1/18. Early prenatal sonographic diagnosis of twin triploid gestation presenting with fetal hydrops and theca-lutein ovarian cysts.The presence of theca-lutein ovarian cysts in the early second trimester of pregnancy is highly suspicious for a complete hydatidiform molar pregnancy but can be seen in association with a partial mole. Theca-lutein cysts may occur following hormonal stimulation for assisted reproductive techniques or in association with multiple gestations. Rare causes include immune and nonimmune fetal hydrops, maternal hypothyroidism, and triploid gestations. We report a case of a monochorionic twin gestation in which prenatal sonography demonstrated multiple anomalies and hydrops in each twin and bilateral theca-lutein ovarian cysts. triploidy in both twins and a partial hydatidiform mole were confirmed at pathologic examination.- - - - - - - - - - ranking = 1keywords = ca- (Clic here for more details about this article) |
2/18. Fetal ovarian cysts: a report of three cases managed by intrauterine aspiration.Small follicular or functional theca-lutein cysts are a common finding in fetal and neonatal ovaries. After delivery, decrease of hormonal stimulation may lead to spontaneous resolution of the cyst. A high rate of complication has been underlined by recent studies, the most common being ovarian torsion with subsequent loss of the ovary. Because torsion may happen with any size of cyst, however large or small, we suggest in utero decompression even in small fetal ovarian cysts (< 5 cm). We report here three cases of such cysts managed by intrauterine aspiration with good outcome and no further need for neonatal surgery. In all cases cytology of the cyst aspirate demonstrated numbers of granulosa cells and fluid biochemistry showed a high amount of estradiol, progesterone, and testosterone that confirmed the etiology as ovarian. Despite the small size of the cysts, no technical difficulties were encountered and no maternal or fetal morbidity occurred. Prenatal management of fetal ovarian cysts remains controversial, however, and our limited experience needs to be assessed on a larger number of cases.- - - - - - - - - - ranking = 0.14285714285714keywords = ca- (Clic here for more details about this article) |
3/18. Two cases of supernumerary ovary: one with large fibroma with Meig's syndrome and the other with endometriosis and cystic change.Reports of supernumerary ovaries are rare. We describe two such cases, one with fibroma and the other with endometriosis and cystic change. A large fibroma measuring 17.4 x 12.0 x 7.5 cm in size was found in the supernumerary ovary of the omentum in the first case of a 47-year-old married woman with Meig's syndrome. The second case was associated with endometriosis and cystic change, measuring 11 x 5 x 3 cm in size and located in the upper abdominal cavity. It was attached to the uterus of a 28-year-old pregnant woman who had neither fibroma nor Meig's syndrome. Histologically, corpus albicans and a few primordial germ cells were demonstrated, respectively. A fibroma showing a storiform pattern was found in the first case. The second case had endometriosis and a thin-walled cyst with bleeding and necrosis caused by torsion. Immunohistochemically, desmin, alpha-smooth muscle actin, c-kit, CA125, Na /K ATPase, overexpression of p53, myc and ras were all negative in the fibroma cells of the first case, and in the endometriosis and cyst wall of the second case. The fibroma cells were positive for vimentin and estrogen receptor, and the proliferating cell nuclear antigen was sporadically demonstrated in their nuclei. The mutation of the p53 gene at exons 5-8 was not detected by sequence analysis. Using RT-PCR, bax, bcl-2 and p16 were not detected either. Clinically, the two cases presented here did not show abnormal hormonal symptoms. They were diagnosed as abdominal tumors or masses. Based on these considerations, one might assume that supernumerary ovaries are probably more frequent than reported at present.- - - - - - - - - - ranking = 0.0012268059143789keywords = antigen (Clic here for more details about this article) |
4/18. Elevated serum CA125 and CA19-9 due to the spontaneous rupture of ovarian endometrioma.A 23-year-old woman was suffered from ruptured ovarian endometrioma with an elevated CA125 and CA19-9 concentration; 9537 and 15,653IU/ml, respectively. Rapid decrease in serum CA125 and CA19-9 was recognized before surgery. Such high levels of both antigens have not been reported in a patient with endometriosis.- - - - - - - - - - ranking = 0.0012268059143789keywords = antigen (Clic here for more details about this article) |
5/18. A true splenic cyst producing carbohydrate antigen 19-9 and cancer antigens 50 and 125, but not interleukin 10.A giant cystic lesion of the left upper abdomen associated with a smaller ovarian cyst in a young female patient is reported. Laboratory data revealed elevated serum levels of carbohydrate antigen 19-9 (CA 19-9), carcino-embryonic antigen (CEA), cancer antigens 50 and 125, and tissue polypeptide antigen. In contrast, the serum levels of interleukin 10, a cytokine involved in modulating immune responses and produced by many cancer histotypes, were normal. Since ovarian cancer or cystic adenocarcinoma of the tail of the pancreas were not ruled out, the patient underwent laparotomy. After splenectomy and ovariectomy, the tumour marker serum levels normalized. histology and immunohistochemical analysis revealed a true splenic cyst with the inner epithelium strongly positive for CA 19-9 and CEA and high levels of cancer antigens in the fluid. The ovarian lesion was a serous cystadenoma. The inner epithelium showed no immunoreactivity for tumour markers which were not measurable in the fluid. True cysts of the spleen are rare; in a few cases, high serum levels of CA 19-9 and CEA have been reported. In such instances, cyst resection or splenectomy is indicated to rule out malignant lesions and to remove the cancer antigen producing epithelium. The reported case shows that the epithelium lining true splenic cysts may produce, besides CA 19-9 and CEA, other tumour markers, in particular cancer antigens 50 and 125. In addition, normal serum values of interleukin 10 correctly predicted the benign nature of the lesion.- - - - - - - - - - ranking = 0.018402088715683keywords = antigen (Clic here for more details about this article) |
6/18. Bilateral oophorectomy in a pregnant woman: hormonal profile from late gestation to post-partum: case report.BACKGROUND: A 16 week pregnant woman presented with massive theca-lutein cysts requiring bilateral oophorectomy. pregnancy progressed uneventfully and spontaneous lactation ensued after delivery. methods: To study the role of the ovary on the hormonal profile at the end of gestation and in post-partum, we measured FSH, estradiol (E2), unconjugated estrone (E1), unconjugated estriol (E3), sex hormone-binding globulin, progesterone, dehydroepiandrosterone sulphate and prolactin at 37 weeks gestation and at 8 h, 4 days, 5 weeks, and 2 months post-partum. RESULTS: These hormones were within the range expected for ovary-intact pregnant and puerperal women until 4 days post-partum. At 5 weeks post-partum, FSH increased to a peri-menopausal range (31.4 IU/l) while estrogens remained within the normal puerperal range (E2=239 pmol/l; E1=102 pmol/l), contrasting with their rapid changes in non-pregnant women after bilateral oophorectomy. At 2 months, while partially breastfeeding, FSH, E2 and E1 were closer to menopausal range (68 IU/l, 136 and 70.2 pmol/l respectively), and hormone replacement was started. CONCLUSIONS: We conclude that the ovary is not required to maintain a normal hormonal profile in late pregnancy and early puerperium. However, the increase in FSH to peri-menopausal levels at 5 weeks post-partum, despite breastfeeding, suggests that the ovary is needed to maintain low FSH concentrations during lactation.- - - - - - - - - - ranking = 0.14285714285714keywords = ca- (Clic here for more details about this article) |
7/18. Case of mature cystic teratoma of the greater omentum misdiagnosed as ovarian cyst.The teratoma of the greater omentum is a very rare entity. We present a case of mature cystic teratoma of the greater omentum misdiagnosed as ovarian cyst. The patient was a 36-year-old woman with an omental teratoma of 5 x 4 x 4 cm and an atrophic left ovary. The histopathologic diagnosis was mature cystic teratoma of the greater omentum and no evidence of immaturity or malignancy was noted. Preoperative tumor marker tests revealed moderate elevation of cancer antigen (CA)125, CA19-9 and carcinoembryonic antigen. The left ovary of the patient was atrophic and possible autoamputation of the ovarian tissue might be suggested.- - - - - - - - - - ranking = 0.0024536118287577keywords = antigen (Clic here for more details about this article) |
8/18. Abnormal steroid excretion in gestational trophoblastic disease complicated by ovarian theca-lutein cysts.serum and urine steroids were examined in two subjects with trophoblastic disease accompanied by large ovarian theca-lutein cysts and compared with those from 10 patients with trophoblastic disease but without palpable cysts. In the patients without cysts normal values were obtained for serum oestradiol, progesterone, 17 alpha-hydroxyprogesterone and androstenedione, and for urinary total oestrogens, pregnanediol, pregnanetriol, and 17-oxosteroids. Nineteen urinary steroid metabolites, quantified by capillary gas-liquid chromatography, were either within reference limits or marginally raised. In several cases relatively minor increases in serum testosterone and cortisol and urinary free cortisol were observed. In contrast, the subjects with cysts showed pronounced excesses of androgen metabolites, 17 alpha-hydroxypregnenolone, pregnanediol, and pregnanetriol, and both exhibited a similar pattern of unusual additional metabolites. The profiles superficially resembled those seen in 21-hydroxylase deficiency adrenogenital syndrome, but there were important discrepancies reflecting known differences in ovarian and adrenal steroid metabolism. Chemotherapy led to decline of human chorionic gonadotrophin concentrations, regression of the cysts, and return to normal of the steroid profile. Excess steroids in the patients with cysts may have originated in the ovary rather than in the trophoblastic tissue.- - - - - - - - - - ranking = 0.71428571428571keywords = ca- (Clic here for more details about this article) |
9/18. Combined tubal and molar pregnancy: case report.A patient with combined pregnancy developed an acute condition in the abdomen 9 weeks after surgical removal of a tubal pregnancy. At laparotomy she was found to have bilateral theca-lutein cysts. After operation, the patient went into preterm labor and was delivered of a male fetus. Pathologic examination of the placenta revealed hydropic change and trophoblastic hyperplasia.- - - - - - - - - - ranking = 0.14285714285714keywords = ca- (Clic here for more details about this article) |
