The presence of saprophytic cells is generally present in normal individuals and may be a normal physiological condition, but sometimes the presence of saprophytic cells may be a precursor to certain pathologies. Normal saprophytic cells are often shed by saprophytic tissue and are generally divided into immature saprophytic cells and mature saprophytic cells, which usually refer to squamous epithelial saprophytic cells. Abnormal saprophytic cells that appear, i.e. atypical squamous epithelial saprophytic cells, often have the potential for inflammation or cancer. Chemosis is an adaptive response. When a cell or tissue is injured or stimulated it will make changes, i.e., it will undergo an adaptive response and differentiate into other cells or tissues. Because this process is slow, there is a distinction between mature and immature. These two areas are susceptible to external stimulation, but when the external stimulation disappears, the chemotaxis will return, and this situation usually does not need to be treated, and regular checkups can be performed. In the process of chemosis, abnormal chemosis cells may be produced because of the stimulation of foreign substances, combined with the stimulation of bacterial and viral invasion and inflammation. Such abnormal septic cells may overproliferate and tend to cause inflammation or aggravate inflammation. A typical example is squamous epithelial metaplasia at the cervical os in cervicitis, which may lead to cervical squamous carcinoma after prolonged inflammation. In this case, surgery is required. Therefore, if abnormal metaplasia is detected, it should be treated as soon as possible.
