnosis is a major problem in histopathology of ovarian tumors. Difficulties may arise if the tumor is a poorly
differentiated carcinoma or a granulosa cell tumor of the sarcomatoid type. It was the aim of the present study to evaluate
the usefulness of immunohistochemistry in differentiating between granulosa cell tumors of the ovary and ovarian carcinomas.
We investigated 56 ovarian malignancies (13 granulosa cell tumors, 17 serous, 14 mucinous and 12 poorly differentiated carcinomas)
and performed immunohistochemical detection of Vimentin, Keratin, CA125, CA19-9, CEA, S100 and Ber-EP4. Expression of Vimentin
was highest and expression of Keratin was lowest in granulosa cell tumors in contrast to carcinomas. CA125 and CA19-9 were
not expressed in granulosa cell tumors, whereas the detection rate in carcinomas (except for CA125 in mucinous carcinomas)
was high. CEA, S100 and Ber-EP4 do not seem to be useful markers in differential diagnosis. A marker profile of Vimentin,
Keratin, CA125 and CA19-9 allows a quite strict differentiation between poorly differentiated ovarian carcinomas and granulosa
cell tumors of the ovary. 相似文献

Objective
To compare the long term impact on ovarian reserve between laparoscopic ovarian cystectomy with bipolar electrocoagulation and laparotomic cystectomy with suturing for ovarian endometrotic cyst.Patient and method(s)
121 patients with benign ovarian endometroitic cysts were randomised to either laparoscopic ovarian cystectomy using bipolar electrocoagulation (61 patients) or laparotomic ovarian cystectomy using sutures (60 patients). Serum follicle-stimulating hormone, Antimullerian hormon, Basal antral follicle Count, mean ovarian diameter, and ovarian stromal blood flow velocity were measured at 6, 12 and 18 months after surgery and compared in both groups.Result(s)
A statistically significant increase of serum FSH was found in the laproscopic bipolar group at 6-, 12 and 18-month postoperativly compared to open laparotomy suture group. Also, a statistically significant decrease of the mean AMH value occurred in laproscopic bipolar group at 6-, 12 and 18-month follow- up compared to open laparotomy suture group. Basal antral follicle number, mean ovarian diameter and peak systolic velocity were significantly decreased during the 6-, 12,18 -month follow-up in laproscopic bipolar group compared to open laparotomy suture group.Conclusion(s)
After laproscopic ovarian cystecomy for endometrioma all pareameter of ovarian reseve are significantly decreased on long term follow up as compared to open laprotomy.18.

Purpose To review the available treatments for women with significantly diminished ovarian reserve and assess the efficacy of different
ovarian stimulation protocols.
Methods Literature research performed among studies that have been published in the Pubmed, in the Scopus Search Machine and in Cohrane
database of systematic reviews.
Results A lack of clear, uniform definition of the poor responders and a lack of large-scale randomized studies make data interpretation
very difficult for precise conclusions. Optimistic data have been presented by the use of high doses of gonadotropins, flare
up Gn RH-a protocol (standard or microdose), stop protocols, luteal onset of Gn RH-a and the short protocol. Natural cycle
or a modified natural cycle seems to be an appropriate strategy. Low dose hCG in the first days of ovarian stimulation has
promising results. Molecular biology tools (mutations, single nucleotide polymorphisms (SNPs)) have been also considered to
assist the management of this group of patients.
Conclusions The ideal stimulation for these patients with diminished ovarian reserve remains a great challenge for the clinician, within
the limits of our pharmaceutical quiver.
Stimulation protocols commonly used for women with significantly diminished ovarian reserve. 相似文献

A 24-year-old single woman was referred to our department due to intermittent abdominal pain. Because her serum CA 125 concentration was extremely elevated an ovarian malignancy was suspected. At the laparoscopic examination, it was determined to be a ruptured endometrioma and serum CA 125 concentrations rapidly decreased after surgery. 相似文献
