“The term “cervical erosion” has been used in obstetrics and gynecology to diagnose chronic cervicitis for more than a hundred years, since 1850 to the 1980s of the last century. With the progress of medical science, especially in the past 10 years, in-depth research on the etiology and pathogenesis of cervical cancer and its precancerous lesions. A large number of evidence-based medical research results obtained worldwide have shown that persistent infection (at least for more than 2 years) with about 15 types of oncogenic human papillomavirus (HPV) is closely related to the development of cervical cancer and its precancerous lesions. Celiac disease, which was once thought to be related to cervical cancer, is now thought to be unrelated to the development of cervical cancer. In the 1980s, the American monographs and textbooks on obstetrics and gynecology deleted the term “cervical erosion” and replaced it with “cervical ectopy”. Our country also in recent years revised the publication of obstetrics and gynecology textbooks will be discarded. Unfortunately, to date, a significant number of obstetricians and gynecologists in China continue to use the term “cervical ectopy,” providing unnecessary treatment and possible harm to women who have “cervical ectopy” but no cervical disease. The essence of “celiac disease” is cervical ectropion. Domestic textbooks used to describe “celiac disease” as a congested, reddened, granular appearance of the outer cervix. There are two types of cervical epithelium during embryogenesis: primitive squamous epithelium and columnar epithelium. Before puberty, the primitive squamous-columnar junction is located anywhere within or outside the cervical canal or the vaginal vault. After puberty, under the influence of estrogen, the cervix grows rapidly and greatly exceeds the body of the uterus, and cervical ectropion occurs. Ectropion exposes the columnar epithelium of the cervix to the ectocervix, which is “red and rough”: red because the columnar epithelium is arranged in a single layer with a rich network of blood vessels underneath; rough because the columnar epithelium is fused with each other in the form of villi or granules. In the past, the term “celiac disease” was used to describe the “red roughness” of the ectocervix, which was mistakenly described as “loss of the overlying epithelium”, which is an inappropriate and erroneous terminology that should be abandoned. The essence of “celiac disease” is cervical ectropion, a physiological phenomenon that lasts for decades from puberty.
