Bilateral ovarian teratoma complicated with carcinosarcoma in a 68 year old woman: a case report

Surgical Management of Adnexal Masses in the Pediatric and Adolescent Age Group: Our Experience

CONTEXT

Adnexal masses in girls represent a wide pathological spectrum. We performed a retrospective analysis of clinical and diagnostic aspects of adnexal masses in girls.

AIMS

To analyze the clinical characteristics and surgical management of adnexal masses in children and adolescents.

SETTINGS AND DESIGN

Retrospective observational analysis from 2000 to 2020.

SUBJECTS AND METHODS

This analysis was performed on 28 children under the age of 17 years with adnexal masses who were managed by us at tertiary care centers of Delhi-NCR. Patients were analyzed based on their age at the time of admission, their presenting complaints, clinical and radiological findings, tumor markers, management, and follow-up.

RESULTS

The age ranged between newborn and 17 years. Abdominal pain, nausea with vomiting, and abdominal lump was the most common presenting complaints. Pelvic ultrasound with or without color Doppler done in all patients and computed tomography, magnetic resonance imaging was performed in seven patients preoperatively. Adnexal masses were unilateral in 26 (92.85%) patients and bilateral in 2 (7.15%) patients. Five babies had antenatal diagnosis of ovarian cysts. Serum alpha fetoprotein (AFP) and beta-human chorionic gonadotropin (b-HCG) were normal in all 19 tested patients. Cancer antigen 125 (CA-125) was raised in three ovarian tumors out of 9 tested patients. Laparoscopy was performed in 23 out of 28 patients (30 ovaries). Ovarian cyst torsion was present in 50% patients. Ovarian cystectomy was done in 10 (33.3%) patients. Six (20%) ovaries were saved by detorsion of the ovary and deroofing of the cyst with or without ovarian biopsy. Oophorectomy was done in five (16.7%) patients. Salpingo-oopherectomy had to be done in seven (23.3%) patients. Histopathology revealed functional nonneoplastic lesions in 18 cases (66.7%), benign neoplastic lesions in 8 cases (29.6%), and malignant neoplastic lesion in 1 case (3.7%).

CONCLUSIONS

Adnexal masses in children are generally benign. AFP, b-HCG, and CA-125 in ovarian torsion are within normal limits. Urgent surgery is required if torsion is established. The ovary should be preserved wherever possible.

Ovarian Carcinosarcoma and Its Association with Mature Cystic Teratoma and Primary Tubal Carcinoma

Introduction. Carcinosarcoma is an uncommon form of ovarian cancers, classified as being part of the group of mixed epithelial and mesenchymal tumors. The occurrence of carcinosarcoma in association with a mature cystic teratoma and synchronous tubal carcinoma is very rare. Case Report. A 69-year-old woman presented with a pelvic mass. An abdominal computerized tomographic scan detected a 15 cm right pelvic mass which was suggestive of malignant transformation of a dermoid cyst. Intraoperative, bilateral ovarian masses (left 10 cm and right 12 cm) with diffuse peritoneal metastatic nodules were identified. Histologically, the left ovarian mass was composed of 2 components including carcinosarcoma and mature cystic teratoma, whereas the right ovarian mass represented a mature cystic teratoma with serosal surface involvement of high-grade serous adenocarcinoma. The left fallopian tube was macroscopically unremarkable but contained a 5.0 mm focus of high-grade serous adenocarcinoma in the distal part, with adjacent serous tubal intraepithelial carcinoma. Conclusion. As the fallopian tube has recently been proposed to be an origin for a majority of pelvic or ovarian high-grade serous adenocarcinomas, tubal carcinoma may be the origin for ovarian carcinosarcomas through an epithelial-mesenchymal transition. The coexistence of ovarian carcinosarcoma and teratoma in the present case should represent a collision tumor.

Our experience with adnexal masses in the pediatric age group and review of literature

Background and objectives

Adnexal masses are rare in the pediatric age group. We present our experience with 20 patients with adnexal masses.

Design and setting

This retrospective observational analysis was performed on 20 children with adnexal masses who were treated at our institute between May 2011 and November 2015.

Patients and methods

Fifteen pediatric patients who were admitted between May 2011 and November 2015 were reviewed and retrospectively analyzed based on their age at the time of admission, their presenting complaints, clinical and radiological findings, tumor markers, management and follow-up.

Results

The patients' age at the time of admission ranged between 3 days and 12 years. Abdominal pain and lump were the most common presenting complaints.Four patients (20%) had antenatally diagnosed cystic ovarian lesions. On postnatal scan, two patients had a simple cyst measuring less than 6 cm, which resolved on follow-up ultrasound at 3 months. One neonate had a simple cyst, larger than 6 cm on postnatal scan, which was managed by marsupialization. One antenatally diagnosed patient had a dermoid cyst that required oophorectomy.Ten patients (50%) had dermoid cyst and underwent complete surgical excision of the mass. Based on histopathologic results, two of these patients had immature teratoma and required adjuvant chemotherapy (Bleomycin, Etoposide, and Cisplatin). The serum AFP levels of these patients were carefully monitored.One patient with bilateral ovarian cysts was diagnosed with Van Wyk-Grumbach syndrome, which resolved significantly after a 3-month regimen of thyroxin supplementation.Five patients presented with torsion and required emergency surgery-three had mature teratoma, one had an immature teratoma and one had large simple cysts.

Conclusion

The majority of ovarian tumors are benign. Accurate staging, complete resection and chemotherapy for the treatment of malignant tumors have contributed to excellent survival rates in these patients.

Ovarian teratoma displaying a wide variety of tissue components in a broiler chicken (Gallus Domesticus): morphological heterogeneity of pluripotential germ cell during tumorigenesis

Spontaneous ovarian teratoma was found in a seven-week-old female Chunky broiler chicken that was slaughtered for food. On post-mortem inspection, a spherical tumor mass attaching to a juvenile ovary was found in the abdominal cavity. Histopathologically, the tumor was comprised of immature mesenchymal stroma and a variety of mature tissue elements of mesodermal and ectodermal origin. In addition, there were multiple indistinguishable tissue elements, which showed no malignant cytological features but were unidentifiable as to corresponding embryological layer of origin. These heterogeneous teratoma tissues consisted of a variety of glandular, cystic, duct-like, and tubular structures, some of which exhibited a lining by a mixture of both keratinizing/non-keratinizing stratified squamous epithelial cells and cuboidal/columnar epithelial cells. The ovarian tetatoma was considered a benign and congenital one. The highly diverse differentiation of the teratoma might have manifested a morphological aspect of intrinsic character of the pluripotential germ cells during tumorigenesis.

Radical surgical cytoreduction in the treatment of ovarian carcinosarcoma

OBJECTIVE

Carcinosarcomas are rare and aggressive ovarian malignancies. Treatment recommendations, which include surgical cytoreduction followed by platinum based chemotherapy, have been based on small amounts of retrospective data or extrapolated from experience with high-grade epithelial ovarian adenocarcinoma. Our objective was to determine the effects of radical primary cytoreduction on progression-free survival (PFS) and overall survival (OS).

METHODS

Following IRB approval, records of women with ovarian carcinosarcomas diagnosed between 2000 and 2012 at our institution were reviewed. Demographics, tumor characteristics, treatments, PFS, and OS were collected. Patients were divided into three groups based on the amount of residual disease: >1cm of disease, ≤ 1 cm of disease, or no visible disease. Chi-square and student's t-test were used to compare variables among groups. Kaplan-Meier survival curves were generated and compared with the log-rank test.

RESULTS

51 patients with ovarian carcinosarcoma were identified and all underwent primary cytoreductive surgery. Following surgical cytoreduction, 18 patients (35%) had no visible disease, 20 (39%) had ≤ 1 cm of disease, and 13 (25%) had >1cm of residual disease. Median PFS varied significantly among groups: 29 vs. 21 vs. 2 months (p=0.036) as did median OS: 57 vs. 32 vs. 11 months (p=0.015). When patients with stage 3 disease were analyzed separately, median OS still varied significantly among groups: 57 versus 31 versus 3 months (p=0.009).

CONCLUSION

Degree of surgical cytoreduction appears to correlate with PFS and OS. Radical surgery resulting in no visible disease is recommended for the upfront surgical treatment of ovarian carcinosarcoma.
