Abstract
Ovarian steroid cell tumors are rare, representing less than 0.1% of all ovarian neoplasms. Among the myriad causes of hirsutism, ovarian tumors account for 1% of the reported cases. We present the case of a 49-year-old parous postmenopausal woman who sought medical attention for hirsutism for 2 years. This case illustrates the unusual and interesting connection between rare ovarian pathology and the clinical manifestation of hirsutism in a postmenopausal patient. Her ultrasonography and MRI showed a right adnexal mass of solid-cystic consistency with thin septations. Her laboratory workup revealed high levels of total testosterone of 256 ng/ml (8.4-48.1ng/ml) and free testosterone of 7.36 pg/ml (0.2-4.1 pg/ml), while DHEAS - 234 µg/dl (35.4-256 µg/dl) and CA125 - 15.8U/L (0.0-35 U/L) were in the normal range. She underwent exploratory laparotomy with a total abdominal hysterectomy and oophorectomy. Histopathological examination and immunohistochemistry conclusively established the presence of a steroid cell tumor, specifically classified as "Not Otherwise Specified"(NOS), in the right ovary.

Abstract
Adult granulosa cell tumor, the most common malignant ovarian sex cord-stromal tumor, harbors the characteristic mutation c.402C>G (p.C134W) in the FOXL2 gene in ~90% to 95% of cases. To date, no other variants of FOXL2 mutations have been identified in these tumors. Here we report the first case of an adult granulosa cell tumor with a novel FOXL2 point mutation c.398C>T (p.A133V) presenting in a 64-year-old postmenopausal woman. The patient underwent total hysterectomy and bilateral salpingo-oophorectomy for atypical endometrial hyperplasia and gross examination revealed an incidental 3.2 cm right ovarian mass with a solid, bright yellow, homogeneous cut surface. Microscopically, ~30% of the tumor showed a nested growth pattern composed of uniform tumor cells with oval nuclei and a moderate amount of pale cytoplasm, while the remaining areas consisted of a bland storiform fibromatous stroma. Reticulin stain demonstrated loss of the individual pericellular network within the nested areas, while the pericellular staining pattern was retained in the background stromal component. FOXL2 sequencing analysis was performed in both components and revealed a c.398C>T (p.A133V) mutation in the nested component, whereas wild-type FOXL2 sequence was identified in the fibromatous stroma. Sections from the uterus showed a low-grade endometrioid endometrial adenocarcinoma with superficial myometrial invasion. The patient underwent adjuvant vaginal cuff brachytherapy for the endometrial carcinoma and is alive and well at 8 months follow-up. This case illustrates that new FOXL2 mutations may be detected in ovarian sex cord-stromal tumors with increasing use of routine molecular testing, adding to the complexity of the pathologic diagnosis. In the right morphologic and clinical context, a FOXL2 mutation-even if it is different from the dominant hotspot mutation c.402C>G (p.C134W)-can support the diagnosis of adult granulosa cell tumor.

Abstract
Struma ovarii is a well-known ovarian teratoma made up of benign thyroid tissue. These lesions demonstrate variable, normal architecture and normal thyroid immunohistochemical staining with positivity for TTF1, PAX8, and thyroglobulin. Though most are benign, some of these lesions can also present with a malignant component. Within this article, we review the most common diagnostic malignancies including papillary thyroid carcinoma, strumal carcinoid, highly differentiated follicular thyroid carcinoma, and other thyroid carcinomas. We additionally review the use of TTF1 staining to assist in differentiating these lesions from surrounding gynecologic epithelium, which is imperative in making such diagnoses. In highlighting these entities, we hope to provide practicing pathologists with an effective and concise review of these lesions to assist in more challenging cases of struma ovarii.

Abstract
Background Solid pseudopapillary neoplasms (SPNs) are uncommon tumors of low malignancy with a generally favorable prognosis, mostly originating from the pancreas. To date, 12 cases of SPNs with a primary ovarian origin (SPN-Os) have been reported globally, and their detailed characteristics have not been fully elucidated. Case description We reported the 13th SPN-O case, which occurred in a 52-year-old woman with an 18.5 cm left ovarian mass. Four imaging methods, including ultrasound, computed tomography, magnetic resonance imaging and positron emission tomography, were utilized before surgery. An elevated level of serum cancer antigen 125 was detected and a total hysterectomy plus bilateral salpingo-oophorectomy was performed. Microscopic examination revealed a typical solid pseudopapillary structure. The tumor cells were stained focally for pan-cytokeratin, synaptophysin, CD99 and CD10, while β-catenin, vimentin and CD56 were diffusely expressed. The Ki-67 proliferation index was 3%, and immunohistochemical (IHC) staining for chromogranin-A, inhibin-a, and E-cadherin was negative. No evidence of recurrence or metastasis was observed by clinical and imaging data during a 5-month postoperative follow-up. Conclusion This is a report of an unusual case of a primary ovarian SPN with an up-to-date review of SPN-Os. A minimum combination of imaging methods and IHC stains was proposed for SPN-Os, which may prove beneficial in clinical practice.

Abstract
Metastasis from non-mammary malignant neoplasms to the breast is rare and represents 0.2%-1.3% of all breast malignancies. Fine needle aspiration cytology (FNAC) is the first line of investigation for any breast lump and cyto-morphological appearance of primary breast malignancies is well documented. Occasionally metastasis to the breast may be the initial presentation and can masquerade clinically as primary breast malignancy. The present case describes the clinical and cytological challenges in an unusual case of ovarian carcinoma with initial presentation as breast mass, mimicking as inflammatory carcinoma. In cytology the breast lesion was initially misdiagnosed as primary breast carcinoma and subsequently diagnosed as metastatic ovarian carcinoma based on core needle biopsy findings, aberrant immuno-profile and clinical findings; thus making the complex case worthy of discussion.

Abstract
Cancer of unknown primary (CUP) is a well-studied entity with guidelines available for the management of patients with CUP. The peritoneum represents one of the metastatic sites in CUP, and peritoneal metastases (PM) could present as CUP. PM of unknown origin remains a poorly studied clinical entity. There is only one series of 15 cases, one population-based study, and few other case reports on this subject. Studies on CUP, in general, cover some common tumour histological types like adenocarcinomas and squamous carcinomas. Some of these tumours may have a good prognosis though majority have high-grade disease with a poor long-term outcome. Some of the histological tumour types commonly seen in the clinical scenario of PM like mucinous carcinoma have not been studied. In this review, we divide PM into five histological types-adenocarcinomas, serous carcinomas, mucinous carcinomas, sarcomas and other rare varieties. We provide algorithms to identify the primary tumour site using immunohistochemistry when imaging, and endoscopy fails to establish the primary tumour site. The role of molecular diagnostic tests for PM or unknown origin is also discussed. Current literature on site-specific systemic therapy based on gene expression profiling does not show a clear benefit of this approach over empirical systemic therapies.

Abstract
The move toward consistent and comprehensive surgical pathology reports for cancer resection specimens has been a key development in supporting evidence-based patient management and consistent cancer staging. The International Collaboration on Cancer Reporting (ICCR) previously developed a data set for reporting of the ovarian, fallopian tube and primary peritoneal carcinomas which was published in 2015. In this paper, we provide an update on this data set, as a second edition, that reflects changes in the 2020 World Health Organization (WHO) Classification of Female Genital Tumours as well as some other minor modifications. The data set has been developed by a panel of internationally recognized expert pathologists and a clinician and consists of "core" and "noncore" elements to be included in surgical pathology reports, with detailed commentary to guide users, including references. This data set replaces the widely used first edition, and will facilitate consistent and accurate case reporting, data collection for quality assurance and research, and allow for comparison of epidemiological and pathologic parameters between different populations.

The cytokeratin 17 expression in primary ovarian tumors has diagnostic but not prognostic significance. Virchows Arch 2022; 481:201-212.

Abstract
We assessed the value of cytokeratin 17 (CK17) expression for the differential diagnosis between primary ovarian mucinous tumors and metastases from the gastrointestinal tract (GIT) and the significance of CK17 expression in a broad spectrum of primary ovarian tumors with respect to their prognosis. The sample set consisted of 554 primary ovarian tumors and 255 GIT tumors. In the primary ovarian tumors, a higher CK17 expression (in > 10% of tumors cells) was present only in 0-11.4% of all tumors (including mucinous tumors, micropapillary serous borderline tumors, clear cell, endometrioid, and high-grade serous carcinomas). The only exception was low-grade serous carcinoma, where higher CK17 expression was present in 24% of cases. Concerning GIT tumors, the higher levels of CK 17 expression (in > 10% of tumor cells) were observed in the upper GIT tumors (68.5% of pancreatic ductal adenocarcinoma, 61.6% of gallbladder adenocarcinoma, and 46% of gastric adenocarcinoma), which differs substantially not only from most of the primary ovarian tumors, but also from colorectal carcinoma (3.7%; p < 0.001). The results of our study suggest that expression of CK17 can potentially be used as an adjunct marker in differential diagnosis between primary ovarian mucinous tumors and metastases from the upper GIT, but not from colorectal carcinoma. However, in GIT tumors, CK17 can be used in the differential diagnosis between adenocarcinomas of the upper and lower GIT. Statistical analysis did not reveal strong association of CK17 expression with clinicopathological variables or patient outcomes in any primary ovarian tumors.

Abstract
Combined analysis of cytokeratin 7 (CK7) and cytokeratin 20 (CK20) is often used for assessing the origin of metastatic cancer. To evaluate the diagnostic utility of CK7 and CK20, tissue microarrays containing 15,424 samples from 120 different tumor types and subtypes and 608 samples of 76 different normal tissue types were analyzed by immunohistochemistry. CK7 positivity was seen in 52% (8.7% weak, 5.9% moderate, 37% strong) and CK20 positivity in 23% (5.1% weak, 3.4% moderate, 15% strong) of interpretable tumors. Of 8390 positive tumors, 1181 (14%) showed positivity for CK7 and CK20, 5380 (64%) showed positivity for CK7 alone, and 1829 (22%) showed positivity for CK20 alone. CK20 predominated in gastrointestinal tract, urothelial and Merkel cell carcinomas. CK7 was usually negative in prostate cancer and colorectal cancer. Combined evaluation of CK7/CK20 revealed the best diagnostic utility in CK20 positive tumors, where CK7 negativity is often linked to colorectal origin while CK7 positivity argues for urothelial origin or mucinous ovarian cancer. Associations with unfavorable tumor features were found for cytokeratin 7 loss in breast cancer of no special type, urothelial and renal cell carcinomas, for CK7 overexpression in high-grade serous ovarian and gastric cancer, and for CK20 overexpression in urothelial carcinoma. CK20 loss was linked to MSI in gastric (p = 0.0291) and colorectal adenocarcinoma (p < 0.0001). These analyses provide comprehensive data on the frequency of CK7 and CK20 immunostaining - alone or in combination - in human cancers. These data facilitate interpretation of CK7/CK20 immunostaining in cancers.

Multi-Disciplinary Care Planning of Ovarian Cancer in Older Patients: General Statement-A Position Paper from SOFOG-GINECO-FRANCOGYN-SFPO. Cancers (Basel) 2022; 14:cancers14051295. [PMID: 35267603 PMCID: PMC8909025 DOI: 10.3390/cancers14051295] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/28/2021] [Revised: 02/25/2022] [Accepted: 02/25/2022] [Indexed: 02/01/2023] Open
Abstract
Simple Summary This position paper aims to provide practitioners a proposal for multidisciplinary care planning for older patients with ovarian cancer from the time of suspected diagnosis. The first-line treatment of advanced ovarian cancer involves several interdependent sequences: cytoreductive surgery, (neo)adjuvant chemotherapy and maintenance targeted treatments. In older patients, care planning must be adapted to their geriatric parameters and consider the geriatric impact of each treatment sequence to allow treatment completion. Care planning should be centered on patient motivation and imply multidisciplinarity. Each step of treatment plan should be reconsidered in light of a geriatric assessment and follow-up. Studies are needed to prospectively evaluate the impact of geriatric vulnerability parameters at each step of the treatment agenda and the impact of geriatric interventions on patient outcomes. Abstract In this position paper the Société Francophone d’OncoGériatrie (SOFOG; French-speaking oncogeriatric society), the Société Française de Pharmacie Oncologique (SFPO, French society for oncology pharmacy), the Groupe d’Investigateurs Nationaux pour l’Étude des Cancers de l’Ovaire et du sein (GINECO, National Investigators’ Group for Studies in Ovarian and Breast Cancer) and the Groupe Français de chirurgie Oncologique et Gynécologique (FRANCOGYN) propose a multi-disciplinary care planning of ovarian cancer in older patients. The treatment pathway is based on four successive decisional nodes (diagnosis, resectability assessment, operability assessment, adjuvant, and maintenance treatment decision) implying multidisciplinarity and adaptation of the treatment plan according to the patient’s geriatric covariates and her motivation towards treatment. Specific attention must be paid to geriatric intervention, supportive care and pharmaceutical conciliation. Studies are needed to prospectively evaluate the impact of geriatric vulnerability parameters at each step of the treatment agenda and the impact of geriatric interventions on patient outcomes.

Cho CH, Cho M, Park JK. Biomarker barcodes: multiplexed microfluidic immunohistochemistry enables high-throughput analysis of tissue microarray. LAB ON A CHIP 2021; 21:3471-3482.

Abstract
We present a multiplexed microfluidic immunohistochemistry (IHC) technology that enables high-throughput analysis of tissue microarrays (TMAs) using the patterns of biomarker barcodes, which consist of a series of expressed linear patterns of specific biomarkers. A multichannel poly(dimethylsiloxane) microfluidic device was reversibly assembled by the pressure of simple equipment for multiplexed IHC on each core of TMA or cell microarray (CMA) section slides. By injecting primary antibodies from different biomarkers independently into each channel, multiplexed immunostaining can be performed on each core of TMA. We confirmed the equal immunostaining quality regardless of the channel orders and core positions in the slide. Four different biomarkers (ER, PR, HER2, and Ki67) were used for the demonstration of distinctive expression patterns on CMAs which consist of six different breast cancer cell lines, and it was confirmed that these bar-like signals could be a biomarker barcode for the TMA core. A biomarker barcode of breast cancer patient-derived TMA was quickly scanned by a slide scanner and compared to the conventional method for breast cancer diagnosis. This "barcode-IHC" concept, which has been verified by performing multiplexed microfluidic IHC on CMA and TMA samples, provides high reproducibility and the potential of high-throughput screening with molecular diagnostic capability.

Immunohistochemically detectable thyroglobulin expression in extrathyroidal cancer is 100% specific for thyroidal tumor origin. Ann Diagn Pathol 2021; 54:151793.

Abstract
Thyroglobulin is a secreted 660 kDa glycoprotein produced by thyroid follicular cells used in diagnostic pathology to secure or exclude a thyroidal origin of metastases of unknown primary tumors. This study was performed to estimate specificity of thyroglobulin immunohistochemistry. 9974 tumor samples from 109 different tumor types and subtypes as well as 608 samples of 76 different normal tissue types were analyzed by immunohistochemistry in a tissue microarray format. Thyroglobulin was strongly expressed in all normal thyroid samples but not in any other normal tissues. Thyroglobulin immunostaining was detected in 99.1% of 106 thyroid adenomas, 98.1% of 364 papillary, 95.2% of 147 follicular, and 7.5% of 40 anaplastic thyroid cancers. Twelve of 15 thyroid samples that were thyroglobulin negative on TMAs showed at least a weak focal thyroglobulin positivity in corresponding large sections, suggesting higher sensitivity of large section analysis. Thyroglobulin positivity in one diffuse large B-cell lymphoma of the thyroid, one chondrosarcoma metastasis to the thyroid, and 42.4% of 92 medullary thyroid cancers was considered to be caused by diffusion of thyroidal colloid from destroyed or even intact adjacent follicles. Thyroglobulin positivity was, however, not seen in 6403 extrathyroidal tumors from 104 different tumor types and subtypes. Our data demonstrate a complete specificity of positive thyroglobulin immunostaining for thyroid origin in tumor tissues obtained from extrathyroidal locations. However, for all tumors located within the thyroid, false positivity can occur as a result of tissue contamination by thyroglobulin rich thyroid colloid from adjacent normal tissue.

Ultrasound-guided fine needle aspiration of ovarian masses: Assessment of diagnostic accuracy and risk stratification using a categorical reporting system. Cytopathology 2021; 32:441-458. [PMID: 34015167 DOI: 10.1111/cyt.12987] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/11/2020] [Revised: 04/05/2021] [Accepted: 04/09/2021] [Indexed: 01/20/2023]
Abstract
INTRODUCTION The present study was undertaken to assess the accuracy of fine needle aspiration cytology (FNAC) and cell-block immunocytochemistry, and to estimate the risk of malignancy, using a categorical reporting system, in the diagnosis of ovarian masses. METHODS This was a 5-year retrospective study of FNAs of ovarian masses. The cytological diagnoses were categorised as inadequate, non-neoplastic, benign neoplasms, indeterminate for malignancy, suspicious for malignancy and malignant neoplasms. The cytology was correlated with the corresponding histopathology to assess the diagnostic accuracy and risk of malignancy associated with each diagnostic category. RESULTS Of a total of 66 703 FNAs performed during the study period, 580 (0.9%) were performed on ovarian masses. Of these, 40 (6.9%) were reported as non-neoplastic; 76 (13.1%) as benign neoplasms; 14 (2.4%) as indeterminate for malignancy, 48 (8.3%) as suspicious for malignancy, 337 (58.1%) as malignant neoplasms and 65 (11.2%) as inadequate for interpretation. Immunocytochemistry (ICC) was performed on 99 (17%) aspirates. Subsequent histopathology was available in 208 (35.8%) cases. On cyto-histopathological correlation, 183 (88%) were concordant and 25 (12%) were discordant. The overall sensitivity, specificity, positive and negative predictive values and diagnostic accuracy for diagnosing ovarian malignancy were 88.4%, 85.7%, 96.8%, 60.0% and 88% respectively. Risk of malignancy for each category was 80%, 0%, 4.5%, 66.7%, 88.5% and 98.5% respectively. CONCLUSIONS Ultrasound-guided FNAC has high specificity and diagnostic accuracy for preoperative diagnosis of ovarian malignancies and hence is a valid diagnostic procedure in certain clinical situations. Reporting using a categorical system imparts uniformity and also provides the clinicians with an associated risk of malignancy to guide further management.

Abstract
The term "ovarian carcinoma" encompasses at least five different malignant neoplasms: high-grade serous carcinoma, low-grade serous carcinoma, endometrioid carcinoma, mucinous carcinoma, and clear cell carcinoma. These five histotypes demonstrated distinctive histological, molecular, and clinical features. The rise of novel target therapies and of a tailored oncological approach has demanded an integrated multidisciplinary approach in the setting of ovarian carcinoma. The need to implement a molecular-based classification in the worldwide diagnostic and therapeutic setting of ovarian cancer demanded a search for easy-to-use and cost-effective molecular-surrogate biomarkers, relying particularly on immunohistochemical analysis. The present review focuses on the role of immunohistochemistry as a surrogate of molecular analysis in the everyday diagnostic approach to ovarian carcinomas.

Abstract
Background
Primary mucinous epithelial ovarian adenocarcinoma (mEOC) constitutes a small percentage (2–5%) of ovarian cancer. Our aim is to understand the clinicopathological characteristics and survival results of patients with mEOC after a long-term follow-up.
Materials and Methods
This is a retrospective study of primary mEOC cases treated at a tertiary cancer center in India, from January 1, 2005, to December 31, 2012.
Results
Out of 958 malignant ovarian tumors, 52 (5.43%) were mucinous adenocarcinoma. Nearly 71.2% of cases were of early-stage disease, and the remaining were of advanced-stage disease. After a follow-up period of 63 months (range: 1–138 months), the 5-year actuarial overall survival for stages I, II, III, and IV was 92.5, 70, 38.5, and 0%, respectively. Among advanced-stage tumors, half of them progressed without undergoing cytoreductive surgery and died.
Conclusion
Most of the mEOC cases present in early stages and have good clinical outcome. Patients with advanced-stage disease do not respond well to standard chemotherapy regimens in use and have poor survival figures. The use of primary cytoreduction should be considered in the place of interval cytoreduction for advanced mEOC.

Abstract
Over the years, immunohistochemistry has emerged as a powerful tool for a more precise diagnosis of certain tumors in gynecologic oncopathology and resolving certain diagnostic dilemmas with significant treatment implications. Certain specific immunohistochemical (IHC) markers have been useful in the more correct identification of rare tumors, characterized by specific molecular signatures. Immunohistochemistry has also been useful in the identification of underlying genetic events, characterizing various tumors, as well as precancerous lesions. This review will focus upon the judicious application of various IHC antibody markers in gynec oncopathology, including authors' experience during "sign-outs" and especially during interaction with other oncology colleagues within the institutional disease management group. The updated references were retrieved from PubMed.

Abstract
Mucinous carcinomas with signet ring cells in the ovary, particularly those composed predominantly of signet ring cells, are extremely rare, and in vast majority of cases, they represent metastasis from another site such as the stomach, appendix, pancreaticobiliary tract, bladder, and breast (Hristov et al., 2007, Kiyokawa et al., 2006, Vang et al., 2006, Young, 2006). Malignant Brenner tumor is also rare comprising less than 0.5% of ovarian carcinoma. Although mixed Brenner-Mucinous tumors are relatively common, the combination of a primary ovarian signet ring carcinoma with a malignant Brenner tumor is unique and to the best of our knowledge not previously reported in the literature.

Abstract
Peritoneal surface oncology has emerged as a subspecialty of surgical oncology, with the growing popularity of surgical treatment of peritoneal metastases comprising of cytoreductive surgery (CRS) and hyperthermic intraperitoneal chemotherapy (HIPEC). Pathological evaluation plays a key role in multidisciplinary management but there are still many areas where there are no guidelines or consensus on reporting. Some tumors presenting to a peritoneal surface oncology unit are rare and pathologists my not be familiar with diagnosing and classifying those. In this manuscript, we have reviewed the evidence regarding various aspects of histopathological evaluation of peritoneal tumors. It includes establishing a diagnosis, appropriate classification and staging of common and rare tumors and evaluation of pathological response to chemotherapy. In many instances, the information captured is of prognostic value alone with no direct therapeutic implications. But proper capturing of such information is vital for generating evidence that will guide future treatment trends and research. There are no guidelines/data set for reporting cytoreductive surgery specimens. Based on the authors' experience, a format for handling/grossing and synoptic reporting of these specimens is provided.

Abstract
In recent times, there has been a growing tendency to treat advanced gynaecological malignancies with neoadjuvant chemotherapy (NACT), with the goal of reducing tumour volume and enhancing operability resulting in optimal cytoreduction. This approach is used in particular for patients with advanced high-grade serous carcinoma of the ovary, fallopian tube or peritoneum. Pathology plays a crucial role in the management of these patients, both before and after NACT. Prior to initiation of NACT, a biopsy should be performed, usually of the omental cake, to confirm that a malignancy is present, to identify the site of origin of the tumour and to type and grade the tumour. Histopathologists must be aware of the resultant morphological effects of NACT when examining specimens following interval cytoreduction surgery. Tumour typing and grading, and even the identification of residual neoplasia, are particular challenges. Immunohistochemistry, when used judiciously, can be a useful adjunct in certain scenarios. A pathological assessment of the response to chemotherapy, and the pathological stage should be provided in the pathology report, as these may inform prognosis and subsequent management. We present a comprehensive overview of the relevant clinical and pathological aspects pertaining to NACT for gynaecological malignancies for the practicing surgical pathologist.

Abstract
Background: Ovarian cancer is the leading cause of gynecologic cancer-related death. Histological
assessment remains the standard clue for the diagnosis of ovarian carcinoma. Misinterpretation and inconsistent
application of histological criteria may lead to significant interobserver variability and poor reproducibility of
the diagnosis. In this study, we investigated the discrepancy in histological diagnosis and the significance of a designed
panel of immunohistochemical markers for the improvement of the diagnostic reproducibility of ovarian carcinomas.
Methods: We performed a retrospective study on 74 ovarian carcinomas. All tumor slides were independently
reviewed by two pathologists. The results for seven available immunomarkers as p53, WT-1, p16INK4A, CK7,
CK20, and estrogen and progesterone receptors were determined for all cases by immunohistochemistry. Results:
The histological diagnosis review performed using standard histology showed a concordance of diagnoses in 86% of
cases with Cohen’s kappa of 0.80. Immunohistochemical results increased significantly the diagnosis reproducibility
with a concordance of 91% and a Cohen’s kappa of 0.86 (P = 0.001). Conclusion: Although the histological diagnosis
remains reliable, the use of a designed panel of immunohistochemical markers improves significantly the interobserver
concordance and the classification accuracy of ovarian carcinomas.

Abstract
This study was conducted to develop a novel algorithm for determining the origin of tumors by combining analysis of cluster patterns with immunocytochemistry (ICC) for markers in cells from fine-needle aspirates of ascites. We used LBC, based on SurePathTM (BD Diagnostics) technology, to screen 96 peritoneal fluid samples from patients with known malignancies and from 10 control patients with cirrhosis. Following dual ICC staining for cytokeratin 7 (CK7) and paired box gene 8 (PAX8), we developed an algorithm using immunoreactivity and three-dimensional (3D) cluster patterns to correlate staining and 3D cluster patterns with common primary origins that included stomach, ovarian, pancreatobiliary tract, colon, lung, and breast cancers. With the application of an automatic digitalized image analyzer, competence performance was analyzed using receiver operating characteristics (ROC) curve analysis. CK7 and PAX8 staining and 3D cluster patterns were used to differentiate primary origins. Samples from patients with stomach cancer were no 3D cluster /CK7+/PAX8- with area under the curve (AUC) of 0.8699 in ROC curve analysis. Samples from ovarian cancer patients were large 3D cluster/CK7+/PAX8+ with AUC of 0.9812. Samples from pancreatobiliary tract cancer patients were small 3D cluster/CK7+/PAX8- with AUC of 0.8772. The remaining cancer samples, including breast, lung and colon cancer samples, had similar patterns of large 3D clusters/CK7+/PAX8- with AUC of 0.882, especially for lung cancer. SurePathTM technology, using 3D cluster patterns and dual ICC for CK7 and PAX8 in peritoneal fluid samples, can provide important information for determining specific primary origins in cases of unknown primary carcinoma.

Abstract
Signet ring cell carcinoma (SRCC) of the ovary is most commonly metastatic from a primary lesion. Primary ovarian SRCC is rare, and the distinction between primary and metastatic SRCC of the ovary may be difficult. We herein present a case of primary SRCC of the ovary in a 54-year-old woman presenting with a right ovarian mass sized 20.5×16.5×11.5 cm. Total abdominal hysterectomy with bilateral salpingo-oophorectomy, partial omentectomy and incidental appendectomy were performed. Upon histological examination, mucinous carcinoma composed predominantly of signet ring cells was observed in the right ovary. The results of immunohistochemical examination included diffuse positivity for cytokeratin (CK)7 and CK20, but the tumor was negative for estrogen receptor, progesterone receptor, caudal type homeobox 2 and Wilms' tumor gene 1. A preoperative computed tomography (CT) scan of the abdomen and a postoperative positron emission tomography-CT scan did not reveal any suspicious extraovarian lesions. Based on the histological and clinicoradiological examinations, this case was diagnosed as a primary ovarian SRCC.

Abstract
Granulosa cell tumors (GCTs) comprise 2% to 5% of ovarian neoplasms, with unpredictable patterns of recurrence. The HER family, GATA4, and SMAD3 genes are reportedly involved in GCT proliferation and apoptosis and may serve as new predictors of recurrence. The aim of the study was to evaluate novel predictors of recurrence in GCT from a large single institution cohort. Patients diagnosed with GCTs (n=125) between 1975 and 2014 were identified. Clinicopathologic parameters were obtained and immunohistochemical evaluation was performed of calretinin, inhibin, HER2, CD56, SMAD3, and GATA4. Statistical analyses were conducted using Fisher exact test and Kaplan-Meier survival curves and Cox regression analysis. The median follow-up period was 120 months (range, 1-465 mo). Recurrence was noted in 12/125 (9.6%) patients. Kaplan-Meier analysis showed a shorter mean disease-free interval in whites versus blacks (P=0.001), stage III-IV versus stage I-II (P=0.0001), patients treated with surgery+chemotherapy versus surgery (P=0.0001), mitotic rate ≥4 (P=0.005), severe nuclear pleomorphism (P=0.013), high HER2 expression (P=0.001), high CD56 expression (P=0.001), and high SMAD3 expression (P=0.001). On Cox regression analysis, SMAD3 and type of treatment received were the only 2 independent prognostic factors for disease-free interval (P=0.03 and P=0.007, respectively). On subanalysis for early-stage (stage I) GCTs, the need for adjuvant chemotherapy and high expression of SMAD3 continued to be independent predictors of recurrence (HR=10.2, P=0.01 and HR=8.9, P=0.001, respectively).

Abstract
Non-epithelial ovarian cancers (NEOC) constitute a group of uncommon malignancies and their treatment is still a challenging task. Collectively, these tumours account for about 10% of all ovarian cancers and occur in all age groups from childhood to old-age. They include malignancies of germ cell origin, sex cord-stromal cell origin, and a variety of extremely rare ovarian cancers, such as small-cell carcinomas and sarcomas. Each of these classifications encompasses multiple histologic subtypes. It is imperative that these rare tumours are managed with accurate diagnosis, staging, and treatment, to optimise the outcome. The aetiology and molecular origins of each sub-group of NEOC remain largely unresolved, and international cooperation to promote high quality translational research is crucial. Much effort has been made into researching the molecular mechanisms underlying epithelial ovarian cancers, but far less is known about the genetic changes in NEOC. In this article, it is provided an overview of the current knowledge on the incidence, clinical presentation, pathology, genetics, therapeutic interventions, survival and prognostic factors of adult and juvenile granulosa cell tumours (GrCT), Sertoli-Leydig Cell tumours (SLCT) and small cell carcinoma of the ovary. We also consider future potential therapeutic targets in these rare cancers.

Abstract
Sertoli-Leydig Cell Tumour (SLCT) is included under sex-cord stromal tumour of testis or ovary. Ovarian pathology is an extremely rare entity constituting less than 0.5% of all ovarian neoplasms. Majority of the cases present at younger age group, i.e., 2nd and 3rd decade of life. The clinical presentation depends on either mass effect or excess hormone production. Virillization symptoms are the most common presentation and depend upon the quantity of androgen production. Most of the patients have a unilateral mass without extraovarian spread and present at stage-I. Treatment and prognosis depends on the degree of the differentiation and the stage of the disease. Here, we report a case of SLCT of the ovary in a young female. The patient initially presented with pain abdomen due to mass effect and was treated with conservative surgery followed by adjuvant chemotherapy due to the presence of poorly differentiated pathology with heterologous elements.

Abstract
Primary clear cell colorectal carcinoma (CCC) is a very rare entity accounting for only 35 cases reported in the Literature. CCC is neither classified as a distinct entity nor is it defined as a CRC variant because its ontogeny remains unclear. Most of the reported CCC were found in the distal colon in patients with a mean age of 56 years. Histologically, clear cell change is the main morphologic feature and may present in a "pure" form, composed exclusively of clear cells, or in a "composite" form, admixed with other morphologically different components. It is possible to distinguish two biologically different types of CCC, with different clinical-pathologic features, therapeutic management and diagnostic criteria: a) Intestinal CCC consisting of an aggressive neoplasm, affecting mainly adult men, characterized by an intestinal-type immunoprofile (CK20+, CK7-, CEA+, CDX-2+) and b) Müllerian CCC consisting of an indolent carcinoma of the sigmoid-rectum, affecting young women, characterized by a different (CK7+, CK20-, CEA-, CA125 +) immunoprofile. Considerable diagnostic difficulties can arise in distinguishing CCC and primary or secondary clear cell neoplasms, such as metastases from renal carcinoma, lower urinary tract, female genital tract, adrenal gland, mesothelioma, melanoma and primary intestinal PEComa. In this paper we review the Literature with two additional cases in order to define the diagnostic criteria of CCC.

Abstract
Ovarian Large Cell Neuroendocrine Carcinoma (LCNEC) is a recently described rare entity, which even more rarely occurs in a 'pure' form without any associated surface epithelial-stromal or germ cell component. Cervix metastasis of ovarian LCNEC has not been reported previously. We report here a case of ovarian LCNEC in a 35-year-old female who presented with abdominal pain and amenorrhea. Grossly the left ovary showed a solid cystic tumour measuring 6 cm in diameter. Histological examination showed a pure LCNEC without any associated component, confirmed by immunohistochemistry. Metastatic tumour deposits with numerous lymphovascular emboli were identified in the cervix. A comprehensive review of literature along with the various differential diagnosis is discussed.

Abstract
Although the function of zinc finger and BTB domain containing 16 (ZBTB16) in spermatogenesis is well documented, expression of ZBTB16 in germ cell tumors has not yet been studied. The aim of this study was to investigate the immunohistochemical expression and diagnostic utility of ZBTB16 in germ cell tumors. A total of 67 adult germ cell tumors were studied (62 testicular germ cell tumors, 2 ovarian yolk sac tumors, 1 mediastinal yolk sac tumor, and 2 retroperitoneal metastatic yolk sac tumors). The 62 testicular primary germ cell tumors are as follows: 34 pure germ cell tumors (20 seminomas, 8 embryonal carcinomas, 2 teratomas, 1 choriocarcinoma, 1 carcinoid, and 2 spermatocytic tumors) and 28 mixed germ cell tumors (composed of 13 embryonal carcinomas, 15 yolk sac tumors, 15 teratomas, 7 seminomas, and 3 choriocarcinomas in various combinations). Thirty-five cases contained germ cell neoplasia in situ. Yolk sac tumor was consistently reactive for ZBTB16. Among the 15 testicular yolk sac tumors in mixed germ cell tumors, all displayed moderate to diffuse ZBTB16 staining. ZBTB16 reactivity was present regardless of the histologic patterns of yolk sac tumor and ZBTB16 was able to pick up small foci of yolk sac tumor intermixed/embedded in other germ cell tumor subtype elements. Diffuse ZBTB16 immunoreactivity was also observed in 2/2 metastatic yolk sac tumors, 1/1 mediastinal yolk sac tumor, 2/2 ovarian yolk sac tumors, 2/2 spermatocytic tumors, 1/1 carcinoid, and the spermatogonial cells. All the other non-yolk sac germ cell tumors were nonreactive, including seminoma (n=27), embryonal carcinoma (n=21), teratoma (n=17), choriocarcinoma (n=4), and germ cell neoplasia in situ (n=35). The sensitivity and specificity of ZBTB16 in detecting yolk sac tumor among the germ cell tumors was 100% (20/20) and 96% (66/69), respectively. In conclusion, ZBTB16 is a highly sensitive and specific marker for yolk sac tumor.

Abstract
Although most malignant lymphadenopathy in the neck represent lymphomas or metastases from head and neck primary tumors, occasionally, metastatic disease from remote, usually infraclavicular, sites presents as cervical lymphadenopathy with or without an obvious primary tumor. In general, these tumors metastasize to supraclavicular lymph nodes, but occasionally may present at an isolated higher neck level. A search for the primary tumor includes information gained by histology, immunohistochemistry, and evaluation of molecular markers that may be unique to the primary tumor site. In addition, 18F-fluoro-2-deoxyglocose positron emission tomography combined with CT (FDG-PET/CT) has greatly improved the ability to detect the location of an unknown primary tumor, particularly when in a remote location. Although cervical metastatic disease from a remote primary site is often incurable, there are situations in which meaningful survival can be achieved with appropriate local treatment. Management is quite complex and requires a truly multidisciplinary approach. © 2015 Wiley Periodicals, Inc. Head Neck 38: E2374-E2385, 2016.

Abstract
A comprehensive pathological report is essential for optimal patient management, cancer staging and prognostication. In many countries, proforma reports are used but these vary in their content. The International Collaboration on Cancer Reporting (ICCR) is an alliance formed by the Royal College of Pathologists of Australasia, the Royal College of Pathologists of the United Kingdom, the College of American Pathologists, the Canadian Partnership Against Cancer and the European Society of Pathology, with the aim of developing an evidence-based reporting data set for each cancer site. This will reduce the global burden of cancer data set development and reduplication of effort by different international institutions that commission, publish and maintain standardised cancer reporting data sets. The resultant standardisation of cancer reporting will benefit not only those countries directly involved in the collaboration but also others not in a position to develop their own data sets. We describe the development of a cancer data set by the ICCR expert panel for the reporting of primary ovarian, fallopian tube and peritoneal carcinoma and present the 'required' and 'recommended' elements to be included in the report with an explanatory commentary. This data set encompasses the recent International Federation of Obstetricians and Gynaecologists staging system for these neoplasms and the updated World Health Organisation Classification of Tumours of the Female Reproductive Organs. The data set also addresses issues about site assignment of the primary tumour in high-grade serous carcinomas and proposes a scoring system for the assessment of tumour response to neoadjuvant chemotherapy. The widespread implementation of this data set will facilitate consistent and accurate data collection, comparison of epidemiological and pathological parameters between different populations, facilitate research and hopefully will result in improved patient management.

Abstract
Metastatic adenocarcinomas to the ovary can show morphologically innocuous areas simulating primary benign lesions or borderline tumors. Ruling out a metastasis can be a difficult issue for pathologists, especially when facing with cystic tumors. Because of the important clinical implications of differentiating metastatic adenocarcinomas from primary ovarian tumors, the integration of clinical, pathological, and immunohistochemical features is warranted, primarily in case of mucinous adenocarcinomas. Vice versa, the synchronous presence of a metastasis and a primary in the same ovary is virtually excluded as a very unlikely eventuality. Here, we describe a case of metastatic adenocarcinoma from the jejunum colliding with a seromucinous borderline tumor in the same ovary, an unreported eventuality so far.

Abstract
The distinction between primary and secondary (metastatic) ovarian tumors is essential for the selection of appropriate surgical interventions, chemotherapeutic treatment and prognostic evaluation for the patient. Metastatic tumors of the ovary range between 5 % and 30 %. The majority of ovarian metastases in Europe and North America derive from colorectal (25-50 %) and breast cancers (8-25 %). A major issue is the differential diagnosis of mucinous tumors. Major features favoring metastasis include bilaterality, size < 10 cm, ovarian surface involvement, extensive intra-abdominal spread, and infiltrative growth within the ovary involving the corpus albicans and corpora lutea. An algorithm using bilaterality and tumor size (cut-off 10 cm) allows correct categorization in approximately 85 % of the cases. Although immunohistochemistry (especially CK7 and CK20 in mucinous tumors) using a panel of antibodies plays a valuable role and is paramount in the diagnosis, the results must be interpreted with caution and within the relevant clinical and histopathological context. It is necessary to note that the correct diagnosis of ovarian metastases always needs interdisciplinary and multidisciplinary approaches.

Abstract
Clear cell carcinoma of the ovary (CCC) is a histologic subtype of epithelial ovarian cancer with a distinct clinical behavior. There are marked geographic differences in the prevalence of CCC. The CCC is more likely to be detected at an early stage than high-grade serous cancers, and when confined within the ovary, the prognosis is good. However, advanced disease is associated with a very poor prognosis and resistance to standard treatment. Cytoreductive surgery should be performed for patients with stage II, III, or IV disease. An international phase III study to compare irinotecan/cisplatin and paclitaxel/carboplatin as adjuvant chemotherapy for stage IIV CCC has completed enrollment (GCIG/JGOG3017). Considering the frequent PIK3CA mutation in CCC, dual inhibitors targeting PI3K, AKT in the mTOR pathway, are promising. Performing these trials and generating the evidence will require considerable international collaboration.

Abstract
AIM Ovarian steroid cell tumors, not otherwise specified (SCT-NOS) are very rare neoplasms. No large study has been performed in Pakistan to establish the clinicopathological spectrum and immunohistochemical behavior in our region. The purpose of our study was to determine the various clinicopathological and immunohistochemical features of ovarian SCT-NOS along with follow-up in our institution. METHODS This was a retrospective observational study. The study was conducted in the Section of Histopathology, Aga Khan University Hospital, Karachi, Pakistan. All reported cases of ovarian SCT-NOS occurring during January 1992 to August 2013 were retrieved. The slides were reviewed and patient demographics, and clinical and pathological features were noted with proforma software. SPSS version 19 was used for all analyses. Data is expressed as absolute values and percentages. RESULTS A total of 12 SCT-NOS (2.3%) out of 528 ovarian sex cord stromal tumors were retrieved. The age range was 3-70 years, with mean of 40.75 years. The tumors ranged 2.5-13 cm in size, with a mean size of 6.1 cm. One patient had bilateral tumors. All of the tumors were positive for inhibin and calretinin. Four tumors were negative for Mic-2 (CD99). In two patients, the tumor recurred. Only one patient who had worse pathological features received adjuvant chemotherapy. CONCLUSION Steroid cell tumors are very rare ovarian tumors in the Pakistani population, mostly presenting in adulthood. Diverse histological differentials exist so special stains and immunohistochemical stains are needed to distinguish these from other tumors.

Abstract
Presence of signet ring cells in ovarian neoplasms are commonly encountered in Krukenberg tumours of ovary. Unusual presence in primary ovarian mucinous tumours may create a diagnostic difficulty. To the best of our knowledge only very few such cases have been reported in the literature indicating their rarity. We report a case of primary ovarian mucinous carcinoma with signet ring cells. The purpose of this presentation is to sensitize the pathologists to consider primary mucinous carcinoma as a differential diagnosis in tumours with signet ring cells.

Abstract
Background: Considering the high prevalence of female genital tract neoplasms, non-specific nature of the initial symptoms, higher possibility of metastasis by the time of diagnosis, importance of differentiating metastatic Mullerian tumors or metastatic breast cancer in the female genital tract, especially in the ovary, and lack of diagnostic markers with high sensitivity and specificity, the purpose of the current study was to evaluate the utility of Paired box protein8 (PAX8) expression in Mullerian and non-Mullerian neoplasms. Materials and Methods: In this descriptive–analytic, cross-sectional study, paraffin-embedded tissues of patients with definitive pathologic diagnosis of Mullerian and non-Mullerian tumors were selected. PAX8 immunohistochemical (IHC) staining was performed for all selected blocks. Immunopositivity of the slides for PAX8 was reviewed. It was defined as the presence of nuclear staining in at least 10% of the tumor cell nuclei. Results: Thirty-seven Mullerian (including 18 ovarian epithelial tumors, 17 endometrial carcinoma and two endocervical adenocarcinoma) and 37 non-Mullerian tumors were studied for PAX8 expression. Twenty-nine of 37 (78.4%) and one of 37 (2.7%) of the Mullerian and non-Mullerian tumors were positive for PAX8, respectively. The sensitivity and specificity of PAX8 by IHC for differentiation of Mullerian from non-Mullerian tumors was 78.4% and 97.3%, respectively. Conclusion: Our findings indicated that PAX8 could be used as a useful IHC marker for diagnosing Mullerian tumors. It has moderate to high sensitivity, but high specificity, for diagnosing carcinomas of Mullerian origin.
