Abstract：
Carcinoma ex-pleomorphic adenoma (Ca ex-PA) comprises 0.5% of head and neck neoplasms. Transoral robotic surgery (TORS) is an approach being used to treat a variety of benign and malignant head and neck neoplasms. Recently, this technique has gained popularity as an alternative for parapharyngeal space (PPS) tumor resection. To our knowledge, this is the first case of Ca ex-PA managed successfully by TORS of the PPS.
Fifty-nine-year-old male with incidental mass in PPS, initial diagnosis of pleomorphic adenoma, who underwent transoral robotic resection. The histopathology diagnosis with minimally invasive Ca ex-PA findings and malignant component of high-grade epithelial/myoepithelial carcinoma and salivary duct carcinoma. Patient discharged on the fifth post-operative day without complications.
Based on our findings, TORS may be a safe procedure to remove selected Ca ex-PA from the PPS; however, further research is needed.

摘要：
多形性腺瘤（Caex-PA）占头颈部肿瘤的0.5％。经口机器人手术（TORS）是一种用于治疗各种良性和恶性头颈部肿瘤的方法。最近,作为咽旁间隙(PPS)肿瘤切除的替代方法,该技术已逐渐普及.据我们所知,这是第一例由PPS的TORS成功管理的Caex-PA。
59岁男性偶发PPS肿块，多形性腺瘤的初步诊断，接受经口机器人切除术的人。组织病理学诊断具有微创Caex-PA发现和高级别上皮/肌上皮癌和唾液腺导管癌的恶性成分。患者在术后第5天出院，无并发症。
根据我们的发现,TORS可能是从PPS中去除选定Caex-PA的安全程序；然而，需要进一步的研究。
