表皮及附件在胚胎发育过程中均源自外胚叶,故在肿瘤的发生上可以归为一大类。对于其肿瘤及瘤样病变大批的病理统计分析,国内尚缺少。为此,本文就本教研室近20年(1962～1981)来病理活检中的3,667例表皮及其附件的肿瘤及瘤样病变统计分析如下。 一、良性瘤及瘤样病变 在3,667例中,良性瘤及瘤样病变2,379例,占64.9%。按其组织分化表现,分表皮瘤及附件瘤两大类:
The epidermis and appendages are all derived from the epiblast during embryonic development and can therefore be classified as a major class in the occurrence of tumours. For a large number of histopathological statistical analysis of tumors and tumor-like lesions, the domestic is still lacking. For this reason, the statistical analysis of the 3,667 cases of epidermis and its attachments in pathological biopsy in the current teaching and research section in the past 20 years (1962-1981) was carried out as follows. First, benign tumors and tumor-like lesions In 3,667 cases, benign tumors and 2,379 cases of tumor-like lesions, accounting for 64.9%. According to the performance of histological differentiation, divided into two categories: epidermoma and adnexal tumors:
