The malignant potential of endometrial polyps

OBJECTIVES

To determine the pre-malignant and malignant potential of endometrial polyps and to assess whether different clinical parameters are associated with malignancy in the polyps.

STUDY DESIGN

Four hundred and thirty consecutive cases of hysteroscopic diagnosis of endometrial polyp were retrieved. The medical records, preoperative vaginal sonography results and histopathology findings were reviewed. Statistical analysis was performed.

RESULTS

Hysteroscopy truly identified endometrial polyps in 95.7% of the cases. In 11.4% cases, hyperplasia without atypia was found in the endometrial polyp. In 3.3 and 3.0% of women pre-malignant or malignant conditions were found in the polyp. Older age, menopause status and polyps larger than 1.5 cm were associated with significant pre-malignant or malignant changes, although the positive predictive value for malignancy was low. All the malignant polyps were diagnosed only in postmenopausal women. The presence of postmenopausal or irregular vaginal bleeding, was not a predictor of malignancy in the polyp.

CONCLUSIONS

Postmenopausal women with endometrial polyps are at increased risk of malignancy in the polyp. Those patients, whether symptomatic or not should be evaluated by hysteroscopic resection of the polyps. Asymptomatic premenopausal patients with polyps smaller than 1.5 cm can be observed.

Diagnosis and management of malignant germ cell ovarian tumors in young females

Germ cell tumors (GCT) compose most of the preadolescent malignant ovarian tumors; dysgerminoma being the most common (48%), followed by endodermal sinus tumor, immature teratoma, mixed GCT and embryonal carcinoma. The percentage of malignant epithelial ovarian tumors rises with increasing age, while that of the GCT tumors declines. Of all tumor markers discussed, only AFP and hCG are being routinely monitored. Their most effective use is in monitoring response to therapy and detecting recurrences early. The current therapeutic regimens are presented, among them bleomycin, etoposide and platinol (BEP) and other new regimens; their influence on the patients' fertility is discussed. Further improvement in the prognosis of these young patients will hopefully follow development of new surgical and chemotherapeutic approaches.

Ovarian carcinoma during pregnancy: a study of 23 cases in Israel between the years 1960 and 1984

Data from a study on malignant ovarian tumors in pregnancy in Israel are presented. During the 25-year period of the survey, 23 new cases of malignant ovarian tumors during pregnancy were diagnosed, representing an incidence of 0.12/100,000 females over the age of 14; over half of the patients were in their third decade of life at the time of diagnosis of the tumor. Ovarian malignant tumors during pregnancy are more prevalent in Jewish women of European-American origin than in those of Asian-African descent. Borderline carcinomas were found in 35% of our patients; epithelial invasive tumors were found in 30%; the other tumors were dysgerminoma (17%), granulosa cell tumor (13%), and undifferentiated carcinoma (5%). Most of the patients (74%) were diagnosed in stage I. In three cases, ovarian cancer was diagnosed during surgery for tubal pregnancy, and in two during cesarean section at term. In early-stage disease and low-potential-malignancy tumors, surgery can be conservative; thus, 14 of 23 bore a live child. In advanced disease, aggressive surgery, chemotherapy, and/or radiotherapy should be instituted. Factors affecting prognosis were age of patient, histologic type of tumor, and clinical stage of disease. Overall, the survival is much better than that for ovarian tumors in general, because most of the tumors are of low potential malignancy and are diagnosed at an early stage.

Immunocytochemical study of an endometrial diffuse clear cell stromal sarcoma and other endometrial stromal sarcomas

Intermediate filament composition was studied in the following endometrial stromal tumors: low-grade stromal sarcoma (endolymphatic stromal myosis), high-grade stromal sarcoma with an associated adenocarcinoma (collision tumor), diffuse clear cell stromal sarcoma and a mesodermal mixed tumor (carcinosarcoma). The tumor cells of the stromal tumors as well as the mesenchymal elements of the mixed mesodermal tumor were decorated exclusively with antibodies to vimentin. Desmin was not demonstrated in these tumor cells. A biochemical study of the cytoskeletal filaments present in the low-grade stromal sarcoma revealed, in addition to vimentin, beta and gamma actin as seen in normal endometrial stroma. Cytokeratins were only identified in epithelial components which were present in some of these tumors. Intermediate filament typing in these endometrial neoplasms contributes to the elucidation of histogenetic problems, may delineate mesenchymal from epithelial elements, may separate muscle from stromal lesions and in one instance helped to define a hitherto unreported diffuse clear cell stromal sarcoma.

Spontaneous ovarian hyperstimulation syndrome concomitant with spontaneous pregnancy in a woman with polycystic ovary disease

Ovarian hyperstimulation syndrome has been described after treatment with exogenous gonadotropins, clomiphene citrate, and gonadotropin-releasing hormone. Spontaneous ovarian hyperstimulation syndrome has not been described before, except in association with hypothyroidism. We report on a case associated with spontaneous pregnancy, occurring in a woman with polycystic ovary disease.

Twin pregnancy consisting of a complete hydatidiform mole and co-existent fetus: Report of two cases and review of literature

Hydatidiform mole with co-existing live fetus is a rare entity. Two cases are reported. In the first, complete mole with a co-existing live fetus was suspected on ultrasound examination at 16 weeks of gestation. A termination of pregnancy was performed due to early onset of severe preeclampsia and thyrotoxicosis. In the second case, the patient was admitted at 26 weeks of gestation due to preeclampsia. Genetic amniocentesis at 19 weeks of gestation revealed a normal 46 XX karyotype. Ultrasound examination at 21 weeks of gestation demonstrated two cystic lesions in the fetal liver, wide multicystic placenta and polyhydramnious. Following deteriorating severe preeclampsia, a live female infant (730 g) along with a huge placenta (1350 g) was delivered by a cesarean section. Unfortunately, the newborn died after 35 days. Pathological examination in both cases was consistent with a complete mole co-existing with a viable fetus. During a 1 year follow up period, there was no evidence of persistent or metastatic disease in both cases. Review of literature discussing the diagnostic tools, clinical features, management and outcome of pregnancies with complete mole with a co-existing live fetus is presented.

A multicenter study of CA 125 level as a predictor of non-optimal primary cytoreduction of advanced epithelial ovarian cancer

AIMS

To provide a large database of pre-operative CA 125 levels which may predict inappropriate cytoreductive surgery in patients with advanced epithelial ovarian cancer.

METHODS

A multicenter review of the records of 424 patients with FIGO stage III and IV epithelial ovarian cancer of patients who underwent primary cytoreductive surgery was performed. The validity of pre-operative CA 125 level measurement as a single predictor of the possibility to achieve only suboptimal cytoreduction was evaluated by calculating the sensitivity and the specificity of various cut-off values. The relative importance of different cut-off values in achieving the best predictive validity was assessed by a receiver operating characteristics (ROC) curve.

RESULTS

Optimal cytoreduction (largest diameter of residual tumour < or =1 cm) was achieved in 242 patients. The median CA 125 level in optimally cytoreduced patients was lower than in those patients suboptimally debulked (304 vs 863 U/mL; p<0.001). The area under the ROC curve was 0.65 (95% confidence interval, 0.60-0.71) and the CA 125 threshold derived from the ROC was 400 U/mL. The accuracy of the test at this level was 62%.

CONCLUSIONS

The clinical applicability of the ROC derived CA 125 threshold is limited. The data accrued in the study provides a basis for decision-making regarding the place of primary surgery various CA 125 levels.

Localization of estrogen receptors in long bones and vertebrae of human fetuses

In order to investigate the possible role of estrogen in the development of cartilage and bone we studied by immunofluorescence immunohistochemistry and autoradiography 26 human embryos and fetuses 7-22 weeks in gestational age associated with pregnancy interrupted for non-medical reasons. In order to demonstrate the presence of estrogen receptors (ERs) in human fetal cartilage, cryostat sections of long bones and lumbar and thoracic vertebrae were prepared for (1) fluorescent immunocytochemistry using an antiidiotypic monoclonal antibody to anti-estradiol receptor monoclonal Ab labeled with fluorescein isothiocyanate (FITC), (2) immunohistochemistry using monoclonal antihuman estradiol receptor antibody, labeled with strept. A-B immunoperoxidase, and (3) autoradiographic localization of estradiol using labeled (3H) 17 beta estradiol. In fetuses aged 10 weeks or older, intranuclear and perinuclear localization of ER was demonstrated by all methods, mainly amongst chondrocytes of the proliferating and higher hypertrophic zones of the epiphyses and in the cartilage of vertebral bodies. These data suggest that estrogen acts directly on chondrocytes of human fetuses through an ER-mediated mechanism.

Conservative treatment of adenocarcinoma of the endometrium in young patients. Is it appropriate?

Few reports have suggested that nulliparous young patients with endometrial cancer may be treated conservatively to preserve fertility. We present a young nulliparous woman with a well differentiated adenocarcinoma of the endometrium treated with progestins. Since she did not respond, a definite operation was performed revealing involvement of the uterine isthmus, thus necessitating adjuvant radiotherapy.

Basal cell carcinoma of the vulva

BACKGROUND AND OBJECTIVES

Vulvar basal cell carcinoma (BCC) accounts for 7% of all vulvar cancers at two hospitals in the south of Israel. The purpose of this study was to investigate the clinical findings, treatment and outcome of patients with vulvar BCC treated at these institutions.

METHODS

Data from the files of eight patients with vulvar BCC who were managed at two regional hospitals in the south of Israel (Soroka Medical Center, Beer-Sheva and Kaplan Hospital, Rehovot) between January 1961 and December 1997 were evaluated.

RESULTS

Mean age at diagnosis was 70.5 years. A history of other primary cancers was encountered in two patients. Prevailing presenting symptoms were vulvar lump, ulcer, itching, and bleeding. The tumor was most often located on the labium major and its mean size was 2.25 cm. Six patients had wide local excision, one had excisional biopsy, and one had hemivulvectomy. Two patients developed local recurrence and were treated by wide local reexcision and hemivulvectomy, respectively. At follow-up, no patient developed regional and/or distant metastases, or died of BCC.

CONCLUSIONS

Vulvar BCC is characterized by an indolent behavior with a very low propensity for metastatic spread. The treatment of choice is wide local excision. Because of a substantial risk of local recurrence and high frequency of other primary cancers, close long-term follow-up is essential.

Ovarian mucinous cystadenocarcinoma with mural nodule of carcinomatous derivation. A light and electron microscopic study

A case of an ovarian mucinous tumor with a mural nodule is reported. The epithelial elements consisted of benign, low malignant potential, and invasive mucinous carcinoma. The latter was present in one focus near the surface of the mural nodule as well as in some shallow depressed areas in the cyst wall. The nodule itself was made up of highly malignant, anaplastic cells which on light microscopic examination showed some similarities to the cells previously described in the sarcomatous and in some of the sarcoma-like mural nodules. However, analysis of light microscopic features in our case showed continuity and histologic similarities between the malignant mucinous cells and the sarcoma-appearing elements in the mural nodule. Ultrastructural features also supported an epithelial origin of the cells within the mural nodule. This case is the first of its kind with light and electronmicroscopic documentation and supports an epithelial origin for some of the mural nodules in ovarian mucinous tumors.

Sertoli cell tumor causing precocious puberty in a girl with Peutz-Jeghers syndrome

Distinctive ovarian and cervical tumors are associated with Peutz-Jeghers syndrome (PJS). The most common gynecological tumors in this syndrome are adenoma malignum of the uterine cervix and ovarian sex cord tumor, particularly sex cord tumor with annular tubules (SCTAT). Other kinds of ovarian tumors have been rarely reported in association of PJS, including Sertoli cell tumors. We report a case of a 4.5-year-old girl with PJS who presented with isosexual precocious puberty (IPP) due to ovarian lipid-rich Sertoli cell tumor. In addition to estrinizing effect of the tumor, the patient had decidual reaction secondary to tumor-derived progesterone secretion. The literature on gonadal tumors in PJS is reviewed, including one previous report of ovarian lipid-rich Sertoli cell tumor associated with this syndrome.

Pneumothorax following induction chemotherapy in patients with lung metastases: a case report and literature review

A 29-year-old patient presented with bilateral pulmonary lesions following surgery for recurrent placental site trophoblastic tumor (PSTT). On day seven after institution of the 'EMA' regimen (etoposide, medium dose methotrexate with folinic acid rescue and actinomycin-D), complete pneumothorax occurred. Closed-system air drainage brought only transient lung expansion and subsequent talc pleurodesis was needed. During follow-up, complete regression of lung metastases was observed. A literature survey of post-chemotherapy pneumothorax in patients with lung metastases disclosed fourteen hitherto reported cases. Including the present PSTT case, non-epithelial gynecologic malignancy (3 patients) ranks second to osteogenic sarcoma (6 cases) with regard to the primary tumor involved.

Epithelial ovarian tumors of borderline malignancy: a study of 50 cases

Of 50 patients with borderline epithelial ovarian tumors, 32 (64%) had serous, 17 (34%) had mucinous and one (2%) had endometrioid tumor. All patients with mucinous tumor had stage I disease, whereas 4 patients with serous tumor had stage II-III disease. Five patients (10%) were pregnant at the time of diagnosis. Seventeen patients (34%) had initial surgery with ovarian conservation and 7 of them were not subjected to further surgery. Five patients (10%) received adjuvant chemotherapy. Five-year survival and 5-year disease-free survival rates were 100% and 96.4%, respectively. It is concluded that for patients with stage IA disease unilateral salpingo-oophorectomy seems to be adequate treatment and for those with more than stage IA disease, surgery should include total abdominal hysterectomy and bilateral salpingo-oophorectomy. Although the effectiveness of chemotherapy in these tumors is uncertain, adjuvant chemotherapy is advocated for patients in whom spread of the tumor beyond the ovaries has occurred.

Palmar fasciitis and polyarthritis associated with ovarian carcinoma in a young patient. A case report and review of the literature

Palmar fasciitis and polyarthritis (PFPA) is an uncommon syndrome characterized by progressive and extensive rheumatic disease. It has usually been associated with neoplasms, most commonly in elderly patients, preceding or accompanying the diagnosis of malignancy. We report a case of a 25-year-old patient with severe deforming PFPA preceding the diagnosis of carcinoma of the ovary. The histopathological findings of diffuse fibrosis, connective tissue proliferation and vasculitis with C3 and IgM deposits in subcutaneous tissue and synovia may further clarify the possible pathogenesis of this unique syndrome.

Urinary retention caused by impaction of leiomyoma in pregnancy

Complete urinary retention caused by incarceration of a retroverted gravid uterus or large fibroid uterus is a rare condition. The following case report illustrates the acute onset of urinary retention caused by the combination of a large leiomyoma and pregnancy. Total hysterectomy was performed. To the best of our knowledge, such a combination has not been reported previously.

Ovarian carcinoma masquerading as ovarian hyperstimulation syndrome

Two patients receiving ovulation-inducing drugs were found to have ovarian carcinoma. Since patients receiving such medication are prone to develop enlarged ovaries with or without the fully developed hyperstimulation syndrome, the diagnosis of ovarian tumors in such patients may be delayed or missed. It is therefore being suggested that an ovarian enlargement persisting for more than 4 weeks, or the finding of ovarian solid masses by sonography in patients receiving ovulation-inducing drugs, should lead to a thorough work-up for neoplasia, sometimes including even laparotomy.

The Role of Laparoscopy in Ovarian Tumors of Low Malignant Potential and Early-Stage Ovarian Cancer

Although it is feasible today to perform laparoscopic surgical staging and treatment of ovarian low malignant potential tumors and early-stage ovarian cancer safely, it is still generally agreed that a patient with ovarian cancer should have a laparotomy. Concerns related to laparoscopy in managing gynecologic malignancy include the accuracy of intraoperative diagnosis, inadequate resection, significance of tumor spillage, improper or delay in surgical staging, delay in therapy, and the possibility of port-site metastasis. On the other hand, laparoscopy has the advantages of being a minimally invasive surgery, with shorter hospitalization, decreased postoperative pain, and quicker return to normal daily activities. We review the current literature discussing the consequences of laparoscopic surgery in ovarian tumors of low malignant potential and early-stage ovarian cancer.

TARGET AUDIENCE

Obstetricians & Gynecologists, Family Physicians.

LEARNING OBJECTIVES

After completion of this article, the reader should be able to list the concerns related to laparoscopic management of ovarian malignancies, to outline the accuracy of the diagnosis of low malignant potential (LMP) ovarian tumors on frozen section, and to summarize the data on the effect of capsule rupture on overall prognosis for patients with ovarian cancer.

Aggressive angiomyxoma of the vulva

A case of aggressive angiomyxoma (AAM) of the vulva is presented. The tumor presented as a slowly growing polypoid mass in the right labium minus near the clitoris. The tumor was treated by wide local excision. The microscopic appearance was that of spindle-shaped neoplastic cells widely separated by a loose myxoid stroma rich in collagen fibers, hyaluronic acid, and prominent irregular-shaped blood vessels. Aggressive angiomyxoma of the vulva must be distinguished from the more common benign and malignant myxoid tumors including myxoma, myxoid liposarcoma, myxoid variant of malignant fibrous histiocytoma, sarcoma botryoides, nerve sheath myxoma, and other soft tissue tumors with secondary myxoid changes. Local recurrence of AAM may be avoided by wide local excision.

Gestational trophoblastic disease following the evacuation of partial hydatidiform mole: a review of 66 cases

OBJECTIVE

The current study was undertaken in order to identify the clinical characteristics and natural history, as well as methods of investigation and available therapy, of persistent gestational trophoblastic disease (GTD) following the evacuation of partial hydatidiform mole (PM).

METHODS

Case reports of persistent GTD following the evacuation of partial mole, were searched using the Medline computerized retrieval system. There were 66 such cases (including 4 cases treated at our department), representing 2.9% of GTD following PM.

RESULTS

The mean age of the women at diagnosis was 28.4 years and mean gravidity was 2.99. The mean gestational age at diagnosis was 15.5 weeks and the mean uterine size was 13.6 weeks. The most common presenting symptom was vaginal bleeding. In the majority of the patients, the pre-evacuation diagnosis was incomplete or missed abortion.

CONCLUSIONS

Although the malignant potential of PM is low, persistent GTD may develop after PM and may even metastasize, it is usually responsive to single agent chemotherapy but may require combination chemotherapy. Therefore, after evacuation of PM, these women should be followed with serial serum b-hCG. Further research is needed to enable earlier identification of PM that eventually will develop persistent GTD.

Ovarian mucinous cystadenoma with leiomyomatous mural nodule

A case of an ovarian mucinous cystadenoma with a leiomyomatous mural nodule is described. The diagnosis was confirmed by immunohistochemical methods. This is the first report of a mural nodule of leiomyomatous nature, thus widening the histologic spectrum that may be encountered in these lesions.

Malignant germ cell tumors of the ovary: a study of 20 cases

In a study of 20 patients diagnosed with malignant ovarian germ cell tumors between 1961 and 1993, clinical and pathologic findings were evaluated. Of the 20 patients, seven (35%) had dysgerminoma, two (10%) endodermal sinus tumor, three (15%) malignant teratoma, one (5%) malignant struma ovarii, one (5%) primary ovarian carcinoid, two (10%) benign teratoma with malignant transformation, and four (20%) combination germ cell tumor. Twelve patients (60%) had stage IA, five (25%) stage IC, and three (15%) stage IIIC. Twelve patients (60%) underwent conservative surgery and eight (40%) had at least bilateral salpingo-oophorectomy. At follow-up, 18 patients (90%) were alive free of disease, one (5%) had died of disease, and one (5%) had died of intercurrent disease. The actuarial 5-year survival rate was 93.3%. It is concluded that for young women who wish to preserve child-bearing capacity, regardless of the stage of the tumor, fertility-preserving surgery with complete surgical staging followed, if necessary by cisplatin-based combination chemotherapy is an appropriate and definitive treatment in the absence of involvement of the contralateral ovary and uterus. For patients in whom child-bearing capacity is not an issue, surgery should include total abdominal hysterectomy and bilateral salpingo-oophorectomy with complete staging, followed if necessary by chemotherapy.

Uterine papillary serous carcinoma: study of 19 cases

OBJECTIVE

Uterine papillary serous carcinoma (UPSC) is an uncommon highly malignant variant of endometrial carcinoma that histologically and clinically resembles ovarian papillary serous carcinoma. The purpose of this study was to present the conjoined experience of two regional hospitals in the south of Israel (Soroka Medical Center, Beer-Sheva and Kaplan Hospital, Rehovot) of handling this tumour.

STUDY DESIGN

Data from the files of 19 patients with UPSC who were managed at these hospitals between July 1991 and June 1997 were evaluated.

RESULTS

The three-year survival rate was 57.3% overall; 83.3% for Stage I and 21.2% for Stages II, III, and IV combined (P<0.02). Eighteen patients had primary surgery which included total abdominal hysterectomy and bilateral salpingo-oophorectomy and 15 (83.3%) of them received postoperative adjuvant therapy which included radiotherapy and/or systemic chemotherapy.

CONCLUSIONS

The prognosis of patients with UPSC is worse than that of patients with other forms of endometrial carcinoma. Primary surgery comprised of total abdominal hysterectomy, bilateral salpingo-oophorectomy and staging is the mainstay of treatment. The type of postoperative treatment is not consistent. By and large, adjuvant pelvic radiotherapy is usually given in early-stage disease and adjuvant systemic chemotherapy is usually prescribed in advanced-stage disease.

Trophoblastic peritoneal implants after laparoscopic treatment of ectopic pregnancy

Persistent trophoblastic activity after salpingostomy for ectopic pregnancy implies the presence of intra-abdominal trophoblastic tissue, usually within the fallopian tube. We report a case of disseminated trophoblastic peritoneal implants, presenting as hemoperitoneum three weeks after laparoscopic salpingectomy. Only 23 such cases have been reported. Surgical treatment of ectopic pregnancy, especially by the laparoscopic technique, may cause intraperitoneal spread and reimplantation of trophoblastic tissue. Precautions for minimizing this complication are discussed.

Lupus-like syndrome in a mother and newborn following administration of hydralazine; a case report

A very-low-birth-weight infant died from pericardial effusion and cardiac tamponade confirmed by the post-mortem findings. The mother suffered from lupus-like syndrome consequent to hydralazine treatment for pregnancy-induced hypertension. The possible relationship between mother-infant pathology and hydralazine administration is discussed.
