Mixed endometrioid and clear cell carcinoma of the endometrium refers to a scenario in which the tumor exhibits histologic features of both endometrioid and clear cell carcinoma Endometriosis-associated cancers include clear cell and endometrioid ovarian carcinoma. A history of endometriosis has long been considered to be a risk factor for later development of these malignancies; however, recent molecular genetic evidence has provided unequivocal evidence that these lesions Several epidemiologic studies have shown that ovarian endometriosis is associated with an increased risk of developing ovarian endometrioid and clear cell carcinomas (CCCs) and a direct transition from ovarian atypical endometriosis to carcinomas has been described in 15-32% of cases (Figure 27.1) Often times, the diagnosis of UPSC is not made at the time of endometrial biopsy, as it may be admixed with another histologic subtype, such as a grade 3 endometrioid or clear cell carcinoma. From.. tumors (serous and mixed cell) - The BMI association is weaker in serous and mixed cell than in endometrioid tumors • BMI-associated estrogen driven proliferation is also important for serous and mixed cell, but maybe to a lesser extent • Additional mechanisms behind BMI other than estrogens - Chronic inflammation - Hili iHyper insu.

Mismatch repair deficient often shows mixed morphology, with clear cell and endometrioid components (J Natl Cancer Inst 2016;108:djv427) Only no specific molecular profile (p53, POLE and mismatch repair wild type) fit the classic clinical profile of clear cell carcinoma Usually, the low-grade part is endometrioid carcinoma type, and the high-grade part is either serous or clear cell carcinoma type A variety of factors are known to influence the development of Mixed Carcinoma of Endometrium including smoking, positive family history of endometrial cancer, and polycystic ovarian syndrome Sometimes, ovarian carcinomas with a predominantly endometrioid component are mixed with other epithelial types such as clear cell and serous carcinoma. A mixed epithelial tumor is diagnosed when 10% or more of a second or third type of epithelium is present. 1 About 10% of endometrioid carcinomas contain argyrophilic cells of neuroendocrine type

MATERIALS AND METHODS: Our immunohistochemical study set consisted of 47 endometriotic cysts containing clear cell carcinoma in 24 cases, well-differentiated ovarian endometrioid carcinoma in 20 cases, and mixed clear cell and endometrioid carcinoma in 3 cases Clear cell carcinoma is a Type II endometrial tumor that makes up less than 5% of diagnosed endometrial cancer. Like serous cell carcinoma, it is usually aggressive and carries a poor prognosis. Histologically, it is characterized by the features common to all clear cells : the eponymous clear cytoplasm when H&E stained and visible, distinct. Of the 12 cases, 9 were pure clear-cell carcinomas, and 3 were mixed types that included mixes with endometrioid carcinomas in 2 cases, and the remaining case was a heterologous-type carcinosarcoma that primarily consisted of a clear-cell carcinoma component and a scarce chondrosarcoma component Interestingly, a recent multi-institutional study of 41 cases of mixed endometrioid and clear cell endometrial carcinoma found that 66% had MMR protein deficiency by immunohistochemical analysis, a considerably higher rate than that observed in pure CCEC. 20 Identical staining patterns in the endometrioid and clear cell component suggest that.

Of the 58 mixed uterine papillary serous carcinoma cases, 45 (77.6%) patients had concurrent endometrioid adenocarcinoma, eight patients (13.8%) had clear cell carcinoma, and five patients (8.6%) had a concurrent component of undifferentiated carcinoma. The endometrioid component within mixed uterine papillary serous carcinoma cases was most.

  4. Introduction. Endometrial carcinoma is generally divided into two settings, type I and the type II, based primitively on whether or not it is estrogenic (Fig. 1). 1, 2 The distinction between these two settings could be easily understood by the clinicopathologic factors such as age, obesity, para-gravidity, presence/absence of hyperplasia and histological type, and also molecular disorders. 3.

The diagnosis of YST is supported by displaying clear and strong immunhistoochemical positive for AFP, SALL4, and GPC-3 (cytoplasm, nuclear, cytoplasm and membrane, respectively), while the CK7, PAX-8 and EMA (positive in clear cell adenocarcinoma and endometrioid carcinoma, but not in YST [32,33] were negative or weakly positive patchily.

Additionally, in one case of a mixed clear cell/endometrioid carcinomas, identical mutations in PTEN and TP53, as well as microsatellite instability, were identified in both components . The authors concluded that the tumors that are definable as clear cell carcinoma at the morphologic level are actually fairly heterogeneous, and may arise. Clear cell elements have been reported admixed with every type of primary carcinoma of the ovary, although endometrioid and serous tumours were the most common. 7, 8 The association of clear cell carcinomas with mucinous lesions has been reported only infrequently. One case was a clear cell carcinoma admixed with mucinous components comprising. Endometrioid Carcinoma is the third most common histotype of ovarian cancer and like clear cell carcinoma is believed to arise from endometriosis. This histotype of ovarian cancer is commonly diagnosed at a low stage and is low grade in more than 90% of cases In the retrospective cases, 4 cases were mixed with endometrioid carcinoma (Case 1, Case 2, Case 3, Case 5), 1 case had mixed clear cell carcinoma (Case 4), and only 2 cases had pure small cell neuroendocrine carcinoma (Case 6 and Case 7).

Endometrial Cancer Classification and Types of Endometrial Cancer. Most of the endometrial cancers are carcinomas (usually adenocarcinomas). They originate from the single layer of epithelial cells that line the endometrium. Type 1, Type 2, Mixed or undifferentiated carcinoma, Clear cell carcinoma, Serous carcinoma A frequent problem is to mistake a mixed carcinoma of the endometrium, composed of a grade 1 or 2 endometrioid adenocarcinoma and undifferentiated carcinoma, for an endometrioid adenocarcinoma of a higher grade (i.e., FIGO grade 2 or 3) because of the solid appearance of the undifferentiated component

Clear cell carcinoma of the womb lining is very rare. This is called a non-endometrioid cancer. It is a type 2 endometrial cancer. This is a more quickly growing type of cancer that is more likely to come back than other types, even if it is caught early Seven of 68 patients were mixed OCCC cases. Six of seven cases had clear cell and serous components, and one case, A-2486, consisted of three histologic regions: clear cell, serous, and endometrioid (Supplementary Table S3). Clinicopathologic characteristics are summarized in Supplementary Fig. S3 high‐grade serous carcinoma and a high‐grade endometrioid carcinoma, or between a clear cell carcinoma and clear cell areas within a high‐grade serous carcinoma or an endometrioid carcinoma.

Similar to the pathogenesis of serous carcinoma, it has been proposed that endometrioid and transitional cell tumors also follow low- and high-grade pathways of pathogenesis. 11,18 However, ovarian clear cell CA has p53 mutations only infrequently, and it usually exhibits a low to moderate level of chromosomal instability. 1,9,14,16,22,37,38,51. e Undifferentiated and mixed histology subtypes: undifferentiated carcinomas (a), mixed low-grade endometrioid carcinoma with serous carcinoma (b), mixed endometrioid and clear cell carcinoma (c) and mixed serous and clear cell carcinoma (d). Rows indicate genes and columns represent tumour cases [14-20] In the retrospective cases, 4 cases were mixed with endometrioid carcinoma (Case 1, Case 2, Case 3, Case 5), 1 case had mixed clear cell carcinoma (Case 4), and only 2 cases had pure small cell neuroendocrine carcinoma (Case 6 and Case 7). The patient in this case report had L/SCNEC with serous carcinoma, which further confirms that. Mixed carcinomas are uncommon, probably accounting for < 1% of EOCs, and most represent mixed endometrioid and clear cell carcinomas. Each of the five main subtypes of EOC has a different underlying pathogenesis and is associated with distinct molecular events, clinical behavior, response to traditional chemotherapeutic agents, and prognosis Endometrioid Epithelial Tumors General features Most endometrioid tumors are epithelial and account for about 3% of all ovarian tumors. Endometrioid carcinomas account for 10-15% of ovarian carcinomas and at least 50% of stage I carcinomas. Endometrioid stromal sarcomas, mesodermal adenosarcomas, and malignant mesodermal mixed tumors are considered under separate headings. Benign.

Uterine papillary serous and clear cell cancer. INTRODUCTION — The uterine papillary serous (UPSC) and clear cell types of endometrial cancer, which account for less than 15 percent of all endometrial cancers, are biologically more aggressive than usual endometrioid cancers Those with grades 1, 2, and 3 endometrioid carcinoma, serous carcinoma, clear cell carcinoma, carcinosarcoma, and mixed carcinoma were included in this study. Patients with other histological types, complicated with other carcinomas, and lack of either clinical information or surgical specimens were excluded

There was also evidence of a right ovarian mixed endometrioid adenocarcinoma grade 2 with a minor component of clear cell carcinoma and a left ovarian clear cell carcinoma of 0.5 cm . One right and one left external iliac sentinel nodes were negative on ultrastaging analysis (Online supplementary table 1) In the 5 cases of metastatic clear cell carcinoma, PAX8 was expressed in all cases (100%) and WT1 in only 1 case (20%). In the 9 cases from patients whose primary ovarian carcinoma showed mixed components, the detection rate using PAX8 was 8 (89%) of 9 cases, and using WT1, the detection rate was 6 (67%) of 9 cases Fertility-sparing treatment is contraindicated in patients with high-grade endometrioid adenocarcinomas, uterine papillary serous carcinoma, clear cell carcinoma, or carcinosarcoma. In young women with stage IA or IB endometrioid adenocarcinoma, ovarian preservation is safe and recommended

Papillary clear cell carcinoma differs from papillary serous carcinoma in two ways: (1) in clear cell carcinomas, glands or papillae are lined by a single layer of polyhedral cells, with uniform nuclei and prominent nucleoli ( Fig. 19.31A and B ); and (2) in contrast to serous carcinomas, prominent exfoliation is typically absent OV901: Multiple ovary tumor with matched cancer adjacent ovary tissue array, including serous carcinoma,clear cell carcinoma,endometrioid adenocarcinoma,mucinous adenocarcinoma,disgerminoma,yolk sac tumor and sertoli-Leydig cell tumors and mixed germ cell tumor,thology grade, TNM and clinical stage (AJCC 8.0), 76 cases/90 cores (1.5mm The entities covered in this chapter are uterine serous carcinoma (USC), carcinosarcoma, and clear-cell carcinoma together with tumors of mixed histology. Overall, these represent 3-10 % of all endometrial cancers but they are responsible for a significant percentage of endometrial cancer mortality Type II (papillary serous and clear cell) endometrial carcinoma (EC) is a rare subgroup and is considered to have an unfavorable prognosis. The purpose of this retrospective analysis was to elucidate the meaning of adjuvant radiotherapy (RT) for clinical outcome and to define prognostic factors in these patients (pts). From 2004-2012 forty-two pts with type II EC underwent surgery followed by.

Through the central pathological review, 33 cases were excluded and 340 cases were included in our study. The reasons of exclusion were as follows: 9 cases with mixed carcinoma, 7 cases with serous carcinoma, 3 cases with carcinosarcoma, 1 case with clear cell carcinoma, and 12 cases with ovarian cancer, and 1 case with cervical carcinoma . The. Ovarian cancer with LS is frequently of the endometrioid/clear cell carcinoma histological type [3, 9, 10]. Ovarian clear cell carcinoma (OCCC) is the second reported subtype of ovarian epithelial carcinoma that is closely related to LS, with a mean age at diagnosis of 55 years, and is strongly associated with endometriosis and adenofibromatous.

Endometrial carcinoma is the most common gynecologic malignancy in developed countries [].It comprises several pathological subtypes, such as endometrioid, mucinous, clear cell, mixed cell, undifferentiated, and dedifferentiated carcinoma[].The last two entities are recently defined to distinguish them from other less aggressive tumors, therefore, providing proper treatment for patients Background The molecular biology and cellular origins of mixed type endometrial carcinomas (MT-ECs) are poorly understood, and a Type II component of 10 percent or less may confer poorer prognoses.
