Parotid gland tumours are very heterogeneous, being benign in 80% of cases, and generally arising from epithelial cells. Nevertheless, a small group of non-epithelial tumours representing just 5% of all salivary gland neoplasms has also been reported, the most common of these being haemangioma, especially in children. However, lymphomas, neuromas, neurofibromas, lipomas and sarcomas can also be found. Synovial cell sarcoma is a high grade histological variety of sarcoma and is generally located near large joints and bursae of the lower extremities, such as knee, tendon sheaths and bursal structures. It is rarely found in the head and neck region due to its lack of synovioblastic tissue. Herewith, the case of a young female, affected by a synovial sarcoma of the left parotid gland, is presented and a review is made of the literature on this rare specific localization focusing on management and outcome.
腮腺肿瘤具有高度异质性，80%为良性肿瘤，通常来源于上皮细胞。然而，一小部分非上皮性肿瘤也有报道，仅占所有涎腺肿瘤的 5%，其中最常见的是血管瘤，尤其是在儿童中。然而，也可以发现淋巴瘤、神经瘤、神经纤维瘤、脂肪瘤和肉瘤。滑膜细胞肉瘤是一种高级别的肉瘤组织学类型，通常位于大关节和下肢的滑囊附近，如膝关节、肌腱鞘和滑囊结构。由于缺乏滑膜组织，它很少发生在头颈部。在此，报告了一例年轻女性左侧腮腺滑膜肉瘤，并对该罕见特定部位的文献进行了回顾，重点关注其治疗和预后。
