Recurrent Bilateral Serous Cystadenomas in a Premenarchal Girl: A Case Report and Literature Review

BackgroundOvarian serous cystadenomas are rare in children. No case of recurrence after surgical resection in a premenarchal girl has been published.CaseAn 8-year-old presented with abdominal pain and ultrasound showed bilateral ovarian cystic masses with normal clinical and laboratory exam. Cystectomies were performed revealing serous cystadenomas. Ten months later, her pain returned and ultrasound showed new cysts. Persistence of cysts and symptoms required repeat surgery with the same pathology.Summary and conclusionPremenarchal girls with ovarian cystic masses require surgical intervention in cases of persistent symptoms, uncertain diagnosis, or concern for ovarian torsion. With reassuring imaging and tumor markers, conservation of the ovary can be achieved with cystectomy alone. Ultrasound follow-up is recommended after surgical resection until bimanual exam can be performed.     

Rare case of a paratubal cystadenoma with bilateral hydrosalpinges in an infertile woman

ObjectiveSerous tumors can occur on the surface of the ovaries and—rarely—as primary tumors on the peritoneal surface. However, the origin of extraovarian serous tumors is unknown. An unusual case of a serous tumor is presented here.Case reportA 34-year-old nulligravid woman presented for evaluation of her primary infertility, with acute abdominal pain. At laparoscopy, a paratubal cyst, independent of the ovaries, was found to be associated with bilateral hydrosalpinges. The final pathology diagnosis was of a benign paratubal serous cystadenoma.ConclusionWe present an unusual case of a paratubal serous cystadenoma with bilateral hydrosalpinges in an infertile woman, which was resected laparoscopically..     

Mujer joven con masa quística intraabdominal gigante

Introduction

Giant intra-abdominal cystic masses are a rare entity in our environment. The most common locations are the ovary, mesentery, and omentum.

Case report

A 29-year-old woman gave a history of abdominal distension and pain in the lower abdomen-pelvis for several months. Radiological studies showed a giant cystic tumor measuring 35 × 31 × 14 cm, displacing visceral structures and occupying almost the entire abdominal cavity, with no apparent ovarian origin. After laparotomy and right oophorosalpingectomy, the existence of a 14-kg serous cystadenoma was confirmed.

Conclusions

The presence of an intraabdominal cystic lesion requires a differential diagnosis among various origins (ovary, mesentery, urinary bladder, etc.). Even today, with advances in radiology, the definitive diagnosis is reached during surgery. In serous cystadenomas, the treatment of choice is excision of the cyst and affected annex.     

Primary spontaneous inguinal endometriosis: Two cases with emphasis on the diagnostic approach

ObjectiveWhile endometriosis is common, inguinal endometriosis with hernia is rarely observed, making its preoperative diagnosis challenging.Case reportWe report two cases of inguinal endometriosis with different presentations and focus on tailored surgical treatment. The two patients in our series presented with painful swelling in the right groin area. Surgery and pathological examination confirmed the diagnosis of endometriosis in both cases. Herniorrhaphy and excision of the extraperitoneal round ligament were performed in one patient with concomitant inguinal endometriosis and indirect inguinal hernia.ConclusionWe highlight the importance of the preoperative evaluation of concomitant pelvic endometriosis, round ligament involvement, and endometriosis within the inguinal hernia sac. Inguinal endometriosis with or without hernia should be considered even in reproductive-aged women without a previous medical and surgical history. Postoperative hormonal therapy, including dienogest, can be considered to prevent disease recurrence.     

A Huge Ovarian Mucinous Cystadenoma in a 15-Year-Old Girl with Situs Inversus Totalis: Report of a Rare Case

BackgroundOvarian mucinous cystadenomas with situs inversus totalis are infrequent in pubertal girls. Surgical techniques on their treatment without affecting ovary anatomical and physiological function have always been a great challenge.CaseA 15-year-old girl presented with abdominal distension and pain due to some huge growths. Computed tomography imaging showed that the heart and whole abdomen viscera were inversely located. Two big low-density masses were found in the abdominopelvic cavity. An exploratory laparotomy was performed and 2 tumors were removed. Pathology confirmed a mucinous cystadenoma.Summary and ConclusionOvarian mucinous cystadenomas with situs inversus totalis can be detected with detailed physical and radiological examination. For adolescent female patients, particular attention should be paid to protect the reproductive anatomical structure during surgery.     

Torsión anexial bilateral en la posmenopausia

Adnexal torsion is a relatively common complication of adnexal masses that occur mainly in reproductive age. Diagnosis is difficult and the definitive diagnosis is usually established after surgery. We report a case of bilateral ovarian torsion in a post-menopausal woman who complained of sudden abdominal pain. After laparotomy, two serous cystadenomas were discovered, the largest measuring 26 cm. Both adnexa were twisted. Subtotal hysterectomy and bilateral oophorectomy was performed, producing symptom resolution.     

Spontaneous abdominal wall endometriosis: A Case Report and review of the literature

ObjectiveWe present a case of spontaneous abdominal wall endometriosis presenting as a painless nodular mass in a woman with no prior history of abdominal surgery.Case reportAbdominal wall endometriosis (AWE) is an uncommon form of endometriosis, usually arising due to a past history of cesarean section or abdominal hysterectomy. However, in rare cases, abdominal wall endometriosis can arise in women with no prior history of abdominal surgery. A 48-year-old woman presented to our obstetrics and gynecology clinic with a painless nodular mass in the right lower quadrant of the abdomen. Abdominal wall ultrasound showed a hypoechoic heterogenous mass under the skin. Wide surgical resection of the mass was conducted and post-operative histopathological report revealed abdominal wall endometriosis.ConclusionSpontaneous abdominal wall endometriosis is an uncommon pathologic condition in which accurate diagnosis is difficult. As an increasing number of obstetrical and gynecological procedures are conducted worldwide, surgeons should keep this clinical entity in the differential diagnosis of any abdominal mass in reproductive-aged females regardless of their past surgical history.     

Benign ovarian serous tumors: a re-evaluation and proposed reclassification of serous "cystadenomas" and "cystadenofibromas"

OBJECTIVE: Serous cystadenomas and cystadenofibromas of the ovaries are currently regarded as neoplasms and are considered the most common ovarian neoplasms. The purpose of this study is to determine what proportion of benign serous tumors contain an epithelial proliferation (the hallmark of a neoplastic process in nearly all other sites) that can be considered neoplastic as opposed to reactive in nature. METHODS: An unselected series of 113 ovarian serous tumors (76 serous cystadenomas and 37 serous cystadenofibromas) were histologically evaluated. A 1-mm in diameter area of epithelial proliferation was considered potentially neoplastic. RESULTS: Eight tumors (7%) displayed at least 1 mm of epithelial proliferation (1% of serous cystadenomas and 19% of serous cystadenofibromas). CONCLUSION: The vast majority of benign serous tumors may not be bona fide epithelial neoplasms, but rather, may represent cystically dilated glandular inclusions (cystadenomas) and fibromas with epithelial inclusions (cystadenofibromas). A recently published study evaluating clonality in serous cystadenomas found that the vast majority are polyclonal and thus supports this hypothesis. These findings have important implications for the pathogenesis of ovarian cancer, for the distribution of ovarian neoplasms, and for the interpretation of molecular biological studies of ovarian tumors.     

Recurrence Rates for Pediatric Benign Ovarian Neoplasms

Study ObjectiveTo examine the recurrence rates of pediatric benign ovarian neoplasmsMethodsA retrospective review of females up to 21 years of age who underwent surgery for a benign ovarian neoplasm at 8 pediatric hospitals from January 2010 through December 2016 was conducted. Data include primary operation details, follow-up imaging, and reoperation details.ResultsFour hundred and twenty-six females were included in our cohort, with a median age of 15 years at the time of the primary operation. Of the patients, 69% had a mature teratoma, 18% had a serous cystadenoma, and 8% had a mucinous cystadenoma. Two-thirds of patients underwent ovarian-sparing surgery. There were 11 pathologically confirmed recurrences (2.6%) at a median follow-up of 12.8 months. The pathologically confirmed recurrence was 10.5 per 100 person-months at 12 months (SE = 5.7) for mucinous cystadenomas and 0.4 months (SE = 0.4) for mature teratomas (P = .001). For half of the patients, the pathologically confirmed recurrences occurred by 12.8 months, and for 75%, they occurred by 23.3 months. There were no differences in reoperation or recurrence on the basis of initial procedure (ovary-sparing surgery vs oophorectomy).ConclusionWe measured the pathologically confirmed recurrence rate for pediatric benign ovarian neoplasms in a large cohort. Oophorectomy was not protective against recurrence. Mucinous cystadenomas were at a greater risk of pathologically confirmed recurrence.     

A Way to Reduce the Occurrence of Intraoperative Capsule Rupture in Presumed Clinically Early-stage Ovarian Cancer with Adhesions to the Abdominal Wall

Study ObjectiveTo present a procedure to reduce the occurrence of intraoperative capsule rupture in presumed clinically early-stage ovarian cancer with adhesions to the abdominal wall.DesignStepwise presentation of the procedure with narrated video footage.SettingThe occurrence of intraoperative capsule rupture exerts a negative effect on the prognosis of early-stage ovarian cancer [1,2]. Thus, it is important to reduce intraoperative capsule rupture to improve the oncologic outcome of such patients. In this video we describe a laparoscopic procedure to minimize the risk of intraoperative capsule rupture in presumed clinically early-stage ovarian cancer with adhesions to the abdominal wall. A 52-year-old woman was referred from a local clinic for a 6 × 6 × 4-cm left ovarian mass and a 7 × 6 × 6-cm right ovarian mass. Her serum cancer antigen 125 level was 214.4U/mL. Pelvic magnetic resonance imaging and positron emission tomographic/computed tomographic imaging showed no evidence of metastatic diseases or lymph node involvement. A diagnosis of ovarian malignancy was suspected.InterventionsLaparoscopic evaluation suggested that the right adnexa was adhered to the right abdominal wall and there was no evidence of tumor seeding in the peritoneal cavity. We collected the peritoneal lavage fluid. Since pelvic adhesiolysis between the right adnexa and the abdominal wall may increase the occurrence of intraoperative capsule rupture of the ovarian tumor, leading to a worse clinical outcome, we decided to remove both the right adnexa as well as the adhered peritoneum. The key steps of the procedure are summarized as follows. First, the utero-ovarian ligament and tubal isthmus were coagulated and excised. Second, the pelvic peritoneum was excised, and the infundibulo-pelvic ligament and ureter were identified and mobilized. Third, the infundibulo-pelvic ligament was coagulated and excised. Fourth, the pelvic peritoneum which was adhered to the right adnexa was dissected off the ureter and excised. Then, the resected right adnexa as well as the adhered peritoneum were collected in a disposable pocket and removed to avoid further contamination. Adenocarcinoma was diagnosed by frozen section evaluation. So, surgical staging was performed laparoscopically, and consisted of hysterectomy, bilateral salpingo-oophorectomy, pelvic and para-aortic lymph node dissection, omentectomy, and random peritoneal biopsies from the pelvis, paracolic gutters, and undersurfaces of the diaphragm. Final pathologic reports showed ovarian clear cell carcinoma with involvement of both ovaries and the adhered peritoneum.ConclusionOur method is effective for intact removal of the involved adnexa without rupture and the adhered pelvic peritoneum with potential for tumor seeding.     

Solitary primary peritoneal carcinoma arising from the omentum

ObjectiveTo report a case of isolated omental peritoneal carcinoma without peritoneal carcinomatosis.Case reportA 60-year-old female with abdominal distention was found to have a pelvic mass. Under the impression of ovarian cancer, laparotomy was performed only to show one isolated mass over omentum. Serial examination and pathology study including immunochemical staining indicated primary peritoneal serous carcinoma.ConclusionIsolated omental peritoneal carcinoma without peritoneal carcinomatosis and ascites is rare, and whether this represented a unique entity with different chemotherapy response and treatment outcome from the disseminated form of primary peritoneal carcinoma needs to be reviewed in the future.     

Well-Differentiated Papillary Mesothelioma With Two Synchronous Serous Gynaecologic Carcinomas in a 62-Year-Old Woman: Lessons Learned for the Gynaecologic Surgeon

BackgroundWell-differentiated papillary mesothelioma (WDPM) is a rare tumor of unknown malignant potential. It is typically diagnosed incidentally during benign gynaecologic surgery. We report the first published case of WDPM in a woman with synchronous serous carcinomas of the gynaecologic tract and highlight lessons learned for general gynaecologists and gynaecologic oncologists alike.CaseA 62-year-old woman was referred for assessment and management of a pelvic mass. Intraoperatively, metastatic high-grade carcinoma was identified and the patient underwent a successful debulking procedure that identified 3 synchronous tumors: ovarian high-grade serous carcinoma, endometrial serous carcinoma, and 2 foci of pelvic WDPM.ConclusionThis case of WDPM with 2 synchronous serous gynaecologic tumors is a novel addition to the reported literature and offers many learning points about the disease. Gynaecologic surgeons should be familiar with WDPM, as it is predominantly found in reproductive-aged women undergoing benign gynaecologic surgery, may be linked with endometriosis, and has an unclear malignant potential. Multidisciplinary care is essential for accurate diagnosis. Further research is needed to clarify the optimal management and surveillance of WDPM.     

Key Clinical Predictors in the Early Diagnosis of Adnexal Torsion in Children

ObjectiveAdnexal torsion (AT) accounts for 2.7% of cases of acute abdominal pain in children. When AT is undiagnosed, ovarian blood supply is compromised, eventually leading to tissue necrosis. Because the clinical presentation of AT is nonspecific, preoperative diagnosis is challenging. The purpose of this study was to identify predictors that differentiate AT from other sources of acute abdominal pain.MethodsThis study was an IRB-approved retrospective chart review of girls age 4-18 y/o with acute abdominal pain who then underwent surgical evaluation. Data collected included age, menarchal status, symptoms, physical exam findings, laboratory tests, imaging studies, operative procedures and postoperative diagnosis. Factors associated with AT were included in a logistic regression model. A receiver operator characteristic (ROC) curve based on this model was then constructed in order to determine its ability to predict AT.Results94 patients presented with acute abdominal pain; 45 were diagnosed with AT and 49 with other causes of abdominal pain. Presence of intermittent pain (P < .0217), non-radiating pain (P < .0229) and increased adnexal size (P < .0032) were significantly associated with AT in the final model. The area under the ROC curve was equal to 0.8601, suggesting excellent discrimination between AT and other causes of acute abdominal pain by using these 3 parameters.ConclusionKey clinical and imaging findings can aid in the early diagnosis of AT in children. Future prospective studies will focus on development of a clinical predictive model for the diagnosis of AT in the pediatric population.     

Transvaginal Natural Orifice Transluminal Endoscopic Hysterectomy and Apical Suspension of the Vaginal Cuff to the Uterosacral Ligament

Study ObjectiveTransvaginal natural orifice transluminal endoscopic surgery (vNOTES) offers similar advantages of traditional vaginal surgery including no incisional pain as well as a better cosmetic outcome. Furthermore, vNOTES allows the surgeon to overcome the limited surgical space and lack of exposure when using the traditional vaginal instrumentation. Vaginal uterosacral ligament suspension subsequent to vaginal hysterectomy has the advantages of a mesh-free, minimally invasive approach for the treatment of pelvic organ prolapse. The objective of this video is to demonstrate a surgical technique and a few tips and tricks for vNOTES hysterectomy and uterosacral ligament suspension.DesignStepwise demonstration of the vNOTES technique for hysterectomy and vaginal apical suspension to the uterosacral ligament with narrated video footage.SettingAn academic tertiary referral center. The ethics committee ruled that approval was not required for this study.PatientsA 53-year-old woman.InterventionsvNOTES hysterectomy and apical suspension to the uterosacral ligament.Measurements and Main ResultsA 53-year-old woman (gravida 5, para 4) presented with Pelvic Organ Prolapse Quantification System stage III symptomatic uterine prolapse. The patient was selected to be operated on via a vaginal port. The video presents some tips and tricks to aid the surgeon to perform this surgery in a safe and timely manner using the vaginal GelPOINT system (Applied Medical, Rancho Santa Margarita, CA).ConclusionvNOTES for repair of POP by uterosacral ligament suspension via a vaginal port is a feasible technique with promising cosmetic results. This technique allows the surgeon to expose the ureter well and lower the risk of ureteric injury. Additionally, this approach avoids mesh complications and should also decrease the risk of abdominal wound infection because of the absence of incisions on the abdomen.     

Low-grade serous primary peritoneal carcinoma

Objective10% of women with serous ovarian cancer have low-grade carcinomas. These patients are diagnosed at a younger age, have a longer overall survival and a lower response rate to platinum-based chemotherapy compared to women with high-grade serous ovarian carcinoma. It remains unclear if these features are similar in women with low-grade primary peritoneal cancer (PPC). To further explore this issue, a retrospective analysis of the clinical and pathologic characteristics of women with low-grade serous PPC was performed.MethodsA retrospective study of 53 patients with low-grade serous PPC evaluated at a single institution from 1986 to 2009 was performed. All cases were reviewed by a gynecologic pathologist to confirm low-grade serous PPC.ResultsMedian age at diagnosis was 51.7 years (range 27.1–82.4). 46 patients (86.8%) underwent primary surgery, with optimal tumor reduction achieved in 30 patients (65.2%). 48 patients (90.6%) received chemotherapy as part of their initial treatment. At the completion of primary treatment, 66.7% of patients were noted to have persistent or progressive disease. With a median follow-up of 66.1 months, the 5-year PFS was 16%, yet the 5-year OS was 69%.ConclusionTo our knowledge, this is the first report of women with low-grade serous PPC. Similar to low-grade serous ovarian carcinoma, patients with low-grade serous PPC have high rates of persistent disease at the completion of primary treatment yet a long overall survival. Further study focusing specifically on low-grade serous ovarian and primary peritoneal carcinomas is needed to determine the optimal treatment of these diseases.     

Laparoscopic Resection of a High Grade Serous Ovarian Cancer that Recurred at the Vaginal Stump with Extensive Pelvic Adhesions after Complete Surgical Staging

Study ObjectiveTo show laparoscopic resection of a high grade serous ovarian cancer that recurred at the vaginal stump with extensive pelvic adhesions after complete surgical staging.DesignStepwise demonstration of the procedure with narrated video footage.SettingUniversity hospital.InterventionsWe reported a case of a 62-year-old woman with a history of complete surgical staging of high grade serous ovarian cancer staged IIB, which consisted of hysterectomy, bilateral salpingo-oophorectomy, pelvic and para-aortic lymph node dissection, and omentectomy, about 18 months before this admission. She received 6 courses of carboplatin/paclitaxel combination therapy after complete surgical staging and achieved complete remission. About 12 months after the last course of chemotherapy, she visited the local clinic because of irregular vaginal bleeding. Physical examination revealed a 3 × 3 × 2 cm³ mass at the vaginal vault. Biopsy of the mass was performed under colposcopy, and pathological reports showed recurrent high grade serous cancer. Her serum cancer antigen 125 level was in normal range. Positron emission tomographic/computed tomographic imaging (PET/CT) showed no evidence of disease dissemination. A diagnosis of recurrent high grade serous ovarian cancer was made. After the biopsy of the recurrent mass, there were no visible lesions, which made us believe that laparoscopy management would not contribute to intraperitoneal spread of the tumors. Therefore, laparoscopic resection of the vaginal stump was scheduled. The key steps of the procedure were summarized as follows. First, the bowels were released from the side abdominal wall to expose bilateral external iliac vessels. Second, bilateral ureters were identified and mobilized to avoid incidental ureter injuries. Third, we opened the rectovaginal space and detached the rectum from the posterior vaginal wall. Fourth, the posterior vesical wall was separated from the vaginal stump. After exposure of the key anatomic landmarks, laparoscopic resection of the vaginal stump was performed safely. Final pathologic report showed recurrent high grade serous ovarian cancer. The patient received 6 courses of carboplatin/paclitaxel combination therapy, and maintenance therapy with olaparib was suggested, but the patient refused to accept this suggestion. She is still in complete remission 8 months after surgery.ConclusionLaparoscopic resection of a high grade serous ovarian cancer that recurred at the vaginal stump with extensive pelvic adhesions after complete surgical staging was achieved successfully in a logical way. The critical point of the procedure is to expose the key anatomic landmarks of the pelvis to avoid incidental injuries [1].     

Effect of tubal sterilization technique on risk of serous epithelial ovarian and primary peritoneal carcinoma

ObjectiveTo determine the effect of excisional tubal sterilization on subsequent development of serous epithelial ovarian cancer (EOC) or primary peritoneal cancer (PPC).MethodsWe performed a population-based, nested case–control study using the Rochester Epidemiology Project. We identified all patients with a diagnosis of serous EOC or PPC from 1966 through 2009. Each case was age-matched to 2 controls without either diagnosis. Odds ratios (ORs) and corresponding 95% CIs were estimated from conditional logistic regression models. Models were adjusted for prior hysterectomy, prior salpingo-oophorectomy, oral contraceptive use, endometriosis, infertility, gravidity, and parity.ResultsIn total, we identified 194 cases of serous EOC and PPC during the study period and matched them with 388 controls (mean [SD] age, 61.4 [15.2] years). Fourteen cases (7.2%) and 46 controls (11.9%) had undergone tubal sterilization. Adjusted risk of serous EOC or PPC was slightly lower after any tubal sterilization (OR, 0.59 [95% CI, 0.29–1.17]; P = .13). The rate of excisional tubal sterilization was lower in cases than controls (2.6% vs 6.4%). Adjusted risk of serous EOC and PPC was decreased by 64% after excisional tubal sterilization (OR, 0.36 [95% CI, 0.13–1.02]; P = .054) compared with those without sterilization or with nonexcisional tubal sterilization.ConclusionsWe present a population-based investigation of the effects of excisional tubal sterilization on the risk of serous EOC and PPC. Excisional methods may confer greater risk reduction than other sterilization methods.     

p63 expression in epithelial ovarian tumors

Ovarian cancer is a highly lethal disease and its underlying biology is poorly understood. The p63 is a homologue gene of the tumor suppressor p53. p63 appears to be important for the development and differentiation of reproductive epithelium and interacts with p53 in human tumorigenesis. This study presents the immunoexpression of the p63 in benign and malignant epithelial ovarian tumors. We evaluated the p63 immunoexpression in 91 ovarian benign cystadenomas (29 mucinous and 62 serous) and in 29 ovarian malignant tumors (3 mucinous borderline, 3 serous borderline, 17 serous carcinomas, 2 endometrioid, 2 undifferentiated, 1 mucinous, and 1 clear-cell carcinoma) using a monoclonal antibody clone 4A4 (1:200), which recognizes all p63 variants. The tumors were considered p63 positive if 5% or more cells presented nuclear immunostaining. We observed 85.7% of positivity in benign tumors, 50% in borderline tumors, and 8.7% in invasive ovarian cancer (P < .0001). The benign serous cystadenomas were positive in 91.9% of cases and benign mucinous cystadenomas in 72.4% (P= .02). These data suggests an important role of p63 in the control of ovarian epithelium behavior. The p63 may be involved in the development of benign and malignant epithelial ovarian tumors.
