原发于宫颈柱状上皮的腺癌占所有宫颈癌的10%。一般在组织学检查对,大约所有宫颈腺癌的8%还是原位癌。最近Boon 等人回顾研究了5例在最初宫颈活检时漏诊的宫颈原位腺癌,他们强调原位腺癌在3～7年后可能发展为浸润型腺癌。因此,宫颈原位腺癌的脱落细胞学侦察是所有诊断细胞学室的重要任务. The primary adenocarcinoma of the cervical columnar epithelium accounts for 10% of all cervical cancers. Generally in histological examination, about 8% of all cervical adenocarcinomas or carcinoma in situ. Recently, Boon et al. Reviewed 5 cases of adenocarcinoma of the cervix that had been misdiagnosed during the initial cervical biopsy. They emphasized that in situ adenocarcinomas may develop invasive adenocarcinomas 3 to 7 years later. Therefore, exfoliative cervical cytology in situ cytology is an important task in all diagnostic cytology rooms.
