Hovering over the speech bubbles in the lists below will reveal extra information about the adjacent term. However, clicking on links will cause you to navigate away from the current case, at which point your progress (i.e., your check marks) will be lost. If you do want more information on a subject, either open the link in a new tab or wait until you and your partner have finished the case and reviewed the check marks.

- Washed hands
- Used respectful draping
Head, eyes, ears, nose, and throat examination
- Inspection of the oropharynx
- Neck examination
- Back examination Abdominal examination
- Skin examination
The USMLE does not allow pelvic/genitourinary examination, but they allow the inguinal lymph nodes to be examined. Make sure to use respectful draping when examining the inguinal area. A full abdominal examination should also be performed to assess for signs of pelvic inflammatory disease.

Counseling and challenge
- Examinee offered
- Examinee counseled the patient on the use of latex-free condoms.
- Examinee recommended completion of HPV vaccination series.
- Examinee reacted appropriately to challenge.
Suggested response to challenge: “Eva, I can understand your concern. While I would encourage you to share as much information with your parents as you feel comfortable, I am not allowed to share any information regarding contraception, pregnancy, and sexually transmitted diseases with your parents without your consent. So everything that you tell me about your current symptoms will be kept confidential, and I promise I will not speak with your parents unless you want me to do so. Do you have any other questions?”
If a minor is seeking medical care that is related to sex (contraception, pregnancy care, or STIs) or addiction, parental consent is not required and the information has to be kept confidential. However, the minor should be encouraged to discuss their issues with their parents. See also .
- Human papillomavirus (HPV) infection: HPV infection is the most common STI in the United States. Human papillomavirus, particularly types 6 and 11, cause condylomata acuminata , painless lesions on the vulvar, cervix, urethra (rare), and/or anal region that can also lead to pruritus and tenderness. The condition can be prevented by using condoms and completing the 2- or 3-shot series of the HPV vaccination. However, the condition is not typically associated with dysuria and vaginal discharge, making a coinfection likely in this case.
- Syphilis: A chancre is caused by infection with Treponema pallidum, a bacteria that is transmitted through unprotected sexual intercourse. The condition manifests as a single red, round, and raised painless ulcer with an elevated edge on the vulva or cervix. However, the condition is often associated with inguinal lymphadenopathy, and vaginal discharge and pruritus are not typical features. An HPV infection is more likely to explain this patient's genital lesion.
- Chlamydia trachomatis infection: Several serotypes of Chlamydia cause chlamydial genitourinary infections, one of the most common STIs. It can also manifest as urethritis and vaginal infection that present with (muco)purulent vaginal discharge and dysuria, as seen in this patient. Specific serotypes of Chlamydia can also cause lymphogranuloma venereum, a painless genital lesion that manifests as a transient small papule or ulcer on the posterior vaginal wall, cervix, and/or vulva. Lymphogranuloma venereum is seen primarily in tropical and subtropical countries, although the incidence is increasing among men who have sex with men (MSM) in the US. While it is likely that this patient has a chlamydial genitourinary infection, her genital lesion is unlikely to be caused by Chlamydia.
Always consider coinfection with multiple sexual transmitted infections, which can lead to various constellations of symptoms. It is also possible that patients may also have an asymptomatic coinfection that can only be diagnosed with appropriate testing.
- Pelvic examination: to inspect the genital lesion and vaginal discharge and examine for signs of pelvic inflammatory disease.
- Rectal examination: to assess for lesions in the rectal area (e.g., often the cases in HPV infection).
- HIV test: should be performed in all high-risk patients; consent must be obtained before the test is performed.
- Rapid plasma reagin test: to test for syphilis.
- Dark field microscopy: definitive tests for detecting primary and secondary syphilis when a specimen can be obtained (e.g., exudative chancre, condyloma).
- Nucleic acid amplification tests for chlamydia and gonorrhea: to test for Chlamydia trachomatis and Neisseria gonorrhoeae infection.
- Urine dipstick, urinalysis: to assess for a UTI.
- Wet mount preparation with KOH test: to assess for different forms of vulvovaginitis (e.g., vulvovaginal candidiasis ).
Other differential diagnoses to consider
- Granuloma inguinale
- Gonococcal infection
- Vulvovaginal candidiasis
- Urinary tract infection
