下咽癌连续大切片的病理学观察

Pathologic histology study on the continual complete sections of inferior pharyngeal carcinoma

目的:探讨下咽癌不同类型与其浸润部位。方法:对7例下咽癌进行连续大切片,常规石蜡切片,HE、 Mallory三色染色法,光镜观察。结果:不同类型下咽癌浸润部位有一定差别。结论:对下咽癌浸润范围的 研究对于手术范围确定和保留喉功能非常重要。

Objective : To explore the relationship between various types of inferior pharyngeal carcinoma and their infiltrative sites. Methods : Microtomy of regular paraffin embedding was performed in 7 cases of human inferior pharyngeal carcinoma . The sections are continual complete ones,which were stained by HE staining and 3 colours staining of Mallory's and were observed by light microscope. Results; Certain extent infiltrative sites of inferior pharyngeal varies with the different types. Conclusions: It is very important for determining scope of operation and retaining laryngeal function as much as possible to study the infiltrative range of inferior pharyngeal carcinoma.
