1/17. Pancreatic serous cystadenoma associated with islet cell tumour.We report the case of a 29-year-old female patient with a diffuse type of serous cystadenoma involving the entire pancreas except for part of the head, which was replaced by islet cell tumour. Ultrasound and CT showed multiple cysts in the entire pancreas and a solid mass with calcification in the head. MRI characterized the fluid content of the cysts and the extent of disease.- - - - - - - - - - ranking = 1keywords = cystadenoma (Clic here for more details about this article) |
2/17. Prenatal magnetic resonance imaging assisting in differentiating between large degenerating intramural leiomyoma and complex adnexal mass during pregnancy.We present an unusual case in which a 36-year-old patient was referred due to increasing upper left quadrant abdominal pain and a possible left adnexal mass at 22 weeks' gestation. ultrasonography demonstrated a multiseptated cystic mass, with solid components measuring 12 cm in diameter. A thin sonolucency was thought to separate the mass from the uterus and thus the mass was considered consistent with an adnexal mass, possibly a mucinous cystadenoma. A large degenerating leiomyoma could not be ruled out with certainty and magnetic resonance (MR) imaging was performed which depicted a thin band of myometrium encompassing the complex mass and was therefore diagnostic of a degenerating uterine leiomyoma. We discuss the contribution of MR imaging in the noninvasive diagnosis of undetermined solid pelvic masses visualized ultrasonographically.- - - - - - - - - - ranking = 0.2keywords = cystadenoma (Clic here for more details about this article) |
3/17. Laparoscopic extracorporeal oophorectomy and ovarian cystectomy in second trimester pregnant obese patients.OBJECTIVES: To determine whether a modified technique for laparoscopic extracorporal oophorectomy is less complicated and safer than traditional laparoscopic oophorectomy. methods: Four obese patients in their second trimester underwent open laparoscopy for treatment of large ovarian cysts. A Cook Ob/Gyn special cyst aspirator with a 14-gauge aspirating needle was inserted into the abdomen to drain the ovary through a separate 10-mm port; the site of insertion depends on the location of the ovary. After the cyst was decompressed, the 10-mm incision was enlarged to 3 cm, and either extracorporal oophorectomy or cystectomy was performed. RESULTS: No complications occurred. Average blood loss was less than 15 cc; average carbon dioxide insufflation time was less than 20 minutes. Average operating time was 40 minutes, which was significantly less than traditional laparoscopic oophorectomy. The patients were discharged in less than 23 hours. Patient A had a 500-cc dermoid cyst, and subsequently had a normal vaginal delivery at term. Patient B had a 1600-cc cyst removed. She had a cesarian delivery due to cephalopelvic disproportion. Pathological analysis of the specimen identified the mass as a dermoid cyst and serous cystadenoma. Patient C had a 3200-cc ovarian cyst. Currently, she is in her 24th week of gestation. Patient D had a 700-cc simple ovarian cyst removed at her 16th week of gestation. CONCLUSIONS: Laparoscopic extracorporal oophorectomy requires significantly less CO2 insufflation time and a shorter operation time, hence, decreasing the adverse effects on the fetus. The enlarged second trimester uterus made traditional laparoscopy more complicated. Performing the procedure extracorporally decreased the possibility of operative complications.- - - - - - - - - - ranking = 0.2keywords = cystadenoma (Clic here for more details about this article) |
4/17. Unthreatened late pregnancy with a huge mucinous cyst adenoma of the left ovary: report of an unusual case.Benign cystadenomas or cystic teratomas are most frequently diagnosed in pregnancy. In the latter half of pregnancy ovarian tumors are particularly difficult to diagnose. In this report we present a case of a huge mucinous cyst adenoma of the ovary diagnosed in the 26th week of pregnancy. To our knowledge this is the first report of a case of unthreatened late pregnancy with a huge mucinous cyst adenoma of the ovary.- - - - - - - - - - ranking = 0.2keywords = cystadenoma (Clic here for more details about this article) |
5/17. Benign mucinous cystadenoma with stromal luteinization during pregnancy: a hormonally responsive tumor and a rare cause of fetal intrauterine growth restriction.A 32-year-old woman, gravida 4, para 3, had a benign right ovarian mucinous cystadenoma. It was diagnosed 1 month before conception, measured 9 x 7cm, and reached 33 x 24 x 20cm at 38 weeks gestation. Cesarean delivery of a 2250 g normal female infant took place, and the removal of a 6300 g right ovarian cystic mass was also performed. Microscopic and immunohistochemical studies of the cyst wall revealed stromal luteinization and a strong reaction with antiserum to testosterone, estrogen and progesterone.- - - - - - - - - - ranking = 1keywords = cystadenoma (Clic here for more details about this article) |
6/17. Abdominal pregnancy. Case report, review of the literature.Abdominal pregnancy (AP) is a rare form of ectopic pregnancy (EP). It is a medical emergency because of high maternal and fetal morbidity and mortality. early diagnosis is essential. Surgery is indicated as soon as the diagnosis is made. We present a case with AP in the third trimester with malformed fetus and left ovarian tumour. The fetus has been extracted at 33 weeks gestational age; the placenta and the ovarian tumour have been removed five weeks later. pathology showed corpus luteum with hemorrhage, serous cystadenoma, follicular cyst. The fetus died, the woman successfully recovered.- - - - - - - - - - ranking = 0.2keywords = cystadenoma (Clic here for more details about this article) |
7/17. Mucinous cystadenoma of the ovary with functioning stroma and virilization in pregnancy: a case report and review of the literature.Virilization caused by ovarian tumors with functioning stroma during pregnancy is extremely rare and has been reported in many ovarian tumors. In mucinous cystadenomas with maternal virilization during pregnancy the stromal cells responsible for the hormone secretion resemble lutein or leydig cells and have been referred to as luteinized stromal cells. We present a case of a 30-year-old, gravida 2, para 1, woman who presented at approximately the 38th week of pregnancy with features of virilization. At the same time, a cesarean section was performed because of fetal distress and a male weighing 3,030 g without any gross abnormalities was delivered. A large tumor of the right ovary was detected and a right salpingo-oophorectomy was performed. Histopathologically, the tumor proved to be a benign mucinous cystadenoma. Masses typically resembling lutein stromal cells or leydig cells of the testes or ovarian hilus were found in the wall of the cyst below the mucinous epithelium. No crystalloids of Reinke were identified. The stromal component of the tumor was characterized as functioning stroma with luteinized stromal cells. The glandular mucinous epithelium showed focal positivity for human chorionic gonadotrophin. The cytoplasm of the luteinized stromal cells reacted strongly and diffusely with antiserum for vimentin. Also, the cytoplasm of the luteinized stromal cells showed focal intense positivity for synaptophysin, and focal mild positivity for human chorionic gonadotrophin. Staining results for oestrogen and progesterone receptors were negative. In conclusion, we present an unusual case of clinical virilization during pregnancy associated with an ovarian mucinous cystadenoma with functioning stroma. The virilizing manifestations disappeared after removal of the ovarian neoplasm, supporting the perception that the functioning ovarian stroma was responsible for the androgen production.- - - - - - - - - - ranking = 1.4keywords = cystadenoma (Clic here for more details about this article) |
8/17. Huge mucinous cystadenoma of the pancreas developing during pregnancy: a case report.A 33-year-old woman, gravida 2, para 1, was found to have a huge intra-abdominal cyst (2619 ml) in the 15th week. The cyst increased in volume to 3660 ml during the next 31 days. A tentative diagnosis of ovarian or pancreatic mucinous cystadenoma was made. Since the cyst was considered to cause fetal intra-uterine growth restriction, the patient underwent surgery in the 23rd week of pregnancy. The cyst was found to originate from the pancreas, and distal pancreatectomy with splenectomy was performed. The specimen weighed 5500 gm, which is the largest so far reported. Her postoperative course was uneventful, and she had a healthy full-term infant. Histological diagnosis was a benign mucinous cystadenoma. Up to the present, there have been three reported cases of pancreatic mucinous cystadenoma, including our case, and two cases of pancreatic mucinous cystadenocarcinoma, in association with pregnancy. Our case is the third reported of successful resection of the tumor during pregnancy resulting in a healthy infant.- - - - - - - - - - ranking = 1.4keywords = cystadenoma (Clic here for more details about this article) |
9/17. Management of ovarian cysts in pregnancy: a case report.According to recent epidemiological studies on ovarian cysts during pregnancy one out of 600 are, in most cases, benign neoformations. The most frequent histological type reported is mature cystic teratoma (50% of the cases), followed by functional cysts (13%), benign cystadenomas (20%) and ovarian cancer (0.6%). Most adnexal masses are asymptomatic and spontaneously resolve before the 16th week of amenorrhoea. On the other hand, some cases are persistent forms which can cause complications for the mother and fetus. The objective of this work was to review the existing literature from an epidemiological point of view, with an emphasis on diagnostic and therapeutic management. We have paid particular attention in our review to the use of diagnostic techniques and non surgical therapies such as laparoscopy, which in expert hands and adopting particular skills, can be considered as on approach to ovarian cysts in pregnancy. We present the case of a patient with an ovarian cyst during pregnancy that was a successfully treated with laparoscopy.- - - - - - - - - - ranking = 0.2keywords = cystadenoma (Clic here for more details about this article) |
10/17. Mucinous cystadenoma of the ovary with stromal luteinization and hilar cell hyperplasia during pregnancy.A 32-year-old woman was delivered of a healthy, full-term infant by cesarean section, at which time a large ovarian cyst was removed. The cyst proved to be a mucinous cystadenoma with prominent luteinization of the stroma subtending the epithelium and with numerous foci of hyperplastic leydig cells in the cyst wall and ovarian hilum. These hormonally induced changes must be recognized in order to avoid mistaking them for invasive epithelial components.- - - - - - - - - - ranking = 1keywords = cystadenoma (Clic here for more details about this article) |
