Nasopharyngeal Mucosa Epithelium Seen in the Biopsy Tissues
Zong Yongsheng (Shantou University Medical College)
Basing on the microscopic survey of more than 20,000 nasop- pharyngeal biopsy tissue slides,the author gives an summary description on the structure and cell types of the mucosal epithelium for the pur- pose of helping the pathologists to make diagnose and study nasopharyngeal carcinoma. The great majority of nasopharyngeal mucosa epithelium is of colum- nar type,which consists of four cell types,namely,ciliated columnar cells,mucoid cells,intermediate cells and basal cells.All these cells were described cytologically and mucin-cytochemically in detail. Most of the glands seen in the nasopharyngeal mucosa are sero-muc- inous,The structure of these glands and the characteristics of the muc- inous substances secreted by the glands were also demonstrated.
