本文分析456例鼻部皮肤癌,以观察这种肿瘤的自然病史及治疗结果。年龄及性别:1％发于30岁之前,52％发于50～70岁的病人。在两性及各年龄组中,各种癌的发生率基本相同。鳞癌稍多发于男性,最常见的病因为晒太阳过多及表浅的放射治疗。本组会诊者41例,故实际经治疗者为415例。组织形态:87％为基底细胞型,常发于鼻根、鼻梁及鼻翼。鳞癌占10.7％,多发干鼻小柱及鼻侧部。其余2.3％为基底鳞状细胞癌、黑色素癌、恶性雪旺氏瘤及汗腺腺癌。很显然,鼻部对黑色素瘤、腺癌及鳞癌具有较高的免疫力。分析760例失颈部黑色素瘤,只有6例发源于鼻部皮肤。 This article analyzes 456 cases of nasal skin cancer to observe the natural history of this tumor and treatment results.
