Ovarian carcinoma associated with endometriosis.

OBJECTIVES Previous studies have suggested an association between endometriosis and development of ovarian cancer. A study was performed to evaluate the cases of ovarian carcinoma associated with endometriosis. STUDY DESIGN The study includes patients with ovarian carcinoma associated with endometriosis diagnosed between 2000 and 2010 at Hacettepe University Hospital, Ankara, Turkey. A total of 1086 patients who underwent surgical staging for ovarian carcinoma were analyzed retrospectively for the presence of histologically documented endometriosis. The clinical and pathological characteristics of 45 ovarian carcinoma patients associated with endometriosis were evaluated including histologic subtype, stage and grade. RESULTS Ovarian carcinoma was found to be associated with endometriosis in 4.1% (45/1086) of the cases. Of them, 17 patients (37.8%) had clear cell, 15 (33.3%) had endometrioid, 6 (13.3%) had serous papillary, 4 (8.9%) had mucinous and the remaining 3 patients had an undifferentiated subtype of ovarian carcinoma. Twenty-three (51.1%) patients had stage I, 4 (8.9%) had stage II and 18 (40.0%) had stage III disease. The frequency of coexistence of endometriosis was 20.4% (17/83) for clear cell carcinoma and 9.3% (15/161) for endometrioid cell carcinoma. CONCLUSIONS Only a small proportion of ovarian cancer cases were found to be associated with endometriosis. Endometriosis was most frequently associated with clear cell and endometrioid types of ovarian carcinoma. Ovarian carcinoma associated with endometriosis seems to represent a distinct disease entity with different histological subtypes, early presentation and a relatively favorable outcome.

Steroid Cell Tumor of the Ovary in an Adolescent: A Rare Case Report

Steroid cell tumors (SCTs) of the ovary are a rare subgroup of sex cord tumors, account for less than 0.1% of all ovarian tumors, and also will present at any age. These tumors can produce steroids, especially testosterone, and may give symptoms like hirsutism, hair loss, amenorrhea, or oligomenorrhea. For the evaluation of androgen excess, testosterone and dehydroepiandrosterone sulfate (DHEA-S) are the first laboratory tests to be measured. A pelvic ultrasound and a magnetic resonance imaging are useful radiologic imaging techniques. Although steroid cell tumors are generally benign, there is a risk of malignant transformation and clinical malignant formation. Surgery is the most important and hallmark treatment.

Pregnancy outcome of five patients with renal amyloidosis regarding familial Mediterranean fever.

Abstract Familial Mediterranean fever (FMF) is an autosomal recessive disease affecting mainly patients of the Mediterranean basin and its major complication is the development of renal AA amyloidosis. On the other hand pregnancy with amyloidosis is not common; nevertheless, amyloidosis will complicate pregnancies also with the underlying disease and may cause terrible perinatal morbidities and mortalities. We report here the cases of five pregnant women and their pregnancy outcomes, who have been diagnosed with FMF complicated by renal amyloidosis. In the five cases, we observed that increased pregnancy complication such as small for gestational age, intrauterine growth restriction, preeclampsia and preterm birth.

Tuboovarian Abscess due to Colonic Diverticulitis in a Virgin Patient with Morbid Obesity: A Case Report.

Since tuboovarian abscess is almost always a complication of pelvic inflammatory disease, it is rarely observed in virgins. A 30-year-old virgin patient presented with pelvic pain, fever, and vaginal spotting for the previous three weeks. Her abdominopelvic computed tomography scan revealed bilateral multiseptated cystic masses with prominent air-fluid levels suggesting tuboovarian abscesses. The sigmoid colon was lying between two tuboovarian masses, and its borders could not be distinguished from the ovaries. The patient was presumed to have bilateral tuboovarian abscesses which developed as a complication of the sigmoid diverticulitis. She was administered intravenous antibiotic therapy followed by percutaneous drainage under ultrasonographic guidance. She was discharged on the twenty second day with prominent clinical and radiological improvement. Diverticulitis may be a reason for development of tuboovarian abscess in a virgin patient. Early recognition of the condition with percutaneous drainage in addition to antibiotic therapy helps to have an uncomplicated recovery.

Adnexal masses in women with breast cancer

Adnexal masses detected in breast cancer survivors are of particular concern because of the increased risk of ovarian malignancy.

Recurrence of endometriosis; risk factors, mechanisms and biomarkers; review of the literature.

Endometriosis has a wide clinical spectrum and induces a chronic inflammatory process. The incidence of endometriosis in women with dysmenorrhoea is up to 40-60%, whereas in women with subfertility is up to 20-30%. Recurrence of endometriosis varies greatly among different studies. The overall recurrence rates range between 6 to 67% according to the criteria that are taken into consideration. Which of the various reasons is more predictive for recurrence is still unclear and controversial. The main aim of post-operative medical treatment is suppressing ovarian activity leading to atrophy of endometriotic lesions. The success of treatment depends on the resorption of all residual visible lesions and the eradication of microscopic implants. The recurrent lesions might originate from residual lesions or from de novo cells. Determining risk factors for recurrence may allow the identification of subgroups at risk for disease control. Potential biomarkers for recurrence could also maintain targeted therapy.

Two patients with marginal symptoms showing hyperthecosis at the edge of malignancy: Presentation of two cases

It is important to define the aetiology of increased levels of androgens in women. Ovarian stromal hyperplasia (OSH) and ovarian hyperthecosis (OHT) are non-neoplastic pathologies. They show the excess of androgen production and have a wide clinical range like hirsutism, virilisation, abnormal menses, obesity, hypertension and insulin resistance. Ovarian stromal hyperplasia and hyperthecosis are commonly seen in postmenopausal women and generally involve both ovaries. Laboratory testing is the gateway; testosterone and dehydroepiandrosterone sulphate (DHEA-S) are the first hormones that should be measured. OSH and OHT could also be a reason for endometrial malignancy by unopposed oestrogenic status. Hyperthecosis must be differentiated from several other diseases, especially malignant conditions, and the treatment for postmenopausal women should be bilateral oophorectomy.

Giant Abdominopelvic Haematoma Arising from Ovulation in a Glanzmann’s Thrombasthenia Patient with Platelet Refractoriness: Treatment with Surgery and Intra-Abdominal Tranexamic Acid

Glanzmann’s thrombasthenia (GT) is a very rare autosomal recessive genetic bleeding disorder. Women with coagulation abnormalities are at increased risk of corpus luteum rupture and haemoperitoneum. Here we present a severe case of GT resulting in a haematoma extending from the pelvis to the liver that could only be controlled by surgery and intra-abdominal tranexamic acid.

In vitro chemosensitivity in ovarian carcinoma: Comparison of three leading assays.

OBJECTIVE An alternative approach to the current therapy of ovarian carcinoma is the individualization of treatment by determining the sensitivity of tumoral tissue to chemotherapeutic agents before the initiation of chemotherapy. The objectives of the study are to determine the efficacy of in vitro chemosensitivity assays in ovarian carcinoma and to measure the correlation of three leading assays. MATERIAL AND METHODS Fresh tumoral tissue samples of 26 newly diagnosed primary ovarian cancer patients were studied with 3-(4,5-dimeth-ylthiazol-2-yl)-2,5-diphenyltetrazolyum bromide (MTT) assay, adenosine triphosphate-tumor chemosensitivity assay (ATP-TCA) and differential staining cytotoxicity (DISC) assays. Chemosensitivity of tumors were studied for paclitaxel, carboplatin, docetaxel, topotecan, gemcitabine, and doxorubicin with each of the three assays. Subgroup analysis was performed for stage, grade, and histologic type. RESULTS The in vitro chemosensitivity results of MTT, ATP, and DISC assays were found to be similar. The subgroups in which in vitro assays would be more useful were encountered for patients with advanced stage and serous histology ovarian carcinoma. CONCLUSIONS In vitro chemosensitivity can be determined in ovarian carcinoma with ATP, MTT, or DISC assays before the initiation of chemotherapy. These three assays correlate well with each other and are particularly useful for serous and advanced cancers. Large prospective studies comparing standard versus assay-directed therapy with an endpoint of overall survival are required before routine clinical utilization of these assays.

Evaluation of the relation between preapoptotic sperm rate in ejaculate and intrauterine insemination success rate in patients with unexplained infertility.

abstract The parameters measured in the standard semen analysis may be insufficient for exact differentiation between fertile and infertile men. Therefore, we assume that the high rate of apoptotic sperm in ejaculate may play a role on the aetiology of unexplained infertility. Couples with unexplained infertility treated by ovulation induction and intrauterine insemination were consecutively enrolled (n = 94). To determine the proapoptotic sperm rate, the ejaculate from patients was stained with annexin V. Thirteen of the 94 couples (13.8%) conceived after intrauterine insemination. The annexin V-positive sperm rate was found to be 20.0% in the whole group. In women failing to conceive, the annexin V-positive sperm rate was 20.8% compared to 15.7% in patients who achieved pregnancy. Although there is a trend towards higher preapoptotic sperm rate in couples failing to get pregnant with insemination, the difference did not reach statistical significance.
