角化型基底细胞癌与毛发上皮瘤细胞核DNA含量测定

Quantitative determination of DNA content and its clinicopathological significance in keratinized type of basal cell epithelioma and trichoepithelioma

利用图像分析技术对３０例角化型基底细胞癌及３０例毛发上皮瘤组织病理相似部分基底样细胞瘤块进行细胞核ＤＮＡ含量分析。结果显示角化型基底细胞癌组有异倍体１６例，毛发上皮瘤组３０例均为二倍体。前者显示了恶性生物学行为。

Image analysis technique was applied to detect the nuclear DNA content of similar portion of basal cells from keratinized type of basal cell epithelioma and trichoepithelioma. The results showed 16 of 30 specimens from keratinized type of basal cell epithelioma were aneuploid and 30 specimens from trichoepithelioma were all diploid. The former revealed the biological behavior of malignant tumor, and the latter was of benign biological behavior.
