Abstract
The pathology of non-squamous carcinoma of the larynx is broad and there is a wide differential diagnosis. The most common presenting symptoms for laryngeal malignancies, both squamous and non-squamous, are hoarseness and dyspnea. Presentation with persistent or worsening symptoms and a submucosal lesion should raise suspicion for a non-squamous malignancy of the larynx. Accurate histology determines the most appropriate treatment and has an impact on prognosis.

Abstract
Primary laryngeal synovial sarcoma is an extremely rare tumor predominantly affecting young adults. There are currently no well-defined guidelines to direct investigation and management, and treatment is largely based on what is known for synovial sarcoma of the upper and lower limbs. This PROSPERO-registered study aims to review the diagnostic methods, treatment regimens, and survival outcomes for patients with synovial sarcoma of the larynx. A systematic search of databases Medline, Embase, SCOPUS, and Web of Science was undertaken in December 2017. The literature search identified 1031 potentially relevant studies, and after the deletion of duplicates and excluded papers, 98 full-text articles were screened. A total of 39 cases were reviewed from 32 studies in the data extraction. The average age at the time of laryngeal synovial sarcoma diagnosis was 32 years (range, 11-79 years). In all cases (n = 39), patients underwent wide surgical excision, with 20 patients requiring a partial or total laryngectomy. A total of 18 patients received adjuvant and 3 received neoadjuvant radiotherapy. Chemotherapy was used in 10 cases, with ifosfamide the most frequently used agent. There was considerable variability in the order and combinations of the abovementioned treatments. No clinicopathologic factors or treatment regimens were associated with improved overall survival or lower rate of recurrence. There is a paucity of literature and heterogeneity in clinical approaches to this highly aggressive sarcoma. Reporting of cases must be standardized and formal guidelines must be established to guide clinical management.

Abstract
We describe a rare case of primary pleural synovial sarcoma in a 27-year-old man with a 4-month history of dry cough and left-sided chest pain. A CT scan showed a large cystic mass in the left pleural cavity. The patient underwent two video-assisted thoracoscopic biopsies and the diagnosis of synovial sarcoma of the pleura was established. After neoadjuvant chemotherapy, which resulted in a partial response, the tumor was completely resected with extrapleural pneumonectomy. Pathological findings showed less than 5% of viable cancer and free surgical margins. The patient is clinically well 24 months after surgery, with no evidence of recurrent disease.

Abstract
Introduction: Synovial sarcoma is a rare mesenchymal malignant neoplasm that accounts for less than 10% of soft tissue sarcomas. About 95% of the sarcomas occur in the extremities. Primary synovial sarcomas of the spine are a rare tumor arising from the paravertebral regions, paraspinal muscles or epidural spaces.Purpose: To report an atypical radiological presentation of synovial sarcoma of the thoracic spine mimicking a nerve sheath tumor in an elderly adult and describe the management with review of the literature.Clinical presentation: A forty-six-year-old lady presented with clinical features of a thoracic intradural extramedullary cord compression at T7 level. She was Nurick grade 4 at presentation. MRI of the Thoracic spine with whole spine screening showed a contrast enhancing intradural extramedullary tumor at the T7-8 level; the tumor was exiting out through the left T7-8 neural foramina with foraminal widening. The possibility of a schwannoma was considered.Intervention: She underwent a T7-8 laminectomy and total excision of the tumor followed by posterior fusion. The biopsy was reported as synovial sarcoma. She subsequently underwent radiation and chemotherapy. She had marked improvement in her Neurological status and remained disease free at six months follow-up.Conclusion: Synovial sarcoma of the spine is a rare mesenchymal malignant neoplasm. One needs to consider Synovial sarcoma as one of the differential diagnosis of intradural tumors of the spine.

Abstract
INTRODUCTION Synovial sarcoma is a rare malignant tumor of the spine. This tumor may present as a painless mass of the spine or slowly enlarge, causing pain or neurologic deficits. As it is difficult to differentiate this lesion from other soft tissue tumors, synovial sarcoma requires histologic confirmation for definite diagnosis. Thus, the treatment strategy is often planned in the final step depending on the pathologic results. Despite its rare incidence, a few cases of primary or metastatic synovial sarcoma involving the spinal cord, foramen, vertebral body, or paraspinal muscles have been reported in the literature. MATERIALS AND METHODS We present the case of a 29-year-old man with a synovial sarcoma in the paraspinal muscle of the cervical spine. The patient was evaluated radiologically and histologically. Plain radiography, computed tomography, and magnetic resonance imaging were performed as part of the preoperative workup, and immunohistochemical and cytogenetic studies were additionally performed to identify the histologic features of the tumor. The patient underwent marginal resection followed by adjuvant radiation therapy. The patient has been followed up for 2 years. CONCLUSIONS This article highlights the features of synovial sarcoma of the spine via a comprehensive review. Synovial sarcoma of the spine is uncommon, but it is a challenging issue in both diagnostic and therapeutic aspects. The currently available evidence suggests the use of a multidisciplinary approach in the treatment of synovial sarcoma, which includes complete resection and radiation therapy.

Abstract
A 45-year-old lady presented to us with a large subcutaneous swelling on her left side of back of 1 year duration. Local examination revealed a 13×12 cm spherical swelling on the left lower paraspinal region. Magnetic resonance imaging of lumbosacral spine revealed a 13×12 cm mass having solid and cystic components with internal septations in the subcutaneous tissue of left posterior paraspinal area. The mass was hetrogenously hyperintense on T 2 weighted images suggestive of synovial sarcoma. Wide local excision of the lump was carried out followed by closure of the defect with a lateral intercostal artery based rotational flap. The histopathology of the excised tumor revealed synovial sarcoma that stained positive for cytokeratin and epithelial membrane antigen. This case highlights an unusually large subcutaneous synovial sarcoma present in para-spinal area.

Abstract
Synovial sarcomas commonly occur in the soft tissue of the extremities, while a primary occurrence in the mediastinum is quite rare. The current study reports the case of an 11-year-old male who presented with a neck mass, which computed tomography showed was due to a giant mediastinal mass involving the thyroid gland. The tumor was resected by thoracotomy and diagnosed as monophasic synovial sarcoma by histopathology. The patient received adjuvant combination chemotherapy and radiation therapy following surgery. At the 3-month follow-up, no local tumor recurrence was found. The present case report highlights the significance of recognizing the unusual presentation and clinical manifestation of synovial sarcoma to aid clinical management. Written informed consent was obtained from the patient’s family.

Abstract
Introduction. Synovial sarcomas (SS) are aggressive malignant soft tissue tumours that are thought to arise from pluripotent mesenchymal cells. Clinical Report. A 20-year-old male presented with an acute onset of respiratory stridor. Computer tomography scanning confirmed a mass arising from the left supraglottic larynx and an emergency tracheostomy was performed. A diagnosis of biphasic synovial sarcoma was formed. A total laryngectomy and left hemithyroidectomy was performed in conjunction with a left modified radical neck dissection. The patient received adjuvant chemotherapy followed by a course of radiotherapy and remains alive and disease free at 18 months after treatment. Discussion. Prognosis for patients with SS is related to primary tumour extent, grade, and size. The presence of the diagnostic translocation, t(X;18), is being targeted and hopefully will lead to the development of new therapeutics (Guadagnolo et al., 2007). Conclusion. Laryngeal SS remains a rare and poorly understood entity. A multidisciplinary approach to treatment is essential and long-term followup is imperative.

Abstract
We report five cases of primary synovial sarcomas arising in the parapharyngeal space. The patients were all men with a median age of 35 years (range 22 to 41 years). The tumors were non-encapsulated solid masses ranging from 2.0 to 6.6 cm in size. Histologically, three cases were biphasic subtype, and the other two cases were monophasic subtype. Immunohistochemically, the tumor cells were strongly positive for bcl-2 and CD99, partly positive for CK and EMA, and negative for CD117, CD34, SMA and desmin in all five cases. S-100 protein was detected in one case. The presence of an SYT-SSX1 and/or SYT-SSX2 gene fusion resulting from t(X;18) was demonstrated from paraffin blocks by reverse transcriptase polymerase chain reaction in five cases. All five patients received tumor radical excision and postoperative radiotherapy, and two patients with pulmonary metastasis received additional chemotherapy. Follow-up data revealed that two patients with tumor size <5 cm were alive without disease for 54 and 57 months, one patient with tumor size <5 cm was alive with pulmonary metastasis for 78 months, and two patients with tumor size >5 cm died of disease 26 and 37 months after the diagnosis, respectively. Primary parapharyngeal synovial sarcoma is a rare variant that occurs more frequently in males than females. Accurate diagnosis depends on morphologic and immunohistochemical examination and proper molecular analysis. The prognosis is relatively good in those patients whose tumor size is less than 5 cm.

Abstract
Background: Synovial sarcoma (SS) is a rare sarcoma with distinct morphologic and genetic features, which, despite its name, does not arise from synovium. While most SSs (>80%) arise in the deep soft tissue of the extremities, up to 5% of these tumors are encountered in the body axis including the spine, mediastinum, retroperitoneum, and head/neck regions. Reports of SS located within the spinal axis have been rare to date. Materials and Methods: We searched the medical records at our institution and found three patients who were diagnosed and treated for SSs involving the spine. We also performed an exhaustive literature search using PubMed to identify all reported cases in the literature. Results: In this study, we report on three SS cases involving the spine. All three cases involved the paraspinal muscles and spinal nerve roots, with one case having a significant leptomeningeal involvement. In two cases, “smaller operations” were performed first because the lesions were thought to be benign, however, when the final pathology identified them as SSs, more radical procedures were performed. Additionally, we identified 14 cases of SSs involving the spine published in the literature and all cases are reviewed here. Conclusions: Due to limited numbers of cases, spine SS long-term outcomes are hard to quantify. The currently accepted standard of treatment for SSs starts with wide surgical excision with negative margins followed by chemotherapy and radiation. We summarize the available literature on spinal SSs and review the current treatment options available for these tumors.

Abstract
OBJECTIVE To study the clinical and epidemiological characteristics of all adults patients as having synovial sarcoma in the Hospital Xeral-Calde (Lugo) between 2002 and 2006. PATIENTS AND METHOD We conducted a retrospective study of the case records of all adults patients diagnosed with synovial sarcoma from January 2002 through December 2006. Patients were considered to be adults if they were more than 18. In all cases a tissue-biopsy sample showing synovial sarcoma was required. The Hospital Xeral-Calde is the only referral center for a population of almost 250.000 people. RESULTS Four cases (3 women) met the classification criteria for this study. The mean age was 35 years old (range, 22-41). The most common presentation was a palpable mass (mean 6.7cm.) associated with pain in lower extremities. The mean delay for the diagnosis was 17 months, but in one case has been noted as long as 2.5 years. Unlike the neck synovial sarcoma case, a long delay in the diagnosis implied a major tumor size and a higher histologic grade. The mean follow-up was 25.5 months; one patient died 1.5 years after the diagnosis. CONCLUSIONS The overall annual incidence rate of synovial sarcoma in the Lugo region between January 2002 and 2006 for the population older than 18 years was a minimum estimate 0.32/10(5). Better physician awareness may contribute to the progressive increase in the recognition of this condition, especially in young people presenting with palpable mass. A long delay at the diagnosis implied a poor prognosis.

Abstract
STUDY DESIGN A case report is of a giant dumbbell-shaped synovial sarcoma of the thoracolumbar spine is presented. OBJECTIVE To report a case of a rare dumbbell-shaped tumor treated by multimodal approach. Surgical procedures, adjuvant treatment, and outcome were discussed. SUMMARY OF BACKGROUND DATA Synovial sarcomas of the spine are very rare tumors. Radical surgical resection is the goal, but is often not feasible. Dumbbell-shaped spinal synovial sarcoma with a giant extraspinal extension has not yet been reported. The rationale for 2-step surgical procedure and adjuvant therapy is discussed in light of the clinical picture, preoperative imaging and extension of the disease. METHODS A 32-year-old male patient presented with signs of quickly progressive paraparesis. A dumbbell-shaped tumor at the level Th12-L1 was found with a giant retroperitoneal extension. Tumor was nonradically excised in a 2-step operation: first through a dorsal approach with laminectomy and removal of the intraspinal extradural part, and later through a laparotomy with removal of the retroperitoneal part. Histologic examination revealed highly malignant synovial sarcoma. Patient was treated with chemotherapy and radiotherapy after surgery. RESULTS Patient was in remission and symptom free for 1 year after surgery; he then developed a local recurrence and died soon afterwards. CONCLUSION A good treatment result was achieved initially. A combined approach in cases like this is warranted, with as radical surgery as possible in order to avoid local recurrence, a common cause of treatment failure in sarcomas.

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.

Abstract
PURPOSE Peptide receptors are frequently overexpressed in human tumors, allowing receptor-targeted scintigraphic imaging and therapy with radiolabeled peptide analogues. Neuropeptide Y (NPY) receptors are new candidates for these applications, based on their high expression in specific cancers. Because NPY receptors are expressed in selected sarcoma cell lines and because novel treatment options are needed for sarcomas, this study assessed the NPY receptor in primary human sarcomas. EXPERIMENTAL DESIGN Tumor tissues of 88 cases, including Ewing sarcoma family of tumors (ESFT), synovial sarcomas, osteosarcomas, chondrosarcomas, liposarcomas, angiosarcomas, rhabdomyosarcomas, leiomyosarcomas, and desmoid tumors, were investigated for NPY receptor protein with in vitro receptor autoradiography using (125)I-labeled NPY receptor ligands and for NPY receptor mRNA expression with in situ hybridization. RESULTS ESFT expressed the NPY receptor subtype Y1 on tumor cells in remarkably high incidence (84%) and density (mean, 5,314 dpm/mg tissue). Likewise, synovial sarcomas expressed Y1 on tumor cells in high density (mean, 7,497 dpm/mg; incidence, 40%). The remaining tumors expressed NPY receptor subtypes Y1 or Y2 at lower levels. Moreover, many of the sarcomas showed Y1 expression on intratumoral blood vessels. In situ hybridization for Y1 mRNA confirmed the autoradiography results. CONCLUSIONS NPY receptors are novel molecular markers for human sarcomas. Y1 may inhibit growth of specific sarcomas, as previously shown in an in vivo mouse model of human ESFT. The high Y1 expression on tumor cells of ESFT and synovial sarcomas and on blood vessels in many other sarcomas represents an attractive basis for an in vivo tumor targeting.

Abstract
AIMS To examine the relevance of sentinel node biopsy in patients with synovial sarcoma. METHODS Between July 2004 and February 2007 11 consecutive patients with synovial sarcoma treated in our clinic underwent sentinel node biopsy after a preoperative lymphoscintigraphy. A handheld gamma-probe was used during the procedure to identify the sentinel nodes, which were then resected and submitted for histopathologic evaluation. RESULTS At least one sentinel node was identified in every patient. Of a total of 15 sentinels, one was positive and 14 negative. The patient with the positive sentinel underwent a regional lymph node dissection and remains disease-free 17 months later. One patient developed regional nodal metastases despite negative sentinel node biopsy and died 12 months after the procedure. No biopsy-associated complications were observed. CONCLUSIONS Sentinel node biopsy can be successfully and safely applied to patients with synovial sarcoma. Further prospective studies are required to determine the optimal treatment approach, the false negative rate and the prognostic significance of a positive sentinel node biopsy.

Abstract
Synovial cell sarcoma is an uncommon soft-tissue malignant tumour. These tumours have common radiological features with a variety of both benign and malignant lesions. However, there is a variety of imaging findings that can suggest a pre-biopsy diagnosis of synovial cell sarcoma. This pictorial review aims to describe the imaging features of synovial sarcoma in a series of cases with various age ranges and tumour locations. In addition, the pathology, staging, prognosis and management of synovial sarcoma is briefly discussed.

Abstract
Synovial sarcoma, a soft tissue sarcoma that develops in adults, is pathologically subclassified into monophasic spindle synovial sarcoma and biphasic synovial sarcoma with epithelial components. The molecular mechanism building the epithelial components in biphasic synovial sarcoma is totally unknown. Here we investigated claudins, critical molecules in the tight junction, in biphasic synovial sarcoma. Expression profiles of 21 claudins in 17 synovial sarcoma tumor samples, including 9 biphasic tumors, identified claudin4, claudin7, and claudin10 as biphasic tumor-related claudins, and immunohistochemical analyses demonstrated the localization of these claudins in the epithelial component in biphasic tumors, with claudin7 the most closely associated with the epithelial component. The mRNA expression and protein localization of claudin7 coincided with those of the ELF3, an epithelia-specific member of the Ets family of transcription factors. Luciferase reporter assays demonstrated that the presence of the Ets-binding site at -150 in the promoter region of the claudin7 gene was critical for the transcriptional activity, and gel shift and chromatin immunoprecipitation assays confirmed the binding of ELF3 to the Ets site at -150. Inhibition of ELF3 expression by small interfering RNA simultaneously down-regulated the mRNA expression of the claudin7 gene, and the introduction of ELF3 expression in claudin7-negative cell lines induced mRNA expression of the claudin7 gene. Therefore, the induction of claudin7 expression by ELF3 appears critical to the formation of the epithelial structures in biphasic synovial sarcoma.

Abstract
Pleuropulmonary synovial sarcoma (PPSS) is increasingly recognized as a subtype of sarcoma because of the recent identification of a distinctive chromosomal translocation specific to synovial sarcoma. Soft-tissue synovial sarcoma is far more common than PPSS and typically develops in para-articular locations of the extremities; affects young and middle-aged adults, with no difference in distribution between the sexes; and has well-documented radiologic manifestations. PPSS may arise in the chest wall, heart, mediastinum, pleura, or lung, and it shares patient demographics and several imaging features with its soft-tissue counterpart. Patients present with a cough, chest pain, or dyspnea. On chest radiographs, PPSS typically appears as a sharply marginated mass with uniform opacity, based either in the pleura or in the lung, and often accompanied by an ipsilateral pleural effusion. Computed tomographic images show a well-circumscribed heterogeneously enhanced lesion without associated involvement of bone and without calcifications (except in the case of a chest wall primary tumor). Magnetic resonance imaging provides superior demonstration of nodular soft tissue and multilocular fluid-filled internal components of PPSS, in addition to peripheral rim enhancement after the intravenous administration of a gadolinium-based contrast material such as gadopentetate dimeglumine. Current treatment consists of surgical resection followed by chemotherapy, radiation therapy, or both.
