[Possibilities of cytologic diagnosis of uterine cervix carcinoma in situ].

The feasibility of cytological diagnosis of in situ carcinoma of the cervix uteri is discussed. A revision of the histological data and a re-evaluation of the cytological slides used have suggested cytomorphological criteria for diagnosis of the following variants of carcinoma in situ: well-differentiated squamous-cell carcinoma in situ, moderately-differentiated, low-differentiated (reserve cell), adenocarcinoma in situ (endocervical and endometroid variants). A brief description of the peculiarities of cytographs of said forms of in situ carcinoma of the cervix uteri is given. Consideration of said peculiarities will improve the standards of cytological studies involved both in screening and examination of patients.
