对口腔及口咽部位鳞癌患者受累粘膜临床表现进行了分析。 396名患者的口腔粘膜状况分两型,A型:表现为溃疡或肿瘤形成;B型:表现为粘膜肿大,没有其它异常。发生在口咽粘膜者占38例(10％),口腔粘膜者占358例(90％),其中发生于舌占119例(30％),上牙槽及牙龈80例(20％),下牙槽及牙龈64例(16％),口底52例(13％),颊39例(10％),硬腭4例(1％)。A型粘膜鳞癌占372例(94％),见于上述所有区域;B型粘膜鳞癌占24例(6％),仅见于上、下牙槽及牙龈部位。组织学研究显示10例B型粘膜患者之上皮与肿瘤细胞间有分隔,而另2例(B型)肿瘤细胞扩展到上皮中,但
Oral and oropharyngeal squamous cell carcinoma patients involved in clinical manifestations were analyzed. The oral mucosal conditions of 396 patients were divided into two types, type A: ulcer or tumor formation; type B: swollen mucosa with no other abnormalities. Ocular oropharyngeal mucosa accounted for 38 cases (10%), oral mucosa accounted for 358 cases (90%), which occurred in 119 cases of tongue (30%), upper alveolar and gingiva in 80 cases (20%), 64 cases (16%) of alveolar and gums, 52 cases (13%) of mouth, 39 cases (10%) of cheeks and 4 cases (1%) of hard palate. A type mucosal squamous cell carcinoma accounted for 372 cases (94%), seen in all the above areas; B type mucosal squamous cell carcinoma accounted for 24 cases (6%), only found in the upper and lower alveolar and gingival parts. Histological studies showed that in 10 patients with type B mucosal epithelium were separated from the tumor cells, while the other two (type B) tumor cells spread into the epithelium, but
