Mild squamous epithelial hyperplasia usually refers to a proliferative change in the overlying squamous epithelial mucosa with a mild disturbance in cell polarity due to long-term chronic inflammatory stimulation or bacterial or viral infection. In this case, it is usually an inflammatory lesion or a benign lesion and patients are advised not to worry excessively. It can be cured with clinically effective regular treatment, and patients are advised to review regularly and follow up closely. In clinical practice, mild squamous epithelial hyperplasia can be manifested as many kinds of diseases as follows: 1. For example, in esophagitis, squamous epithelial hyperplasia or papillary hyperplasia changes in esophageal mucosa caused by the stimulation of chronic inflammation or viral infection, and in cervicitis if mild squamous epithelial hyperplasia is diagnosed, patients are advised to have regular cervical cytology TCT combined with HPV virus testing so as to prevent the occurrence of cervical cancer. In addition, there are also proliferative changes of squamous epithelium in the vulva and skin, for example, mild hyperplasia is reversible as long as it is treated regularly. 2. Another part will develop into severe or malignant, while severe hyperplasia has a high chance of becoming cancerous. Therefore, patients are advised to treat actively and follow up closely for early detection and treatment to avoid aggravating the disease.
