Abstract
Renal cell carcinoma is a term that represents multiple different disease processes, each driven by different genetic alterations, with distinct histology, and biological potential which necessitates divergent management strategies. This review discusses the genetic alterations seen in several forms of hereditary kidney cancer and how that knowledge can dictate when and how to intervene with a focus on the surgical management of these tumors.

Abstract
Although diagnosis of high-grade uterine mesenchymal tumors (UMTs) exhibiting classic morphologic features is straightforward, diagnosis is more challenging in tumors in which prototypical features are poorly developed, focal, and/or coexist with features seen in other neoplasms. Here, we sought to define the repertoire of somatic genetic alterations in diagnostically challenging UMTs with myomelanocytic differentiation, including some reported as perivascular epithelioid cell tumors (PEComas). In 17 samples from 15 women, the tumors were histologically heterogenous. Immunohistochemical expression of at least 1 melanocytic marker (HMB45, Melan-A, or MiTF) was identified in all tumors, and of myogenic markers (desmin or smooth muscle actin) in most tumors. Targeted massively parallel sequencing revealed several genetic alterations, most commonly in TP53 (41% mutation, 12% deletion), TSC2 (29% mutation, 6% deletion), RB1 (18% deletion), ATRX (24% mutation), MED12 (12% mutation), BRCA2 (12% deletion), CDKN2A (6% deletion) as well as FGFR3, NTRK1, and ERBB3 amplification (each 6%). Gene rearrangements (JAZF1-SUZ12; DNAJB6-PLAG1; and SFPQ-TFE3) were identified in 3 tumors. Integrating histopathologic, immunohistochemical, and genetic findings, tumors from 4 patients were consistent with malignant PEComa (1 TFE3-rearranged); 6 were classified as leiomyosarcomas; 3 showed overlapping features of PEComa and other sarcoma types (leiomyosarcoma or low-grade endometrial stromal sarcoma); and 2 were classified as sarcoma, not otherwise specified. Our findings suggest that diagnostically challenging UMTs with myomelanocytic differentiation represent a heterogenous group of neoplasms which harbor a diverse repertoire of somatic genetic alterations; these genetic alterations can aid classification.

Abstract
Carcinosarcoma (CS) of the uterus or ovary is a rare, aggressive and biphasic neoplasm composed of carcinoma and sarcoma elements. Previous genomic studies have identified the driver genes and genomic properties associated with CS. However, there is still no molecular subtyping scheme with clinical relevance for this disease. Here, we sequence 109 CS samples, focusing on 596 genes. We identify four molecular subtypes that resemble those observed in endometrial carcinoma: POLE-mutated, microsatellite instability, copy number high, and copy number low subtypes. These molecular subtypes are linked with DNA repair deficiencies, potential therapeutic strategies, and multiple clinicopathological features, including patient outcomes. Multi-regional comparative sequencing reveals genomic alteration-independent CS cell differentiation. Transcriptome and DNA methylome analyses confirm epithelial-mesenchymal transition as a mechanism of sarcoma differentiation. The current study thus provides therapeutic possibilities for CS as well as clues to understanding the molecular histogenic mechanism of its development.

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
OBJECTIVES To determine how human papillomavirus (HPV) positivity of atypical glandular cells (AGCs) affects the predictive values for the presence of high-grade cervical lesions. DESIGN Population-based cohort study. SETTING Stockholm-Gotland region, Sweden. PARTICIPANTS Between 17 February 2014 and 30 June 2016, there were 562 women with AGC detected in a cervical sample. Registry linkages up to 30 June 2016 identified 392 women with an associated HPV test and a histopathological follow-up. MAIN OUTCOME MEASURE Presence of a high-grade cervical lesion in the cervical biopsy taken after the AGC smear, in relation to the HPV status of the AGC-containing index smear. RESULTS The proportion of HPV-positive AGC was 56% (n=222). In this group, there were six cases of invasive cervical adenocarcinoma, 33 cases of cervical adenocarcinoma in situ and 93 cases of high-grade squamous intraepithelial lesion (HSIL), giving a positive predictive value (PPV) for a cervical high-grade lesion of 60% (132/222). Among the 170 women with HPV-negative AGC, there was one invasive cervical squamous cell cancer and four HSIL, giving an PPV for a cervical high-grade lesion of 2.9% (5/170). This group also contained five endometrial cancers and one breast cancer. CONCLUSIONS HPV triaging of AGC will greatly increase the predictive ability for identifying cervical high-grade lesions (OR: 48.4 (95% CI 19.1 to122.6)) and the high sensitivity (96%; 132/137 women) implies safety of primary HPV screening strategies, with regard to this subset of patients. The measurable risk for endometrial cancer among women with HPV-negative AGC (2.9%) suggests that research on screening for endometrial cancer is needed.

Abstract
PURPOSE OF INVESTIGATION This study aimed to estimate the effectiveness of hysteroscopic myomectomy for symptomatic submucous uterine fibroids and to identify prognostic factors for persistent or recurrent symptoms. MATERIALS AND METHODS A total of 237 patients who underwent hysteroscopic myomectomy were divided into three groups according to the classification of the European Society for Gynaecological Endoscopy: Type 0 (n=116), Type I (n=97), and Type II (n=24). Medical records and videotape records of all patients were retrospectively reviewed. RESULTS Improvement of symptoms was achieved in 100% of Types 0 and I, and 66.7% of Type II. The five-year cumulative symptom-free rates after hysteroscopic myomectomy were 96.7% ± 1.9%, 87.8% 6.7%, and 44.5% ± 12.7% in Types 0, I, and II, respectively. The mean symptom-free periods were 46.2 ± 2.6, 47.7 ± 2.7, and 24.7 ± 6.3 months in Types 0, I, and II, respectively. Logistic regression analysis showed that co-existence of other myomas and Type II were independent prognostic factors for recurrence of symptoms. CONCLUSION Type I fibroids are a good indication for hysteroscopic myomectomy. In Type II, some patients feel that their symptoms improve, but this curative effect could be temporary.

Abstract
We report 3 cases of a distinctive uterine leiomyoma containing numerous thick-walled vascular channels, which we term angioleiomyoma. The leiomyomas occurred in women aged 33, 44, and 49 and ranged from 1.5 to 6.0 cm. They were composed of bland, spindle-shaped cells with numerous evenly distributed, arteriole-like vessels with thick muscular walls throughout. The spindle cells often swirled around the vessels. In 1 case, fibrin was present within vessel walls. The spindle cells were positive with smooth-muscle markers and negative with HMB45. We believe angioleiomyoma should be recognized as a distinct entity and included in the World Health Organization classification of tumors of the female genital tract as a benign leiomyoma variant, similar to cellular and atypical leiomyoma. Uterine angioleiomyoma has a close morphological resemblance to the similarly named skin tumor. We review uterine smooth-muscle and other mesenchymal neoplasms in which prominent vascular channels are a feature.

Abstract
The oncogenic phosphatidylinositol 3-kinase-AKT-mammlian target of rapamycin pathway (PI3K-AKT-mTOR) pathway is known to be activated in uterine smooth muscle tumors, and Stathmin 1 (STMN1) expression has been identified as a marker of PI3K-AKT-mTOR pathway activation. We hypothesized that STMN1 may have some diagnostic utility and explored how well STMN1 expression correlated with histologic classifications of uterine smooth muscle tumors into benign and malignant groupings. 84 smooth muscle tumors were assessed for STMN1 expression by immunohistochemistry. These included spindle cell leiomyosarcoma (n=32), conventional spindle cell leiomyomas (n=30), atypical (symplastic) leiomyoma (n=5), cellular leiomyoma (n=7), smooth muscle tumor of uncertain malignant potential (n=4), mitotically active leiomyomas (n=2), benign metastasizing leiomyoma (n=3), and cotyledonoid dissecting leiomyoma (n=1). All spindle cell leiomyosarcomas were positive (32/32 positive; 100%) as compared with conventional leiomyomata (11/30; 37%) (P<0.0001). The average immunohistochemical score (0-12+, reflective of intensity and extent) for leiomyosarcomas was 8.7 (±1.43) whereas the conventional leiomyomata average score was 1.6 (±1.07) (P<0.0001). This difference in scores was reflected in the patterns of expression: leiomyosarcomas were predominantly strongly and diffusely positive whereas leiomyomata were predominantly weakly, albeit diffusely positive when expression was present. The sensitivity of STMN1 expression for leiomyosarcomas was 100%. However, the specificity was found to be only 55% (CI=43-68%). The negative and positive predictive values for leiomyosarcomas were 100% and 52% respectively. The odds ratio (OR) for any STMN1 expression in predicting a spindle cell leiomyosarcoma diagnosis from this dataset was highly significant (OR=144, P=0.0006). Thirteen non-smooth muscle tumors that involved the uterus all showed at least focal STMN1 immunoreactivity. In summary, STMN1 is a highly sensitive marker for leiomyosarcoma but is suboptimally specific for diagnostic purposes. The 100% negative predictive value for leiomyosarcoma may offer some diagnostic utility in a small sample, since the absence of STMN1 immunoreactivity in a putative leiomyosarcoma is a strong argument against this diagnostic possibility.

Abstract
Leiomyoma is the most frequent benign monoclonal tumor (cells behave identically in culture) of the female reproductive system. It affected almost 50% of childbearing age women, deteriorating the quality of life and may cause infertility. The unique features of this pathology is the absence of detailed understanding of pathogenic mechanisms and continuous morbidity among any age groups. Despite the huge amount of articles and studies related to leiomyoma, review pretend to depict herein actual and non-trivial information. This review assemble a versatile description of medical and biological aspects of leiomyomas. Explanation of genetic, molecular, pathophysiological mechanisms of uterine fibroid growing predetermine marked clinical symptoms of pathology. Mentioned model systems show multivariation of leiomyomas in human and animals. Review gives an opportunity analyze separate facets and collect it in one deep understanding of leiomyomas.

Abstract
PURPOSE The aim of this study was to assess the diagnostic value of sonographic pattern recognition by experts, a standardized morphological scoring system, the risk malignancy index (RMI) and CA 125 assay for the preoperative assessment of ovarian lesions in premenopausal patients. MATERIAL AND METHODS Diagnostic work-up of 1320 patients who underwent surgical exploration due to an adnexal mass at a tertiary referral center were included. We assessed the discriminative value of pattern recognition, a sonographic morphological scoring system, RMI and CA 125 by calculating sensitivity, specificity, positive predictive value (PPV), negative predictive value (NPV) and Cohen's kappa for each diagnostic approach while using histopathology as the reference standard. RESULTS Pattern recognition showed the highest discriminative power with an observed kappa of 0.53. Sensitivity and specificity yielded 0.76 and 0.97 respectively. Combining pattern recognition with CA 125 serum measurement in the context of a triage system diminished the diagnostic value (kappa: 0.24; sensitivity: 0.29 specificity: 0.97). For the RMI we observed a sensitivity of 0.54 and a specificity of 0.96 and estimated kappa value yielded 0.37. Omitting the CA 125 assay and using a morphological sonographic assessment system increased the kappa value to 0.45 with sensitivity and specificity observed at 0.61 and 0.97 respectively. CONCLUSION Expert pattern recognition was found to be the method with the highest discriminative power in assessing an adnexal mass during premenopause. Additional assessment of serum CA 125 diminished the diagnostic accuracy. Standardized morphological sonographic assessment resulted in a moderate diagnostic accuracy. Supplementing the morphological sonographic assessment with CA 125 by using the RMI algorithm did not improve the diagnostic value.

Abstract
OBJECTIVE To evacuate whether short-tandem-repeat (STR) DNA genotyping is effective for diagnostic measure to precisely classify hydatidiform moles. METHODS 150 cases were selected based on histologic features that were previously diagnosed or suspected molar pregnancy. All sections were stained with hematoxylin as a quality control method, and guided the microscopic dissection. DNA was extracted from dissected chorionic villi and paired maternal endometrial FFPE tissue sections. Then, STR DNA genotyping was performed by AmpFlSTR(®) Sinofiler(TM) PCR Amplification system (Applied Biosystems, Inc). Data collection and analysis were carried out using GeneMapper(®) ID-X version 1.2 (Applied Biosystems, Inc). RESULTS DNA genotyping was informative in all cases, leading to identification of 129 cases with abnormal genotype, including 95 complete and 34 partial moles, except 4 cases failed in PCR. Among 95 complete moles, 92 cases were monospermic and three were dispermic. Among 34 partial moles, 32 were dispermic and 2 were monospermic. The remaining 17 cases were balanced biallelic gestations. CONCLUSION STR DNA genotyping is effective for diagnostic measure to precisely classify hydatidiform moles. And in the absence of laser capture microdissection (LCM), hematoxylin staining plus manual dissection under microscopic guided is a more economic and practical method.

Abstract
Uterine sarcomas account for less than 10% of all uterine neoplasms (Tropé et al., 2012). The most common include uterine leiomyosarcoma and the endometrial stromal neoplasms. The diagnosis requires pathologic review of the uterus in order to characterize extent of myometrial invasion. However, molecular diagnosis has aided the classification of endometrial stromal neoplasms, especially in helping to discriminate between endometrial stromal and undifferentiated endometrial sarcoma. The prognosis of these tumors following surgery varies, with endometrial stromal sarcoma associated with a better prognosis compared to leiomyosarcoma or undifferentiated endometrial sarcoma. For aggressive sarcomas, there is interest in adjuvant treatment, which has focused on the evaluation of systemic agents. However, the rarity of these tumors makes the conduct of prospective trials difficult and no consensus adjuvant regimen has emerged. In the absence of Level I data, the use of chemotherapy is based on institutional preferences. Ongoing clinical trials will help inform the standard treatment approach for these tumors, and we encourage patients with uterine sarcoma to participate in well-designed clinical trials.

Abstract
Adnexal tumors of the skin are epithelial skin tumors with differentiation towards the adnexal epithelial structures of the skin, namely, hair follicle, sebaceous gland, apocrine gland, and eccrine gland. Adnexal tumors include hamartomas, benign and malignant neoplasms, and hyperplasias. The specific diagnosis of adnexal tumors is important because some lesions such as sebaceous neoplasms, cylindromas, or fibrofolliculomas are herald lesions of hereditary tumor syndromes (e.g., Muir-Torre syndrome, familial cylindromatosis, Birt-Hogg-Dubé syndrome). In this article, the classification of adnexal tumors of the skin is explained on the basis of embryology and histology and the main features of tumor-associated syndromes are summarized. Moreover, some conceptual controversies and problems in differential diagnosis of cutaneous adnexal tumors are discussed.

Abstract
The uterine fibroid is a benign tumour. The prevalence, in all the population, is 50% for european women and 80% for black women. 30% of fibroids are symptomatic. The new FIGO classification gives 7 positions (0 to 7), submuccus (0, 1, 2), interstitial (3, 4, 5), subserous (6, 7). Diagnosis is performed by 2D and 3D ultrasound which could be associated by hysterosonography. Hysteroscopy and MRI could be proposed. Hysterectomy is the main treatment, if possible by vaginal or laparoscopic way. Conservative treatment (myomectomy) could be realized by hysteroscopic, laparoscopic way or laparotomy for patients who desire to preserve fertility. Arteries embolisation is an alternative to hysterectomy or myomectomy for patients without desire of pregnancy. Preoperative treatments by GnRH agonist or SPRM like ulipristal acetate treat anaemia, decrease the myoma volume and could modify the therapeutic strategy.

Abstract
The establishment of the clinical behavior of uterine smooth muscle tumors /USMT/ is an essential stage of modern diagnostics. There are significant differences in the criteria determining the malignant potential of smooth muscle gynecological tumors. Generally USMT generating diagnostic problems are classified into: clinically benign tumors; clinically malignant tumors with benign morphological features; smooth muscle tumors of uncertain malignant potential (SMTUMP) and lesions whose smooth muscle differentiation is not obvious. The knowledge in this area is essential for an adequate therapeutic approach.

Abstract
In November 2010, the International Federation of Gynecology and Obstetrics formally accepted a new classification system for causes of abnormal uterine bleeding in the reproductive years. The system, based on the acronym PALM-COEIN (polyps, adenomyosis, leiomyoma, malignancy and hyperplasia-coagulopathy, ovulatory disorders, endometrial causes, iatrogenic, not classified) was developed in response to concerns about the design and interpretation of basic science and clinical investigation that relates to the problem of abnormal uterine bleeding. A system of nomenclature for the description of normal uterine bleeding and the various symptoms that comprise abnormal bleeding has also been included. This article describes the rationale, the structured methods that involved stakeholders worldwide, and the suggested use of the International Federation of Gynecology and Obstetrics system for research, education, and clinical care. Investigators in the field are encouraged to use the system in the design of their abnormal uterine bleeding-related research because it is an approach that should improve our understanding and management of this often perplexing clinical condition.

Abstract
Uterine sarcomas are a heterogeneous group, which constitutes about 8% of malignant uterine tumors. This heterogeneousness and rare occurrence were the main cause of non-uniform therapeutical management. In previously published papers, there were mainly retrospective assessments of the experience of individual centres. The basis of relevant conclusions of the studies, beside their prospectiveness, is the use of unified classification criteria. Currently, a completely new classification of uterine sarcomas is being used, which consists of leiomyosarcoma, endometrial stromal sarcomas and adenosarcomas. For classification of carcinosarcomas, there are valid new criteria of endometrial cancer classification. The basic therapeutic approach of leiomyosarcoma and endometrial stromal sarcomas is a surgical intervention. The gold standard is hysterectomy and salpingooophorectomy. Justifiability of lymphadenectomy is being discussed. For carcinosarcomas, the same recommendations as for the surgical treatment of prognostically unfavourable endometrial carcinoma are valid - hysterectomy, salpingooophorectomy, pelvic and paraaortal lymph node dissection and omentectomy. It is necessary to implement the new classification into clinical practice, to publish and evaluate existing papers, which take into account their basic thesis. Only then it will be possible to create unified therapies. They should be aimed to improve patients survival.

Abstract
OBJECTIVE Review of new staging systems for gynaecological cancers and their impact on prognosis and planning treatment. DESIGN Review article. SETTING Department of Gynaecology and Obstetrics, First Faculty of Medicine and University Hospital Na Bulovce, Charles University, Prague; Department of Radiotherapeutic Oncology, First Faculty of Medicine and University Hospital Na Bulovce, Charles University, Prague; Department of Pathology, University Hospital Na Bulovce, Prague. RESULTS Every staging system should have 3 basic characteristics: it must be valid, reliable, and practical. Over the years, these staging classifications--with the exception of cervical cancer and gestational trophoblastic neoplasia--have shifted from a clinical to a surgical-pathological basis. Changes based on new findings were proposed in 2008 by the FIGO Committee on Gynecologic Oncology, approved in September 2008 by the FIGO Executive Board, and published in 2009. The greatest changes were made in the new staging system for carcinoma of the vulva and others in the new staging systems for carcinoma of the cervix and carcinoma of the endometrium. A new stanging system was also created for uterina sarcomas, based on the criteria used in other soft tissue sarcomas. A clinical staging system for carcinoma of cervix continues because surgical staging cannot be employed worldwide (especially in third world countries). Stage 0 has been deleted from the staging of all tumours, since it is pre-invasive lesion and it is not an invasive tumour. In the revised staging system for carcinoma of the endometrium, four fundamental changes have occurred, which will be discussed. Carcinosarcoma is still staged identically to carcinoma of the endometrium. A completely new staging system was created for adenosarcomas, along with an almost identical staging system for leiomyosarcoma and endometrial stromal sarcoma. The staging system for carcinoma of ovary and Fallopian tube remains without changes. CONCLUSION Since medical research and practice in the field of oncology have shown explosive growth, the staging of some of the gynaecological cancers did not give a good spread of prognostic groupings. Therefore, revised FIGO and TNM staging system has been structured to represent major prognostic factors in predicting patients' outcomes and lending order to the complex dynamic behavior of gynaecological cancers. The purpose of good staging system is to offer a classification of the extent of gynaecological cancer in order to provide a method of conveying one's clinical experience to others for the comparison of treatment methods.

Abstract
Neoplasm staging system was created to facilitate making diagnoses and planning treatment for cancer patients. Since medical research and practice in the field of oncology have shown explosive growth, the staging of some of the gynecologic cancers did not give a good spread of prognostic groupings. In the light of these breakthroughs, the following changes to the staging of gynecological cancers were proposed and approved by the FIGO Committee. In vulvar cancer Stage IA remained unchanged but Stage I and II have been combined. The number and morphology of the involved nodes have been taken into account, and the bilaterality of positive nodes has been discounted. In cervical cancer Stage 0 has been deleted and substages in Stage IIA have been included. In endometrial cancer Stage IA and IB have been combined so that now Stage IA involves the endometrium and/or less than one-half myometrial invasion and IB is equal to or greater than the outer one-half of the myometrium. Stage II no longer has a subset A and B. Involvement in the endocervical glandular portion of the cervix is now considered Stage I. Pelvic and para-aortic node involvement have been separated. The committee has also established a sarcoma staging system based on the criteria used in other soft tissue sarcomas.

Abstract
Uterine leiomyomas (fibroids, myomas) are a common benign disease of the uterus with a prevalence of 8-18%. Prevalence rates vary with race, and fibroids are most common in African American women. Uterine leiomyomas can also be present during pregnancy, which may occur more frequently than previously suspected, with prevalence rates reported of up to 10%. Recent evidence has emerged to clarify the relationship of uterine fibroids on fertility and obstetrical outcomes. In this paper we review evidence that uterine fibroids, specifically submucosal and intramural myomas, negatively impact fertility and are associated with adverse obstetrical outcomes such as: pain, preterm labor, placental abruption, malpresentation, postpartum hemorrhage, and cesarean section. Myomectomy performed for submucosal and intramural fibroids significantly improves fertility outcome, and current evidence suggests myomectomy is the treatment of choice in women desiring to conceive. For women that do not desire surgery, medical management of myomas is available. Treatment with GnRH agonists may be considered, however newer medications with fewer side effects give practitioners and patients more options. Progesterone antagonists, selective progesterone receptor modulators, and aromatase inhibitors have all shown promise as effective therapies. Non-pharmacologic treatments such as uterine artery embolization and MRI-guided ultrasound have also emerged as effective treatments for uterine fibroids. With such a wide range of new and emerging treatment options, it is important for providers to understand which fibroids are likely to respond optimally to a specific treatment, in order to individualize appropriate and effective management for patients.

Abstract
OBJECTIVE To investigate whether polymorphism in CYP17A1 gene is associated with uterine leiomyomas (ULM) and to evaluate differences in epidemiologic and genetic factors among solitary and multiple leiomyomas. DESIGN Prospective case control study. SETTING Tertiary gynecology department. PATIENT(S) One hundred eighty-one women with clinically and surgically diagnosed ULM, 41 healthy control subjects, and 92 population control subjects. INTERVENTION(S) Completing the questionnaires, peripheral venous puncture. MAIN OUTCOME MEASURE(S) Polymerase chain reaction and restriction-fragment-length polymorphism analyses were performed to genotype women regarding the CYP17A1 -34 A/G (rs743572) gene polymorphisms. Epidemiologic data was collected by questionnaire and compared between women with ULM and healthy control subjects. RESULT(S) Women with multiple ULM had higher prevalence of positive family history, lower age at menarche, lower parity, higher percentage of smoking, younger age at first sexual intercourse, lower prevalence of CYP17A1 AA genotype and lower CYP17A1 A allele frequency than healthy control subjects. These trends were not apparent among women with solitary ULM. CONCLUSION(S) Carriage of CYP17A1 AA is protective for developing ULM in our population. Women with solitary ULM mostly resembled healthy control subjects, whereas women with multiple ULM differed in CYP17A1 AA genotype and external stimuli.

Abstract
The IETA (International Endometrial Tumor Analysis group) statement is a consensus statement on terms, definitions and measurements that may be used to describe the sonographic features of the endometrium and uterine cavity on gray-scale sonography, color flow imaging and sonohysterography. The relationship between the ultrasound features described and the presence or absence of pathology is not known. However, the IETA terms and definitions may form the basis for prospective studies to predict the risk of different endometrial pathologies based on their ultrasound appearance.

Abstract
OBJECTIVE To describe new diagnostic approach to complete hydatidiform mole, immature complete hydatidiform mole, partial hydatidiform mole, proliferative mole and hydropic abortion. TYPE OF STUDY Original research. SETTING Trophoblastic Disease Center in the Czech Republic (TDC-CZ), Institute for the Care of Mother and Child, Prague. METHODS Our study consists of 1321 partial hydatidiform moles, 805 complete hydatidiform moles, 524 proliferative moles, and over 2500 hydropic abortuses diagnosed and treated at theTDC-CZ, besides which 2896 of these lesions were examined at the TDC-CZ by referral. The material was examined by routine histopathological methods, which in selected cases was supplemented by immunohistological examination and correlated with cytogenetic and molecular genetic results and clinical features. RESULTS The study describes the diagnostic procedures enabling the differential diagnosis between mature complete hydatidiform mole, immature complete hydatidiform mole, partial hydatidiform mole, proliferative mole and hydropic abortion. Fourteen histological parameters have been defined which are most common, individually or in combination, in various types of hydatidiform moles and hydropic abortions. Warning is given to errors in histological diagnosis correlated with cytogenetic and molecular genetic results. Proposed reliable method of eliminating the influence of these errors on the possible development of trophoblastic disease. CONCLUSION The study describes differential diagnosis of complete hydatidiform mole, immature complete hydatidiform mole, partial hydatidiform mole, proliferative mole, hydropic abortion and relevant clinical management.

Abstract
OBJECTIVE To value a new presurgical classification system of submucous myomas for predicting the difficulty and the safety of hysteroscopic myomectomy. METHODS The clinical data of 491 patients who underwent hysteroscopic resection of submucous myomas were analyzed. The myomas were classified according to the Classification of the European Society for Gynaecological Endoscopy (ESGE) and our group's new classification, which consists of five parameters. The possibility of total resection of submucous myoma, the operating time and the frequency of any complications were considered. RESULTS The ESGE classification showed significant differences between the level 0 and level I or II (both P < 0.01). Hysteroscopic myomectomy was considered incomplete in 9 patients with myomas. The numbers of complete surgeries of level II was significant lower compared to level 0 or level I (P < 0.01). Using our new classification, the differences of both operating times and the numbers of complete surgeries between group B and A was significant (P < 0.01). CONCLUSION The new classification gives more clues as to the difficulties of hysteroscopic myomectomy than the standard ESGE classification. Although a larger number of patients need to be evaluated by this classification.

Abstract
OBJECTIVE To determine the prognostic accuracy of current diagnostic criteria for uterine smooth muscle tumors. STUDY DESIGN Cases of uterine leiomyosarcoma (LMS) treated from 1976 to 1999 were analyzed retrospectively. Uterine LMS specimens were reevaluated using current criteria by a pathologist specializing in gynecologic diseases. Kaplan-Meier survival curves were evaluated. RESULTS Specimens were available from 67 patients diagnosed with uterine LMS. On rereview, only 47 specimens were thought to represent uterine LMS. The 20 other patients were deemed to have leiomyomas or leiomyoma variants, including 13 cellular leiomyomas, 5 atypical leiomyomas and 2 leiomyomas. Median survival for patients with uterine LMS was 2.1 years. (Ninety-seven percent of disease-specific deaths occurred within 6 years after the diagnosis.) With leiomyoma variants, median survival was > 25 years. Among these 18 women were 3 disease-specific deaths (all > 6 years after diagnosis). CONCLUSION Diagnostic criteria for uterine smooth muscle tumors require continued refinement. A small but significant number of patients diagnosed with leiomyoma variants will die of the disease. In contrast to the aggressive behavior of uterine LMS, disease-specific deaths attributed to leiomyoma variants occurred later. With this potential for delayed recurrence, these patients warrant close clinical surveillance.

Abstract
In the large group of uterine and ovarian tumors, the knowledge was updated in recent years substantially. New entities were defined and changes in classification of the lesions were performed. This review is limited to updates, such as evaluation of uterine smooth muscle tumors, new variants of uterine stromal tumors, uterine tumors resembling ovarian sex-cord tumor (UTROSCT), perivascular epithelioid cell tumors (PEC-omas), ovarian fibroma and fibrosarcoma, sclerosing stromal tumor and myxoma. Group of tumors of specialized gonadal stroma is not discussed as it represents particular area and thus requires a separated review article.

Abstract
It is proposed that a dynamic staging and risk factor scoring system is introduced for the classification of gestational trophoblastic disease as a logical development of the system presently used by the FIGO. Modern computer technology permits such change as the disease changes and particularly if it progresses. By allowing a change of both stage and risk factor score for each patient reported, a dynamic scoring system results. Moreover, such a system allows the introduction of more clinical detail than is permitted by the present FIGO system. FIGO combining its anatomic staging, first devised by Professor Song of Beijing, with the World Health Organization risk factor scoring, first devised by Professor Kenneth Bagshawe of Charing Cross Hospital, London, in 2002 was a significant progress. The most important change of the FIGO 2002 modification was that criteria were defined for the diagnosis of postmolar gestational trophoblastic neoplasia. However, hydatidiform mole still has no place in that classification. Also, the time when the staging occurs is not mandated. The present FIGO classification allows for no change in the status of the patient. A dynamic staging and risk factor scoring system would allow such changes to be recorded and, therefore, permit a more precise account of the patient's disease. A third issue is whether invasive mole should be included in the classification, as the Japanese Gynecologic Cancer Society insists is necessary. This problem may also be solved by the use of a dynamic risk factor scoring system.

Abstract
Adenomyosis of the uterus is a common condition amongst women in their reproductive years. It is defined as the presence of heterotopic endometrial glands and stroma in the myometrium with adjacent smooth muscle hyperplasia. The common presenting symptoms are painful and heavy periods and infertility, although many women are asymptomatic. Adenomyosis is thought to affect 1% of women and is typically diagnosed in the 4th and 5th decades of life. The aetiology is unclear, and until recently a diagnosis was made only after invasive and destructive surgery. With the advent of improved imaging of the pelvic organs, and in particular magnetic resonance imaging, the diagnosis of adenomyosis is being made more frequently. Unfortunately, because the disease has been infrequently diagnosed prior to hysterectomy, there are few well-designed studies of medical or surgical management. Management with hormonal treatment that aims to reduce the proliferation of endometrial cells is promising, but there is a paucity of well-designed studies to guide treatment. Hysterectomy or use of the levonorgestrel intrauterine system (LNG-IUS) remains the mainstay of treatment.

Abstract
Highly recurrent hydatidiform moles (HMs) studied to date are not androgenetic but have biparental genomic contribution (BiHM). Affected women have an autosomal recessive mutation that causes their pregnancies to develop into HM. Although there is genetic heterogeneity, a major locus maps to chromosome 19q13.42, but a mutated gene has not yet been identified. Molecular studies have shown that maternal imprinting marks are deregulated in the BiHM trophoblast. The mutations that cause this condition are, therefore, hypothesized to occur in genes that encode transacting factors required for the establishment of imprinting marks in the maternal germline or for their maintenance in the embryo. Although only DNA methylation marks at imprinted loci have been studied in the BiHM, the mutation may affect genes that are essential for other forms of chromatin remodelling at imprinted loci and necessary for correct maternal allele-specific DNA methylation and imprinted gene expression. Normal pregnancies interspersed with BiHM have been reported in some of the pedigrees, but affected women repeatedly attempting pregnancy should be counselled about the risk for invasive trophoblastic disease with each subsequent BiHM.

Abstract
UNLABELLED Uterine smooth muscle tumors (SMTs) are usually recognized on the basis of their routine morphologic features; however, their distinction from endometrial stromal tumors (ESTs), the second most common mesenchymal tumor of the uterus, is sometimes problematic. Histone deacetylases (HDACs) were originally identified as nuclear enzymes regulating histone acetylation. We have recently shown that in normal human tissues, HDAC8 is exclusively expressed in the cytoplasm of cells showing smooth muscle differentiation. In this study, we examined HDAC8 expression in SMTs and ESTs of the uterus to determine whether HDAC8 may be a useful diagnostic tool in the classification of problematic uterine mesenchymal tumors. HDAC8 immunohistochemical staining was performed in 15 leiomyomas (LMs), 9 highly cellular leiomyomas (HCLs), 8 epithelioid SMTs, 13 leiomyosarcomas (LMSs), and 17 ESTs, including 3 with sex-cord differentiation and 5 with smooth muscle differentiation. All tumors were also stained for other smooth muscle markers (desmin, h-caldesmon, smooth muscle actin [SMA], smooth muscle myosin heavy chain) and for CD10. All LMs had moderate to strong expression of all smooth muscle markers. HDAC8 was detected in 8 of 9 HCLs and in all epithelioid SMTs (8 of 8); however, it was weak in 4 epithelioid SMTs. In contrast, desmin, h-caldesmon and smooth muscle myosin were positive in only 2 of 8, 1 of 8 and 4 of 8 epithelioid SMTs, respectively. All smooth muscle markers had similar frequency of staining in LMSs; however, HDAC8 showed overall moderate intensity compared with other smooth muscle markers, which showed stronger staining. HDAC8, h-caldesmon, and smooth muscle myosin did not stain conventional areas of ESTs or ESTs with sex-cord differentiation, whereas SMA and desmin were positive in those areas in 4 of 12 and 3 of 12 ESTs, respectively. Areas of smooth muscle differentiation in ESTs were positive for HDAC8 in all cases, but they were less constantly positive for the other smooth muscle markers. CD10 was expressed in most ESTs (14 of 17), but it was also positive in 15 of 45 SMTs. IN CONCLUSION 1) HDAC8 seems to be a specific marker of SM differentiation because conventional ESTs and ESTs with sex-cord differentiation are negative for HDAC8, whereas areas of smooth muscle differentiation in these tumors are consistently positive; 2) HDAC8 gives similar results to those obtained with desmin, h-caldesmon, and smooth muscle myosin in both LMs and LMSs, although the staining for HDAC8 in LMSs tends to be less intense; 3) HDAC8 may be a more sensitive marker than desmin and h-caldesmon in epithelioid SMTs. Thus, HDAC8 detection may be useful in helping the differential diagnosis of uterine mesenchymal tumors.

Abstract
A review of the literature is presented which deals with modern aspects of Muller mixed tumors (MMT) classification and problems of their histo- and morphogenesis, immunohistochemical, ultrastructural and molecular-genetic peculiarities. Prognostic factors and survival rates are considered. Further study of MMT is necessary for verification of their histo- and morphogenesis and for development of their classification.

Abstract
STUDY OBJECTIVE To develop a new preoperative classification of submucous myomas for evaluating the viability and the degree of difficulty of hysteroscopic myomectomy. DESIGN Retrospective study (Canadian Task Force classification II-3) SETTING University teaching hospitals. PATIENTS Fifty-five patients who underwent hysteroscopic resection of submucous myomas. INTERVENTION The possibility of total resection of the myoma, the operating time, the fluid deficit, and the frequency of any complications were considered. The myomas were classified according to the Classification of the European Society for Gynaecological Endoscopy (ESGE) and by our group's new classification (NC), which considers not only the degree of penetration of the myoma into the myometrium, but also adds in such parameters as the distance of the base of the myoma from the uterine wall, the size of the nodule (cm), and the topography of the uterine cavity. The Fisher's exact test, the Student's t test, and the analysis of variance test were used in the statistical analysis. A p value less than .05 in the two-tailed test was considered significant. MEASUREMENTS AND MAIN RESULTS In 57 myomas, hysteroscopic surgery was considered complete. There was no significant difference among the three ESGE levels (0, 1, and 2). Using the NC, the difference between the numbers of complete surgeries was significant (p <.001) for the two levels (groups I and II). The difference between the operating times was significant for the two classifications. With respect to the fluid deficit, only the NC showed significant differences between the levels (p = .02). CONCLUSIONS We believe that the NC gives more clues as to the difficulties of a hysteroscopic myomectomy than the standard ESGE classification. It should be stressed that the number of hysteroscopic myomectomies used in this analysis was low, and it would be interesting to evaluate the performance of the classification in a larger number of patients.

Abstract
Muller mixed uterine tumors (MMUT): nomenclature and classification of these tumors are very complicated. Benign variants of these tumors are not considered at all in modem WHO classification although they are described in the literature and occur in practice. Histogenesis and morphogenesis are still not clear. The authors consider MMUT as a group which includes tumors with different biological activity and various histo- and morphogenesis as well as prognosis.

Abstract
Ordinary and cellular leiomyomas of 147 patients (age 23 - 65 years) were studied histologically and immunomorphologically. Five females with rapidly growing tumors were operated after therapy with gonadotropines blockers. Variants with weak and pronounced proliferative activity of neoplastic myocytes and various activity of neoangiogenesis were distinguished. The latter may be either phases of development or different tumour types. Use of gonadotropine blockers inhibits myocyte proliferation and activates formation of stroma.

Abstract
BACKGROUND Based on a clinicopathologic study conducted at the University of Rostock, Germany, between 1/1997 and 6/2003, the histological records of 1761 patients who had been hysterectomized were evaluated. 1422 of these patients were suffering from smooth muscle tumours: 1389 were diagnosed as multiple leiomyomas, 26 as leiomyomas of uncertain malignant potential and 7 as leiomyosarcomas. PATIENTS AND METHODS The data about the microscopic findings were obtained by use of both conventional histology (HE and Giemsa) and immunohistochemistry with markers for leiomyosarcomas (desmin, actin, sm-actin, myoglobin, vimentin, MIB1) and evaluated by statistical methods. Three case reports are also presented: 2 patients with leiomyosarcoma and 1 patient with an UMP tumour. RESULTS The statistical evaluation included the frequencies of the different tumours subdivided into age groups, their localizations (with 23 distinctions), the associated microscopic findings (with 12 distinctions and most important combinations) and, finally, the number of tumours per patient and their (grouped) sizes. The case reports showed the presence of nuclear atypia, a heightened mitotic index and tumour cell necrosis. Immunohistochemical methods confirmed the histological diagnosis of a leiomyosarcoma. CONCLUSION In accordance with earlier studies, more than 95% of the smooth muscle tumours were leiomyomas. Leiomyosarcomas were rare (<1% in our study). In 3 out of 7 cases, a leiomyosarcoma had its origin in a leiomyoma.

Abstract
BACKGROUND The purpose of this study was to compare three-dimensional saline infusion sonohysterography (3D SIS) and diagnostic hysteroscopy for the diagnosis and classification of submucous uterine fibroids. METHODS This was a prospective double-blind study of 49 women who presented with a history of menorrhagia, diagnosed on non-enhanced two-dimensional ultrasonography with submucous fibroids. Fibroids were classified on 3D SIS according to the proportion of fibroid contained within the endometrial cavity, using the European Society of Hysteroscopy Classification of Submucous Fibroids. These results were then compared with the findings at diagnostic hysteroscopy. RESULTS A total of 61 submucous fibroids was identified in 49 symptomatic women. Diagnostic hysteroscopy confirmed these findings in all cases. There was agreement between the two methods in 11/12 cases of Type 0 fibroids (92%), 34/37 (92%) of Type I fibroids and 9/12 (75%) of Type II fibroids. The overall level of agreement was good with a kappa value of 0.80. CONCLUSIONS There is a good overall agreement between 3D SIS and diagnostic hysteroscopy in classification of submucous fibroids. Agreement is better in cases where a greater proportion of the fibroid is contained within the uterine cavity.

Abstract
OBJECTIVE Clinical- pathological features, typing, curability and pathogenesis of malignant tumors of trophoblast (MTT). DESIGN A retrospective analysis. SETTING Trophoblastic Disease Center in the Czech Republic (TDC-CZ), Mother and Child Care Institute, 3rd Medical Faculty, Charles University, Prague. METHODS Revision of 379 MITT cases treated at TDC-CZ and comparison of their histological picture with developmental stages of orthologic trophoblast from the standpoint of MTT typing and pathogenesis. The determination of curability of different histological types and risk stages (RS) used in TDC-CZ and a comparison with RS axccording to FIGO, WHO and NIH. Differentiation of undifferentiated choriocarcinoma (CH-Und) alias Epitheloid Trophoblastic Tumor (ETT) from the given cohort of MIT and establishment of its clinical and biological properties, curability and formal pathogenesis. RESULTS Three hundred and seventy nine MTT cases were classified into 5 histological types onthe basis of analogy with developmental stages of 7 to 14 days old trophoblast. 1: typical "classical" choriocarcinoma - No Special Type (CH-NST), which forms more than 80% of MTT. Moreover, the degree of differentiation of tumorous trophoblast and its prevailing (cytological) type made it possible to define other 4 types, i.e.: 2: CH-syncytio-trophoblastic (CH-Syn), representing 3.8%; 3: CH-cytotrophoblastic CH-Cyt with 3.3%; 4: CH-dissociated (CH-Dis), representing 6%; 5: CH-undifferentiated (CH-Und) with 6.8%. Mortality due to MIT of all mentioned types reached 94% until 1963, decreased to 43% until 1980 and has been 5.8% in the period of 1981-2004. In the latter period of time (1981-2004), mortality due to CH-Cyt proved to be 40%, that due to CH-Dis being 11%, and CH-Und 18%, though. Mortality of s.c. Placental Site Trophoblastic Tumor, which includes our CH-Cyt and CH-Dis therefore forms 21.4%. We have been using four RS in TDC-CZ. The following outline includes only the main features: 1st RT includes CH-NST < 30mm limited to uterus in connection with mole. 2nd RS includes CH-NST > 30mm after birth. 3rd RS includes CH-NST with multiple metastases outside GIT and CNS and MTT with the CH-Cyt, Dis, Und component < 75%. 4th RS includes CH-NST with metastases in CNS or GIT. MTT with CH-Cyt Dis, Ned component < 75% with metasteses and MTT with the same components > 75% In the last 23 years 1st RS and 2nd RS includes 85 % of all MTT in the TDC-CZ and curability is 100%. In the 3rd RS curability decreases to 64.3% and decreases to 55.6% in the 4th RS. According to FIGO classification the 1st RS forms 48%, 2nd RT represents 17% and 100% curability applies for both of them. 3rd a RS includes 20% of 100% curability, 3rd bc RS forms 10% with 67% curability and 4th abc RS includes 5 % with 50% curability. In using the WHO classification with four RS, their percentage representation is similar to our classification with similar curability; nevertheless the 1st RS and 2nd RS did not detect almost 8% of MTT, which ended with exitus. 3rd RS according to FIGO is overestimated in view of 100% curability and the abc degree in 1st and 2nd RS are only of theoretical significance and irrelevant for the choice of treatment. The closest results comparable with our classification were those of NIH. A very careful clinical-pathological analysis of 25 CH-Und-ETT, detected among 379 MTT revealed that CH-Und-ETT is anaggressive malignant form of CH, which is best derived from undifferentiated 7-8 days old trophoblast. It is insidious for its seemingly primary extragenital symptomatology in seven out of 25 cases, low hCG values and poor sensitivity to chemotherapy. CONCLUSION 1) The comparison of histological pictures of 379 MTT with developmental stages of orthologic trophoblast of 7-14 days old embryo was the basis for classification of 5 types of choriocarcinoma (CH): 1. Differentiated CH "No Special Type" (CH-NST), 2. Syncytiotrophoblastic CH (CH-Syn), 3. Cytotrophoblastic CH (CH-Cyt), 4. Dissociated CH (CH-Dis), and 5. Non-differentiated CH (CH-Und); 2) We have determined their percentual (and absolute) occurrence in the group of 379 MTT treated in CTN in the years 1955-2004. 3) We have described biological properties of individual types of CH and established the way they influence curability. 4) Four degrees of risk (RS) were specified in relation to 7 types of risk factors observed (1. size of tumor, 2. type of preceding pregnancy, 3. interval from pregnancy to the diagnosis, 4. histological type of CH, 5. number of metastases, 6. localization of metastases, 7. values of hCG). It has become obvious how RS influenced curability of CH (1st and 2nd RS forms 85% of all CH's and their curability is 100% (!), 3rd and 4th RS are represented in 15% and their curability is 64% in the 3rd RS and 55% in the 4th RS. 6) The curability reached in CTN was compared with that determined according to FIGO, WHO and NIH, respectively. The results proved to be similar, but in case of FIGO the 3rd degree was overestimated and the degrees abc in the 1st and 2nd RS were of theoretical importance only, therefore being of no values for the choice of treatment. Low and medium score according to WHO did not detect 8% of women who had died. The CH curability according to RS, having been recommended by NIH and used in the American Centers was virtually the same as our results. 7) It has been proved that the histological type of CH significantly influenced the determination of RS in the given patient. 8) CH-Und-ETT represents the least differentiated form of MTT, in other words choriocarcinoma. This is associated with a low production of HCG, mostly between 10(1) and 10(3) mIU/ml. 9) Pathogenesis of CH-Und ETT-ETT we derive from the earliest, undifferentiated stage of orthological trophoblast. The origin from the differentiated intermediate trophoblast chorion leeve we considerei improbable. 10) There are continuous transitions from CH-Und-ETT and PSTT to CH-NST, representing an analogy to grading in other malignant epithelial tumors.

Abstract
To explore the genetic origin of hydatidiform mole (CHM), 33 cases of CHM were collected mainly from Harbin Red Cross Central hospital from 1998.6 to 2001.5 and studied by multiplex-PCR, products were separated using denaturing polyacrylamide gel and were detected by silver stain for 9 different STR loci analysis. Among 33 samples of CHM, DNA from only paternal origin was found in 27 cases (81.8%, 27/33), and from both parents in 6 cases (18.2%, 6/33); and in the former, the homozygous CHM and the heterozygous CHM were 22 cases (66.7%, 22/33) and 5 cases (15.1%, 5/33), respectively. There was difference between analysis of microsatellite DNA polymorphism and pathological diagnosis in hydatidiform moles' classification. The results suggest that the analysis of 9 polymorphic STR loci is suitable for genetic original identification of hydatidiform moles.

Abstract
OBJECTIVE To evaluate the clinical usefulness of the "diagnostic score"for the detection of choriocarcinoma in persistent gestational trophoblastic disease without histologic findings. STUDY DESIGN We reviewed the clinical records of and histologic reports on all 809 patients with persistent gestational trophoblastic disease treated with surgery and chemotherapy in Japan. There were 347 cases of choriocarcinoma and 462 cases of invasive mole with histologic confirmation. We retrospectively applied the diagnostic score to all the patients. RESULTS The sensitivity of the score for choriocarcinoma (the true positive rate of the score for histologic diagnosis of choriocarcinoma) was 91.4%. The specificity of the score (the true positive rate of the score for the histologic diagnosis of invasive mole) was 94.1%. The accuracy of the score was 92.8%. CONCLUSION The diagnostic score is a unique scoring system for differentiating choriocarcinoma clinically from persistent gestational trophoblastic disease without histologic findings and for selecting the most appropriate chemotherapy. Proper management in the early stages strongly influences the outcome of these diseases. The scoring system should be very useful for comparing the nearly true incidence and treatment results with choriocarcinoma between nations.

Abstract
Endometrial carcinoma, the most common invasive neoplasm of the female genital tract, occurs either in a hormone-related, less virulent form (type I) or in a hormone-independent, more aggressive form (type II). Another cancer of the uterine corpus is carcinosarcoma, a biphasic or mixed epithelial-mesenchymal tumor, now classified as metaplastic carcinoma. We examined by karyotyping and comparative genomic hybridization a consecutive series of 67 endometrial carcinomas and 15 carcinosarcomas and compared the cytogenetic features of the different carcinoma subtypes. All three subtypes of uterine carcinoma had in common a nonrandom gain of material from 1q and 8q but differed from one another in other respects. Endometrial carcinomas of type I mostly presented gains from chromosome arms 1q and 8q and losses from Xp, 9p, 9q, 17p, 19p, and 19q, whereas endometrial carcinomas of type II showed a more complex imbalance picture, with gains from chromosome arms 1q, 2p, 3q, 5p, 6p, 7p, 8q, 10q, and 20q and losses from Xq, 5q, and 17p. The carcinosarcomas mostly showed gains of or from 1q, 5p, 8q, and 12q but losses from 9q, that is, they were much more similar to endometrial carcinomas in their pattern of acquired genomic changes than to sarcomas of the uterine corpus. It was also possible to identify different copy number changes among the different grades of type I carcinomas, between serous papillary and clear-cell carcinomas of type II, as well as between homologous and heterologous carcinosarcomas. Specifically, type I adenocarcinomas that were highly differentiated mostly showed gains from 1q and 10p; those that were moderately differentiated showed gains from 1q, 7p, 7q, and 10q as well as losses from Xp, 9p, 9q, 17p, 19p, and 19q; whereas those poorly differentiated showed gains from 1q, 2p, 2q, 3q, 6p, 8q, and 20q but losses from Xp, Xq, 5q, 9p, 9q, 17p, and 17q. The serous papillary carcinomas showed gains from 1q, 2p, 2q, 3q, 5p, 6p, 6q, 7p, 8q, 18q, 20p, and 20q but losses from 17p, whereas the clear-cell carcinomas showed gains from 3q, 7p, 8q, 10q, 16p, and 20q but losses from 6q. Finally, the homologous carcinosarcomas presented gains from 1p, 1q, 8q, 12q, and 17q as well as losses from 9q and 13q, whereas the heterologous tumors showed gains from 1q, 8p, and 8q. The reproducibility of the observed correlations between karyotypic aberration patterns and histological differentiation was underscored by the fact that those carcinosarcomas whose epithelial component resembled type I endometrial carcinomas also exhibiting a type I aberration profile, whereas carcinosarcomas with a type II carcinoma differentiation had karyotypic abnormalities similar to those of type II endometrial carcinomas.

STUDY DESIGN Four leiomyosarcomas and 21 carcinosarcomas (homologous and heterologous) treated at the Saitama Cancer Center from 1991 to 2000 were analyzed macroscopically and microscopically. RESULTS Of 4 leiomyosarcomas, 3 were intramuscular, localized type, with a negative diagnosis for sarcoma. Of 21 carcinosarcomas, 7 were exophytic type with little necrosis (B-1), 5 were exophytic type with marked necrosis (B-2), 6 were exophytic type with a small sarcomatous component (B-3), and 3 were endophytic type (B-4). All endometrial smears were positive for sarcoma in B-1, whereas 5 of 14 (36%) were positive in the latter 3 types (B-2, 3 and 4). CONCLUSION In pure leiomyosarcomas, the sarcomatous portions are usually covered with normal endometrium. In carcinosarcomas, sarcomatous component is relatively limited in some cases and frequently covered with marked necrosis or carcinomatous tissue. These pathologically specific findings should make cytologic diagnosis difficult in uterine sarcomas.

Abstract
AIMS To determine the utility of p57kip2 in the diagnosis of hydatidiform mole. p57kip2 protein is a cyclin-dependent kinase inhibitor (CDKI) and is strongly paternally imprinted, being expressed from the maternal allele. It has been hypothesized that complete mole (CHM) with only the paternal genome would display reduced or nearly absent expression of p57kip2 compared to partial mole (PHM) having both paternal and maternal genomes. METHODS AND RESULTS The immunohistochemical expression of p57kip2 protein was investigated using paraffin-embedded tissue sections in histologically unequivocal cases of CHM (n = 51), PHM (n = 7), invasive mole (n = 1), and hydropic miscarriage (n = 2), as well as in histologically undetermined cases (n = 9). In the histologically unequivocal complete and invasive moles, expression of p57kip2 was absent except for one case in which villous cytotrophoblast covering the villous stroma was positive (51/52) as well as villous stromal cells (51/52). In contrast, it was strongly and continuously expressed in both villous cytotrophoblast and stromal cells in all cases of PHM and hydropic miscarriage. Among the nine histologically undetermined cases, five cases showing p57kip2 immunopositivity and hyperploid DNA were classified as PHMs, two cases showing p57kip2 immunonegativity and hyperploidy as CHMs, and two cases with p57kip2 immunopositivity and diploid DNA as hydropic miscarriage and diploid PHM, respectively, upon review of the histopathological findings. Intermediate trophoblast forming trophoblastic columns or anchoring villi and extravillous trophoblast at the implantation site showed variable expression of p57kip2 in all gestational conditions. Maternal decidua showed diffuse and strong p57kip2 expression, whereas syncytiotrophoblast was completely negative in all cases regardless of the diagnosis. CONCLUSIONS In summary, p57kip2 immunostaining results correlated well with morphological features of molar pregnancies and were helpful in determining histologically equivocal cases.
