Synovial sarcoma is a well-recognized malignant mesenchymal neoplasm. Primary retroperitoneal synovial sarcoma is extremely rare and has poor prognosis. There are sparse reports in the literature on the secretory synovial sarcomas. In this report, we present the case of a patient with retroperitoneal synovial sarcoma who presented with recurrent attacks of hypoglycaemia.

BACKGROUND Synovial sarcoma is a malignant tumor of soft tissue that is rarely found in the head and neck. Even less common are metastasis within the head and neck. METHODS We describe a case of a delayed metastatic synovial sarcoma to the scalp. A man who had been diagnosed and treated 16 years previously for monophasic synovial sarcoma of the groin, presented with a new scalp lesion confirm...

Sarcomas are rare tumors account for about 1% of cancers in adult. Soft tissue sarcomas are the most common one. Synovial sarcoma's incident is about 10% of all sarcomas and most commonly rise from para-articular regions in young adults. Based on our knowledge there have been only two reports of thyroid synovial sarcoma in medical literature. We report a 44-year old woman presented with a rapid...

Synovial sarcomas are generally deep-seated tumors that most often occur in the proximity of large joints of adolescents and young adults. We describe two cases of primary renal synovial sarcoma that were treated successfully by radical nephrectomy. Synovial sarcoma originating from the kidney is extremely rare and the histogenesis is uncertain. Surgical resection and ifosfamide based chemother...

Although synovial cell sarcoma is reported to be the most common neoplasm of the canine synovium, this retrospective study of 35 canine synovial tumors found that the majority were of histiocytic origin. Five (14.3%) synovial cell sarcomas were identified by positive immunohistochemical staining with antibodies to cytokeratin. Eighteen (51.4%) histiocytic sarcomas were identified by cell morpho...

UNLABELLED Synovial sarcoma is an aggressive soft-tissue malignancy of children and young adults, with no effective systemic therapies. Its specific oncogene, SYT-SSX (SS18-SSX), drives sarcoma initiation and development. The exact mechanism of SYT-SSX oncogenic function remains unknown. In an SYT-SSX2 transgenic model, we show that a constitutive Wnt/β-catenin signal is aberrantly activated by...

Synovial sarcoma is a malignant soft tissue tumor that most commonly occurs in the extremities of young and middle-aged adults, in the vicinity of large joints. Although synovial sarcoma is frequently associated with joints, it may arise in unexpected sites, such as the mediastinum, heart, lung, pleura, or chest wall. Primary synovial sarcoma of the pleura is rare. To date, nearly 36 cases of p...

Synovial sarcoma develops as a primary neoplasm of soft tissues, particularly of the extremities, but it has been also reported in a large variety of sites. This tumor is not derived from “synovium”, but from immature mesenchymal elements. Synovial sarcoma accounts for approximately 8-14% of soft tissue sarcomas (1, 2). Although metastases to the lung and/or pleural cavity are common events in ...

BACKGROUND Synovial sarcoma represents one of the most frequent malignant tumours of soft tissues. Its prognosis is poor because of chemoresistance and high metastatic potential. Improvement of synovial sarcoma outcome requires well-characterized animal models in which to evaluate novel therapeutic options. The aim of this study was to establish a reproducible synovial sarcoma model in athymic ...

INTRODUCTION Contrary to its name, synovial sarcoma does not arise from the synovial membrane but from multipotent stem cells and can present in any part of the body. Very few cases of vulval synovial sarcoma have been reported in the literature; we report on such a presentation. These tumors can present as painless lumps, which must be completely excised to give the best prognosis. Therefore t...
