过去关于毛源性肿瘤的报告在皮肤附属器肿瘤中最为少见,其分类、命名也很混乱,主要原因是由于人们对此类肿瘤缺乏认识,往往误认为其他肿瘤。近年来对毛源性肿瘤的研究虽有不少进展,但到目前为止,对其分类、命名和形态学等方面的意见仍不很一致;国内对毛源性肿瘤亦缺乏比较系统的研究,许多地区仍沿用旧的不恰当的分类和命名,在诊断上也存在不少问题。为 In the past, reports on hair-derived tumors were the most rare among skin adnexal tumors. The classification and nomenclature were also very confusing. The main reason was that due to lack of understanding of such tumors, people often misunderstood other tumors. Although there have been many advances in the study of hair-derived tumors in recent years, opinions on the classification, nomenclature, and morphology of these tumors have not been consistent so far; domestically, hair-derived tumors also lack systematic research. Many areas still use the old inappropriate classification and naming, and there are also many problems in the diagnosis. for
