Type of Preparation:
ThinPrep/ LBP


NILM: Squamous Metaplasia

Cytomorphologic Criteria:
Rounded up cells with somewhat higher N/C ratio but smooth nuclear contours and even distribution of chromatin.

Explanatory Notes:
Squamous metaplastic cells round up in liquid based preparations. Instances in which there is a higher N/C ratio (>50%) in conjunction with hyperchromasia and/or nuclear contour irregularities such as notching or grooving could prompt the consideration of HSIL or ASC-H.
