In trichomoniasis, the vulva may appear erythematous and edematous, with excoriation. Look for a copious, frothy, homogeneous vaginal discharge that can be white, gray, yellow, or green. Small punctate cervical and vaginal hemorrhages with ulcerations may be observed. So-called strawberry cervix, or colpitis macularis, is highly specific for Trichomonas infection, and 2-5% of patients will have this finding on examination.

Because diagnosis of Trichomonas infection on the basis of clinical signs and symptoms is unreliable, laboratory confirmation is mandatory.
