Leukoplakia is a precancerous white lesion, but more serious lesions include the red-colored erythroplakia which almost always contain severe dysplasia or early cancer.

Erythroplakias are more serious than leukoplakia because almost always when they are removed and examined under the microscope they will show severe dysplasia, or early cancer.

黏膜斑要比黏膜白斑严重得多，因为在显微镜下观察这些组织时，它们几乎都表现出了明显异型，或变早期征象。

Normally, this ratio should be less than 40%, but it can be over 40% for people with chronic bronchitis, because of the hyperplasia and hypertrophy of the glands.

在显微镜下，活检如果显示是正常小肠细胞，并且有炎症征象，这就是非异型Barrett食管，而患食管风险很低。

Whatever the irritants are, their effect is to stimulate hypertrophy and hyperplasia of the mucinous glands in the main bronchi, as well as the goblet cells in the smaller airways - the bronchioles, which increases mucus production in both locations.

Later, realizing that the suggestion had been a poor one, and moreover one of which he was not certain, he amended the statement, adding that such a formation could also be the result of injury or simple irritation to the joint.

后来，他意识到这样推断不恰当，更何况他对此并没有把握，于是改口补充说，这样也可能是关节受伤或者仅仅是关节不适结果。
