Synovial sarcomas are aggressive soft-tissue tumors with the propensity for metastases at presentation or later course of disease. The most common site of metastases is lung, followed by lymph node and bone. It rarely metastasizes to the liver and to the brain. Breast metastases from extramammary tissue are extremely rare, more so from synovial sarcoma. F-fluorodeoxyglucose positron emission tomography-computed tomography (FDG PET/CT) plays a very important role in diagnosing occult metastasis in sarcomas. Histopathological diagnosis and translocation studies are important to confirm the diagnosis. We present a case of synovial sarcoma who underwent FDG PET/CT which showed occult metastasis to the breast.
滑膜肉瘤是侵袭性软组织肿瘤，在疾病初发或病程后期有转移倾向。最常见的转移部位是肺，其次是淋巴结和骨。它很少转移至肝脏和脑。乳腺外组织转移至乳腺极为罕见，滑膜肉瘤转移至乳腺更是罕见。F-氟脱氧葡萄糖正电子发射断层扫描-计算机断层扫描（FDG PET/CT）在诊断肉瘤隐匿性转移中发挥着非常重要的作用。组织病理学诊断和易位研究对于确诊很重要。我们报告一例滑膜肉瘤患者，其接受FDG PET/CT检查显示乳腺存在隐匿性转移。
