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.

활액육종은 발생기원이 명확히 밝혀지지 않은 간엽조직 기원의 악성 종양으로 골수로의 침범을 보이는 경우는 종양의 5-15%로 비교적 드물다. 24세 남자 환자가 6-7개월 전부터 시작되어 최근 2-3주 사이에 악화된 우측 하퇴부의 동통과 종창을 주소로 내원하였다. 자기 공명 영상에서 우측 경골 하단부에 경골을 둘러싸는 모양의 1.5x5x9 cm 크기의 종괴가 있었는데 경골 피질의 파괴가 있었고 골수는 T1 강조영상에서 골수의 지방 신호가 감소하고 조영증강을 보이는 등 부분적인 골수의 침범의 소견을 동반하고 있었다. 수술로 절제된 조직은 조직학적 검사에서 이상성 (biphasic) 활액육종으로 진단받았고 병변이 경골을 침범하고 있었다.

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.

윤활막육종은 젊은 성인의 팔, 다리에 호발하는 악성종양이다. 흉막, 폐에 발생하는 윤활막육종은 드물게 보고되고 있으나, 본 증례처럼 흉벽에 생기면서 소아에 발생한 경우는 매우 드물다. 저자들은 소아의 흉벽에 발생한 윤활막종을 수술 치료한 경험을 보고하는 바이다. 현재 환아는 술 후 3년 동안 재발없이 잘 지내고 있는 중이다.

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.

흉통을 주소로 내원한 34세 남자 환자에서 흉부 컴퓨터 단층촬영상 좌측 흥부에 종괴와 흉막수가 발견되었다. 개흉술을 실시하여 벽측늑막에서 기원된 종괴를 제거하였으며 종괴는 저분화 활막육종으로 진단되었다. 벽측늑막에서 기원한 활막육종은 드문 질환으로 저자들은 이를 치험하였기에 보고하는 바이다.
