Atlas Interpretation:
Type of Preparation:
Conventional
Magnification:
High
Clinical History:
43 year old, routine smear
Interpretation:
NILM: Tubal metaplasia
Cytomorphologic Criteria:
Columnar endocervical cells may occur in small groups or pseudostratified, often crowded groups. Nuclei are round to oval and may be enlarged, pleomorphic and hyperchromatic Chromatin is evenly distributed and nucleoli are usually not seen. N/C ratio can be high. The cytoplasm can show discrete vacuoles or goblet cell change (seen here).
Explanatory Notes:
Tubal metaplasia is a normal phenomenon in endocervical canal and includes ciliated columnar cells, peg cells and goblet cells. It is important to recognize that enlarged and/or crowded nuclei and nuclear stratification may lead to an interpretation of atypical endocervical cells unless terminal bars and cilia are identified.
