Squamous cell carcinoma (41 cases) represented 45% of all neoplasms of the ear that were treated in the study period from 1964 to 1975. The auricle was the primary site in 17 cases, and the external auditory canal was the primary site in the remaining 24 cases. Although the overall histologic appearance and differentiation were similar in both sites, there were important age, six, and prognostic differences. Tumor-related deaths occurred in only 6% (1/17) of patients with auricular neoplasms, in contrast with 52% (11/21) of those with carcinomas of the external auditory canal. Actinic damage of the epidermis was uniformly associated with squamous cell carcinomas of the auricle, but no such relationship existed for the lesions of the auditory canal.
鳞状细胞癌（41例）占1964年至1975年研究期间所治疗的耳部所有肿瘤的45%。耳廓是17例的原发部位，其余24例的原发部位是外耳道。尽管两个部位的总体组织学表现和分化相似，但在年龄、性别和预后方面存在重要差异。耳廓肿瘤患者中仅有6%（1/17）发生与肿瘤相关的死亡，而外耳道癌患者的这一比例为52%（11/21）。表皮的光化性损伤与耳廓鳞状细胞癌始终相关，但外耳道病变不存在这种关系。
