Abstract
In two separate reviews, we review the time-honored but still frequently challenging features of ovarian sex cord-stromal tumors, and also emphasize new developments including unusual morphologic appearances that, despite the relative rarity of many of the tumors, result in a disproportionate number of differential diagnostic problems, variant immunohistochemical profiles, and specific molecular and syndromic associations. These neoplasms are also of historical interest as current knowledge is still based in significant part on the contributions of 2 giants of gynecologic pathology, Dr Robert Meyer and Dr Robert E. Scully. In part I, we present the major clinical, pathologic, and genomic features of the pure ovarian stromal tumors including comments on differential diagnosis and briefly note significant historical contributions. In part II we will discuss pure sex cord and sex cord-stromal tumors.

Abstract
Sex cord tumor with annular tubules (SCTAT) is a rare ovarian tumor. It belongs to sex cord and stromal tumor of the ovary and represents less than 1% of cases. It includes two forms: the first one associated with Peuz-Jeghers syndrome and the second sporadic. We report 4 cases of SCTAT collected at the department of pathology of Salah Azaiez Institute of Tunis over the 12 last years. The age ranged from 10 to 32 years. Symptoms were non specific except for one case revealed by precocious puberty. One patient had Peutz-Jeghers syndrome associated. Tumors were unilateral. Gross findings showed often a solid tumor with yellow cut surface. Their size ranged from 0.5cm to 28cm. Their morphological features were characteristic. Immunohistochemistry showed that tumor cells expressed inhibin and claretinin. The treatment was surgical, often conservative. The diagnosis of malignancy wasn't focused on histological features, but on tumor extension, clinical course, and presence of metastases. Evolution was often favorable. We also performed a systematic review of the literature that identified 166 cases. Features of these cases were studied. We also compared these features between sporadic and syndromic forms and between benign and malignant forms. In conclusion, SCTAT is a rare tumor, usually benign. Its diagnosis is based on histological examination. There is a malignant potential especially in sporadic forms, estimated at 20%. Treatment is most often conservative, based on oophorectomy.

Abstract
OBJECTIVE Ovarian fibromas are benign, sex cord-stromal tumors occurring in both peri- and post-menopausal women. Generally, these tumors are non-functional and do not produce hormones. However, this case report proves the first case of steroid hormone synthesis in an ovarian fibroma by immunohistochemistry. CASE REPORT A 77-year-old post-menopausal woman presented with a left ovarian tumor, abnormal endometrial thickness, and high levels of estradiol (E2). The tumor was found to be a fibroma, which was positive for alpha-inhibin. We examined estrogen-producing enzymes using immunohistochemistry. The tumor was positive for estrogen receptor, progesterone receptor, 17β-hydroxysteroid dehydrogenase (HSD)-1, adrenal 4 binding protein/steroidogenic factor 1, 17β-HSD-5, steroid sulfatase, and P450c17. CONCLUSION This case study shows that E2 can be locally produced from circulating inactive steroids, by estrogen-producing enzymes. This is the first report of steroid hormone synthesis in an ovarian fibroma.

Abstract
Sex cord-stromal tumors (SCSTs), generally referred to as granulosa cell tumors (GCTs) or granulosa-theca cell tumors (GTCTs) in equids, show complex compositions and variable numbers of hormone-producing cells. These tumors can be difficult to diagnose, especially in early stages. Therefore, we tested a panel of antibodies for vimentin, smooth muscle actin, laminin, Ki-67, E-cadherin, calretinin, moesin, p-ezrin, AMH, and aromatase, markers used for tumor composition and classification, progression, and prognosis in human SCSTs, on an exemplary grapefruit-size equine GCT within the left ovary of a 13-year-old mare with stallion-like behavior and elevated testosterone levels in comparison with normal ovarian tissue. The tumor showed a low proliferation rate and prominent moesin and p-ezrin staining in granulosa cells. E-cadherin, calretinin, aromatase, and AMH are suggested to be potential markers for different cell components of equine SCSTs that can support tumor diagnosis and classification.

Inhibin Alpha Expression in Human Tumors: A Tissue Microarray Study on 12,212 Tumors. Biomedicines 2022; 10:biomedicines10102507.

Abstract
As a result of its expression in corresponding normal cell types, inhibin alpha (INHA) is used as an immunohistochemical marker for adrenocortical neoplasms and testicular or ovarian sex cord stromal tumors. However, other tumors can also express INHA. To comprehensively determine INHA expression in cancer, a tissue microarray containing 15,012 samples from 134 different tumor types and subtypes was analyzed by immunohistochemistry. INHA positivity was found in 72 of 134 tumor categories, including 26 categories with ≥1 strongly positive case. A moderate to strong INHA positivity was found in 100% of 37 granulosa cell tumors of the ovary, 100% of 43 other sex cord stromal tumors of the ovary/testis, 100% of 31 granular cell tumors, 78.5% of 28 adenomas, 44% of 25 carcinomas of the adrenal cortex, and 46.7% of 15 pancreatic acinar cell carcinomas. At least a weak INHA positivity was seen in <33% of cases of 46 additional tumor entities. In summary, these data support the use of INHA antibodies for detecting sex cord stromal tumors, granular cell tumors, and adrenocortical neoplasms. Since INHA can also be found in other tumor entities, INHA immunohistochemistry should only be considered as a part of any panel for the distinction of tumor entities.

Abstract
DICER1 syndrome is a tumor predisposition syndrome in which patients are at an increased risk of developing a wide variety of benign and malignant neoplasms with a hallmark constellation of pediatric pleuropulmonary blastoma, cystic nephroma, and thyroid lesions. DICER1 encodes an RNA endoribonuclease that is crucial to the processing of microRNA and may play a role in the maturation of Müllerian tissue. Within the gynecologic tract, germline mutations in DICER1 are associated with an array of rare tumors, including Sertoli-Leydig cell tumor, embryonal rhabdomyosarcoma of the cervix, gynandroblastoma, and juvenile granulosa cell tumor, which typically present in childhood, adolescence, or early adulthood. In addition, somatic DICER1 mutations have been described in rare gynecologic tumors such as adenosarcoma, Sertoli cell tumor, ovarian fibrosarcoma, cervical primitive neuroectodermal tumor, carcinosarcoma, and germ cell tumors. In light of the significant association with multiple neoplasms, genetic counseling should be considered for patients who present with a personal or family history of these rare DICER1-associated gynecologic tumors. This review highlights the most current understanding of DICER1 genetic alterations and describes the clinical, histopathologic, and immunohistochemical features and differential diagnoses for gynecologic tumors associated with DICER1 mutation.

Abstract
Epithelial ovarian cancer (EOC) is the most lethal gynecologic malignancy and has a unique metastatic route using ascites, known as the transcoelomic root. However, studies on ascites and contained cellular components have not yet been sufficiently clarified. In this review, we focus on the significance of accumulating ascites, contained EOC cells in the form of spheroids, and interaction with non-malignant host cells. To become resistant against anoikis, EOC cells form spheroids in ascites, where epithelial-to-mesenchymal transition stimulated by transforming growth factor-β can be a key pathway. As spheroids form, EOC cells are also gaining the ability to attach and invade the peritoneum to induce intraperitoneal metastasis, as well as resistance to conventional chemotherapy. Recently, accumulating evidence suggests that EOC spheroids in ascites are composed of not only cancer cells, but also non-malignant cells existing with higher abundance than EOC cells in ascites, including macrophages, mesothelial cells, and lymphocytes. Moreover, hetero-cellular spheroids are demonstrated to form more aggregated spheroids and have higher adhesion ability for the mesothelial layer. To improve the poor prognosis, we need to elucidate the mechanisms of spheroid formation and interactions with non-malignant cells in ascites that are a unique tumor microenvironment for EOC.

Therapeutic Role of Annona muricata Fruit and Bee Venom Against MNU-Induced Breast Cancer in Pregnant Rats and its Complications on the Ovaries. BREAST CANCER (DOVE MEDICAL PRESS) 2021; 13:431-445. [PMID: 34267553 PMCID: PMC8275159 DOI: 10.2147/bctt.s306971] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 02/17/2021] [Accepted: 04/08/2021] [Indexed: 11/23/2022]
Abstract
AIM To evaluate the potential therapeutic role of Annona muricata (graviola) fruit and bee venom (BV) against N-methylnitrosourea (MNU)-induced breast cancer in pregnant female rats and complications in the ovaries. METHODS A total of 24 female rats were induced with a single dose of MNU (50 mg/kg body weight). After confirmation of positive tumor marker, female rats were placed with the males for mating. The pregnant rats were randomly divided into four groups (n=6): MNU-induced only (group 1), MNU-induced rats and supplemented with A. muricata 200 mg/kg diet (group 2), MNU-induced and treated with two doses of BV 75 μg/kg (group 3), and MNU-induced and treated with both A. muricata and BV (group 4). RESULTS In group 1, the breast tissue of mothers revealed pronounced cellular hyperplasia and histopathological signs. Also, the ovarian tissue of mothers and their offspring displayed deleterious histological changes. In groups 2 and 4, histopathological signs and cellular hyperplasia markedly disappeared in breast tissue. However, the histopathological signs induced by MNU in the ovarian tissue reversed to normal in groups 2-4. Also in groups 2-4, levels of serum MMP1, NFκB, and TNFα significantly decreased, and serum caspase 3 significantly increased either in mother rats or their offspring compared to the MNU-alone group. Levels of serum MDA significantly decreased; however, levels of serum antioxidants (CAT and SOD) significantly increased in all groups 2-4 compared to MNU-alone group. CONCLUSION A. muricata has a more powerful therapeutic role than BV against MNU-induced breast cancer in rats; however, both have a powerful ameliorative role against ovarian histopathological alterations induced by MNU. Such ameliorative effects of A. muricata and BV are mainly attributed to their antioxidant, anti-inflammatory, and antiproliferative constituents.

Immunohistochemical Characterization of 120 Testicular Sex Cord-Stromal Tumors With an Emphasis on the Diagnostic Utility of SOX9, FOXL2, and SF-1. Am J Surg Pathol 2021; 45:1303-1313.

Abstract
Sex cord-stromal tumors (SCSTs) account for the second most common category of testicular neoplasms and include several entities that may show overlapping morphologies and present diagnostic challenges. We analyzed a cohort of 120 testicular SCSTs and investigated the diagnostic utility of SRY-box transcription factor 9 (SOX9), forkhead box protein L2 (FOXL2), and steroidogenic factor 1 (SF-1) immunohistochemical stains. The results were compared with the more commonly used SCST markers, inhibin α, calretinin, and Wilms' tumor 1 (WT1). SF-1 was overall the most sensitive stain (91%), followed by inhibin α (70%), calretinin (52%), FOXL2 (50%), SOX9 (47%), and WT1 (37%), but sensitivities varied by tumor type. SOX9 and calretinin were more commonly positive in sex cord elements versus stromal elements (62% vs. 27% and 47% vs. 9%, respectively), whereas FOXL2 was more commonly positive in stromal elements versus sex cord elements (100% vs. 55%) when excluding Leydig cell tumors from the stromal category. Although no individual stain was diagnostically specific, some immunophenotypic patterns were noted that may help in the subclassification of SCSTs. We conclude that SOX9, FOXL2, and SF-1 are useful immunohistochemical stains for confirming sex cord-stromal differentiation in testicular tumors and provide increased sensitivity as well as additional diagnostic information, especially when combined with the more commonly used inhibin α, calretinin, and WT1 immunostains. Although morphology is paramount for subclassification of SCSTs, knowledge of certain immunohistochemical patterns may be helpful for diagnostically challenging cases.

Abstract
Sertoli-Leydig cell tumors (SLCTs) are rare ovarian sex cord-stromal neoplasms. The only known recurrent genetic abnormality is DICER1 mutation, with rare mutations reported in FOXL2. We set out to establish a molecular classifier using DICER1 and FOXL2 somatic mutation status and clinicopathologic features in 42 SLCTs. Five tumors (12%) were well differentiated, 31 (74%) moderately differentiated, and 6 (14%) poorly differentiated. Eight (19%) had heterologous elements, and 2 (5%) showed retiform differentiation; all 10 were moderately differentiated. DICER1 RNase IIIb domain mutations were identified in 18/41 (44%; 17 moderately, 1 poorly differentiated), including all cases with retiform or heterologous elements. FOXL2 c.402C>G (p.C134W) mutation was identified in 8/42 (19%) tumors (5 moderately, 3 poorly differentiated). DICER1 and FOXL2 mutations were mutually exclusive. Median age for the cohort was 47 years (range, 15 to 90 y). Patients with DICER1 mutations were younger (median, 24.5 y; range, 15 to 62 y) than patients with FOXL2 mutation (median, 79.5 y; range, 51 to 90 y) (P<0.0001). Nine of 10 tumors with retiform or heterologous elements occurred in premenopausal patients (median, 26.5 y; range, 15 to 57 y). Patients with tumors that were wild type for DICER1 and FOXL2 (15/42, 37%) had an intermediate age (median, 51 y; range, 17 to 74 y). All tumors were FOXL2 positive by immunohistochemistry. Patients with FOXL2 mutation trended toward presenting more often with abnormal bleeding (P=0.13); DICER1-mutant patients trended toward having more androgenic symptoms (P=0.22). Our data suggest at least 3 molecular subtypes of SLCT with distinct clinicopathologic features: DICER1 mutant (younger, more androgenic symptoms, moderately/poorly differentiated, retiform or heterologous elements), FOXL2 mutant (postmenopausal, abnormal bleeding, moderately/poorly differentiated, no retiform or heterologous elements), and DICER1/FOXL2 wild type (intermediate age, no retiform or heterologous elements, including all well-differentiated tumors).

Identification of recurrent FHL2-GLI2 oncogenic fusion in sclerosing stromal tumors of the ovary. Nat Commun 2020; 11:44.

Abstract
Sclerosing stromal tumor (SST) of the ovary is a rare type of sex cord-stromal tumor (SCST), whose genetic underpinning is currently unknown. Here, using whole-exome, targeted capture and RNA-sequencing, we report recurrent FHL2-GLI2 fusion genes in 65% (17/26) of SSTs and other GLI2 rearrangements in additional 15% (4/26) SSTs, none of which are detected in other types of SCSTs (n = 48) or common cancer types (n = 9,950). The FHL2-GLI2 fusions result in transcriptomic activation of the Sonic Hedgehog (SHH) pathway in SSTs. Expression of the FHL2-GLI2 fusion in vitro leads to the acquisition of phenotypic characteristics of SSTs, increased proliferation, migration and colony formation, and SHH pathway activation. Targeted inhibition of the SHH pathway results in reversal of these oncogenic properties, indicating its role in the pathogenesis of SSTs. Our results demonstrate that the FHL2-GLI2 fusion is likely the oncogenic driver of SSTs, defining a genotypic–phenotypic correlation in ovarian neoplasms. Little is known about the genetics of sclerosing stromal tumor of the ovary, a rare type of sex cord-stromal tumor. Here, the authors use sequencing strategies to show that in a cohort of 26 tumor samples 65% carry a FHL2-GLI2 fusion gene and demonstrate in vitro that the fusion gene has oncogenic properties.

Abstract
Steroid cell tumour is a rare sex cord-stromal tumor of the ovary. It may produce steroids and is associated with testosterone secretion which causes symptoms like hair loss, hirsutism, and oligomenorrhea/amenorrhea due to hormonal activity and virilizing properties of tumor. In this article, we reported a 27-year-old woman who presented with hirsutism, hoarseness of voice, scalp hair fall, and amenorrhea for 8 years. Clinical and diagnostic evaluation revealed a left adnexal mass and elevated serum levels of testosterone and she was diagnosed as having a Sertoli Leydig cell tumour of ovary. She underwent left salpingooophorectomy and both histopathological examination and immunohistochemistry confirmed the diagnosis. Her serum testosterone levels normalized 3 days after the surgery and her menses resumed spontaneously a few months after the operation. In addition, we reviewed the literature on the epidemiology, clinical presentations, imaging and histological findings, and the treatment options on this disease.

Abstract
A uterine tumor resembling an ovarian sex cord tumor (UTROSCT) is a rare type of neoplasm that is almost thoroughly differentiated towards ovarian sex cord elements. Because of abnormal uterine bleeding, a 64-year-old postmenopausal woman received total abdominal hysterectomy with bilateral salpingo-oophorectomy. Under a microscope, the tumor cells showed an anastomosing fascicular and trabecular pattern with a reticular architecture. Immunohistochemistry showed that the tumor cells were positive for calretinin, Wilm’s tumor-1, and vimentin. A 33-year-old woman who suffered from menorrhagia, and was treated for bilateral salpingectomy, total abdominal hysterectomy, and bilateral ovarian biopsy, was also studied. Using histology, the patient was diagnosed with UTROSCT as shown by CD99, smooth muscle actin, calretinin, vimentin, and desmin expression. As a type of rare uterine tumor, UTROSCT can be diagnosed based on morphological and immunohistochemical conditions. Generally, these tumors are benign, but can easily relapse through incomplete resection. Hysterectomy should be performed after completion of family planning.

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
We report the case of a 15 years old teenage girl presenting with a primary amenorrhea and hypervirilisation symptoms. The clinical assessement found a 16cm wide heterogenous ovarian mass testosteronemia and alpha-foeto protein levels were increased. On gross exam the tumor was solid and cystic, multilocular containing serous and mucinous liquids. Microscopically, there was a sertoli cells rich solid area in which the cells had a trabecular and nested organization with Leydig cells between them and there was also a cystic area made of glandular structures lined with an intestinal muco-secreting epithelium. Next to these area, there were Sertoli cells and an oedematous stroma. The immunostaining showed that the Sertoli cells expressed, among others, the inhibine and the glands expressed the cytokeratins 7 and 20. A Sertoli and Leydig cells tumor of intermediate differentiation with heterologous elements diagnostic was made. This is a rare tumor, representing less than 0.5% of ovary tumors. Well differentiated tumors are not frequent. In one third of the cases, there are hypervirilisation symptoms, the imaging exams will serve to narrow the diagnosis and to do a full work-up to establish an extension. There are several histologic sub types caracterised by the existence of retiforms structures or heterologous elements. There are no specific immunostainings, this will only help to narrow the diagnosis and rule out some hypothesis. There are no guidelines for the management of the patients, indeed each center has its own practices. Those tumors have quite a good prognosis thanks to their early diagnosis at a stade where they are still confined to the ovary.

Abstract
Sex cord-stromal tumours (SCSTs) consist of a heterogeneous group of neoplasms with diverse clinicopathological features and biological behaviour. They often present as a diagnostic challenge as they have varied and occasionally overlapping histomorphology and some may even mimic non-SCSTs. An accurate diagnosis is important for therapeutic and prognostic purposes. The use of a panel of immunohistochemical markers which are sensitive and specific for sex cord-stromal differentiation such as α-inhibin, calretinin, SF-1 and FOXL2, may be helpful in confirming the cellular lineage of these tumours, but is of limited utility in distinguishing between the different tumour types within this category. Additionally, the development of new therapeutic strategies in patients with SCSTs is also hampered by the infrequent occurrence of these neoplasms. Recent molecular analyses of some SCSTs has led to the discovery of novel molecular events, which may have important diagnostic, prognostic and therapeutic implications. The salient pathological features, management issues and recently described genetic aberrations in adult and juvenile granulosa cell tumours as well as Sertoli-Leydig cell tumours are discussed in this review, with particular emphasis on the clinical significance of FOXL2 and DICER1 mutations. An in-depth understanding of the molecular pathogenesis underlying SCSTs may aid in improving tumour classification and disease prognostication and also potentially lead to the discovery of more effective treatment strategies.

Abstract
Ovarian sex cord-stromal tumors arise from the stromal cells that surround and support the oocytes. Sertoli-Leydig cell tumors belong to this category of ovarian neoplasms. We present the case of a 38-year-old woman who was found to have a right ovarian mass. The mass was resected and diagnosed as Stage I Sertoli-Leydig cell tumor, retiform variant, following histopathologic and immunohistochemical examination. This case is unusual given the rarity of the retiform variant of Sertoli-Leydig cell tumor and the atypically older age of 38 years at presentation.

Abstract
Ovarian cancer is the fifth cause of cancer-related death in women and comprises a histologically and genetically broad range of tumours, including those of epithelial, sex cord-stromal and germ cell origin. Recent evidence indicates that high-grade serous ovarian carcinoma, clear cell carcinoma and endometrioid carcinoma primarily arise from tissues that are not normally present in the ovary. These histogenetic pathways are informing risk-reduction strategies for the prevention of ovarian and ovary-associated cancers and have highlighted the importance of the seemingly unique ovarian microenvironment.

Abstract
Sarcoma arising in the mammary gland is a rare tumor in dogs, and primary liposarcoma with metastatic behavior has never been previously reported among canine mammary tumors. A 14-year old female poodle had a mammary mass diagnosed as pleomorphic liposarcoma. Two years following surgical removal, the tumor recurred in the mammary gland with lymph node metastases. In addition, a sex-cord stromal tumor was identified in the ovary. Immunohistochemistry was performed on both tumors that were positive for oestrogen and progesterone receptors. Moreover, the ovarian tumor was positive for calretinin. This is the first report to the authors' knowledge, of the co-occurrence of a pleomorphic liposarcoma of the mammary gland and an ovarian sex-cord stromal (gonadostromal) tumor in the dog.

Abstract
Sertoli–Leydig cell tumors are rare sex cord-stromal neoplasms that account for <0.2% of ovarian tumors. These tumors with a retiform pattern pose difficult diagnostic problems, with the majority of being misinterpreted as serous papillary cystadenocarcinoma and endodermal sinus tumor. We report an 8-year-old female patient presented to our institution with a huge mass and pain in the lower abdomen and recurrence in the 10th months following the first operation. Only four cases of Sertoli–Leydig cell tumors have been reported under age of the eight years in the literature so far. It is difficult to define the stage and the morphology of Sertoli–Leydig cell tumors with retiform pattern in children and chemotherapy or radiotherapy administration is contraversial. However, fertility sparing surgeries should be considered as a first treatment choice on the time of the diagnosis and the recurrence.

Abstract
Steroid cell tumor not otherwise specified (NOS) is a rare subtype of sex cord stromal tumor of the ovary and contributes less than 0.1% of all ovarian neoplasms. The majority of tumors occur in pre-menopausal women (mean age: 43 years), in which 56-77% of patients present with virilization due to excess testosterone. An 80-year-old woman with worsening alopecia and excessive growth of coarse hair on abdomen and genital area was found to have elevated serum testosterone level (462 ng/mL). Radiologic studies were consistent with bilateral adrenal adenomas. Bilateral adrenal venous sampling ruled out the adrenal gland as origin of hormone secretion. A diagnostic and therapeutic bilateral salpingo-oophorectomy confirmed steroid cell tumor NOS of the left ovary. Post-operatively, the patient had complete resolution of her symptoms and normalization of testosterone level. Our case emphasizes the importance of a clinical suspicion for an occult testosterone secreting ovarian tumor in a symptomatic patient without obvious ovarian mass on imaging.

Abstract
Peutz-Jeghers syndrome (PJS), in most cases, is attributed to mutation in STK11/LKB1 and is clinically characterized by gastrointestinal hamartomatous polyposis, mucocutaneous pigmentation, and predisposition to certain neoplasms. There are currently no recommended gynecologic screening or clinical surveillance guidelines beyond those recommended for the general population; however, cervical cytology samples must be examined with a high level of suspicion for cervical adenocarcinoma. It is considered prudent to note the established association with PJS and recommend referral for genetic counseling. Complete surgical excision after a diagnosis of atypical lobular endocervical glandular hyperplasia is recommended.

Abstract
Thecoma is a rare ovarian tumor, presenting usually in postmenopausal women as unilateral, benign, solid lesion. About 15% of affected patients develop endometrial hyperplasia (EH) and 20% are diagnosed with endometrial cancer. In this case report, we present 60-year-old women admitted because of recurrent spotting of 5 years duration, which started 1 year after menopause. In history, the patient underwent three times curettage procedures and once (1 year before admission) had estradiol levels typical for reproductive-age women. At admission, we found elevated serum levels of estradiol (222.5 pg/ml) and a small mass in the right ovary. The markers of germ cell tumors were negative. After the initial diagnosis, the patient was qualified for total abdominal hysterectomy with bilateral salpingo-oophorectomy. The histopathological examination and immunohistochemical staining confirmed the thecoma diagnosis. In follow-up examination after 8 weeks, we found decreased serum estradiol levels and relief of the symptoms. In conclusion, we want to underline that in cases of EH, especially in patients with a history of recurrences, the special attention should be paid for differential diagnosis. In such cases, the estrogen-secreting tumors should be excluded.

Abstract
Calretinin is a member of the EF-hand family of calcium-binding proteins. Because its expression is highly restricted to mesotheliomas, calretinin is, at present, the most commonly used positive mesothelioma marker that is most often recommended to be included in the various immunohistochemical panels used to assist in the differential diagnosis of these tumors. Calretinin expression has also been reported to be commonly expressed in a wide variety of other neoplasms, including sex cord-stromal tumors, adrenal cortical neoplasms, olfactory neuroblastomas, Schwann cell tumors, cardiac myxomas, and ameloblastomas. This article reviews the information that is currently available on calretinin expression in tumors and on its application as an immunohistochemical marker in diagnostic pathology.

Abstract
Tumor-initiating cells are thought to share features with normal somatic stem cells. In mice, stem cells at the ovarian hilum have been shown to express the stem cell marker, aldehyde dehydrogenase isoform 1A1 (ALDH1A1), and are prone to malignant transformation. The potential relevance of this finding to humans has not been established. In this study, we used immunohistochemistry to assess the distribution of ALDH1A1 staining in the epithelium of human fallopian tubes, with particular reference to the transition of tubal epithelium to mesothelium (ie, tubal-mesothelial junction), ovarian surface epithelium, as well as putative precursors of ovarian high-grade serous carcinoma, namely, serous tubal intraepithelial carcinoma and 'p53 signatures,' and overt serous carcinoma. Expression of ALDH1A1 was detected in both secretory and ciliated tubal epithelial cells, tubal-mesothelial junctions and ovarian surface epithelium, but was absent in serous tubal intraepithelial carcinoma and p53 signatures. Positive staining in high-grade serous carcinoma, when present, was typically limited to rare tumor cells. In silico analyses of the mRNA expression data set from The Cancer Genome Atlas revealed downregulation of ALDH1A1 transcripts in high-grade serous carcinoma relative to normal tubal epithelium, and no association between ALDH1A1 expression levels and overall survival. Our results do not support ALDH1A1 as a specific marker of stem cells in human fallopian tube and demonstrate that its loss of expression is an early event in the development of high-grade serous carcinoma.

Abstract
Context
Immunohistochemistry has assumed an increasing role in the identification and characterization of gynecologic disorders including lesions with deceptively bland morphology, uncommon and underdiagnosed neoplasms, and neoplasms with specific genetic alterations associated with overexpression or loss of expression of specific proteins. The diagnostic accuracy has been significantly improved owing to the discovery and increasing experience with the tumor-associated biomarkers, and the increasing demand for precise tumor classification to assess suitability for the expanding therapeutic modalities including clinical trials.
Objective
To differentiate lesions of the gynecologic tract through the use of effective immunohistochemical panels.
Data Sources
Literature review and authors' personal practice experience.
Conclusions
The application of diagnostic and prognostic immunohistochemical panels has enabled pathologists to better guide therapeutic decisions and to better predict the clinical outcome. It is now well established that the use of ancillary testing, including immunohistochemistry, has a significant power in the identification, differentiation, and classification of reactive, premalignant, and malignant gynecologic disorders. This article discusses the utilities and pitfalls of the commonly used immunohistochemical markers in the context of overlapping morphologic features encountered in the uterus, ovaries, and fallopian tubes.

Abstract
Fibrothecoma accounts for 3-4% of all ovarian neoplasms; it is usually hormonally inactive, but can be estrogenic or sometimes androgenic (11%); it is rare under 30 years. In a very few cases, minor sex cord elements (less than 10% of the tumor area) are present; therefore, it is considered as a separate subgroup of stromal tumors. The importance of immunohistochemistry in recognizing this kind of tumor has been fully documented, with variable results on inhibin staining, but specific positivity for calretenin in such cases. We report here the rare case of a 13-year-old child with ovarian fibrothecoma and minor sex cord stromal elements, who showed negativity for inhibin and positivity for calretenin.

Clinical characteristics and outcomes of uterine tumors resembling ovarian sex-cord tumors (UTROSCT): a systematic review of literature. Eur J Obstet Gynecol Reprod Biol 2014; 181:163-70. [PMID: 25150955 DOI: 10.1016/j.ejogrb.2014.07.050] [Citation(s) in RCA: 48] [Impact Index Per Article: 4.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/21/2014] [Revised: 07/19/2014] [Accepted: 07/29/2014] [Indexed: 12/14/2022]
Abstract
Uterine tumor resembling ovarian sex-cord tumors (UTROSCT) is an extremely rare type of uterine tumor, and its clinical characteristics are not fully understood. A systematic literature search was conducted in PubMed and MEDLINE using the keywords, "uterine tumors resembling ovarian sex cord tumors", limited to case reports. Clinico-pathological characteristics and survival data were abstracted and evaluated for the analysis. Among 43 cases reporting UTROSCT, Type I (endometrial stromal tumors with sex cord-like elements, ESTSCLE) and Type II (classic UTROSCT) were reported in 5 (11.6%) and 17 (39.5%), respectively, and nearly half of reported UTROSCT did not subcategorize the histology pattern into Type I or II (unspecified, n=21, 48.8%). Mean age was 52.2. The two most common symptoms were postmenopausal vaginal bleeding (44.2%) and abnormal menstruation (39.5%). The majority underwent total hysterectomy with adnexectomy (65.1%) followed by hysterectomy alone (18.6%) and tumor resection alone (14.0%). Mean tumor size was 6.2cm, and extra-uterine spread was seen in 7.0%. By immunohistochemistry, calretinin expression was significantly correlated with CAM5.2, inhibin, and progesterone receptor expression (all, p<0.05). In survival analysis, disease-free survival (DFS) rates for all 43 cases at 1, 2, and 5 years for all cases were 97.0%, 92.7%, and 69.7%, respectively. Among recurrent cases, median time to recur was 24 months (range 9-48). Decreased DFS was significantly associated with pelvic pain (2-year rate, 81.8% versus 94.7%, p=0.006), histology subcategory (Type I versus II, 23.8% versus 100%, p=0.006), tumor size ≥10cm (75.0% versus 100%, p=0.046), cervical/extra-uterine metastasis (46.7% versus 100%, p=0.024), and lymphovascular space involvement (50% versus 100%, p=0.002). Treatment patterns were not statistically associated with DFS (hysterectomy, p=0.28; and adnexectomy, p=0.38). When histology patterns were examined, Type II disease was associated with less aggressive tumor behavior when compared to Type I disease: extra-uterine spread (Type I versus II, 40% versus 5.9%, p=0.007) and lymphovascular space invasion (50% versus 6.7%, p=0.012). Among 17 cases of Type II disease, disease recurrence was reported in 1 (5.9%) case at 3 years after the initial treatment. In conclusion, our study showed that UTROSCT was often not subcategorized. Because classic UTROSCT has a distinct clinical outcome and characteristic histological patterns when compared to ESTSCLE, distinguishing UTROSCT from ESTSCLE is an integral component of the diagnosis. While classic UTROSCT typically has a favorable prognosis, it has been known to develop a late recurrence. If risk factors for recurrence are absent, both hysterectomy and mass resection alone are possible options for management.

Abstract
BACKGROUND Mesothelin, a mesothelial marker, has been found expressed in and as a potential treatment target of cholangioacarcinoma (CC). It is possible that CC may be derived from the cells sharing mesothelial markers. However, the expression of other mesothelial markers in CC is largely unknown. METHODS Thirty CC cases (10 extrahepatic and 20 intrahepatic) were retrieved from our institutional archive. The immunohistochemical study of Calretinin (DC8), WT1 (6F-H2), Lymphatic Endothelial Marker (D2-40), CK5/6 (D5/16 B4) and CK19 (b170) was done on formalin fixed paraffin embedded sections for 2-3 blocks of each case. We compared the expression levels between CC and normal bile duct (NBD) on the same block. RESULTS All of the CC and NBD are positive for CK19 (23/23) and negative for WT1 (0/23) and D2-40 (0/23), except one CC positive for D2-40(1/30, 3.3%) and one NBD positive for WT1 (1/23, 4.3%). Calretinin immunoreactivity was detected in 52.2% (12/23) of CC, but none in NBD (0/23). CK5/6 was also detectable in 73.3% (22/30) of CC and all NBD (30/30). Increased expression of calretinin and reduced expression of CK5/6 were more likely associated with CC than NBD (P < 0.001 and P = 0.002, respectively). The sequential staining pattern of positive calretinin and negative CK5/6 in calretinin negative cases has a sensitivity of 69.57% and a specificity of 100% for differentiating CC from NBD. CK5/6 expression was also more likely associated with well-differentiated CC (7/7 versus 12/20 in moderately differentiated, and 9/10 in poorly differentiated, P = 0.019) and extrahepatic CC (10/10 versus 12/20 in intrahepatic, P = 0.029), but there was no association between the calretinin expression and the CC grade or location. CONCLUSION Calretinin and CK5/6 immunohistochemical stains may be useful for diagnosing a CC. Their immunohistochemical results should be interpreted with caution in the cases with differential diagnoses of mesothelioma and CC. A full mesothelioma panel, including WT1 and/or D2-40, is recommended to better define a mesothelial lineage. The biology of calretinin and CK5/6 expression in CC is unclear, but might shed light on identifying therapeutic targets for CC.

Abstract
BACKGROUND Steroid cell tumors of ovary account for less than 0.1% of all ovarian tumors and these tumours may present at any age in association with interesting presentations related to hormonal activities. The subtype, not otherwise specified (NOS), is associated with androgenic changes in 56-77% and Cushing syndrome in 6-10%. Due to the rarity of available data regarding these tumors, little is known about their malignant potential and metastatic behaviour. We hereby report an unusual metastasis of steroid cell ovarian neoplasm presented with both Cushing syndrome and hyperandrogenemia. CASE PRESENTATION A 31-year-old woman, who had a past medical history of ovarian tumor resection (left ovarian thecoma was initially diagnosed at that time), presented with hirsutism, hypertension and menstrual disorder. Also, laboratory work-up revealed hypercortisolism and androgen excess. Computerized tomography (CT) of the abdomen showed abdominal paraaortic masses, multiple intrahepatic nodules and retroperitoneal lymph nodes enlargement. Positron emission tomography/computed tomography (PET/CT) scan demonstrated metastatic lesions. Her ovarian tumor sections were re-examined and pathology result was corrected to steroid cell tumor (NOS) associated with active cell growth and necrosis. Subsequent excision of metastatic lesions yielded clinical improvement promptly and metastasis of steroid cell tumor was confirmed by postoperative pathological studies. However, one year after the surgical management of metastasis, recurrence happened while radiotherapy was ineffective. The patient finally died of tumor metastatic recurrence. CONCLUSION This case reports a rare coexistence of Cushing syndrome and hyperandrogenemia which occurs based on metastasis of steroid cell ovarian neoplasm. It presents a real diagnostic challenge to both clinicians and pathologists. Therefore, it is very important to establish a final diagnosis by pathological studies along with clinical manifestations and imaging findings. Besides, it is necessary to improve follow-up of patients with this kind of tumors.

Abstract
Leydig cell tumour (LCT) is an uncommon tumour that typically occurs in the testis. Primary epididymal LCT is extremely rare. To the best of our knowledge, only two cases have been reported in the world literature. Herein, we report a case of primary epididymal LCT in a 41-year-old Chinese male. The patient presented with right epididymal swelling for 3 months without endocrine manifestations, including gynaecomastia and decreased libido. Scrotal ultrasound demonstrated a mass about 1.5 cm in diameter entirely in the cephalic region of right epididymis. No abnormality was found in his bilateral testes. The patient underwent total mass resection without post-operative therapy. Histological examination revealed that the well-circumscribed tumour was separated by conspicuous hyalinised fibrous stroma; the tumour cells were large and polygonal with round nuclei and abundant eosinophilic cytoplasm. Immunophenotypically, the tumour cells expressed four markers of sex cord differentiation (calretinin, melanA, CD99 and inhibin). There was no recurrence at 2-year follow-up. Our observation once again confirms that LCT could primarily occur in the epididymis, and we suppose that it probably originates from the ectopic Leydig cells. As little is known about the pathogenesis and prognosis for such a rare disease, accumulation of more pathological and clinical data can help to better interpret this tumour.

Abstract
Granulosa cell tumors are classified as juvenile and adult types. They may be misinterpreted as a yolk sac tumor when they exhibit a “reticular” growth pattern and contain prominent mitotic activity. In this study, the authors performed immunohistochemical stains for SALL4 and steroidogenic factor-1 (SF-1) on 27 cases of yolk sac tumors and 24 granulosa cell tumors. Nuclear stains for both antibodies were considered as positive and the intensity of staining was graded as negative, weak, moderate, and strong. All the yolk sac tumors were positive for SALL4 (100%) with moderate to strong grade staining and negative for SF-1 (100%). In contrast, all the granulosa cell tumors were positive for SF-1 (85% moderate to strong grade staining and 15% weak staining) and negative for SALL4 (100%). The difference was significant ( P < .01, Student’s t test). This result indicates that these 2 markers could be used to distinguish these 2 tumors in a difficult situation.

Abstract
We recently have demonstrated nuclear localization of E-cadherin in ovarian adult granulosa cell tumors (Histopathology 2011;58:423). The purpose of the present study is to investigate the diagnostic utility of E-cadherin nuclear staining for the differential diagnosis between ovarian adult granulosa cell tumor and its morphological mimics. Tissue samples taken from 81 ovarian tumors and 20 extraovarian tumors were immunohistochemically stained using monoclonal anti-E-cadherin antibody recognizing cytoplasmic domain (clone 36 supplied by BD Biosciences, San Jose, CA). The ovarian tumors consisted of 30 adult granulosa cell tumors, 3 Sertoli-stromal cell tumors, 14 fibrothecomas, 5 carcinoid tumors, 1 large cell neuroendocrine carcinoma, 18 endometrioid adenocarcinomas, and 10 poorly differentiated serous adenocarcinomas. Extraovarian tumors consisted of 16 uterine endometrial stromal neoplasms and 4 pulmonary small cell carcinomas. Only tumor cells with nuclear staining were considered positive in this study. Ninety percent of adult granulosa cell tumors, 67% of Sertoli-stromal cell tumors, 64% of fibrothecomas, 75% of endometrial stromal neoplasms, 75% of small cell carcinomas, and the one large cell neuroendocrine carcinoma showed E-cadherin nuclear expression, whereas all the ovarian carcinoid tumors, endometrioid adenocarcinomas, and poorly differentiated serous adenocarcinomas were negative. E-cadherin nuclear staining is useful in distinguishing between adult granulosa cell tumors and ovarian adenocarcinomas or carcinoid tumors. However, it is of limited use for distinguishing between adult granulosa cell tumors and endometrial stromal neoplasms or small cell carcinomas. E-cadherin should be included in the immunohistochemical panel for an accurate diagnosis of ovarian adult granulosa cell tumors.

Abstract
Introduction Steroid cell tumors are microscopically characterized by abundant eosinophilic or vacuolated cytoplasm that is often positive for fat stains. These tumors could be of ovarian or ectopic adrenal origin. We present a rare case of a steroid cell tumor arising from the pelvic mesentery. Case presentation A 31-year-old Asian woman was undergoing treatment for infertility and virilizing symptoms. She underwent laparoscopy followed by laprotomy for a suspected ovarian cyst/pelvic mass. During the laprotomy, a mass of 9 × 7 cm was detected in the pelvic mesentery. Microscopically, the tumor showed large cells arranged predominantly in sheets with abundant granular cytoplasm and large vesicular nuclei with prominent nucleoli. The tumor was seen infiltrating surrounding adipose tissue. Immunohistochemically, the tumor cells showed strong positivity for kertain, inhibin, vimentine, melan-A, neuron-specific enolase, chromogranin, and S-100 protein and focal positivity to epithelial membrane antigen. An MIB1 index showed 4% nuclear positivity. The tumor cells were negative for calretinin, desmin, and muscle actin. Considering the clinical findings, histomorphology, and immunohistochemistry, we made the diagnosis of extraovarian and extra-adrenal steroid cell tumor (not otherwise specified) of the pelvic mesentery. Conclusions We report an extremely rare case of an extraovarian and extra-adrenal steroid cell tumor of the pelvic mesentery. The tumor was a cause of virilizing symptoms and infertility in the patient. Surgical removal of the tumor reverted the symptoms of virilization, and the patient subsequently conceived. Steroid cell tumors should be considered in differential diagnosis among women presenting with infertility and symptoms of virilization.
