The histology and management of ovarian cysts found in children and adolescents presenting to a children’s hospital from 1991 to 2007: a call for more paediatric gynaecologists

A Giant Ovarian Cystadenoma in A 20-Year-Old Nulliparous Woman: A Case Report

Giant ovarian cyst itself is defined as a cyst >10 cm in diameter from radiological- examination or the size of the cyst exceeds the umbilicus. Extra-large benign and malignant cysts of the ovary are uncommon and involve diagnostic and management challenges. We present the case of a 20-year-old nulliparous woman who was referred to our center with complaints of abdominal pain and heavy breathing. She benefited from a salphingo-oophorectomy laparotomy procedure. Benign and malignant gynecologic and non-gynecologic etiologies are included in the differential diagnosis of an abdominal mass. Because of the infrequent occurrence or absence of distinctive clinical presentation of the giant ovarian cyst, accurate preoperative diagnosis is challenging.

Laparoendoscopic Ovarian-Sparing Surgery of Adnexal Tumors in Children and Adolescents by General Gynecologists: A 10-Year, Retrospective Cohort Study

Background: In pediatric and adolescent gynecology, ovarian-sparing surgery (OSS) is an approach for preserving the ovaries affected by tumors and torsion during surgical treatment. Materials and Methods: We analyzed participants from a tertiary Gynecology and Obstetrics University Hospital. Participants were patients <19 years of age with adnexal tumors managed surgically with removal of pathologically confirmed ovarian tissue in the period from 2008 to 2017. Results: The average age of 38 patients who underwent surgery for adnexal tumors and were included in the study was 16.78 ± 2.15 years, from 12 to 19 years, with significantly younger patients in the salpingo-oophorectomy/oophorectomy and laparotomy group (P = .036 and P = .001). The laparoscopic approach was performed in 28 (73.68%) patients and laparotomy in 10 (26.31%) patients (P < .0001). Cystectomy was performed in 29 (76.31%), oophorectomy in 1 (2.63%), and salpingo-oophorectomy in 8 (21.05%) patients. A significantly higher number of patients underwent OSS with laparoscopy in scheduled surgical procedure and emergency surgery groups (P = .021 and P = .028). Benign ovarian tumors were found in 31 (81.57%), borderline in 3 (7.89%), and malignant in 4 (10.52%) patients. Conclusion: Our study has shown a high trend in OSS using the endoscopic approach in management of adnexal tumors despite the fact that the management was done by general gynecologists.

Results of Ovarian Sparing Surgery in Pediatric Patients: Is There a Place for Laparoscopy?

Background: Laparoscopy is widely accepted for the surgical treatment of benign ovarian lesions in adult women, with results similar to an open approach when spillage is avoided by different means such as endobag retrieval. This approach is controversial in children. Materials and Methods: Retrospective study (2009-2018) of all pediatric ovarian tumors with histological confirmation treated in a tertiary center. Data regarding preoperative selection criteria, surgical technique, and follow-up were registered. Laparoscopy was used only in tumors without malignant features and whose size allowed retrieving them through a small incision without morcellating. Emphasis was set in ovarian sparing surgery (OSS), comparing the results of open (OP) and laparoscopic (LPC) approach. Results: During the study period, 48 suspicious lesions in 45 patients were operated. Thirty cases (32 tumors) showed benign features (10 cystadenomas, 14 mature teratomas, 6 nontumor lesions); treatment consisted in oophorectomy in 13 (OP 6, LPC 7) and OSS in 17 (OP 5, LPC 12). There was one conversion in the LPC group. Mean follow-up was 3.44 years (range 0.03-8.84), based on annual ultrasound (US) and tumor markers during at least 5 years, recommending a lifetime follow-up by a gynecologist. There was only one relapse in a laparoscopically enucleated cystadenoma, and 2 patients developed contralateral metacronous teratomas. No procedure-related complications happened. Conclusions: Our series, although small and with a limited follow-up, suggest that laparoscopy could be an option of treatment in a subset of highly selected patients, although laparotomy remains the gold standard approach if malignancy is suspected.

Effect of Surgical Specialty on Management of Adnexal Masses in Children and Adolescents: An 8-Year Single-Center Review

STUDY OBJECTIVE

Children with adnexal masses might be managed by pediatric surgeons, urologists or gynecologists, with the potential for different management strategies between specialties. In this study we compared ovarian conservation rates and surgical approach for adnexal masses in children and adolescents managed either by pediatric surgeons/urologists or gynecologists at a tertiary care institution.

DESIGN

Retrospective cohort review.

SETTING

Tertiary pediatric and adult university hospital.

PARTICIPANTS

Patients younger than 18 years of age with an adnexal mass managed surgically with removal of histologically confirmed ovarian or fallopian tube tissue from 2008 to 2015.

INTERVENTIONS

Laparoscopic or open procedure for adnexal mass.

MAIN OUTCOME MEASURES

The primary outcome was rate of ovarian conservation relative to surgical specialty. The secondary outcome was surgical approach relative to surgical specialty.

RESULTS

Forty-eight patients underwent surgery for adnexal masses; 26 (54%) under pediatric surgery/urology and 22 (46%) under gynecology care. Laparoscopy was performed in 5 (19%) pediatric and 19 (86%) gynecology cases (P = .000006). Of 24 patients older than 12 years of age with a benign tumor, 10 (42%) underwent procedures resulting in loss of an ovary with or without fallopian tube; 8 of these (80%) were under pediatric care. Of the remaining 14 (58%) who underwent ovarian conserving surgery, 12 (80%) were under gynecology care (P = .0027).

CONCLUSION

Patients with a benign tumor were significantly more likely to undergo ovary-preserving surgery under gynecology care than under pediatric surgery/urology care. A multidisciplinary team approach involving gynecology and pediatric surgical specialties would be valuable in assessing the merits of ablative or conservative surgery in each case.

Surgically Managed Ovarian Masses at the Royal Children's Hospital, Melbourne -19 Year Experience

BACKGROUND/PURPOSE

To describe the clinicopathological characteristics and management of surgically removed ovarian masses at the Royal Children's Hospital, Melbourne from 1993 to 2012.

METHODS

Medical records were reviewed retrospectively. Data regarding clinical findings, imaging and surgical management were evaluated.

RESULTS

There were 266 ovarian masses found in 258 surgeries (eight had bilateral masses). Most were benign (246/266, 92.5%), 2.3% (6/266) were borderline, and 5.3% (14/266) were malignant. The most common presenting symptom was abdominal pain for benign masses (169/246, 68.7%), and a palpable mass for borderline and malignant masses (12/20, 60.0%). Sensitivity and specificity of ultrasound for detection of malignancy was 64.7% and 52.9% respectively. Ovarian torsion occurred in 22.1% (n=57), none with malignancy, with seven cases diagnosed under one year of age. Sensitivity and specificity of ultrasound for ovarian torsion was 22.0% and 91.9%, respectively. The proportion undergoing ovarian cystectomy rather than oophorectomy has increased from 56.3% during 1993-1997 to 93.8% during 2008-2012 (p<0.005). Ovarian torsion was managed with ovarian conservation in 82.6% of cases between 2008-2012.

CONCLUSION

The majority of pediatric and adolescent ovarian masses were benign. Sensitivity of ultrasound was fair for detection of malignancy, and poor for ovarian torsion. Conservative surgeries are increasingly common.

LEVEL OF EVIDENCE

Level IV - case series with no comparison group TYPE OF STUDY: Retrospective Study.

Surgically treated ovarian lesions in preadolescent girls

INTRODUCTION

The purpose of this study was to investigate the epidemiology and characteristics of surgically treated ovarian lesions in preadolescent girls.

MATERIAL AND METHODS

This was a retrospective cohort study including all 0- to 11-year-old girls operated at a single center from 1999 to 2016 for ovarian cysts, neoplasms or torsions. Patient charts were reviewed for symptoms, preoperative radiological imaging, operative details and histopathology.

RESULTS

We identified 78 girls, resulting in a population-based incidence of 4.2/100 000. Infants (n = 44) presented with benign cysts (42/44, 95%, one bilateral), a benign neoplasm (1/44, 2%) and a torsion without other pathology (1/44, 2%). Torsion was found in 25/29 (86%) ovaries with complex cysts and in 3/15 (21%) ovaries with simple cysts in preoperative imaging (P < 0.001). Most infants were symptomless. Lesions in 1- to 11-year-old girls (n = 34) included benign neoplasms (n = 21/34, 62%), malignant neoplasms (n = 5/34, 15%), a cyst with torsion (n = 1/34, 3%) and torsions without other pathology (n = 7/34, 21%). Torsion was more common in benign (17/21, 81%) than in malignant neoplasms (1/5, 20%) (P < 0.020). Ovarian diameter did not differ between ovaries with or without torsion (P = 0.238) or between benign and malignant neoplasms (P = 0.293). The duration of symptoms in lesions with or without torsion was similar.

CONCLUSIONS

The majority of surgically treated ovarian lesions in preadolescent are benign lesions with torsion. Surgery should be ovary-preserving and performed without delay.

Pediatric ovarian tumors, a challenge for pediatrician and gynecologist: Three case reports (CARE compliant)

RATIONALE

Ovarian or adnexal tumors are very rare in patients below the age of 18 years, most of them being functional cysts, only 10% being malignant. We report 3 cases of ovarian tumors with the aim of revealing the particularities regarding the diagnosis and management of benign and malignant ovarian tumors in pediatric patients.

PATIENT CONCERNS

The 1st case, a 9-year-old girl presented for diffuse abdominal pain, distended abdomen and rapid increase in abdominal volume. The 2nd case describes a 13-year-old female patient admitted for acute abdominal pain and nausea, and the 3rd one was an 18-year-old female teenager who presented for distended abdomen, intermittent diffuse abdominal pain and rapid increase in abdomen volume.

DIAGNOSES

The abdominal ultrasound revealed in all 3 patients suggestive signs for ovarian tumors.

INTERVENTIONS

The 1st patient underwent laparotomy with adnexectomy, and the histopathological exam showed the diagnosis of dysgerminoma. The 2nd patient underwent laparoscopy with adnexectomy, and the histopathological exam revealed a borderline tumor. The 3rd patient benefited by a laparotomy with left ovariectomy, and the histopathological exam pointed out a mature teratoma.

OUTCOMES

The outcome was favorable in all 3 cases, but the patients with dysgerminoma and mature teratoma were further referred to the oncologist for proper assessment.

LESSONS

Laparoscopy may represent the first choice for uncomplicated ovarian masses. The diagnosis and the therapeutic plan must be based on symptoms, pelvic ultrasound, the time of menarche and the potential serum markers.

Selecting treatment method for ovarian masses in children - 24 years of experience

BACKGROUND

Epidemiology and pathology of ovarian tumors in the pediatric population are very different of these encountered in women. Few attempts have been made to analyze the whole spectrum of ovarian pathology in children, and only some of them included series of more than 200 cases. We performed a retrospective analysis of clinical and diagnostic aspects of ovarian tumors and tumor-like lesions in girls in order to identify the characteristics associated with malignancy with an attempt to elaborate a clinical management algorithm.

RESULTS

The study group comprised 214 patients operated on for ovarian tumor in years 1991-2014 at the pediatric surgical center. Non-neoplastic ovarian lesion was diagnosed in 127 females. Sixty-five patients had a benign tumor and 22 had a malignant lesion. Abdominal pain was the most common symptom in the non-malignant lesion group. Patients with ovarian malignancy presented predominantly with abdominal distension and palpable mass. In the non-malignant group imaging studies revealed cystic lesion in 124 patients (68.89%) and solid mass in 10 (5.55%). Malignant lesion showed a solid or mixed structure in all cases. Positive tumor markers were noted in 14 (13.7%) patients with a benign lesion and in 14 (70%) with ovarian malignancy. Large lesions were found in 77.3% of girls with a malignant mass, while only in 32.8% of patients with a benign lesion (p < 0.001). In the group of solid tumors positive tumor marker results occurred more frequently in patients with diagnosed malignant tumors (p < 0.05). Positive tumor markers, large size of the lesion and age below 14 years were independent variables differentiating malignant tumors from non-malignant lesions (p = 0.00000).

CONCLUSIONS

Predominantly solid structures noted on imaging studies, large dimension and positive tumor markers are clinical predictors of malignancy. A diagnosis of purely cystic lesions with negative markers or of a small size should be an indication for a gonad-sparing procedure. Treatment guidelines for ovarian lesions in children should be established on the basis of multicenter prospective studies and introduced as soon as possible in order to improve and unify the ovarian preservation rates across the pediatric surgical centers.

Evaluation and Treatment Results of Ovarian Cysts in Childhood and Adolescence: A Multicenter, Retrospective Study of 100 Patients

STUDY OBJECTIVE

To investigate the characteristics of children with ovarian cysts and evaluate treatment strategies.

DESIGN

Retrospective study.

SETTING

Eight pediatric endocrinology clinics, Turkey.

PARTICIPANTS

A total of 100 children and adolescents with ovarian cysts.

INTERVENTIONS

Patient data collected via retrospective chart review. Patients were stratified according to age into 4 groups (newborns, 1-12 months, 1-8 years, and 8-18 years).

MAIN OUTCOME MEASURES

Special emphasis was given to torsion and tumor cases, concomitant diseases, treatment modalities, and problems during follow-up.

RESULTS

Most newborns and infants were asymptomatic with the cysts being discovered incidentally; in girls ages 1-8, symptoms were common, including breast budding (47.1%, 16 of 34) and vaginal bleeding (29.4%, 10 of 34). Girls older than 8 years mostly presented with abdominal pain (31.6%, 12 of 38) and menstrual irregularity (21.1%, 8 of 38). Most of our patients were diagnosed with a simple ovarian cyst, but 9 patients were found to have ovarian tumors. Ovarian torsion was detected in 7 patients; 5 with large and 2 with small cysts (<20 mm). Two patients had central precocious puberty (CPP) at presentation and 5 patients developed CPP during follow-up. The surgical intervention rate was high (38%, 38 of 100), but was associated with earlier treatment year, and this association remained significant after adjusting for confounders (P = .035).

CONCLUSION

Most girls have simple cysts, which have a favorable prognosis without intervention; however, there might be coexisting pathologies or complications such as tumors, torsion, and CPP; hence these patients should be evaluated accordingly and treated with a multidisciplinary approach.

Ovarian Preservation from Tumors and Torsions in Girls: Prospective Diagnostic Study

STUDY OBJECTIVE

To develop a new decision tree system (DTS) for the management of adnexal masses in prepubertal and adolescent girls, aimed to improve the distinction between benign and malignant masses, help preserve affected ovaries during surgery, and reduce the rate of surgical management of uncomplicated functional ovarian cysts.

DESIGN

A prospective diagnostic study using clinical and ultrasound data collected for all patients younger than 19 years of age with adnexal masses managed between 2006 and 2015.

SETTING

Mother and Child Health Institute of Serbia 'Dr Vukan Čupić' (Belgrade, Serbia).

PARTICIPANTS

Patients (N = 1499) with adnexal masses, of whom 318 were surgically treated.

INTERVENTIONS AND MAIN OUTCOME MEASURES

Ultrasonographic characteristics (Ueland's Morphology Index [MI] and the ovarian crescent sign [OCS]). Patients were managed expectantly or surgically, in line with 3 rules of the DTS. Rule 1: asymptomatic patients having a mass with MI of 4 or less and OCS present, were managed expectantly. Rule 2 (emergency): malignancy was suspected if the MI was 7 or more and no edema of the OCS was present. Rule 3 (nonemergency): malignancy was suspected if the OCS was absent and MI was 5 or more. The diagnostic accuracy was assessed using sensitivity and specificity (P < .05).

RESULTS

No malignancy was found in the group of 1236 patients selected according to the DTS rule 1. Torsion was confirmed in 36% of surgically treated masses (n = 115). The OCS was present in 96% of benign masses in the non-emergency group (n = 149) and in three with microscopic malignancy. In predicting malignancy, the DTS (rules 2 and 3) showed a sensitivity of 93 (95% confidence interval [C.I.]: 82-98); and a specificity of 97 (C.I.: 95-99). Ovarian tissue was preserved from benign (n = 254, 93%) and malignant tumors (n = 3, 7%). Only five (2%) uncomplicated ovarian cysts were surgically treated.

CONCLUSION

The DTS with 3 rules is a very accurate diagnostic tool in the differentiation between benign and malignant ovarian masses. The DTS rule 1 reduces the number of surgical procedures on functional cysts, rules 2 and 3 are very useful in choosing the optimal treatment of adnexal masses, whether or not they are twisted.

Involvement and comfort of gynecologic oncologists in the treatment of pediatric, adolescent, and young adult patients with gynecologic malignancies

OBJECTIVE

To investigate the provision of care for pediatric and adolescent patients by gynecologic oncologists.

METHODS

The present prospective cross-sectional study enrolled attending physicians and fellows specializing in gynecologic oncology from the USA during December 2012 and January 2013. A 33-question survey collecting demographic data and details of participant opinions on existing practices was distributed to potential respondents. Survey responses were aggregated and descriptive analyses were performed.

RESULTS

The survey was distributed to 1252 physicians and 178 (14.2%) surveys were returned; 105 (59.0%) participants thought that the care of patients aged younger than 21 years should be included in their practice. Only 7 (3.9%) participants had received formal training in caring for pediatric patients and young adults; however, 85 (47.8%) felt this should be incorporated into formal fellowship training. Multidisciplinary teams were reported to be the best method for caring pediatric patients by 160 (88.9%) participants but only 42 (23.6%) participants reported that multidisciplinary teams were involved in pediatric gynecologic oncology care at their institutions.

CONCLUSION

Gynecologic oncologists wanted to be involved in pediatric care and open dialogue between specialists could help in the provision of optimal, longitudinal care to these patients. Furthermore, the incorporation of formal pediatric patient-focused training into gynecologic oncology fellowship programs should be considered.

Laparoscopic Outcomes of Adnexal Surgery in Older Children and Adolescents

STUDY OBJECTIVE

To evaluate the outcomes of laparoscopic surgery for the treatment of adnexal pathology in older children and adolescents.

DESIGN

A retrospective cohort review.

SETTING

A tertiary academic center in Istanbul, Turkey.

PARTICIPANTS

Pediatric and adolescent patients aged between 9 and 19 years (n = 69) who underwent laparoscopic surgery for adnexal pathology from January 2005 through September 2015. The patients who were pregnant or with non-gynecologic pathology detected during surgery were excluded from the study.

INTERVENTIONS

Patients were divided into 2 groups according to their age. Group 1 consisted of 31 patients aged between 9 and 16 years and group 2 included 38 patients aged between 17 and 19 years.

MAIN OUTCOME MEASURES

The indication for surgery, procedures performed, anesthesia time, length of hospital stay, pathology findings, and complication rates were evaluated.

RESULTS

Ovarian cystectomy and adnexal detorsion with or without cystectomy were the most frequently performed. Ovary-sparing conservative surgery was possible for all patients, except those with gonadal dysgenesis and testicular feminization (n = 6), who underwent laparoscopic gonadectomy. The most common pathologic finding was mature cystic teratoma (30.2%), followed by benign paratubal cyst, and simple cysts of the ovary. Anesthesia time was shorter in group 2 (P = .018). The procedures performed, length of hospital stay, complication rate, and pathology findings were not significantly different between the 2 groups.

CONCLUSIONS

Laparoscopic surgery can be successfully performed as an efficient, safe, and well tolerated procedure for treating a wide variety of adnexal pathology among children and young adolescents without any significant variation between different age groups.

Preoperative risk stratification of children with ovarian tumors

BACKGROUND

The appropriate operative approach to pediatric patients with ovarian tumors must balance real risk of malignancy with maximal preservation of reproductive potential. We evaluate preoperative risk of malignancy in order to more precisely guide treatment, so as to err on the side of ovarian preservation if at all possible.

METHODS

We retrospectively reviewed the records of all patients undergoing surgical intervention for ovarian tumors at a single institution. The primary endpoint was ovarian malignancy.

RESULTS

Of 502 patients who underwent surgery for ovarian tumors, 44 (8.8%) had malignancies. Malignancy rate (95% confidence interval) was low for cystic lesions <9cm (0.0%, 0.0-2.9%) and for tumor marker-negative heterogeneous lesions <9cm (2.3%, 0.4-12.1%). High-risk profiles for malignancy included tumor marker-positive heterogeneous lesions (66.7%, 35.4-87.9%) and solid tumors ≥9cm (69.2%, 16.2-40.3%). Intermediate risk tumors included cystic tumors ≥9cm (6.8%, 3.5-20.7%), tumor marker-negative heterogeneous lesions ≥9cm (31.2%, 18.0-48.6%), and solid tumors <9cm (11.1%, 4.4-25.3%).

CONCLUSIONS

We developed a decision strategy to help determine who may and may not require an ovarian-sparing approach, which warrants prospective application and validation. Ultimately, the decision to pursue an oncologic surgery with oophorectomy and staging (as opposed to fertility-preserving surgery) should be made after individualized discussion involving the surgeon, patient, and family.

Management of Large Ovarian Neoplasms in Pediatric and Adolescent Females

The overwhelming majority of ovarian cysts in pediatric and adolescent girls are physiologic; however, large simple and complex ovarian lesions often require surgical intervention due to the increased risk of neoplasia. In this review article, we discuss the preoperative evaluation and intraoperative management of large ovarian neoplasms. We review the current literature regarding long term ovarian function and fertility, rates of recurrence and residual disease, and novel surgical approaches. Managing large ovarian neoplasms in the pediatric and adolescent population requires careful preoperative and intraoperative care to optimally resect neoplasia while maximizing fertility and minimizing pain.

Laparoscopic treatment of ovarian cysts in adolescents and young adults

STUDY OBJECTIVE

To investigate the laparoscopic management of ovarian cysts in adolescents and young adults.

DESIGN

A retrospective chart review study.

SETTING

Zekai Tahir Burak Women's Health Research and Education Hospital.

PARTICIPANTS

A total of 282 females aged 25 years or younger underwent laparoscopic surgery for a presumed benign ovarian cyst. Patients were grouped as adolescents (ages 12-19, n = 79) or young adults (ages 20-25, n = 203).

MAIN OUTCOME MEASURES

Surgical approach, operative findings and the correlation of intraoperative diagnosis with the definitive pathological reports.

RESULTS

The mean age of the patients was 21.2 years. At laparoscopic surgery, 89 patients (31.6%) had endometriomas, 47 (16.7%) had dermoid cysts, and 37 (13.1%) had paraovarian cysts. Ninety-seven patients (34.4%) had simple ovarian cysts. Pathological reports revealed that young adults were more likely to have endometriomas (34.0% vs 7.6%, P < 0.01), but dermoid cysts and simple ovarian cysts were more frequent (20.3% vs 15.3%, P < 0.01 and 60.7% vs 40.9%, P < 0.01, respectively).in adolescents. Eleven of the cases (3.9%) were found to have mucinous cystadenomas and fourteen (5.0%) to have serous cystadenomas. Four cysts were malignant (1.4%). Cystectomy was performed in 205 cases (72.7%), fenestration of cyst wall was performed in 53 cases (18.8%), and aspiration was applied in 22 cases (7.8%). The types of operation were not significantly different among adolescents and young adults (P > 0.05). The operative diagnosis was highly correlated with the final pathological reports (kappa value= 0.901, P < 0.001). There were no operative and postoperative complications in our series.

CONCLUSION

With a careful preoperative screening, the laparoscopic surgery of ovarian cyst is an efficient and safe treatment for adolescents and young adults.

Conservative treatment of big yolk sac tumour of the ovary in young girl

We present the case of a large yolk sac tumour of the ovary in a 14-year-old girl with high level of serum alpha-feto-protein (AFP). Multidisciplinary care is important to do appropriate surgical treatment with the aim of fertility preservation.
