Vulvovaginal enterobiasis is underreported and an often-missed diagnosis in prepubertal girls presenting with isolated nocturnal vulvar pruritus. An 8-year-old-girl with intense nocturnal vulvar itching for 4 months was diagnosed with enterobiasis after microscopy of a vaginal swab revealed Enterobius vermicularis (pinworm) ova. The child and her family were treated with two doses of oral albendazole, 2 weeks apart, resulting in symptom resolution. This case highlights the importance of considering enterobiasis as a differential diagnosis for nocturnal vulvar pruritus to prevent delayed treatment.
