T. VAGINALIS TROPHOZOITES Figure 30-6 T. VAGINALIS TROPHOZOITES Liquid-based cervical cytology preparations show trophozoites between abundant neutrophils; they have small pale nuclei (A, arrows). High-power view demonstrates the ovoid to pear-shaped morphology of the parasites, which demonstrate characteristic cytoplasmic granules, “washed out” nuclei, and polar flagella (B–D).

TRICHOMONAS Figure 30-4 TRICHOMONAS Cervical cytology smears show clusters of neutrophils, reactive squamous epithelial changes (with vague perinuclear halos), and interspersed T. vaginalis organisms (arrows) (A,B). Note the nondescript appearance of the parasites against the granular smear background (C). More about this image found in TRICHOMONAS Cervical cytology smears show clusters of neu...
