Abstract
Endometriosis (EMS) is a rare condition in postmenopausal women. The incidence of transition from EMS to malignancy is as low as 1%, with endometrial stromal tumors (ESTs) occurring at an even lower incidence of 0.7%. Undifferentiated uterine sarcomas (UUSs) are a subtype of ESTs that account for 25% of all ESTs. Extrauterine UUSs are exceptionally rare, with only a few reported cases in the literature. We present the case of a woman who underwent surgery for deep infiltrating EMS and was later diagnosed with UUS, which originated from the bladder after surgical menopause.

Abstract
Extrauterine endometrial stromal sarcoma arising from malignant transformation of the vagina is an extremely rare condition. The diagnosis is often difficult as the symptomatology and pathological features overlap with that of pelvic endometriosis. A 38 years old female presented with complaints of dyspareunia, dysmenorrhea, and painful defecation along with blood-stained vaginal discharge for a year. Examination revealed the presence of multiple brownish irregular nodules in posterior vaginal fornix and fixed tender nodules which on biopsy revealed florid vaginal endometriosis. She improved symptomatically on medical therapy. After 18 months of diagnosis, she presented again with a necrotic growth in posterior fornix, which on repeat biopsy revealed a low-grade endometrial stromal sarcoma. Laparotomy revealed a 7×5 cm mass in the pouch of Douglas, infiltrating the posterior vaginal wall and rectum. A complete cytoreductive surgery with retrograde hysterectomy, excision of posterior vaginal wall and rectosigmoid resection was done. The patient is disease-free at a follow-up of 65 months.

Abstract
We report an exceptional case of an undifferentiated round and spindle cell sarcoma, occurring in the periprostatic region of a 54-year-old male, with a 'high-grade endometrial stromal sarcoma-like' (HG-ESS) morphology and harboring a ZC3H7B::BCOR gene fusion identified by RNA-based next-generation sequencing. In this report, we describe the striking overlap of morphologic, immunohistochemical and molecular features of this current case and previously reported similar cases with ZC3H7B::BCOR fusion-positive HG-ESS, and discuss the differential diagnosis and possible pathogenesis of this unusual entity.

Abstract
Low-grade endometrial stromal sarcoma (ESS) is a hormone-responsive low-grade sarcoma typically occurring in the uterine corpus in women. Their genetic hallmarks are recurrent gene fusions involving JAZF1, partnering with either SUZ12 gene or less commonly with PHF1. Low-grade ESS-like sarcoma, or endometrioid stromal sarcoma, is exceptionally rare in males and has been reported to date only in two cases, one in the paratesticular area and the other of prostatic stromal origin. We report herein two new cases of low-grade ESS-like sarcoma in male patients, one presenting as a periprostatic/peri-rectal mass with a JAZF1-GLI3 fusion, while the other as a paratesticular mass with a JAZF1-PHF1 fusion. As the GLI3 fusion appeared novel, we searched the transcriptional signature of 35 low-grade ESS from our archives and found a similar JAZF1-GLI3 fusion in a low-grade ESS arising from the uterine corpus, supporting a common pathogenesis. Histopathologically, both cases demonstrate cellular, monotonous proliferation of ovoid to fusiform cells with a background of arteriolar vascular network. Immunohistochemically, the neoplastic cells express ER, PR, and CD10, similar to ESS. One case also expresses diffuse and strong AR. On follow-up, the patient with the periprostatic mass recurred 2 years after initial surgery with peritoneal "sarcomatosis." We describe the salient diagnostic morphologic, immunohistochemical, and molecular features and discuss the differential diagnosis and possible pathogenesis of this unusual entity.

Abstract
Background This study aimed to analyze the clinical and pathological features of extrauterine endometrial stromal sarcoma (EESS) and explore an effective therapeutic regimen to reduce the recurrence rate in low-grade EESS patients. Methods Ten LG-EESS patients who were treated at the Chinese Academy of Medical Sciences Cancer Institute and Hospital from June 1999 to June 2019 were collected and analyzed. Results (1) Patient demographics are summarized in manuscript. Preoperative CA125 examination showed that 8 patients had a median level of 49.5 U/L (15.4–168.0 U/L). (2) All ten patients underwent tumor cytoreductive surgery. Five patients underwent optimal tumor resection and achieved an R0 resection. After the initial surgery, 7 patients who had multiple metastasis were treated with adjuvant chemotherapy, 2 patients with vaginal ESS were treated with chemotherapy and radiation therapy, and 6 patients with ER/PR positive received hormone therapy with or without chemotherapy. (2) Most EESS patients had multiple tumors. The omentum was the most commonly affected site, followed by the ovaries. (3) The median follow-up was 94 (range: 27–228) months, and recurrence was observed in 3 patients (n = 10, 30%) who underwent non-optimal surgery and no hormone therapy. The 5-year and 10-year DFS rates were both 70%, as shown in Fig. 2. OS was both 100% at 5 and 10 years. Conclusion As a conclusion, EESS is a rare disease and LG-EESS has a good prognosis. Surgery remains the available treatment for patients. LG-EESS has a risk of late recurrence which requires a long-term follow-up. With a limited sample size, our study shows optimal tumor reductive surgery and adjuvant hormone therapy may significantly reduce the risk of recurrence.

Abstract
Endometrial stromal sarcoma (ESS) is a rare uterine neoplasm infrequently arising in extra-genital sites. Herein, we report an extremely rare case of primary extra-genital ESS of transverse mesocolon occurring in a 51-year-old female presenting with gradually increasing abdominal mass. The clinical diagnosis considered was a gastrointestinal stromal tumor. Intra-operatively, the mass was confined exclusively to the transverse mesocolon. Microscopy revealed a cellular tumor composed of oval to elongate neoplastic cells with hyperchromatic nuclei, inconspicuous nucleoli and were immunoreactive for CD10, progesterone receptor (PR), estrogen receptor (ER), and PAX8; negative for KIT, CD34, SMA, S100, synaptophysin, chromogranin, WT-1, and calretinin. A distinct arborizing network of arterioles along with foci of endometriosis was also seen. We present this case for its extreme rarity and the challenges entailed in its diagnosis.

Abstract
Extrauterine endometrial stromal sarcomas (EUESSs) are rare tumours occurring without primary uterine involvement. They are classified as primary or secondary, depending on uterine involvement by stromal sarcomas. A 56-year-old woman who earlier underwent bilateral modified radical mastectomy for adenocarcinoma and total abdominal hysterectomy for endometrial stromal sarcoma, followed by tamoxifen therapy, presented with left loin pain. On evaluation, she had a left renal calculus with hydroureteronephrosis. Before percutaneous nephrolithotripsy, ureteroscopy revealed a polypoidal mass that was diagnosed as EUESS. The mass arose primarily within the ureteral lumen, with periureteric tissue uninvolved. She underwent left radical nephroureterectomy with adjuvant hormonal treatment. This is probably the first case of EUESS arising de novo from within the ureteral lumen without endometriosis, to be reported in medical literature. Immunohistochemistry facilitates earlier diagnosis. Cytoreductive surgery is the definitive treatment and multidisciplinary approach helps in overall survival of the patient.

Abstract
Endometriosis-associated ovarian malignancies have been well documented. Although these malignancies also occur as extraovarian lesions, little is known about them. Thus, this literature review aimed to further explore these rarely experienced tumors. A total of 257 published cases between April 1990 and April 2020 were found using PubMed, and 212 cases were included in the analysis considering Sampson’s criteria and the history of endometriosis. We classified these cases as follows: intestine, abdominal scar, vagina and vulva, peritoneum and deep endometriosis, urinary tract, uterine cervix, and others. Age of patients, history of endometriosis, types of past hormonal therapy, symptoms, histological types, and treatment were identified. The most common tumor site was the intestine. Endometrioid carcinoma was the dominant histological type. Contrary to the ovary, clear cell carcinoma was rare in extraovarian sites. On the other hand, clear cell carcinoma represented the largest number of abdominal scars. This difference may help us to understand the development of endometriosis-related malignancies. Hormonal treatment was mentioned in 67 cases and estrogen replacement therapy in 33 cases. Although risks of estrogen therapy are still controversial, the highly differentiated histological types and hormone-dependent characteristics of endometriosis-associated malignancy should be considered. Physicians should be careful about estrogen monotherapy after hysterectomy and long-term hormone replacement therapy in patients with a history of endometriosis.

Abstract
This report describes the clinical, radiographic, and pathologic findings in a female rhesus macaque that presented with acute abdominal distension and tympany. The macaque was euthanized after evidence of severe colonic distension on radiography and observation of widespread peritoneal adhesions on exploratory laparotomy. Gross and histopathologic evaluation revealed extensive entrapment of gastrointestinal and reproductive tracts by serosal fibrovascular proliferative tissue containing foci of endometriosis. The diagnosis of endometrial stromal sarcoma was supported by expression of CD10, Wilm tumor 1, estrogen receptor, and progesterone receptor and failure to express immunohistochemical markers characteristic of a range of differential diagnoses. In humans, this relatively uncommon neoplasm can arise from sites of endometriosis and often presents clinically as intestinal obstruction, similar to the presentation in this macaque.

Abstract
Endometrial stromal sarcoma (ESS) is a rare malignancy. Development of extrauterine ESS form endometriosis is particularly rare. The majority of extrauterine ESS occurs in areas with preexisting endometriosis. The most common site is the ovary. We experienced a case of ESS of the ovary that arose from endometriosis with multiple disseminated lesions. This disease was managed by total abdominal hysterectomy, bilateral salpingo-oophorectomy, both pelvic lymph nodes dissection, omentectomy, and appendectomy followed by postoperative high-dose progesterone therapy. Here, we report this case with literature review.

Abstract
STUDY HYPOTHESIS Loss of protein BAF250a (ARID1A) expression is present in women with rectovaginal deep-infiltrating endometriosis (DIE) and endometriosis affecting the pelvic sentinel lymph nodes (PSLN). STUDY FINDING Partial loss of protein BAF250a was found in some of our patient samples, comprising all endometriosis entities, including rectovaginal DIE and endometriosis affecting the PSLN. WHAT IS KNOWN ALREADY Loss of BAF250a (BRG-associated factor 250a)/ARIDIA (AT-rich interactive domain 1A) protein expression was identified among endometriosis-associated ovarian carcinomas and ovarian endometriosis, and this phenomenon was described as a possible early event in the transformation of endometriosis into cancer. DIE affecting the bowel/rectovaginal site is the most aggressive presentation of endometriosis and its 'risk' of malignant transformation has not been studied so far. STUDY DESIGN, SAMPLES/MATERIALS, METHODS We evaluated the immunohistochemical expression of BAF250a protein in 70 samples from patients enrolled in this study who were surgically treated at a tertiary center, university Hospital. The samples submitted to investigation were from rectovaginal DIE (n= 25/30), endometriosis affecting the PSLN (n= 5/7), ovarian endometriosis (n= 20/20) and endometrium from patients without endometriosis used as controls (n= 20/20). MAIN RESULTS AND THE ROLE OF CHANCE Partial loss (i.e. in one tissue section some cells stained positive for BAF250a while other cells, usually an adjacent group, were negative) of BAF250a protein was identified in 36% (9/25) of rectovaginal DIE samples, 40% (2/5) of endometriosis lesions involving the PSLN, 30% (6/20) of endometriomas, and also in 25% (5/20) of endometrium from controls. We found no statistical correlation between occurrence of partial loss of BAF250a protein and the use or not of hormone medications (P = 0.106), cycle phase (P = 0.917) and stage of disease (P = 0.717). LIMITATIONS, REASONS FOR CAUTION We only found partial loss of BAF250a protein expression, and in a small population of women, with relatively high frequency in all benign tissues assessed in the present analysis. Therefore, this finding alone should not be correlated directly with the risk of malignant transformation in these lesions. WIDER IMPLICATIONS OF THE FINDINGS The occurrence of partial loss of BAF250a protein expression in women with rectovaginal DIE and endometriosis affecting the PSLN is described for the first time. The value of this finding as a predictor of malignant transformation in endometriosis must still be clarified and further studied in association with other molecular events, such as PTEN (phosphatase and tensin homolog) deletion and PIK3CA (phosphatidylinositol-4,5-bisphosphate 3-kinase catalytic subunit alpha) mutation. We might then be able to identify in the future which patients with endometriosis are at higher risk of cancer. STUDY FUNDING AND COMPETING INTERESTS This study was supported by an internal Charité grant to the Endometriosis Research Center and the authors declare no conflicts of interest.

Abstract
Endometriosis is manifested by the presence of both endometrial glandular and stromal cells outside the uterine cavity. It is characterized by ectopic implantation of endometrial cells with elevated proliferation and migration. Endometriosis is the leading cause of morbidity among premenopausal women and the complex pathogenesis of this disease remains controversial despite extensive research. This rather complex disease has a significant impact on quality of life of many women as none of the current treatments represent a cure. Based on the current knowledge, one can conclude that the histological and genetic alterations in endometriosis might explain why and how endometriosis can change into several types of cancer. However, the exact mechanisms of this conversion are still not fully established.

Abstract
Like other stromal-derived gynecological tumors, a sclerosing stromal tumor of the ovary (SSTO) is a rare benign tumor that is difficult to distinguish from a malignant ovarian tumor in clinical practice. An SSTO is routinely treated with laparotomy. Here, we present two extremely rare cases of SSTO with contralateral and ipsilateral tubal pregnancies, in which laparoscopic surgery was performed to remove the tumors. After surgery, one patient (case 1) became pregnant twice within 29 months, and the other patient (case 2) did not become pregnant within 6 months postoperatively. These two cases suggest that laparoscopic management is not only useful in treating SSTO and complicating diseases, but it may also help to reduce unnecessary surgical injury to the ovary.

Endometrial stromal sarcoma arising in colorectal endometriosis: a case report and review of the literature. Case Rep Obstet Gynecol 2015; 2015:534273. [PMID: 25648532 PMCID: PMC4306220 DOI: 10.1155/2015/534273] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.4] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/27/2014] [Accepted: 12/23/2014] [Indexed: 02/05/2023] Open
Abstract
Extrauterine endometrial stromal sarcoma (ESS) arising in endometriosis is extremely rare, particularly in the colorectum. It should always be included in the differential diagnosis of primary tumors originating from gastrointestinal tract in females, given that preoperative endoscopical biopsy may reveal no specific changes. We reported a case of ESS arising in colorectal endometriosis and reviewed the previous 7 cases reported in the English literature. Our patient, who was unavailable for tumor resection and refused further adjuvant therapy, played a role in representing the natural history of low-grade extragenital ESS. This case was the only death from ESS arising in colorectal endometriosis.

Abstract
PURPOSE Mechanisms of immune dysregulation associated with advanced tumors are relatively well understood. Much less is known about the role of immune effectors against cancer precursor lesions. Endometrioid and clear-cell ovarian tumors partly derive from endometriosis, a commonly diagnosed chronic inflammatory disease. We performed here a comprehensive immune gene expression analysis of pelvic inflammation in endometriosis and endometriosis-associated ovarian cancer (EAOC). EXPERIMENTAL DESIGN RNA was extracted from 120 paraffin tissue blocks comprising of normal endometrium (n = 32), benign endometriosis (n = 30), atypical endometriosis (n = 15), and EAOC (n = 43). Serous tumors (n = 15) were included as nonendometriosis-associated controls. The immune microenvironment was profiled using Nanostring and the nCounter GX Human Immunology Kit, comprising probes for a total of 511 immune genes. RESULTS One third of the patients with endometriosis revealed a tumor-like inflammation profile, suggesting that cancer-like immune signatures may develop earlier, in patients classified as clinically benign. Gene expression analyses revealed the complement pathway as most prominently involved in both endometriosis and EAOC. Complement proteins are abundantly present in epithelial cells in both benign and malignant lesions. Mechanistic studies in ovarian surface epithelial cells from mice with conditional (Cre-loxP) mutations show intrinsic production of complement in epithelia and demonstrate an early link between Kras- and Pten-driven pathways and complement upregulation. Downregulation of complement in these cells interferes with cell proliferation. CONCLUSIONS These findings reveal new characteristics of inflammation in precursor lesions and point to previously unknown roles of complement in endometriosis and EAOC.
