本文报告1例颞骨转移性纤维肉瘤的组织病理学检查。此肿瘤的原发部位是后颈部区域。患者最初的主要症状是左侧面神经麻痹。虽然病人接受了枕下后颅骨切除术，放疗和化疗，她最终死于多发性转移。颞骨组织学检查显示肿瘤广泛侵犯外耳道、中耳腔、中耳肌、鼓膜、乳突腔、岩尖、面神经和前庭神经（左耳）的上级分支（远段）。茎乳孔经面神经管至前庭神经上级支的途径可能是肿瘤侵犯的途径之一。
A case of metastatic fibrosarcoma of the temporal bone was studied histopathologically. The primary site of this tumor was the posterior neck region. The initial major symptom of the patient was a left facial nerve paralysis. Although the patient underwent a suboccipital posterior craniectomy, radio-, and chemotherapy, she eventually died from multiple metastases. Histological examination of the temporal bones showed an extensive tumor invasion in the external auditory canal, middle ear cavity, middle ear muscle, tympanic membrane, mastoid cavity, petrous apex, facial nerve, and superior division (distal segment) of the vestibular nerve (left ear). The route from the stylomastoid foramen to the superior division of the vestibular nerve via the facial nerve canal could be one of the possible passages of tumor invasion.
