Abstract
Uterine tumor resembling ovarian sex-cord tumor (UTROSCT) is a rare form of uterine mesenchymal neoplasm. Although UTROSCT generally exhibits benign behavior with a favorable prognosis, this neoplasm is nevertheless classified as being of uncertain malignant potential, given its low rate of recurrence and the fact that it rarely produces metastases (e.g., in the lymph nodes, epiploic appendix, omentum, small bowel, subcutaneous tissue, lungs). Its histogenesis is also uncertain. Typically, UTROSCT occurs in peri-menopausal or menopausal women, but it can sometimes be observed in young women. Usually, this neoplasm can be found in the uterine corpus as a nodular intramural lesion, while it is less frequently submucosal, subserosal, or polypoid/intracavitary. UTROSCT can cause abnormal bleeding, pelvic pain, enlarged uterus, and mass sensation, but sometimes it is found purely by chance. This neoplasm can be considered polyphenotypic on morphological, immunohistochemical, and genetic analyses. Generally, upon microscopic examination, UTROSCT shows a predominant pattern of the cords, nests, and trabeculae typical of sex-cord tumors of the ovary, while immunohistochemically it is characterized by a coexpression of epithelial, smooth muscle, and sex-cord markers. The aim of this review is to report clinical and pathological data and genetic alterations to establish their impact on the prognosis and management of patients affected by this rare entity.

Uterine Tumors Resembling Ovarian Sex Cord Tumors (UTROSCTs): A Scoping Review of 511 Cases, Including 2 New Cases. MEDICINA (KAUNAS, LITHUANIA) 2024; 60:179. [PMID: 38276058 PMCID: PMC10820159 DOI: 10.3390/medicina60010179] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 12/02/2023] [Revised: 01/10/2024] [Accepted: 01/15/2024] [Indexed: 01/27/2024]
Abstract
Uterine Tumors Resembling Ovarian Sex Cord Tumors (UTROSCTs) are rare uterine mesenchymal neoplasms with uncertain biological potential. These tumors, which affect both premenopausal and postmenopausal women, usually have a benign clinical course. Nevertheless, local recurrences and distant metastases have been described. By analyzing 511 cases retrieved from individual reports and cases series, we provide here the most comprehensive overview of UTROSCT cases available in the literature, supplemented by two new cases of UTROSCTs. Case 1 was an asymptomatic 31-year-old woman who underwent a laparoscopic resection of a presumed leiomyoma. Case 2 was a 58-year-old postmenopausal woman with abnormal vaginal bleeding who underwent an outpatient hysteroscopic biopsy of a suspicious endometrial area. In both cases, immunohistochemical positivity for Calretinin and Inhibin was noted, typical for a sex cord differentiation. In both cases, total laparoscopic hysterectomy with bilateral salpingo-oophorectomy was performed. In light of the available literature, no pathognomonic clinical or imaging finding can be attributed to UTROSCT. Patients usually present with abnormal uterine bleeding or pelvic discomfort, but 20% of them are asymptomatic. In most cases, a simple hysterectomy appears to be the appropriate treatment, but for women who wish to become pregnant, uterus-preserving approaches should be discussed after excluding risk factors. Age, tumor size, lymphovascular space invasion, nuclear atypia, and cervical involvement are not reliable prognostic factors in UTROSCT. The current research suggests that aggressive cases (with extrauterine spread or recurrence) can be identified based on a distinct genetic and immunohistochemical phenotype. For instance, UTROSCTs characterized by GREB1::NCOA1-3 fusions and PD-L1 molecule expression appear to be predisposed to more aggressive behaviors and recurrence, with GREB1::NCOA2 being the most common gene fusion in recurrent tumors. Hence, redefining the criteria for UTROSCTs may allow a better selection of women suitable for fertility-sparing treatments or requiring more aggressive treatments in the future.

J Clin Med 2023; 12:7131. [PMID: 38002745 PMCID: PMC10671931 DOI: 10.3390/jcm12227131] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/13/2023] [Revised: 10/18/2023] [Accepted: 11/14/2023] [Indexed: 11/26/2023] Open
Abstract
Uterine tumors resembling ovarian sex-cord tumors (UTROSCT) are thought to develop from pluripotent uterine mesenchymal cells or endometrial stromal cells with secondary sex-cord differentiation. The patient was a 73-year-old postmenopausal woman who had abnormal vaginal bleeding, and she underwent a laparoscopic hysterectomy with bilateral salpingo-oophorectomy. The diagnosis was a case of UTROSCT. A scoping review of the UTROSCT case report present in the literature has been conducted, and 63 articles were found, of which 45 were considered for the 66 clinical cases examined. At the time of diagnosis, six metastatic localizations were found in 59 patients undergoing demolitive surgery (10.2%). Recurrences were diagnosed in 13/59 (22%) patients with multiple locations. A molecular study was performed in 18/66 cases (27.3%) and genetic alterations were found in 10/18 (55.6%) patients. UTROSCTs are considered rare uterine tumors, typically with a favorable prognosis, and are generally considered to have a good prognosis. But, from the review done, they may already manifest themselves at advanced stages, with the possibility of recurrences even at a distance. It would, therefore, be important to be able to define the most aggressive forms and, perhaps, molecular investigation with sequencing could help identify patients most at risk.

Abstract
INTRODUCTION AND IMPORTANCE Cervical localization of uterine tumor resembling an ovarian sex cord tumor is very rare (UTROSCT) and this is the third case reported in the English literature. Given its rarity, the diagnosis is frequently challenging. Our aim was to discuss pathological characteristics and treatment choices of this rare disease happening in a rare location. CASE PRESENTATION Our case interested a 19-year-old female patient who presented with a lower abdominal pain and irregular menstrual cycles for a duration of two months. Gynecological examination revealed a cervical firm mass. The patient underwent a cervical lumpectomy. Microscopically, the tumor had nested and trabecular/cord patterns. Tumor cells had abundant cytoplasm, ovoid and spindle-shaped nuclei with fine chromatin. Mitoses were < 1/10 HPFs. A delicate vascular network of small capillaries was noted. Immunohistochemical staining showed that tumor cells were positive for Calretinin, AE1/AE3, Desmin, progesteron receptors, SMA and h-caldesmon. Pathological examination concluded to an UTROSCT. CLINICAL DISCUSSION UTROSC is a rare tumor with only two cases with cervical involvement reported so far. They have an indolent clinical history and thus require a more cautious and less invasive therapeutic decision. The diagnosis remains on the pathological examination. CONCLUSION This case is original by its location and the age of presentation. Careful follow-up is necessary searching for local recurrence or metastasis.

Abstract
BACKGROUND Endometrial stromal tumors originate from the endometrial stroma and account for < 2% of all uterine tumors. Uterine tumor resembling an ovarian sex cord tumor (UTROSCT) is a rare histological class of endometrial stromal and related tumors according to the latest World Health Organization classification of female genital tumors. Here, we report a case of UTROSCT in a 51-year-old woman.
CASE SUMMARY A 51-year-old woman had irregular menses for 6 mo. The patient visited a local hospital for vaginal bleeding. Pelvic computed tomography (CT) showed a mass in the pelvic cavity. Five days later, she came to our hospital for further diagnosis. The results of contrast-enhanced CT and pelvic ultrasound at our hospital suggested a malignant pelvic tumor. She then underwent total removal of the uterus with bilateral salpingectomy. Postoperative histological examination showed that the tumor cells had abundant cytoplasm, ovoid and spindle-shaped nuclei, fine chromatin, a high nucleoplasm ratio, and a lamellar distribution. The findings were consistent with UTROSCT, and the results of immunohistochemical analysis supported that diagnosis. The tumor was International Federation of Gynecology and Obstetrics stage IB. No adjuvant therapy was administered after radical surgery. The patient was followed up for 58 mo, and no recurrence was found.
CONCLUSION We report a case of UTROSCT with abnormal menstruation as a symptom, which is one of the most common symptoms. In patients with vaginal bleeding, ultrasonography can be used as a screening test because of its convenience, speed, and lack of radiation exposure. For patients with long-term tamoxifen use, routine monitoring of the endometrium is recommended. As UTROSCT may have low malignant potential, surgery remains the primary management strategy. Additionally, fertility preservation in patients of childbearing age is a vital consideration.

Abstract
ESR1 and GREB1 fusions have recently been described in uterine tumor resembling ovarian sex cord tumor (UTROSCT). Thus far, recurrences have been documented in a subset of those harboring GREB1 fusions, but not in those with ESR1 rearrangements. Here we describe the clinicopathologic features of 3 recurrent UTROSCTs with striking rhabdoid morphology (an unusual feature of these tumors overall) and ESR1-NCOA2 fusions. The patients were 32, 37, and 54 years at initial diagnosis and first recurrence occurred at 7, 9, and 32 years. The primary tumors (available in two cases) were centered in the myometrium and showed infiltrative borders. They predominantly grew in sheets and cords, but also had a pseudopapillary appearance. Cells were uniformly epithelioid with eccentric nuclei, prominent nucleoli, abundant eosinophilic globular/glassy (rhabdoid) cytoplasm, and infrequent mitoses (≤4/10 high-power fields [HPFs]). Recurrences were morphologically identical to the primary tumors, but demonstrated brisk mitotic activity (≥16/10 HPFs). The third tumor (with only recurrences available) had multiple patterns, including diffuse, corded, trabecular, and a focal retiform growth. Rhabdoid cells were conspicuous, but only comprised ~50% of the tumor, and mitoses numbered up to 2/10 HPFs. All tumors were strongly and diffusely positive for WT1, CAM5.2, ER, and PR, but negative for inhibin. Diffuse calretinin and desmin expression, as well as focal melan-A positivity, was noted in one tumor, but was negative in the others. In all 3 tumors, INI-1 and BRG-1 were retained, and ESR1-NCOA2 fusions were detected by targeted RNA sequencing. This study is the first to highlight an association between UTROSCTs with extensive rhabdoid differentiation, ESR1-NCOA2 fusions, and aggressive behavior. UTROSCTs are considered neoplasms of uncertain malignant potential, but have a benign course in most cases. Thus, it is important to be aware of these specific features and recommend long-term follow-up due to their propensity for late recurrences.

Abstract
Introduction Uterine tumors resembling ovarian sex cord tumor (UTROSCT) are a unique group of neoplasms with diverse morphology and immunophenotypic characteristics, coexpressing sex cord, epithelial, and smooth-muscle markers. To date, less than 100 cases have been reported and there is paucity of data concerning their clinical behavior. Materials and Methods All cases of uterine body tumors diagnosed over a period of two and a half years (2016-2018) were retrieved. Histopathological features were reviewed and extended panel of immunohistochemistry was performed to identify cases of UTROSCTs. Results Six cases of UTROSCTs were identified with a median age of 46.5 years. Four of them presented with menorrhagia, while two with postmenopausal bleeding including one with a history of carcinoma breast. Three of these cases were initially misdiagnosed as endometrial stromal sarcoma and adenocarcinomas. They all underwent hysterectomy with bilateral salpingo-oophorectomy. Conclusion It is considered a tumor with low malignant potential; however, one out of six cases (16.7%) in our study showed metastasis, within 1 year of diagnosis. It is important to recognize this entity as it mimics a wide range of both benign and malignant tumors. Molecular pathogenesis and exact management protocols remain elusive due to rarity,hence, multi-institutional studies are warranted.

Abstract
Uterine tumor resembling ovarian sex-cord tumor (UTROSCT) is a rare distinct cancer included in the current World Health Organization classification of endometrial stromal tumors. A battery of immunohistochemical markers are necessary for accurate diagnosis. Although few case reports and case series have been documented and therefore providing robust prognostic information several authors agree to consider UTROSCT as a low malignant potential tumour. In literature only five cases of conservative management were reported. We reported our experience and a review of conservative cases of literature. In this article we describe a series of 10 cases of UTROSCT and their clinical and pathologic feature. We report two cases of conservative surgical approach obtaining a successfully pregnancies. All of the patients are still alive. In conclusion, fertility sparing surgery should be offered to patients who wish preserve their fertility however radical surgery must be considerate after childbirth. Close follow-up is required for all patients due to the lack of prognostic biomarkers and long follow up is needed to evaluate safety of conservative surgery.

Abstract
Uterine tumor resembling ovarian sex-cord tumor (UTROSCT) is a rare and distinctive neoplasm of unclear histogenesis, and uncertain malignant potential. These neoplasms morphologically resemble sex-cord stromal tumors of the ovary, and possess a polyphenotypic immunophenotype. Their molecular pathogenesis has yet to be elucidated; notably, however, tumors lack alterations found in other uterine tumors bearing sex-cord-like differentiation, such as endometrial stromal sarcoma. Following identification of an index patient with an ESR1-NCOA3 fusion gene by RNA-sequencing, we undertook a retrospective review for additional cases of UTROSCT. We identified a total of 4 patients, with an average age of 53 years (range, 38 to 68 y). RNA-sequencing was performed in all cases, revealing an ESR1-NCOA3 fusion in 2 cases and one case each with related ESR1-NCOA2 and GREB1-NCOA2 fusions. Each of the tumors showed histologic and an immunophenotype features within the previously reported spectrum of UTROSCT; interestingly, one case contained prominent spindle cell fascicles and another was largely comprised of sheets of small round cells. Our results demonstrate UTROSCT are defined by recurrent fusions involving NCOA2 or NCOA3, a finding that is directly amenable to diagnostic evaluation. This study confirms UTROSCT is molecularly distinct from endometrial stromal sarcoma, and raises intriguing new questions into the pathogenesis of these neoplasms and possible relationship with other NCOA fusion-positive uterine tumors.

Abstract
Uterine tumors resembling ovarian sex-cord tumors (UTROSCTs) are rare uterine neoplasms of uncertain etiology that resemble the sex cord tumors of the ovary and display a combined sex cord, epithelial, and smooth muscle immunophenotype. Most tumors are associated with a benign clinical course. We report the first cytological description of uterine UTROSCTs in liquid-based cervical cytology (LBC). A menopausal woman was discovered to have a uterine intraluminal polypoid mass protruding through the vagina. A Pap test was performed, and the LBC preparation showed isolated tumor cells with scant cytoplasm and slightly irregular, ovoid nuclei with fine chromatin and small nucleoli. Final histological evaluation identified a UTROSCT. This diagnostic possibility, albeit rare, should be included in the differential diagnosis when isolated malignant-appearing adenocarcinomatous cells are seen in women in the above scenario. As these features are not specific, they may result in misinterpretation with tumors that are more common and aggressive.

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
Mesenchymal tumors of the uterus comprise a heterogeneous group of neoplasms of varied biologic potential. In addition to being host to several anatomically unique entities, the uterus may contain mesenchymal neoplasms typically found elsewhere in the body. Although smooth muscle neoplasms are common, other mesenchymal neoplasms in this location are relatively rare. Many of these neoplasms exhibit morphologic overlap. In addition to a careful histomorphologic review, definitive classification frequently depends on the judicious application of ancillary immunohistochemical and molecular testing. The intent of this review is to offer a basic approach to the classification of primary uterine mesenchymal neoplasms.

Abstract
RATIONALE Massive ascites as the first sign of ovarian juvenile granulosa cell tumor (JGCT) in an adolescent is an extremely rare, and its clinical features and treatment methods have not been well described. PATIENT CONCERNS The clinical characteristics, diagnosis, and treatment methods in a 19-year-old girl who presented with massive abdominal distention and ascites was retrospectively reviewed. Abdominopelvic ultrasonography showed a large amount of ascites. The nature of ascites was exudate. All tumor markers were normal, but ascites and serum tumor CA125 levels were significantly increased. Abdominal CT showed left attachment area teratoma and right attachment area capsule solid change. DIAGNOSES Histological and immunohistochemical results were compatible with JGCT. Based on the FIGO classification, the patient with only malignant ascites was categorized into stage IC. INTERVENTIONS The patient underwent mass resection with salpingoophorectomy. Following the operation, she received 6 courses of adjuvant chemotherapy with Nedaplatin and Paclitaxel liposome. OUTCOMES The patient was followed up postoperatively for 6 months to date without recurrence. LESSONS We should be highly vigilant the JGCT with massive ascites as the first clinical manifestation.

Abstract
Sex cord-like differentiation has been well documented in endometrial stromal tumors. On the basis of the extent of sex cord differentiation, uterine stromal tumors with this kind of differentiation have been classified into 2 subgroups of endometrial stromal tumor with sex cord-like elements and uterine tumors resembling ovarian sex cord tumor. When extensive, this differentiation has been accompanied with indolent clinical behavior and rather good prognosis in most cases. Sex cord differentiation has been rarely observed in uterine mullerian adenosarcoma. Only 3 cases of such occurrence have been reported in the English literature. Herein, we report a case of uterine mullerian adenosarcoma extensively overgrown by uterine tumor resembling ovarian sex cord tumor in a young woman. The presence of an ovarian sex cord tumor component has been confirmed by immunohistochemistry. To the best of our knowledge, this is the second report of such a case in the English literature.

Abstract
Uterine Tumour Resembling Ovarian Sex-Cord Tumours (UTROSCTs) are an extremely rare type of uterine body tumours arising from the endometrial stroma. Epidemiology, aetiology, pathogenesis, management and natural history of UTROSCTs are still a question of debate, as there is little available data in the literature. Although rare, the possibility of UTROSCTs should be kept in mind, when a patient presents with abnormal bleeding and an enlarged uterus. UTROSCTs appear dirty white/cream-coloured, gelatinous, well-circumscribed mass with smooth surface on macroscopic examination. We present a rare case of endometrial stromal tumour with sex-cord-like differentiation which was successfully treated by hysterectomy with bilateral salpingo-oophorectomy. The clinical manifestations, pathologic characteristics, diagnosis and management of these tumours are reviewed here.

Abstract
The aim of this study was to perform an immunohistochemical comparison of uterine tumour resembling ovarian sex cord-stromal tumour (UTROSCT) and other uterine lesions with sex cord-like (SCL) differentiation. Six UTROSCTs and 10 potential histological mimics with focal SCL elements were examined, the latter comprising three endometrial stromal nodules, three low-grade endometrial stromal sarcomas, three Müllerian adenosarcomas, and one case of adenomyosis. All cases were stained immunohistochemically for SF1, FOXL2, calretinin and inhibin, and for the less specific markers smooth muscle actin, desmin, CD10, CD56, CD99, cytokeratin, oestrogen receptor and progesterone receptor. Three, four, six and three UTROSCT expressed SF1, FOXL2, calretinin and inhibin, respectively. However, calretinin staining was focal (≤50% cells positive) in five of the cases. Three potential histological mimics demonstrated calretinin, FOXL2 and/or inhibin staining but none was SF1 positive. Most cases in both groups expressed the less specific immunomarkers. SF1 and FOXL2 immunoreactivity in UTROSCT further supports the concept that these tumours demonstrate genuine sex cord-stromal differentiation. While calretinin was the most sensitive UTROSCT marker, staining was usually focal and expression was also seen in two of 10 potential histological mimics. SF1 staining was 100% specific for UTROSCT in this series but this finding should be confirmed in larger studies.

Abstract
Uterine tumors resembling ovarian sex cord tumors (UTROSCTs) are rare uterine neoplasms characterized by pure or predominant epithelial-like patterns that share morphologic, immunohistochemical, and ultrastructural features with ovarian sex cord tumors. FOXL2 immunoexpression has recently been found in sex cord stromal tumors of the ovary, including granulosa cell tumors, Sertoli-Leydig cell tumors, thecomas, and fibromas, but mutations have been identified mostly in adult granulosa cell tumors. In this study, we investigated FOXL2 mutation status and protein expression in UTROSCTs. Mutational analysis using a TaqMan real-time polymerase chain reaction-based allelic discrimination assay was performed on formalin-fixed, paraffin-embedded tissue from 15 UTROSCTs. FOXL2 mutation was absent in all tumors. FOXL2 immunoexpression was tested in all 15 tumors. Intensity of staining was scored as weak, moderate, or strong. Percentage of tumor cells with nuclear staining was recorded as follows: 0 (negative); 1+ (1% to 25%); 2+ (26% to 50%); 3+ (51% to 75%); and 4+ (76% to 100%). Nuclear expression of FOXL2 was present in 6 of 15 (40%) UTROSCTs. One tumor demonstrated strong 4+ staining. Moderate expression was seen in 3 cases, including 2 and 1 showing 2+ and 1+ staining, respectively. Weak expression was observed in 2 tumors demonstrating 3+ and 1+ staining. Although UTROSCTs show overlapping morphologic, immunohistochemical, and ultrastructural features with sex cord stromal tumors of the ovary, they do not harbor FOXL2 mutation despite focal immunoreactivity in a subset of these tumors.

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
The Wilms tumor gene 1 (WT1) has been reported in normal tissues and many neoplasms of the female genital tract. This review discusses WT1 expression in the female genital tract and its potential utility in the differential diagnosis of neoplasms that occur at this location. WT1 is of value in the differential diagnosis of synchronous serous carcinomas arising in the ovary/fallopian tube/peritoneum and endometrium, as strong WT1 positivity in both tumors points toward an extrauterine origin. In addition, WT1 can be used to distinguish sex cord stromal tumors (WT1 positive) from endometrioid carcinomas (OECs). WT1 expression is not helpful in the differential diagnosis of ovarian serous carcinomas (OSCs) and transitional carcinomas, as both are typically positive and has limited value in the distinction of serous tumors arising in the ovary/fallopian tube/peritoneum from mesotheliomas. WT1 is also not helpful to differentiate small cell carcinoma of hypercalcemic type from juvenile granulosa cell tumor, a common diagnostic problem. Intra-abdominal desmoplastic round cell tumor reacts to WT1 (C-terminal) in contrast to all other tumors discussed which helps to separate this rare tumor from most other small round cell tumors that may involve, primarily or secondarily, the ovary with the exception of small cell carcinoma of hypercalcemic type that typically reacts with the N-terminal of WT1.

Abstract
Uterine tumors resembling ovarian sex cord-stromal tumors (UTROSCTs) are very rare. In this article, we present 3 cases that manifest classical histomorphological features alongside diverse immunohistochemical findings. As a distinctive finding, one of the patients had UTROSCT in the uterus and an ovarian sex cord tumor, called granulosa cell tumor, in the left ovary, simultaneously. Problems in diagnosing such pathologic condition generally arise because of the variable histologic picture of UTROSCT and may cause problems for general and other nongynecologic surgical pathologists. Immunohistochemically, these tumors express different markers that indicate their polyphenotypic origins.

Abstract
Uterine tumors resembling ovarian sex cord tumors (UTROSCT) are tumors of unclear histogenesis. The authors analyzed the ultrastructural features of 13 UTROSCT and correlated the findings with their immunohistochemical profile. Features included cells with frequent organoid, nested or cord-like arrangement (8), lumen formation (2; one of which showed surface microvilli), nuclei with irregular indentations (8), intermediate filaments (13), prominent paranuclear aggregates (5), cell junctions (9), desmosome-like junctions (2), tonofilaments (2), basal lamina (1), and cytoplasmic lipid droplets (7; prominent in 3). No dense bodies, subplasmalemmal densities or pinocytotic vesicles were seen. Ultrastructural epithelial differentiation was present in 2 tumors (positive for keratin or epithelial membrane antigen). Prominent lipid droplets correlated with sex cord markers positivity in 2 tumors. Ultrastructural features of smooth muscle differentiation were lacking and abundant paranuclear filaments did not correlate with myoid markers. UTROSCT are polyphenotypic neoplasms ultrastructurally with focal epithelial and variable sex cord-like differentiation. These findings suggest that UTROSCT may result from divergent differentiation in endometrial stromal tumors or represent a distinct group of uterine tumors with sex cord-like differentiation that are closer in histogenesis to ovarian sex cord stromal tumors.

Abstract
Endometrial/ioid stromal tumors comprise a spectrum of mesenchymal neoplasms, ranging from benign to low-grade malignancy to undifferentiated sarcomas, which occur predominantly in the uterus but may rarely originate at extrauterine sites, most commonly in the ovary. These tumors and their morphologic variants are important to recognize as they often cause diagnostic difficulties. This review focuses on the diagnostic criteria and differential diagnosis, including the role of immunohistochemistry.

Abstract
The utility of calretinin was first described in the diagnosis of mesothelioma. In the female genital tract, calretinin was initially reported in Wolffian remnants and related lesions and later used in the diagnosis of sex cord stromal tumors of the ovary, endometrial stromal tumors with sex cord-like differentiation, and uterine tumors resembling sex cord tumors of the ovary. This review discusses calretinin expression in normal tissues of the female genital tract and highlights its potential utility in the diagnosis of these subsets of neoplasms with emphasis to tumors that may constitute a problem in their differential diagnosis. In particular, the limited utility of calretinin in the diagnosis of sex cord stromal tumors of the ovary, in the differential diagnosis between mesothelioma and serous tumors involving the ovary and/or peritoneum, and in the differential diagnosis between Wolffian lesions and endometrial carcinoma are addressed.

Abstract
Most endometrial stromal sarcomas (ESSs) have a characteristic histologic appearance and the diagnosis is easily made based on the typical growth pattern, vascular pattern, and cell type. However, there are several variants, which may result in problems in diagnosis and consideration of other neoplasms. We describe 3 examples of a hitherto not well-described phenomenon in uterine ESS, namely the formation of papillae or pseudopapillae. The patients were aged 37, 42, and 52. In 2 cases, the neoplasms were typical ESSs apart from the presence of pseudopapillae; in 1 case the pseudopapillae were present throughout the neoplasm and in the other this was a focal finding involving 10% of the tumor. In the third case, there was a true papillary component involving sex cord-like elements within an ESS and a prominent papillary architecture in the metastatic tumor which developed 7 years later resulted in initial misdiagnosis as a serous adenocarcinoma. This report emphasizes the potential for ESSs to form pseudopapillae or true papillae, which may involve areas of usual ESS or sex cord-like elements. The formation of papillae or pseudopapillae may result in diagnostic difficulty and confusion with other neoplasms, especially if the phenomenon is widespread.

We report two cases of "uterine leiomyoma with tubules" as a new pathological entity. Since these are biphasic neoplasms (composed by epithelial and mesenchimal elements), the differential diagnosis is between mixed mullerian tumors and uterine tumors resembling ovarian sex cord tumors (UTROSCTs). In the differential diagnosis, the mixed mullerian tumors are easily excluded because of histological and immunohistochemical features. UTROSCTs are similar to the lesions we reported, and the differential diagnosis requires positivity for some immunohistochemical markers as inhibin, CD99, calretinin, Melan-A. Our conclusions are that to perform a diagnosis of UTROSCT at least two immunohistochemical marker have to be expressed; in the present case they didn't, so we call the lesion "leiomyoma with tubules".

Abstract
Uterine tumors resembling ovarian sex cord tumors (UTROSCT) are rare entities. They were described by Clement and Scully in 1976 who classified them into groups I and II. Group I comprises typical endometrial stromal neoplasms with focal areas resembling ovarian sex cord elements and group II are predominantly or completely composed of ovarian sex cord-like elements. We report a case of UTROSCT type II with cytogenetic analysis. The tumor occurred in a 76-year-old woman who presented with vaginal bleeding. The tumor was lobulated, firm, yellow and histologically composed of sex cord-like elements. Tumor cells expressed vimentin, CD10, CD99 and alpha-actin. Cytogenetic analysis in a previously reported case detected translocation t(4;18)(q21.1;q21.3) in the majority of cells. Bcl-2 and MALT1 genes are located at or near the translocation breakpoints, and the aim of this study was to determine whether these genes were involved in chromosomal translocation or tumorigenesis. We did not find IgH translocation or the most common MALT translocations. Bcl-2 was also not involved in this oncogenesis.

Abstract
As with biopsies from other sites in the female genital tract, immunohistochemistry is now being increasingly used in cervical pathology as an aid to diagnosis. In this review, I discuss applications of immunohistochemistry in diagnostic cervical pathology with a particular focus on recent developments. It is emphasised that immunohistochemistry is to be used as an adjunct to routine morphological examination and that no marker is totally specific or sensitive for a given lesion. Although much of this review focuses on glandular lesions, the value of markers, such as MIB1 and p16, in the assessment of pre-invasive cervical squamous lesions is discussed. In the broad field of cervical glandular lesions, topics covered include: the value of markers such as MIB1, p16 and bcl-2 in distinguishing adenocarcinoma in situ and glandular dysplasia from benign mimics; markers of mesonephric lesions, including CD10; markers of value in the diagnosis of minimal deviation adenocarcinoma, such as HIK1083; markers of value in distinguishing metastatic cervical adenocarcinoma in the ovary from primary ovarian endometrioid or mucinous adenocarcinoma. Rarely ectopic prostatic tissue occurs in the cervix, which can be confirmed by positive staining with prostatic markers. A panel of markers, comprising oestrogen receptor, vimentin, monoclonal carcinoembryonic antigen and p16, is of value in distinguishing between a cervical adenocarcinoma and an endometrial adenocarcinoma of endometrioid type. Markers of use in the diagnosis of cervical neuroendocrine neoplasms, including small cell and large cell neuroendocrine carcinoma, are discussed. It is stressed that small cell neuroendocrine carcinomas may be negative with most of the commonly used neuroendocrine markers and this does not preclude the diagnosis. p63, a useful marker of squamous neoplasms within the cervix, is of value in distinguishing small cell neuroendocrine carcinoma (p63 negative) from small cell squamous carcinoma (p63 positive) and in confirming that a poorly differentiated carcinoma is squamous in type.

Abstract
AIMS To describe the clinicopathological and immunohistochemical findings in four cases of uterine tumour resembling ovarian sex cord tumour (UTROSCT). METHODS Four UTROSCTs were stained with a wide range of antibodies, including epithelial (AE1/3, epithelial membrane antigen), myoid (desmin, alpha smooth muscle actin, h-caldesmon), sex cord (alpha inhibin, calretinin, melan A, CD99) and neuroendocrine (chromogranin, CD56) markers as well as hormone receptors (oestrogen receptor, progesterone receptor, androgen receptor), vimentin, CD10, WT1 and HMB45. RESULTS The tumours ranged from 0.8 to 19.5 cm. Three were relatively well circumscribed intramural myometrial lesions; the other was a pedunculated mass attached to the uterine serosa. The tumours were variably composed of solid, corded, trabecular, nested, glandular and retiform arrangements of tumour cells. In three cases, cells with eccentric nuclei and abundant eosinophilic cytoplasm, resulting in a rhabdoid appearance, were a prominent feature. Three cases were diffusely positive with AE1/3 and all with epithelial membrane antigen. Positivity with myoid markers was common with 3, 4 and 1 case respectively staining with desmin, alpha smooth muscle actin and h-caldesmon; 2, 4, 1 and 2 cases respectively were positive with alpha inhibin, calretinin, melan A and CD99. All were chromogranin negative and exhibited diffuse strong staining with CD56. All were diffusely positive with oestrogen receptor, progesterone receptor, vimentin and WT1. Three cases were androgen receptor positive and all were CD10 and HMB45 negative. CONCLUSIONS UTROSCT exhibits a polyphenotypic immunophenotype with coexpression of markers of epithelial, myoid and sex cord lineage as well as hormone receptors.

Abstract
In this study, we present the clinicopathologic features and immunophenotypic characteristics of five cases of uterine tumors resembling ovarian sex cord tumors and three cases of endometrial stromal tumors with sex cord-like elements, with emphasis on immunohistochemical markers of sex cord differentiation. The mean patient age was 42 years (range 19-69 years), and vaginal bleeding was the most common clinical presentation. The tumors were usually polypoid masses arising in the uterine fundus, with a mean tumor size of 6.7 cm. Sex cord patterns in uterine tumors resembling ovarian sex cord tumors, including anastomosing cords, trabeculae, small nests, tubules, and in one case, a striking retiform architecture with Leydig-like cells, comprised from 70 to 100% of the tumor volume. All uterine tumors resembling ovarian sex cord tumors were positive for two or more markers of sex cord differentiation; all five cases showed strong immunoreactivity for calretinin, with coexpression of CD99 (four cases), Melan-A (two cases), and inhibin (two cases). Endometrial stromal tumors with sex cord-like elements were less frequently positive for markers of sex cord differentiation, with each case positive for one marker (calretinin, two cases; CD99, one case). In addition, all eight cases were frequently positive for cytokeratin, CD10, vimentin, estrogen receptor, and progesterone receptor; desmin immunoreactivity, when present, was limited to minor foci of smooth muscle. Overall, the morphologic and immunohistochemical findings in uterine tumors resembling ovarian sex cord tumors strongly support that these unusual uterine tumors are polyphenotypic neoplasms with true sex cord differentiation.

Abstract
In the female genital tract, CD10 was initially found to be expressed in endometrial stromal tumors of the uterus as well as in mesonephric remnants and related lesions and was thought to be helpful in distinguishing these tumors from their mimics. However, new studies have shown CD10 to be expressed in a wide range of tumors of the female genital tract, making this antibody of limited diagnostic value. This review discusses diagnostic applications of CD10 in the female genital tract, with emphasis on CD10 use in mesenchymal tumors of the uterus and in the differential diagnosis of mesonephric versus non-mesonephric carcinomas, where CD10 positivity alone may be misleading in the final classification of a tumor. CD10 may be useful in establishing the diagnosis of endometriosis (with the exception of the cervix), distinguishing metastatic renal clear cell carcinoma from a primary ovarian clear cell carcinoma, and distinguishing mesonephric hyperplasia from other benign glandular proliferations of the cervix.

Abstract
In recent years there have been a plethora of publications regarding the value of immunohistochemical studies in diagnosis in gynecological pathology. In many instances, papers are published initially that suggest that a certain antibody or panel of antibodies is of value in the diagnosis of a particular neoplasm and in the distinction of this from mimics. However, this is usually quickly followed by other studies that somewhat contradict these findings. The aim of this review is to present a critical appraisal of the value of immunohistochemical studies in the diagnosis of uterine neoplasms with emphasis on the recent literature. It is stressed that immunohistochemistry is necessary in relatively few cases and a knowledge of the potential immunoreactivity of utilized antibodies is required. With regard to endometrial carcinoma, topics discussed in this review include antibodies of value in the distinction between type 1 and type 2 carcinoma, in the characterization of focal serous proliferations in endometrial polyps and non-polypoid endometrium, in the sometimes problematic distinction between an endometrial and an endocervical adenocarcinoma, and in the distinction between a uterine and ovarian serous carcinoma. The value of CD10 as a proposed marker of mesonephric adenocarcinoma is also discussed. With regard to uterine mesenchymal neoplasms, a critical appraisal of the value of relatively new antibodies, including CD10 and h-caldesmon, in distinguishing between a smooth muscle and an endometrial stromal neoplasm is discussed as is the immunophenotype of two rare uterine mesenchymal neoplasms, uterine tumor resembling ovarian sex cord tumor (UTROSCT) and perivascular epithelioid cell tumor (PEComa).
