采用临床和组织学方法常难以把早期癌与癌前病变区别开来。本研究的目的是弄清楚舌早期浸润癌的组织学特点。材料和方法对31例舌早期浸润癌(EICT)作组织学分析和早期浸润性表现分类。检测20例无口腔疾患尸解标本舌粘膜钉突顶端到肌层间的距离并作为对照。9例EICT作三维分析,用投影机将受检各个区域的轮廓投照到薄绘图纸上,放大125倍,然后再转绘到纸上,将这些图纸重叠起来,根据Takahashi绘图法用轮廓线画出三维结构。结果细胞异形性不明显,即使在浸润部位,病理
Using clinical and histological methods is often difficult to distinguish early cancer from precancerous lesions. The purpose of this study was to clarify the histological features of early infiltrating carcinoma of the tongue. Materials and Methods Thirty-one patients with early infiltrating carcinoma of the tongue (EICT) were classified for histological analysis and early invasive performance. The distance between the tip of the nail of the lingual mucosa of autopsy specimens without oral disease and the distance between muscle layers was measured and used as a control. Nine cases of EICT for three-dimensional analysis projected the contours of each area examined onto thin drawing paper, zoomed in 125 times, and then transferred to paper, overlapping the drawings, using contour lines according to Takahashi drawing method. Draw a three-dimensional structure. As a result, the cell heterogeneity is not obvious, even at the site of infiltration, pathology
