Interpretation:
NILM: Histiocytes

Cytomorphologic Criteria:
Streaming pattern of single cells with round, ovoid, and bean-shaped nuclei. These cells are histiocytes with eccentric round to oval nuclei and foamy cytoplasm.

Explanatory Notes:
These cells possess fine cytoplasmic vacuoles that may resemble degenerative vacuoles sometimes found in normal metaplasia, ASC-H, and HSIL. Typically, cells of squamous lineage are polygonal in shape and possess dense cytoplasm. (Compare with ASC-H and HSIL in mucus).
