Atlas Interpretation:
Interpreted image
Type of Preparation:
ThinPrep/ LBP


Clinical History:
Routine Pap Test, 28 year old female

Adequacy Description:
NILM: Squamous metaplasia

Cytomorphologic Criteria:
Normal polygonal squamous metaplastic cells with round to oval nuclei and bland chromatin pattern. On liquid based preparations cells may appear more rounded, and nuclei may appear smaller. This would be interpreted as "NILM".

Explanatory Notes:
The presence of squamous metaplastic cells indicates that the transformation zone has been sampled (a minimum of 10 well-preserved endocervical or metaplastic cells is required for this quality indictor).
