子宫颈原位腺癌的阴道镜图像识别难点与临床处理策略OA

Cervical adenocarcinoma in situ(AIS)is the only precursor lesion of cervical adenocarcinoma,with its incidence rising steadily in recent years.However,AIS presents non-specific colposcopic manifestations.It is often misdiagnosed as immature metaplastic epithelium or low-grade squamous intraepithelial lesion(LSIL),leading to missed or delayed diagnosis.Furthermore,occult and endocervical AIS lesions are difficult to detect under colposcopy.Based on histopathological features and lesion distribution patterns,we summarize colposcopic imaging characteristics and analyze core diagnostic challenges,thereby proposing combined low-threshold multiple biopsy for acetowhite epithelium and endocervical curettage to improve colposcopists' recognition of AIS.
