从118例额-筛窦粘液囊肿中的40例手术标本作详细组织学检查。对上皮、粘液分泌成分、细胞浸润和淋巴样集合物上皮下结构及骨组织变化,按0～3度分级的百分比作出对比,重点探讨粘液囊肿形成的病理机制。标本中有26%病人显示急性感染,其中52%细菌培养阳性,以葡萄球菌为最常见。上皮以假复层柱状上皮居多,有些部位伴有鳞上状皮(15/40)。67%的病例有杯状细胞,其中半数伴有组织增生。和正常窦腔粘膜上皮相比,浆液粘液腺未见增加。嗜中性白细胞、淋巴细胞和浆细胞的浸润和慢性炎症程度呈正比,急性期嗜中性白细胞明显增加。79%
From the amount of 118 cases - 40 cases of ethmoid cyst in surgical specimens for detailed histological examination. The epithelial, mucus secretion components, cell infiltration and lymphoid subepithelial structures and bone tissue changes, according to the percentage of 0 to 3 degrees to make a comparison, focusing on the pathological mechanism of mucus cyst formation. 26% of the patients in the specimen showed acute infection, of which 52% were positive for bacterial culture and Staphylococcus was the most common. Epithelium mostly pseudostratified columnar epithelium, some sites accompanied by squamous epithelium (15/40). 67% of cases goblet cells, of which half with tissue hyperplasia. Compared with normal sinus mucosal epithelium, there was no increase in serous mucus glands. The infiltration of neutrophils, lymphocytes and plasma cells is proportional to the degree of chronic inflammation and acute neutrophils are significantly increased. 79%
