值得注意的口腔癌前期病变有以下几种: 白色海绵状态多发生于口腔粘膜,较少见于其他处,常呈染色体显性遗传。出生后即出现,或到以后才明显。典型病例为口腔粘膜大部发白,凸凹不平,或呈折皱。从其临床表现及家族性分布可以确诊,如诊断有困难,可进行活检。病变特点为粘膜上皮增厚,表面不平,部分有细菌菌落。病变以棘细胞层的上部较显著,细胞呈空泡样,胞核居中,胞浆似推向周边。多数 It is worth noting that the pre-malignant lesions of the oral cavity are the following: The state of the white sponge mostly occurs in the oral mucosa, and is rarely seen in other places, and often presents as a chromosome dominant inheritance. Occurs immediately after birth, or only later. The typical case is that most of the oral mucosa is white, uneven, or wrinkled. It can be diagnosed from its clinical manifestations and familial distribution. If it is difficult to diagnose, biopsy can be performed. The lesions are characterized by thickening of the mucosal epithelium, uneven surface, and some bacterial colonies. The upper part of the spine cell layer was more prominent in the lesions. The cells were vacuolated, the nucleus was centered, and the cytoplasm was pushed to the periphery. most
