Vulvovaginitis is the most common gynecological disorder in childhood; its causes include physical and chemical irritants and a variety of infectious agents.
Group A β-hemolytic Streptococcus and Haemophilus influenzae can be self-inoculated from nose and mouth to the vulvar region.
Good hygiene is fundamental to the resolution of many pediatric vulvar conditions.
Candidal vaginitis is rare in prepubertal children and should raise suspicion of diabetes mellitus or depressed immune function.
Enterobius vermicularis (pinworms) can be a source of irritant vaginitis.
Vulvovaginitis, or inflammation of the vulva and vagina, is the most common gynecological problem in prepubertal girls and can cause anxiety in both the child and the parent.1,2,3 Symptoms may include vaginal discharge, redness, soreness, itching, dysuria, bleeding, or pain.2,3 Vulvovaginal symptoms may be caused by nonspecific irritants, specific infections, trauma, or dermatologic conditions (Table 103-1).4 Contributing factors for prepubertal girls are poor hygiene, lack of estrogenization, proximity of vagina to anus, and lack of labial fat pads or pubic hair.1,2

Aspects of a complete external genitalia exam are noted in Table 103-2. A vaginal culture should be obtained if significant vaginal discharge is present.5 Positive cultures are more likely in the clinical setting of visible vaginal discharge with moderate to severe inflammation extending beyond the introitus.6
