The diagnostic distinction between endometrial serous carcinoma (ESC) and endometrial clear-cell carcinoma (CCC) may occasionally be problematic, and one potentially contributing factor is the finding of clear cells in otherwise classic cases of ESC Clear cell carcinoma is the least common of the malignant transformations reported in nonpelvic sites of endometriosis. Two cases with clear cell carcinoma transformation arising from endometriosis in abdominal wall scars are presented
Clear Cell carcinoma of the uterus is an uncommon type of endometrial cancer and is considered a high risk group (greater chance of relapse or recurrence than the more common type called adenocarcinoma.) Most authorities recommend additional therapy after surgery, though there is no consensus on what's best, radiation (whole abdomen WART, or pelvis) and/or chemotherapy Clear cell carcinoma of the ovary has distinct biology and clinical behavior. There are significant geographical and racial differences in the incidence of clear cell carcinoma compared with other epithelial ovarian tumors. Patients with clear cell carcinoma are younger, tend to present at an early stage, and their tumors are commonly associated with endometriosis, which is widely accepted as. Clear Cell Carcinoma of Endometrium is a rare subtype of endometrial cancer, which begins in the lining of the uterus (the endometrium). The majority of these cancer cases are detected and diagnosed in women aged 50 years and older (postmenopausal women What is the natural of history of clear cell carcinoma arising in endometriosis? Endometriosis, which is common among women of reproductive age, suggests the presence of functioning endometrial tissues outside the uterus.3Patientswith clear cell carcinoma arising in endometriosis often have a history of uterine surgery, especially cesarean section. . The time between surgery and cancer.
Clear cell carcinoma of the endometrium is a rare type of endometrial cancer that is generally associated with an aggressive clinical behaviour. Here, we sought to define the repertoire of somatic genetic alterations in endometrial clear cell carcinomas (ECCs), and whether ECCs could be classified into the molecular subtypes described for. Uterine clear-cell carcinoma (CC) is a rare form of endometrial cancer with distinct morphological features on pathology; it is aggressive and has high recurrence rate. Like uterine papillary serous carcinoma CC does not develop from endometrial hyperplasia and is not hormone sensitive, rather it arises from an atrophic endometrium regarded as high-grade/type II endometrial carcinoma, remains controversial. Clear cell adenocarcinoma (CCA) and serous adenocarcinoma (SEA), categorized as high-grade/type II tumor, have been proven to have, respectively, the abnormalities of AT rich interactive domain 1A (ARID1A), phosphatidylinositol 3-kinases (PI3K) and hepatocyt 244 Document heading doi: 10.1016/S2305-0500(13)60155-4 P rimary abdominal wall clear cell carcinoma arising from incisional endometriosis B urcu G undogdu 1 , Isin U reyen 1 * , G unsu K imyon 1 , H akan T uran 2 , N urettin B oran 1 , G okhan T ulunay 1 , D ilek B ulbul 3 , T aner T uran 1 , M F aruk K ose 1 1 Gynecologic Oncology Division, Etlik Zubeyde Hanim Women â€™ s Health.

Clear cell carcinoma (CCC) of the abdominal wall arising from endometriosis is a rare entity with less than 40 cases reported in the literature. In fact, the probability of developing endometriosis in a surgical scar is roughly 0.03-1% and its risk of malignant transformation around 0.3 to 1%. endometriosis to cancer can be classified as follows: transformation to ovarian clear cell carcinoma at the ovary, to extragonadal clear cell carcinoma, or to other extragonadal carcinoma. Studying 222 malignant tumors originating from endometriosis, Irvin and Perkey found 169 ovarian and 53 extragonadal cases . The most common site o
We herein report a case of clear cell carcinoma arising from endometriosis in the groin in a 53-year-old woman. The findings of MRI and FDG/PET-CT indicated a malignant tumor, and surgical biopsy confirmed adenocarcinoma of the female genital tract. The tumor including a part of the abdominal rectus muscle and rectus sheath, subcutaneous fat, skin, and the right inguinal ligament was resected. Malignant endometriosis in an episiotomy scar is rare; only seven cases have been reported previously. Here, we compare two cases of benign endometriosis and clear cell carcinoma. The first case was a 54-year-old woman who presented with a large perineal lesion in her episiotomy scar with high 18F-fluorodeoxyglucose uptake. This location had a history of endometriosis many years ago 52 year old woman with clear cell carcinoma of the cervix exhibiting choriocarcinomatous differentiation and mismatch repair protein abnormality (Int J Gynecol Pathol 2017;36:323) 56 year old woman with clear cell carcinoma of the uterine cervix and cervical endometriosis (Int J Gynecol Pathol 2018;37:88 My mom was diagnosed today (from debulking surgery) with Stage 3C clear cell ovarian carcinoma (CCC). CA-125 preop was 14.5, 15.1, 20 and CEA was 3. Intraoperatively, she was found to have endometriosis, the tumor was not arised from it
. Endometrial clear cell carcinoma is an uncommon histotype that has been under represented in prospective therapeutic trials (1-4).This tumor is less responsive to standard therapeutic regimens and may be amenable to targeted therapeutic approaches.However, the molecular pathogenesis of clear cell carcinoma, on which any such approaches would be based, is unclear () Malignant transformation to clear cell carcinoma from a focus of endometriosis on the abdominal wall is a rare and poorly understood complication. Most recent studies have shown that aggressive surgical resection with safety margins associated with lymphadenectomy is still the most effective treatment with the highest survival rates Uterine clear-cell carcinoma (CC) is a rare form of endometrial cancer with distinct morphological features on pathology; it is aggressive and has high recurrence rate. Like uterine papillary serous carcinoma CC does not develop from endometrial hyperplasia and is not hormone sensitive, rather it arises from an atrophic endometrium. Such lesions belong to the type II endometrial cancers
Several studies have since indicated that women with endometriosis carry an increased risk of developing epithelial ovarian cancer (EOC), especially of the clear cell and endometrioid histologic sub-types , . Ovarian clear cell carcinoma (OCCC) represents 12% of cases of EOC in Western countries  Pathological analysis indicated clear cell carcinoma of the perineum incision, possibly arising from an endometrial implant (Fig. 2 a-c). A transitional dysplastic zone between the endometriotic focus and the clear cell carcinoma was identified (Fig. (Fig.2d). 2 d). Each side of the superficial inguinal region had one positive lymph node Considered as the precursor lesion of a subset of ovarian clear cell carcinoma (OCCC), the prognostic role of endometriosis in OCCC patients remains controversial. This study aimed to investigate the prognostic role of coexisting endometriosis in the survival of patients with OCCC, and also sought to identify other prognostic factors. A total of 125 patients were diagnosed with OCCC during the.
You may be offered chemotherapy after surgery for early stage, high-grade endometrial carcinoma (such as serous adenocarcinoma or clear cell adenocarcinoma). Carcinosarcoma may also be treated with chemotherapy after surgery. The chemotherapy drugs used to treat high-grade carcinomas include: cisplatin (Platinol AQ Natini Jinawath, Ie-Ming Shih, in Early Diagnosis and Treatment of Cancer Series: Ovarian Cancer, 2010. Clear Cell Carcinoma. Clear cell carcinoma is also frequently associated with endometriosis, clear cell adenofibromas, and clear cell atypical proliferative (borderline) tumors, but molecular evidence for the stepwise progression model is still lacking Clear cell carcinoma (CCC) of the uterine cervix is rare, and its etiology is unclear, except for reports of prenatal diethylstilbestrol (DES) exposure. In this case report of a 78-year-old postmenopausal Japanese woman with pelvic endometriosis, cervical CCC presented as a deep interstitial tumor, strongly suggesting the patient suffered from cervical endometriosis for a long time Introduction. Endometrial cancer remains the most common gynecological malignancy in the United States.1 Serous and clear cell histologies represent a rarer hormone-independent, aggressive subtype,2 which have been associated with higher rates of extra-uterine spread, as well as higher rates of recurrence.3 4 Treatment recommendations for early-stage endometrioid uterine cancer (International.
of clear cell CA [CC(AF+) and CC(AF-)] are more closely related to type I tumors. Key words: Ovary; clear cell carcinoma; adenofibromatous; endometriosis; pathogenesis. INTRODUCTION The dualistic model of ovarian carcinogenesis divides epithelial tumors into two groups designated type I and type II.40,41,59 Type I tumors are generall Epidemiology. Endometrial carcinoma is the most common gynecological malignancy, with peak incidence at around the 6 th decade, though 12% of cases present in premenopausal women.. The overall incidence is thought to be increasing. In the United States, there is a greater incidence among patients of European descent compared those of African American descent

Methods A retrospective chart review of patients diagnosed with clear cell ovarian cancer during January 1998-March 2013 was performed. All histopathology. Ovarian epithelial carcinoma (OECa), which consists of four histologically distinct subtypes, including serous (OSeCa), mucinous (OMuCa), endometrioid (OEmCa), and clear cell (OCCCa) types, has the worst prognosis of all gynecological malignancies .Of these, OCCCa is not just another type of OECa, but a distinct entity with a specific etiology and biological composition 
Endometrial clear cell carcinoma is an uncommon endometrial cancer that is biologically, clinically, and pathologically distinct from the more common endometrioid and serous carcinomas. The differential diagnosis for endometrial clear cell carcinoma includes benign and nonneoplastic lesions, as well as a variety of neoplastic processes that may potentially display clear cells A pooled analysis of case-control studies included 13,226 controls and 7,911 women with ovarian malignancy and concluded that endometriosis is associated with certain histology subtypes including clear cell carcinoma (CCC) (20.2%), endometrioid carcinoma (13.9%), and low-grade serous carcinoma (9.2% Clear Cell Carcinoma of the Inguinal Region Arising From Endometriosis Geung Hwan Ahn, MD, and Robert E. Scully, MDt The second and third examples of clear cell carcinoma of the inguinal region arising from endometriosis are reported. In one patient a right inguinal mass was excised along with an inguinal lymph node dissection of clear cell carcinoma arising in endometriosis originally are diag-nosed as a subcutaneous mass. The tumor in this disease ranges widely in size, but it is usually large. In a review of 23 cases of endometriosis-associated clear cell carcinoma arising within cesarean section scars, the median diameter was 9 cm (range 2.5-22 cm).

carcinoma with glycogenation in foci of squamous differentiation, and endometrioid carcinoma with diffuse clear cells in glandular and/or solid areas from unknown causes (clear cell change NOS). The former is the most common cause of clear cell change in endometrial carcinomas, in the author's experience Although the disease is recognized as benign, endometriosis is occasionally accompanied by malignant ovarian tumors, especially endometrioid and clear cell adenocarcinomas [2,3,4,5,6,7,8,9]. However, to the best of our knowledge, the imaging features of malignant ovarian tumors have not been published in the English literature [ 10 , 11 ] A case of clear cell carcinoma arising from the endometriosis of the paraovarian cyst 61 Fig. 2. A unilocular cyst is seen with focal areas of solid papillary growth Overview. NCI Definition: A high-grade endometrial adenocarcinoma characterized by the presence of large neoplastic cells that display at least focal cytoplasmic clearing. The neoplastic cells form papillary, glandular, or sheet-like structures.  Endometrial clear cell adenocarcinomas most frequently harbor alterations in TP53, PIK3CA, ARID1A, PPP2R1A, and SPOP 
HNF1B has high sensitivity for endometrial clear cell carcinoma, but its specificity is lower than in ovarian clear cell carcinoma. Moreover, there are different antibodies against HNF1B, which vary in quality. Use of monoclonal Napsin A is recommended, as the polyclonal antibody lacks specificity 56 However, no unambiguous endometrial glands and/or endometrial type stroma were identified in close proximity to the tumor according to the authors. 7 In our case, we have documented dysplastic clear cell changes within the endometriotic glands in the colonic wall present simultaneously with a nearby clear cell carcinoma of the colon Clear cell carcinoma of the ovary is the least predominant type of epithelial ovarian cancer representing only 6% of all histologic types . An association of endometriosis as a precursor to clear cell and endometrioid carcinoma has been postulated in the current model of ovarian carcinoma . We present two cases of clear cell carcinoma arising. Keywords: Endometriosis, Clear cell carcinoma, Episiotomy scar, Malignant transformation Background Endometriosis is a common disease in women and is characterized by the presence of ectopic functional endometrial tissue as an inflammatory condition . Endometriosis can occur at any location, but the inci
Clear cell abdominal wall carcinoma, with papilar and tubule-cystic pattern, with intra-cystic growing, related with previous endometriosis (H&E). At evaluation after chemotherapy, the patient was asymptomatic and no other abdominal lesions were observed in MRI; CA125 levels decreased to 8.5 U/mL endometriosis that could progress to cancer. Ovarian clear cell carcinoma (OCCC) is a histologi-cal subtype of ovarian carcinoma showing distinctive epidemiological and clinical characteristics . Among early-stage ovarian cancer subtypes, OCCC has a favorable prognosis. However, among advanced-stage ovarian cancer subtypes, OCCC has a poor. Low grade endometrioid and clear cell uterine carcinoma. Endometrial cancer is the most common gynecologic malignancy, with 61,380 estimated new cases and 10,920 estimated deaths in 2017 . Approximately 75% of women are diagnosed with stage I disease, confined to the uterus, and have excellent 5-year survival . While the majority of patients.
Histologic Subtypes of Endometrial Cancer. Photomicrographs show (A) endometrial endometrioid carcinoma (International Federation of Gynecology and Obstetrics [FIGO] grade 1), (B) endometrial endometrioid carcinoma (FIGO grade 3), (C) endometrial clear cell carcinoma, and (D) endometrial serous carcinoma (A-D: H & E, original magnification ×20) Endometriosis has been identified as a precursor of clear cell carcinoma, which presumably accounts for the higher incidence of this histologic subtype (Taburiaux et al., 2015). The precipitant of the neoplastic event in the current study remains idiopathic, although one may conjecture that genetics, immunological or hormonal factors were. Clear cell carcinoma of the endometrium. AKA clear cell endometrial carcinoma. AKA endometrial clear cell carcinoma. General. Ten-year survival ~ 40%. Uncommon <=5 % of endometrial carcinomas. Type II endometrial cancer - estrogen-independent, usually post-menopausal women. Microscopic. Features Clear cell adenocarcinoma (CCA), a highly lethal histological subtype of ovarian carcinoma, is a type of human cancer with a high frequency of activating mutations in the PIK3CA gene. In this study, we aimed to determine how these mutations contribute to tumour development of CCAs Cell lines are extremely useful for both basic and clinical research. Thus, establishing endometrial cancer cell lines with malignant histology is important. This study aimed to extensively characterize an endometrial clear cell carcinoma cell line. This cell line, named 150,057, was derived from the endometrial clear cell cancer of a 63-year-old woman
Clear cell carcinoma (CCC) of the ovary comprises about 7.4% of ovarian carcinomas and 2.4% of ovarian epithelial neoplasms. The average age at the time of diagnosis ranges from 48 to 58 years. A close association between CCC and endometriosis has been documented in the previous series with documentation of transition from endometriosis to CCC in few series As compared with ovarian cancer without endometriosis, EAOC has been diagnosed in younger women and at an earlier stage. 7-9 Some studies have also reported a stronger association of endometriosis with ovarian clear cell carcinoma (CCC) and endometrioid carcinoma (EC) types of cancer. 2, 5, 8, 10 However, whether endometriosis is a prognostic.
Clear-cell carcinoma arising from the surgical cesarean section scar is very infrequent. The present study reports two patients with clear-cell carcinoma arising from an abdominal wall scar 20 and 23 years after their last cesarean section. Both Iranian patients had prior cesarean sections nearly 20 years earlier. Patients 1 and 2 had transverse and vertical abdominal incisions, respectively Clear cell carcinoma is the least common of the malignant transformations reported in nonpelvic sites of endometriosis. Two cases with clear cell carcinoma transformation arising from endo metriosis in abdominal wall scars are presented. ese patient Inclusion Criteria: Patients must have recurrent or persistent ovarian, fallopian tube, peritoneum, and endometrial clear cell carcinoma; primary tumors must be at least 50% clear cell histomorphology in order to be eligible or have a histologically documented recurrence with at least 50% clear cell histomorphology; in addition, the tumors should be negative for expression of Wilms tumor 1 (WT. endometrial clear cell carcinoma pathology pathology in outline format with mouse over histology previews Clear cell carcinoma of ovary with associated mucinous cystadenoma and endometriosis.
