耳廓癌临床少见,国内罕有报告。我院1972～1984年共收治耳鼻咽喉肿瘤704例,其中耳廓癌仅五例,五例中耳廓鳞状细胞癌3例,基底细胞癌2例。现作报道,以供参考。病例报告(见附表) 讨论:耳廓癌临床少见。以基底细胞癌和鳞状细胞癌为最多见,属于皮肤癌。其发病原因目前尚未明确。但实验和临床研究已证实有关因素可以诱发。一般认为长期日晒及接受大量紫外线的照射可致耳廓皮肤癌变,一些皮肤的增生性病变如角化病,白斑,乳头状瘤,疤痕,慢性溃疡以及长期生长的皮样囊肿,在这些病变的基础上发生癌变。本文报告的五例中有3例是局部溃疡经慢性刺激而癌变。本病以男性为多,且40岁以前少见。本文介绍的五例中男性3例,女性2
Auricular cancer is rare in clinical practice and rarely reported in China. In our hospital from 1972 to 1984, a total of 704 cases of otolaryngologic tumors were treated, including only 5 cases of auricular cancer, 3 cases of auricle squamous cell carcinoma in 5 cases, and 2 cases of basal cell carcinoma in 5 cases. The current report is for reference. Case report (see attached table) Discussion: Auricular cancer is rare in clinical practice. The most common are basal cell carcinoma and squamous cell carcinoma, belonging to skin cancer. The cause of the disease is not yet clear. However, experimental and clinical studies have confirmed that the relevant factors can induce. It is generally believed that prolonged exposure to the sun and exposure to large amounts of UV radiation can cause auricle skin cancer, some of the skin’s proliferative lesions such as keratosis, leukoplakia, papilloma, scars, chronic ulcers, and long-term dermoid cysts, in these lesions Carcinogenesis occurs on the basis of it. Three of the five cases reported in this article were local ulcerations that were chronically stimulated and cancerous. The disease is much more common in men than before age 40. This article describes five cases of males in 3 cases, females 2
