cervical leukoplakia
Introduction
Introduction to cervical leukoplakia Leucoplasia of thecervix refers to a gray-white opaque plaque lesion that appears in the ectocervix of the cervix. Most scholars believe that the white spots seen by the naked eye only indicate different degrees of epithelial hyperplasia. With the in-depth study of cervical precancerous lesions and early cancer and the wide application of colposcopy, this disease has gradually attracted attention. In general observation, it can be seen that there are white opaque patchy areas on the surface of the cervix. The size and shape are different. Generally, the lesions are small, the diameter is less than 1cm, and single or multiple appearances. In some cases, the leukoplakia can transcend the cervix to reach the vaginal vault. The surface is Grayish white or slightly brighter than the surrounding pink mucous membrane, the edges are neat, the boundaries are clear, and some are not neat, the surface of the white spot is easily wiped off with a cotton swab, and the bottom is spotted. basic knowledge The proportion of illness: 0.028% Susceptible people: good for adult women Mode of infection: non-infectious Complications: cervical erosion, cervical valgus
Cause
Cervical leukoplakia
The cause of cervical leukoplakia is not well understood and may be related to the following factors:
(1) Endocrine disorders: The estrogen content in the body is increased, resulting in abnormal keratinization of the surface epithelium of the cervix.
(2) Local irritation: such as chronic cervical inflammation, the influence of vaginal trichomoniasis, etc. In the clinical analysis of 700 cases of cervical erosion biopsy, Zhongshan Medical University found 37 cases of cervical leukoplakia, accounting for 5.2%, which can be seen in cases of chronic cervicitis. Among them, the incidence has increased significantly.
(3) Other factors: According to the literature report, cervical leukoplakia and atypical hyperplasia, carcinoma in situ or early invasive carcinoma coexist, and the occurrence of cervical leukoplakia may be related to the carcinogenic factors of cervical cancer.
Prevention
Cervical leukoplakia prevention
Cervical smear cytology is currently the most widely implemented and most effective method of preventing cancer.
Complication
Cervical leukoplakia complications Complications Cervical erosion cervical valgus
Combined with cervical erosion or cervical valgus.
Symptom
Cervical leukoplakia symptoms common symptoms leucorrhea increased punctiform hemorrhage cervical erosion vaginal blood secretions
Simple cervical leukoplakia is asymptomatic and may naturally subside; if combined with cervical erosion or endocervical valgus, the vaginal discharge increases, or occasionally vaginal blood secretions and contact bleeding.
In general observation, it can be seen that there are white opaque patchy areas on the surface of the cervix. The size and shape are different. Generally, the lesions are small, the diameter is less than 1cm, and single or multiple appearances. In some cases, the leukoplakia can transcend the cervix to reach the vaginal vault. The surface is Grayish white or slightly brighter than the surrounding pink mucous membrane, the edges are neat, the boundaries are clear, and some are not neat, the surface of the white spot is easily wiped off with a cotton swab, and the bottom is spotted.
Examine
Examination of cervical leukoplakia
1. Local inspection:
Through careful local observation of the cervix, white plaque areas can be found, but the keratinized lesions cannot be discerned by the naked eye.
2. Colposcopy:
Colposcopy was used to observe cervical lesions.
3. Iodine test:
Since the epithelial keratinization or incomplete keratinization lacks the ability to store glycogen, the iodine is partially not colored, whereby the extent of the lesion can be found. However, the iodine test is non-specific, such as cervical erosion, valgus or precancerous lesions.
4. Biopsy:
For cervical leukoplakia, a biopsy should be performed to rule out the presence of early cancer.
Diagnosis
Diagnosis and differentiation of cervical leukoplakia
According to local inspection, iodine test and colposcopy, it is generally not difficult to make a diagnosis, but more importantly, it should be further examined after the discovery of white spots to avoid early cervical cancer with omission and leukoplakia. According to reports in the literature, various types under colposcopy White spot is an important manifestation of early cervical cancer. For example, in some 60 cases of abnormal changes seen in 105 cases of carcinoma in situ, all kinds of leukoplakia (36 cases), for cerebral leukoplakia, should be biopsy To rule out the presence of early cancer.
Different from early cervical cancer, tissue biopsy can be identified.
