Abstract：
Synovial sarcomas are uncommon and highly aggressive sarcomas. Typically, they start in the soft tissues of the extremities, although they may develop in the head and neck region in rare cases. When they do, they usually present with localized symptoms in the affected area. Our patient is a 20-year-old man without a medical history who complained of a three-month history of submental swelling of the left side with a non-tender, palpable 5 cm mass. Initially believed to be a plunging ranula, the patient underwent transoral excision of the left submandibular soft tissue mass in the neck by the ear, nose, and throat (ENT) specialist. The pathological analysis of the mass confirmed the presence of a poorly differentiated synovial sarcoma. A postoperative neck imaging was performed, which showed a significant decrease in mass size compared to the previous imaging; however, the mass was still present. This is one of the few described cases of a poorly differentiated synovial sarcoma located on the floor of the mouth. Therefore, it highlights the importance of considering it as a possible differential diagnosis of head and neck pathologies.
摘要：
滑膜肉瘤是一种罕见且高度侵袭性的肉瘤。通常,它们从四肢的软组织开始，尽管在极少数情况下它们可能在头颈部发展。当他们这样做的时候，他们通常在受影响的地区出现局部症状。我们的患者是一名20岁的男性，没有病史，他抱怨有三个月的左侧精神下肿胀，可触及的5厘米质量。最初被认为是一个暴跌的牧场，患者接受了经口切除颈部左耳下颌下软组织肿块，鼻子,和喉部（ENT）专家。肿块的病理分析证实存在低分化的滑膜肉瘤。进行了术后颈部成像，与以前的成像相比，它显示出质量大小的显著减少；然而，弥撒仍然存在。这是少数描述的位于口底的低分化滑膜肉瘤病例之一。因此,它强调了将其视为头颈部病变的可能鉴别诊断的重要性。
