Chondrosarcomas of head and neck region are rare. Very few cases of chondrosarcomas arising in parotid gland have been reported and none with intracranial extension. We report a case of a female presenting with a parotid swelling and a mass in external auditory canal with extradural extension to posterior cranial fossa. With a preoperative fine needle aspiration diagnosis of pleomorphic adenoma, it was excised and the histopathology came out to be low-grade myxoid chondrosarcoma. She has not received any adjuvant chemoradiotherapy and there is no evidence of recurrence at months.
头颈部软骨肉瘤较为罕见。腮腺发生软骨肉瘤的病例报道极少，且尚无伴颅内侵犯的病例。我们报告一例女性患者，表现为腮腺肿大及外耳道肿物，并硬膜外扩展至后颅窝。术前细针穿刺诊断为多形性腺瘤，遂行切除，术后组织病理学检查结果为低级别黏液样软骨肉瘤。她未接受任何辅助放化疗，随访数月无复发迹象。
