进行腮腺恶性肿瘤手术时通常对其淋巴系统较为注意,但对面神经却不够重视。作者们在进行颞骨镜检时发现面神经可以成为腮腺癌的侵犯径路。病例报告:患者女性,52岁,12年前因右上颌窦癌行上颌骨摘除术。两年前右侧腮腺深部发生肿瘤,诊断为上颌窦癌复发,给与钴~(60)放射治疗,肿瘤消失,两年后死于肺炎。屍检时发现颞骨内面神经被囊腺癌侵犯,侵犯范围有垂直部及水平部,并经膝部到达内耳道。肿瘤细胞呈腺样结构,有粘液样物质。用高倍镜可以看到垂直部与 Parotid gland malignancy surgery is usually more attention to its lymphatic system, but the facial nerve is not enough attention. The authors found that the facial nerve can become a violation of the salivary gland cancer during the patella microscopy. Case report: A female patient, 52 years old, was treated with maxillary sinus cancer 12 years earlier. Two years ago, a tumor developed in the right parotid gland and was diagnosed as a recurrence of maxillary sinus cancer. He was treated with cobalt-60 radiation. The tumor disappeared and he died of pneumonia two years later. At the time of autopsy, it was found that the facial nerve of the sacrum was invaded by cystadenocarcinoma. The violation ranged from the vertical part to the horizontal part and reached the inner ear canal via the knee. Tumor cells are adenoid and have mucin-like substances. With high magnification you can see the vertical part and
