The results of histopathologic examination of the temporal bone of a 71-year-old woman with squamous cell carcinoma of the tonsil and ipsilateral facial palsy are presented. The right temporal bone was directly involved by metastatic spread of the primary lesion to the right upper cervical lymph nodes. Tumor cells had invaded the canal of the facial nerve, the chorda tympani nerve, and the stapedius muscle, as well as the air cells in the mastoid region. However, although tumor cells had infiltrated the facial canal to a considerable distance from the metastatic tumor mass, the facial nerve had not been infiltrated. Slight degeneration of the facial nerve, however, was observed and appeared to have been caused by compression by the tumor.
本文呈现了一位71岁患有扁桃体鳞状细胞癌并伴有同侧面神经麻痹的女性颞骨组织病理学检查结果。原发性病变通过转移扩散直接累及右侧颞骨至右上颈淋巴结。肿瘤细胞已侵入面神经管、鼓索神经、镫骨肌以及乳突区的气房。然而，尽管肿瘤细胞已浸润面神经管至距转移瘤块相当远的距离，但面神经并未被浸润。不过，观察到面神经有轻微变性，似乎是由肿瘤压迫所致。
