手术切除咽部巨大多形性腺瘤1例

A case report of surgical resection of giant pharyngeal pleomorphic adenoma and literature review

1病例报告患者,女,63岁,以睡眠打鼾4年,呼吸不畅3个月为主诉来我院就诊。不痛,进食吞咽有阻碍感,无痰中带血。专科检查：口咽黏膜慢性充血,右侧软腭明显有一隆起,约鸭蛋大小,堵塞口咽,表面可见血管扩张,按压无痛,触之较硬,悬雍垂尚居中。间接喉镜检查：会厌无充血,双声带运动正常。MRI显示：口咽部巨大肿物,考虑良性肿瘤（血管瘤可能性大）（图1）。

Summary Pleomorphic adenoma （PA） is a rare benign tumor in the pharynx. We presented a case with a huge PA in the pharynx. MRI displayed oropharyngeal mass, considering benign tumor. Preoperative fine-needle aspiration and cytology biopsy were important to confirm the diagnosis of PA preliminary. Extracapsular complete dissection for PA was performed under general anesthesia with tracheotomy subsequently. Postoperative his- topathological examination confirmed the diagnosis of PA. The patient was discharged a week after operation and no recurrence was found in the following 8 months.
