根据安德森医院自1944至1977年间的统计,外耳恶性黑素瘤占头颈部原发性黑素瘤的7%,占耳部皮肤癌的4%。作者们搜集了该时期到该医院就诊的102例患者,均经活检证实为恶性黑素瘤,每个患者至少被随诊2年或直至死亡。本组患者年龄最小8岁,最大83岁,平均年龄56岁。75%的患者是男性;63%的患者其主要职业在户外工作。本组没有黑人患者。病变部位:耳屏12例;耳甲6例;耳轮60例;耳垂24例。耳部淋巴引流主要注入下述几组淋巴结;(1)耳周围,包括耳前和耳后淋巴结;(2)腮腺淋巴结和(3)上颈或颈二腹肌淋巴结。无一例表现有下颈淋巴结的转移。临床有肯定淋巴结转移者42例,其生存率分别为:1年80%,2年60%,5年12%和10年10%。60例无淋巴结转移者的生存率是:1年 According to the Anderson Hospital’s statistics from 1944 to 1977, malignant melanoma of the external ear accounted for 7% of primary melanoma of the head and neck and 4% of skin cancer of the ear. The authors collected 102 patients who visited the hospital during this period and all were confirmed by biopsy as malignant melanoma. Each patient was followed up for at least 2 years or until death. This group of patients was the youngest 8 years old, the largest 83 years old, the average age of 56 years. 75% of the patients were male; 63% of the patients had their main occupation working outdoors. There are no black patients in this group. Lesions: 12 cases of tragus; 6 cases of ear; 60 cases of helix; 24 cases of ear lobe. Lymphatic drainage of the ear mainly injects the following groups of lymph nodes: (1) Around the ear, including the preauricular and postauricular lymph nodes; (2) parotid lymph nodes and (3) upper cervical or cervical digastric lymph nodes. None showed a metastasis of the lower cervical lymph nodes. There were 42 patients with positive lymph node metastasis, and the survival rates were 80% in 1 year, 60% in 2 years, 12% in 5 years and 10% in 10 years. The survival rate of 60 patients without lymph node metastasis is: 1 year
