Type of Preparation: Conventional Magnification: High Interpretation: 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. Explanatory Notes: Seen in this image are numerous trichomonads adhering to a squamous cell. Identification of one or more of the following- the organisms nucleus, cytoplasmic eosinophilic granules, or flagella (less often seen in conventional smears) is necessary in order to distinguish trichomonads from cytoplasmic fragments.
