分析了100例结肠腺瘤的组织学改变,包括管状腺瘤61例、乳头样腺瘤23例、管状乳头样腺瘤16例,其中29例伴癌变。认为腺瘤的大小与恶变率高低有关,有乳头结构的腺瘤恶变率亦较高。分析了腺瘤上皮细胞不同程度的不典型性增生,以及癌变过程的形态特点。对高度不典型增生与原位癌提出了组织学的鉴别点及诊断标准。
The histological changes of 100 cases of colon adenomas were analyzed, including 61 cases of tubular adenomas, 23 cases of papillary adenomas, and 16 cases of tubular papillary adenomas, of which 29 cases were associated with carcinogenesis. It is believed that the size of adenomas is related to the level of malignancy, and the malignant rate of adenomas with nipple structure is also high. The atypical neoplastic epithelial cells were analyzed for different degrees of atypical hyperplasia and the morphological characteristics of the cancerous process. Histological identification points and diagnostic criteria for highly atypical hyperplasia and carcinoma in situ.
