Synovial sarcomas are rare soft tissue malignancies arising from tendons, tendon sheaths, and bursal structures. These tumors usually develop in the extremities of adolescents and young adults. Uncommonly, these tumors may arise in the head and neck approximately 9% of all synovial sarcomas. Most common sites of head and neck synovial sarcomas are hypopharynx and surrounding structures of paranasal sinuses. However, frontal bone without involving paranasal sinus is extremely rare. We report a case of biphasic synovial sarcoma of the frontal bone discuss the clinical and pathologic features of this case with the literature review.

Synovial sarcoma is usually found near large joints and bursae of the extremities. Only 10% of all synovial sarcomas occur in the head and neck. The most common site affected in the head and neck is the hypopharynx, and very rare in the infratemporal fossa. Treatment of synovial sarcoma of the head and neck is difficult and must have multimodality which consists of operation, radiation and chemotherapy. Prognosis is associated with completeness of resection. We reported a case of synovial sarcoma arising from the infratemporal fossa, the first case in Korea, with review of literature.

Synovial sarcoma is rare soft tissue tumor mesenchymal origin. Osseous involvement of synovial sarcoma is rare. A 24-year-old man presented with pain and swelling of the lower extremity. MRI of the lower extremity demonstrated a large mass encircling tibia with osseous involvement. Surgical excision of the mass was done and the mass was diagnosed as biphasic synovial sarcoma with bone marrow involvement. We also discuss the other imaging findings of synovial sarcoma on MRI.

Synovial sarcoma is a rare soft tissue tumor accounting for 5-10% of soft tissue sarcomas. Most arise in the extremities and trunk, and a small proportion occur in the abdominal wall, head and neck legion, and mediastinum. It manifests different phenotypic subtypes that render their cytologic evaluation challenging. Moreover, cytomorphologic description of the epithelial component of synovial sarcoma is rare in Korea. We report a case of biphasic synovial sarcoma on the right lower extremity in a 49-year-old woman diagnosed by fine needle aspiration cytology. The aspirate was moderately cellular and composed of a mixture of tissue fragments and dissociated cells with bland chromatin, inconspicuous nucleoli, and oval to spindle-shaped cytoplasm. Mitosis was rare. A monolayer sheet of epithelial component was seen. The cells in this monolayer sheet had more abundant distinct cytoplasm, round nuclei, and prominent micronucleoli. Histologic examination showed a biphasic pattern consisting of mostly sarcomatous stroma and a few small glandular areas at the periphery of the tumor.

Synovial sarcoma is a malignant soft-tissue tumor that most commonly occurs in the extremities of young adults. There have been several cases of synovial sarcomas of the pleural and lung reported, but synovial sarcoma arising from the chest wall in childhood is very rare. Here we report a case of synovial sarcoma arising from the chest wall in a 3 year-old female patient. The tumor was completely resected. No adjuvant therapy was given. The patient is well 3 years after the operation.

Synovial sarcoma us a rare malignant neoplasm of the soft tissue arising in the lower extremity, inguinal area, and upper arm. The majority occurs in patients between the age of 15 and 40 years. The histologic diagnosis is based on the classical biphasic type with the distinct epithelial and spindle cell components. We have recently encountered a case of metastatic synovial sarcoma of the lung diagnosed by fine needle aspiration cytology. A 34-year-old man was admitted because of a palpable mass on the antero-lateral side of the right tibia for 3 years. On admission, a well demarcated metastatic pulmonary nodule, measuring 5 cm in diameter, was also identified in the simple chest X-ray. Resection of the lower leg mass revealed typical histologic features of biphasic synovial sarcoma. Aspiration cytology of the pulmonary nodule revealed numerous clusters of spindle cells admixed with groups of epithelial cells. The epithelial cells had moderate-sized, round to oval shaped, and hyperchromatic nuclei. The cytoplasm was clear, but not distinctive. Interspersed tell elements were fibroblast-like spindle cells having elongated hyperchromatic nuclei.

Synovial sarcoma is a rare malignancy in the thoracic cavity, especially in the mediastinum. In this paper, a case of primary mediastinal synovial sarcoma is reported. A 34-year-old woman was hospitalized with dyspnea. Her chest X-ray and computed tomography (CT) showed a $16{\times}13{\times}11$ cm mass in her anterior mediastinal space. Surgical resection was performed but was incomplete. The pathological and immunohistochemical analysis confirmed the diagnosis of monophasic spindle cell synovial sarcoma. The patient underwent adjuvant radiotherapy for two months, but local recurrence and metastasis occurred in her pleural cavity. She eventually underwent chemotherapy for one year and died 18 months after her operation.

Synovial sarcoma is a malignant soft tissue tumor originated from the primitive mesencymal cell. It occurs primarily in the extremities, especially in the lower extremities. Primary pulmonary synovial sarcoma has been rarely reported in literatures. We experienced a case of intrapulmonary synovial sarcoma with brain metastasis which originated from the lung.

A 34-year-old male was admitted to our hospital complaining of chest pain. Chest computerized tomography showed pleural effusion and mass in left lower area. After open thoracotomy and mass removal originating from the parietal pleura were done. The mass was pathologically diagnosed as poorly differentiated synovial sarcoma. Synovial sarcoma of the pleura is rare. Herein we report a case of synovial sarcoma of the parietal pleura.

Synovial sarcoma is a malignant soft tissue tumor originated from primitive mesenchymal cell. It occurs primarily in the paraarticular regions, such as knee joint, ankle joint. We experienced a case of intrapulmonary synovial sarcoma which was originated from the lung.
