小儿原发中耳恶性肿瘤比较少见,其与成人不同在于起源多为间叶组织。文献中虽有各类肉瘤的个案报道,中耳恶性间叶瘤则为罕见,据国外此类肿瘤的报告,仅有发生在头颈部的总共20例,无1例发生在中耳。我院1982年收治1例左侧中耳恶性间叶瘤,现报道如下: 丁××,女性,11岁,因左耳疼痛两个月就医,检查发现在外耳道后壁红肿,以抗生素治疗无效,行肿块切除术,在某医院病理诊断不明。一个月后复发,来本院就诊。
Primary malignant tumors in the middle ear are rare in children, which differ from adults in that the origin is mostly mesenchymal tissue. Although there are reports of various types of sarcoma in the literature, malignant mesothelioma in the middle ear is rare. According to the reports of such tumors in foreign countries, only 20 cases occurred in the head and neck, and none occurred in the middle ear. In our hospital in 1982, one case of malignant mesothelioma of the left middle ear was treated and reported as follows: Ding × ×, female, 11 years old, suffered pain from the left ear for two months. The examination revealed that the posterior wall of the external auditory canal was red and ineffective. The lumpectomy was performed and the pathological diagnosis was unknown in a hospital. After a month of recurrence, come to our hospital.
