Abstract
Ewing sarcoma (ES) is a rare, aggressive malignancy that typically arises from bone and is seen more in adolescents and young adults. In contrast, extraskeletal Ewing sarcoma (EES) is more prevalent in adults and women [1,2]. There is no standard treatment for extraskeletal tumors, especially those in sensitive areas, such as the vagina, where resection may cause a large cosmetic or functional deformity. This case features a woman in her 20s who presented with painless vaginal bleeding and was found to have a 4 × 5 × 4-mm EES of the posterior vaginal wall. The presentation raised both reproductive and functional concerns, as the patient was young, sexually active and of childbearing age. The patient underwent treatment with radiation therapy and chemotherapy every 3 weeks. Given the lack of guidance and proclivity of EES to metastasize, it is paramount to proceed with standard-of-care treatment even if it is small and there is a lack of metastatic disease. For women with vaginal EES who are of childbearing age, brachytherapy rather than surgical resection may be a more favorable option when considering the location and the potential impact of vaginectomy.

Abstract
Ewing sarcoma is a rare poorly differentiated and highly malignant tumor primarily affecting the skeletal system. It most commonly presents during the first two decades of life and rarely might it be of extraskeletal origin. Majority of extraskeletal cases are reported in the paravertebral and lower limb, with very few cases reported in the cervical spine region. We report a case of extraskeletal Ewing sarcoma in a 42-year-old man who presented with a 1-year history of neck swelling associated with neck pain, diagnosed by computed tomography and magnetic resonance imaging scans, in conjunction with histological analysis. Very few cases of cervical EES presenting as dumbbell tumors have been documented in the literature especially in this age group.

Abstract
Extraskeletal Ewing sarcoma (EES) is a rare subtype in the Ewing sarcoma family of tumors (ESFT), which also includes Ewing sarcoma of bone (ESB) and, more recently, primitive neuroectodermal tumors. Although these tumors often have different manifestations, they are grouped on the basis of common genetic translocation and diagnosis from specific molecular and immunohistochemical features. While the large majority of ESFT cases occur in children and in bones, approximately 25% originate outside the skeleton as EES. Importantly, in the adult population these extraskeletal tumors are more common than ESB. Imaging findings of EES tumors are generally nonspecific, with some variation based on location and the tissues involved. A large tumor with central necrosis that does not cross the midline is typical. Despite often nonspecific findings, imaging plays an important role in the evaluation and management of ESFT, with MRI frequently the preferred imaging modality for primary tumor assessment and local staging. Chest CT and fluorine 18 fluorodeoxyglucose PET/CT are most sensitive for detecting lung and other distant or nodal metastases. Management often involves chemotherapy with local surgical excision, when possible. A multidisciplinary treatment approach should be used given the propensity for large tumor size and local invasion, which can make resection difficult. Despite limited data, outcomes are similar to those of other ESFT cases, with 5-year survival exceeding 80%. However, with metastatic disease, the long-term prognosis is poor. ©RSNA, 2022.

Is Chemotherapy Associated with Improved Overall Survival in Patients with Dedifferentiated Chondrosarcoma? A SEER Database Analysis. Clin Orthop Relat Res 2022; 480:748-758. [PMID: 34648466 PMCID: PMC8923599 DOI: 10.1097/corr.0000000000002011] [Citation(s) in RCA: 13] [Impact Index Per Article: 6.5] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/17/2020] [Accepted: 09/21/2021] [Indexed: 01/31/2023]
Abstract
BACKGROUND Dedifferentiated chondrosarcoma is a chondrosarcoma subtype associated with high rates of recurrence and a poor prognosis. Others have proposed treatment of dedifferentiated chondrosarcoma using osteosarcoma protocols, including perioperative chemotherapy. However, the rarity of this condition poses difficulties in undertaking single- institution studies of sufficient sample size. QUESTION/PURPOSE Is perioperative chemotherapy associated with improved overall survival in patients with dedifferentiated chondrosarcoma? METHODS We queried the Surveillance, Epidemiology, and End Results (SEER) 1973 to 2016 database for patients with a diagnosis of dedifferentiated chondrosarcoma (n = 308). As dedifferentiated chondrosarcoma was only classified as a distinct entity in SEER starting in 2000, only patients treated in 2000 and later were included. We excluded from our analyses those patients with distant disease at diagnosis, a primary site of disease other than bone or joints, and those who did not receive cancer-directed surgery. These criteria yielded 185 dedifferentiated chondrosarcoma patients for inclusion. We used Kaplan-Meier analyses and Cox proportional hazards models to assess the association of clinical, demographic, and treatment characteristics on overall survival (OS). RESULTS After controlling for confounding variables, including age, sex, tumor size, stage, grade, location, and radiation treatment status, and after adjusting for missing data, no overall survival benefit was associated with receipt of chemotherapy in patients with dedifferentiated chondrosarcoma (hazard ratio 0.75 [95% confidence interval 0.49 to 1.12]; p = 0.16). CONCLUSION Chemotherapy treatment of dedifferentiated chondrosarcoma was not associated with improved OS. These results must be viewed cautiously, given the limited granularity of information on chemotherapy treatment, the concerns regarding chemotherapy misclassification in SEER data, and the small sample of patients with dedifferentiated chondrosarcoma, all of which limit the power to detect a difference. Our findings are nevertheless consistent with those of prior reports in which no benefit of chemotherapy could be detected. Lack of clear benefit from perioperative chemotherapy in dedifferentiated chondrosarcoma argues that it should be used only after careful consideration, and ideally in the context of a clinical trial. LEVEL OF EVIDENCE Level III, therapeutic study.

Abstract
Extra-skeletal Ewing's sarcoma is among the rarest tumors in adults. The primary sites of the tumor dictates symptoms and signs, thus early treatments are compromised when more common tumors are lined up as differentials by the location. We present a case of a 35-year-old pregnant female who developed a renal Ewing sarcoma during pregnancy. A prior simple left kidney cyst in an ultrasound with no tumor signs was spotted. A month after her cesarean section she visited a doctor when she was sent and admitted for surgery with renal cell carcinoma as the primary diagnosis to the Firoozgar hospital. Histology confirmed the final diagnosis. To this end, she completed the standard chemotherapy for the renal Ewing sarcoma with pulmonary metastasis when she was re-evaluated for the general bone pain, diagnosed with multiple bone metastases, and ultimately approached her palliative care. She expired after 2 months. This study demonstrates: a gently progressive mass; palpable in late stages; introduced rise in mean corpuscular volume and lactate dehydrogenase with no drop in the hematocrit. In conclusion, any random parenchymal and/or cortical thickening in primary ultrasound and/or computed tomography demonstrating a cyst—whether displaying internal echo or not— with suggested signs should be furtherly evaluated.

Abstract
Ewing sarcoma (ES) and peripheral primitive neuroectodermal tumor are part of a spectrum of neoplastic diseases known as the ES family of tumors, which also includes extraosseous ES, peripheral primitive neuroectodermal tumor, malignant small-cell tumor of the thoracopulmonary region (Askin's tumor), and atypical ES. Although imaging features of these tumors have been previously described, extensive discussion about intra-abdominal manifestations is scarce in the literature. We present an imaging spectrum of these tumors in the abdomen and pelvis with particular attention to multimodality approach for staging and restaging.

Abstract
Ewing's sarcoma usually arises in the bones of children and adolescents. We herein report a 74-year-old man with Ewing's sarcoma in the adrenal gland. The diagnosis was confirmed by a genetic test, pathological studies, and several imaging studies. He already had multiple liver metastases when he was transferred to our hospital and died on the 37th day. The diagnosis was further confirmed by autopsy studies. Adrenal Ewing's sarcoma is very rare, and our patient was older than other reported cases. Ewing's sarcoma should be considered even in elderly patients with adrenal tumors.

Abstract
BACKGROUND Ewing sarcoma family of tumors (ESFT) of the kidney are exceedingly rare. Given the rarity of this neoplasm and the complexity associated with its management, information regarding treatment and outcome is warranted. MATERIALS AND METHODS We conducted a retrospective study of patients with ESFT of the kidney who were treated at MDACC between January 1, 2001 and January 1, 2011. Descriptive statistics were used. RESULTS Thirteen patients were identified (median age, 33 y; male:female 11:2). Common presenting symptoms were back pain, flank pain, and hematuria. Six patients had metastatic disease at presentation. Initial diagnostic biopsy was performed in 6 patients. Immunohistochemistry showed strong positivity for CD99 (mic2) and cytogenetic analysis demonstrated evidence of EWSR1 fusion gene in 8 cases. Nine patients underwent nephrectomy. Frequently used chemotherapy regimens consisted of vincristine, doxorubicin, and ifosfamide. Median overall survival was 17.2 months. Three patients were alive at the time of analysis, at 2, 7, and 11 years from diagnosis (the latter without evidence of disease). CONCLUSIONS Renal ESFT carry a guarded prognosis with limited response to therapy and short median overall survival. For patients with metastatic disease, diagnostic biopsy and sarcoma-based chemotherapy regimens are recommended as upfront therapeutic strategy. The role of nephrectomy in the metastatic setting is unclear. Future studies with novel therapies are needed.

Abstract
Rhabdomyosarcomas are malignant neoplasms with striated muscle differentiation. This is the most common type of soft-tissue sarcoma in children, but occurs rarely in adults. Its occurrence in liver is infrequent. We report a case of primary hepatic embryonal rhabdomyosarcoma in a 67-year-old man. The tumour was occupying the left lobe of the liver with large component of lesion seen bulging in left subhepatic space indenting over the stomach, compressing the pancreas and gall bladder. A percutaneous biopsy was performed which revealed embryonal rhabdomyosarcoma. He underwent a successful left lobectomy with complete resection of the tumour, followed by adjuvant chemotherapy. The patient is free of disease at 24 months of follow-up. Hence, an early diagnosis, prompt surgical resection with negative resection margin along with adjuvant chemotherapy can provide complete remission. This case is extremely rare both due to the age of the patient at presentation and location of the tumour.

Abstract
AIM OF THE STUDY Aim of the study was to investigate the demographics of Ewing sarcoma family of tumours (ESTF) patients, treatment alternatives, clinical outcomes, and prognostic factors for survival. MATERIAL AND METHODS We retrospectively reviewed 39 patients with ESFT who were admitted to our institute between September 2008 and September 2012. RESULTS The patients included 32 (82.1%) males and seven (17.9%) females of median age 24 (range, 18-66) years. Among the 27 patients with a primary osseous localization, 17 (43.5%) had a central axis localization. Fifteen patients (38.5%) had metastases at the time of diagnosis. Patients were followed up for a median period of 18 (range, 2-134) months. The median event-free survival (EFS) was 23 (range, 1-64) months, and the 1- and 4-year EFS were 60% and 48%, respectively. The median overall survival (OS) was 91 (range, 1-188) months, and the 1- and 4-year OS were 78% and 54%, respectively. Gender, age, primary tumor site, and local treatment modalities, either alone or in combination, did not have a significant effect on OS (p = 0.210, p = 0.617, p = 0.644, and p = 0.417, respectively). In contrast, osseous site of peripheral localization, limited stage, and metastasis to the bone significantly affected OS (p = 0.015, p < 0.001, and p = 0.042, respectively). CONCLUSIONS ESFTs are aggressive tumors with a high rate of relapse and metastatic potential. Patients with peripheral bone involvement and limited stage had a good prognosis. Appropriate surgical resection, radiotherapy, and aggressive chemotherapy regimens are recommended.

Abstract
OBJECTIVES We aimed to determine the prognostic factors that influence the outcome of adult patients who have disease relapse after treatment for localized Ewing sarcoma. METHODS We retrospectively searched for the records of patients aged 18 years and older with localized Ewing sarcoma at Mayo Clinic, Rochester, Minnesota, from 1977 to 2007, who had disease relapse after initial treatment. Patient records were reviewed to analyze factors affecting survival. RESULTS A total of 49 patients were identified. The 5-year postrelapse survival rate was 30%. Significant factors affecting the 5-year postrelapse survival rate included site of initial relapse (local vs. distant, 55% vs. 22%, P=0.045); time to relapse (<2 vs. ≥ 2 y from original diagnosis, 12% vs. 50%, P=0.003); and second remission with complete surgical resection versus definitive radiotherapy to the recurrent disease (48% vs. 13%, P<0.001). None of these factors were significant on multivariate modeling. CONCLUSIONS Adult patients with Ewing sarcoma who have disease relapse after primary treatment of localized disease will continue to have recurrences regardless of the modality of salvage therapy. Those that have relapse locally or >2 years after the initial diagnosis and are able to achieve a second remission with definitive surgical or radiation therapy have better survival than those who have disease relapse distantly or before the 2-year time point.

Abstract
OBJECTIVE The purpose of this study was to compare the diagnostic performance of (18)F-FDG PET/CT and conventional imaging for staging and follow-up of pediatric osteosarcoma and skeletal Ewing sarcoma. MATERIALS AND METHODS We calculated sensitivity, specificity, and accuracy of PET/CT and conventional imaging (CT, MRI, bone scanning) for sites of disease and number of lesions. Diagnostic benefit, defined as better characterization of lesions, was evaluated on a per-scan basis, comparing PET/CT and conventional imaging. RESULTS A total of 412 lesions were characterized by imaging in 64 patients (20, osteosarcoma; 44, Ewing sarcoma). For osteosarcoma patients PET/CT was available only at follow-up, where it proved more accurate than conventional imaging for the detection of bone lesions (accuracy, 95% vs 67% for CT and 86% for MRI) and complementary to CT in evaluating lung nodules (sensitivity, 84% vs 94%; specificity, 79% vs 71%) with diagnostic benefit in 18% of examinations. In patients with Ewing sarcoma, PET/CT tended to perform better during follow-up than at initial staging (accuracy, 85% vs 69%). For lung findings, PET/CT was more specific than CT but was less sensitive. The diagnostic benefit of PET/CT was greater at staging (28%) than during followup (9%). On a per-patient basis, PET/CT provided diagnostic benefit in 21 of 44 patients with Ewing sarcoma and nine of 20 patients with osteosarcoma at least once during clinical management. CONCLUSION FDG PET/CT provides diagnostic benefit in Ewing sarcoma and osteosarcoma, with the exception of small lung nodules. Prospective studies are needed to define the best imaging algorithm and combination of tests in the staging and follow-up of patients with pediatric bone sarcoma.

Abstract
BACKGROUND AND PURPOSE To evaluate local control and survival outcomes in adults with Ewing sarcoma (ES) treated with radiotherapy (RT). MATERIAL AND METHODS Retrospective review of all 109 patients age ⩾18 treated for ES with RT to the primary site at Memorial Sloan Kettering Cancer Center between 1990 and 2011. RT was used as the definitive local control modality in 44% of patients, preoperatively for 6%, and postoperatively for 50%. RESULTS Median age at diagnosis was 27years (range, 18-67). The 5-year local failure (LF) was 18%. Differences in LF were not identified when evaluated by modality of local control (RT versus combined surgery and RT), RT dose, fractionation, and RT technique. However, margin status at time of resection significantly predicted LF. The 5-year event-free survival and overall survival rates were 44% and 66% for patients with localized disease, compared with 16% and 26% for metastatic disease (p=0.0005 and 0.0002). Tumor size, histopathologic response to chemotherapy, and treatment on or according to a protocol were also significantly associated with survival. CONCLUSIONS This series of adults treated with modern chemotherapy and RT had prognostic factors and outcomes similar to adolescents with ES. All adults with ES should be treated with an aggressive, multidisciplinary approach.

Abstract
Rhabdomyosarcoma (RMS), a malignant tumor of mesenchymal origin, is the third most common extracranial malignant solid tumor in children and adolescents. However, in adults, RMS represents <1% of all solid tumor malignancies. The embryonal and alveolar histologic variants are more commonly seen in pediatric patients, while the pleomorphic variant is rare in children and seen more often in adults. Advances in the research of the embryonal and alveolar variants have improved our understanding of certain genes and biologic pathways that are involved in RMS, but much less is known for the other variants. Multimodality therapy that includes surgery and chemotherapy with or without radiation therapy is the mainstay of treatment for RMS. Improvements in the risk stratification of the pediatric patients based on presurgical (primary tumor site, tumor size, regional lymph node involvement, presence of metastasis) and postsurgical parameters (completeness of resection or presence of residual disease or metastasis) has allowed for the treatment assignment of patients in different studies and therapeutic trials, leading to increases in 5-year survival from 25%–70% over the past 40 years. However, for adult patients, in great part due to rarity of the disease and the lack of consensus on optimal treatment, clinical outcome is still poor. Many factors have been implicated for the differing outcomes between pediatric RMS versus adult RMS, such as the lack of standardized treatment protocols for adult RMS patients and the increased prevalence of advanced presentations. Now that there are increased numbers of survivors, we can appreciate the sequelae from therapy in these patients, such as bone growth abnormalities, endocrinopathies, and infertility. Improvements in risk stratification have led to clinical trials using lower doses of chemotherapy or radiation therapy with the intention of decreasing the incidence of side effects without compromising survival outcome.

Abstract
OBJECTIVE To describe the multimodality imaging features, metastatic pattern and clinical outcome in adult extraskeletal Ewing sarcoma (EES). METHODS In this institutional review board-approved, health insurance portability and accountability act-compliant retrospective study, we included 26 patients (17 females and 9 males; mean age, 36 years; range, 18-85 years) with pathologically confirmed EES seen at our institute between 1999 and 2011, who had imaging of primary tumour. Imaging of primary tumour in all 26 patients and follow-up imaging in 23 was reviewed by two radiologists in consensus. Clinical data were extracted from electronic medical records. RESULTS The most common primary sites were the torso (n = 13), extremities (n = 10) and head and neck (HN) region (n = 3). The mean tumour size was 9 cm (range, 3-22 cm); tumours of the torso were larger than those of other areas (p > 0.05). Compared with the skeletal muscle, tumours were isodense on CT (21/21), hypointense (n = 5) to isointense (n = 14) on T1 weighted image, hyperintense on T2 weighted image (19/19) and were fluorine-18 fludeoxyglucose ((18)F-FDG)-avid [10/10; mean maximum standardized uptake value of 7 (range, 3-11)]. Necrosis (15/26), haemorrhage (5/26) and adjacent organ invasion (14/26) were present without calcification. Median follow-up was 16 months. 5 patients had local recurrence (torso, 3; extremity, 1; and HN, 1). Metastases developed in 11 patients (torso, 7; extremities, 3; and HN, 1; p > 0.05); 8 at presentation, most commonly to lung (9/11), peritoneum (4/11), muscles (4/11) and lymph nodes (4/11). Nine patients (torso, 7; extremity, 1; and HN, 1) died (10 months median survival) (p > 0.05). CONCLUSION Adult EESs are large tumours, which frequently invade adjacent organs and metastasize to the lung. EESs of the torso are larger, have more frequent metastases and poorer outcomes. ADVANCES IN KNOWLEDGE Adult EESs of the torso have poor outcomes compared with other EESs.

Abstract
Extraosseous Ewing's sarcoma/peripheral neuroectodermal tumors (ES/PNETs) are rare neoplasms that account for approximately 10%-15% of soft tissue sarcomas in children and 5% of soft tissue sarcomas in adults. Primary spinal, extraosseous, intradural ES/PNETs are even less common. The diagnosis of ES/PNET is extremely challenging, because the tumor can have a nonspecific radiologic appearance, and the histologic features are shared by many other "small round cell tumors." Thus, ES/PNET should be included in the radiologic and pathologic differential diagnosis, even in older patients and in unusual tumor sites. We report two cases of spinal, extraosseous, intradural ES/PNETs in adults who presented with back pain. Magnetic resonance imaging revealed contrast enhancing, intradural lesions in the area of the conus medullaris. The tumor in Case 1 was partially intramedullary, while the tumor in Case 2 was exclusively extramedullary. In both cases, the radiologic and intraoperative surgical impression favored ependymoma. The diagnosis of ES/PNET was established in both cases by histopathologic, immunohistochemical, and molecular analysis.

Abstract
Sarcoma are about 1% of cancers. Within that 1% are widely varied tumors now divided into types and subtypes. Sarcoma occur in patients of all ages with frequency spread evenly over the human age range. Although the specific cell of origin of many sarcoma remains unclear, sarcoma are all tumors of mesenchymal origin. The mesenchymal stem cell, a pluripotent cell, which gives rise to varied differentiated cells including osteocytes, adipocytes, chondrocytes, muscle cells, fibroblasts, neural cells and stromal cells, is the most likely ultimate cell of origin for sarcoma. When mesenchymal stem cell genetics go awry and malignant transformation occurs sarcoma including osteosarcoma, Ewing's sarcoma, chondrosarcoma, rhabdomyosarcoma, synovial sarcoma fibrosarcoma, liposarcoma and many others can initiate. Our knowledge of sarcoma genetics is increasing rapidly. Two general groups, sarcoma arising from chromosomal translocations and sarcoma with very complex genetics, can be identified. Genes that are frequently mutated in sarcoma include TP53, NF1, PIK3CA, HDAC1, IDH1 and 2, KDR, KIT and MED12. Genes that are frequently amplified in sarcoma include CDK4, YEATS4, HMGA2, MDM2, JUN, DNM3, FLT4, MYCN, MAP3K5, GLI1 and the microRNAs miR-214 and miR-199a2. Genes that are upregulated in sarcoma include MUC4, CD24, FOXL1, ANGPTL2, HIF1α, MDK, cMET, TIMP-2, PRL, PCSK1, IGFR-1, TIE1, KDR, TEK, FLT1 and several microRNAs. While some alterations occur in specific subtypes of sarcoma, others cross several sarcoma types. Discovering and developing new therapeutic approaches for these relentless diseases is critical. The detailed knowledge of sarcoma genetics may allow development of sarcoma subtype-targeted therapeutics.

Abstract
OBJECTIVE Though classically thought of as an osseous-based sarcoma of children and adolescents, it is important to recognize that approximately 20% of all cases of Ewing sarcoma family of tumors (ESFT) occur in patients older than 18 years, often with extraskeletal disease. Understanding the specific imaging features, manners of presentation, and patterns of behavior of ESFT is therefore important in all settings. CONCLUSION This article presents the imaging findings of ESFT in the adult, with specific attention to extraskeletal manifestations.

Abstract
Mycetoma, also commonly referred to as Madura foot, is statistically rare in the United States. However, it is endemic to other parts of the world. It is a pseudotumor characterized by a triad of tumefaction, draining sinuses, and grains. Two types exist, with each caused by different groups of organisms that require different treatment approaches. Therefore, the exact diagnosis and culture of the organism is vital to successful treatment outcomes. Synovial sarcoma, in contrast, is a malignancy much more commonly seen in the United States. It is characterized by a well-circumscribed, often palpable, mass that is usually well delineated on magnetic resonance imaging. It has characteristic histologic and genetic features that help distinguish it from other soft tissue masses. We present a case of a soft tissue mass diagnosed in the United States. The patient had several clinical and radiographic features of synovial sarcoma but the histologic outcome was mycetoma. The case is followed by a review of the published data.

Abstract
OBJECTIVE Pediatric-type sarcomas such as Ewing's sarcoma (EWS)/primitive neuroectodermal tumor family and rhabdomyosarcoma are relatively uncommon in adult patients. Optimal treatment strategies for this population and prognosis in adult patients compared with pediatric patients remain controversial. METHODS We retrospectively reviewed pediatric-type sarcoma patients older than 15 years at a single institution. RESULTS A total of 84 consecutive patients between 1995 and 2009 were identified at the Samsung Medical Center, Seoul, Korea. Median age was 30 years with a range of 15-74 years. Forty-seven patients (56.0%) were diagnosed with Ewing's sarcoma/primitive neuroectodermal tumor family, 34 (40.5%) with rhabdomyosarcoma and 3 (3.6%) with desmoplastic round-cell tumor. Median follow-up duration was 5.9 years. Median overall survival for all patients was 33.1 months (95% CI 13.5-52.7) and median event-free survival for all patients was 14.4 months (95% CI 5.9-22.9 months). Multivariate analysis revealed that localized disease was a significant independent prognostic factor for longer overall survival (hazard ratio 0.30, 95% CI 0.14-0.66, p = 0.003), and favorable primary tumor sites were associated with longer event-free survival (hazard ratio 0.33, 95% CI 0.11-0.98, p = 0.045). CONCLUSION We identified the prognostic variables which may facilitate risk-adapted therapies for this rare adult sarcoma group, which should be further investigated.

Abstract
PURPOSE The current treatments of and new therapeutic options for the management of Ewing's sarcoma (ES) are reviewed. SUMMARY ES is the second most common primary bone malignancy in pediatric patients and is numbered among the cancers that result in the greatest risk of mortality and morbidity in children and young adults. Much progress has been made in the treatment of ES since the disease was first described in the 1920s. With current multimodality treatment including chemotherapy, radiation, and surgery, patients with localized disease have a long-term survival rate of approximately 50%. Survival rates for patients with metastatic disease or those with early relapse remain poor. New combinations of cytotoxic agents such as cyclophosphamide, topotecan, irinotecan, and temozolomide have shown efficacy and tolerability in patients with relapsed or refractory disease. To date, the role of high-dose chemotherapy supported by stem cell rescue as a consolidation therapy for high-risk ES tumors has yet to be conclusively determined. Much effort is being invested in treating cancer with targeted therapies, and the EWS-ETS fusion gene would likely provide an important tumor-specific target. Tyrosine kinases (TKs) are overexpressed in human sarcoma tumors, and cell lines may serve as potential targets for new therapies. One TK receptor that is a promising therapeutic target is insulinlike growth factor-1 receptor. CONCLUSION Treatments for ES include surgery, radiation, and cytotoxic regimens, many of which include vincristine. Treatment for recurrent ES has included topotecan, cyclophosphamide, temozolomide, and irinotecan. Angiogenesis inhibitors, TK inhibitors, and bisphosphonates have also been studied.

Abstract
Sclerosing spindle cell rhabdomyosarcoma (SSRMS) is a newly recognized entity in adults. The authors report a new case of SSRMS in a 31-year-old woman who presented with a large right leg mass. Biopsy revealed a malignant spindle cell neoplasm with focal sclerotic areas. A diagnosis of monophasic synovial sarcoma was favored initially. The tumor cells in the resection specimen were positive for myosin, myogenin, and MyoD1. Fluorescence in situ hybridization performed on the resection specimen showed no evidence of SYT gene rearrangement in the neoplastic cells, ruling out monophasic synovial sarcoma. A diagnosis of SSRMS was established. The patient succumbed to widely metastatic disease 16 months after initial diagnosis. This case highlights the utility of skeletal muscle markers and cytogenetic testing in distinguishing SSRMS from its mimic, monophasic synovial sarcoma. It is hoped that this case will expand the literature on adult SSRMS and help clinicians and pathologists better understand this newly described entity.
