A 19-year-old woman presents to the physician’s office for the evaluation of an
itchy vaginal discharge that she has had for about a week. She has had no fever,
abdominal pain, or dysuria. She became involved with a new sexual partner

speculum you see a bubbly, thin, yellow vaginal discharge. Her cervix is
erythematous but without discharge. She has no cervical motion or uterine or
adnexal tenderness. A wet mount of the vaginal discharge examined
microscopically reveals numerous motile, flagellated, pear-shaped organisms
along with numerous white blood cells.
