原发性腺癌是一种罕见的肿瘤，发生于中桨和颞骨，最常见的症状是听力丧失、耳痛和面瘫。一位27岁男性的耳镜检查发现耳道有脓性分泌物，弥漫性水肿，以及右鼓膜肥大。患者出现III级（House-Brachman）面神经麻痹和右侧传导性听力损失，有耳分泌物6个月、耳痛和面神经无力2天的病史。颞骨电脑断层显示一个不透明物充满鼓室、窦和入口。鼓室切开术显示中耳粘膜弥漫性水肿，乳突切除术期间遇到肉芽组织填充窦和窦周细胞，并在卵圆窗水平侵蚀输卵管。在组织病理学检查发现乳头状腺癌后，进行了颞骨次全切除术，面神经节段切除术，面神经与舌下神经端端吻合术。组织病理学检查的重要性，在所有情况下，慢性中耳炎肉芽组织强调。
Primary adenocarcinoma is a rare tumor of the middle oar and temporal bone; its most frequent symptoms are hearing loss, otalgia, and facial paralysis. Otoscopic examination of a 27-year-old man revealed purulent discharge in the ear canal, diffuse edema, and hypertrophy of the right tympanic membrane. He presented with a grade III (House-Brachman) facial paralysis and right conductive hearing loss with a history of aural discharge for 6 months, otalgia, and facial weakness for 2 days. Computed tomography of the temporal bone showed an opacity filling the tympanic cavity, antrum, and aditus. Tympanotomy revealed diffuse edema of the middle ear mucosa, and granulation tissue was encountered during mastoidectomy filling the antrum and periantral cells and eroding the fallopian canal at the lever of the oval window. After the histopathological examination revealed papillary adenocarcinoma, a subtotal temporal bone resection, facial nerve segmenter resection, and end-to-end anastomosis of the facial with the hypoglossal nerves were performed. The importance of histopathological examination in all cases of chronic otitis media with granulation tissue is stressed.
