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


Clinical History:
32 year old with "vaginal discharge"

NILM: Trichomonas vaginalis

Cytomorphologic Criteria:
Trichomonas is a pear-shaped, oval to round, cyanophilic organism that ranges in size from 15-30 microns. The nucleus is pale, vesicular and centrally located. Eosinophilic granules are often visible in the cytoplasm. In LBPs, the organisms tend to be smaller due to rounding, nuclei and cytoplasmic granules are better visualized and flagellae are often better preserved.

Explanatory Notes:
Good example of a flagella. Flagella are usually not seen in conventional Pap smears. Also seen in this image (left lower inset) is a "kite shaped" trichomonad- another finding noted in liquid based preparations.
