A 4-year-old female with no significant past medical history is brought to the Emergency Department by her grandmother for concern for two days of progressive vaginal bleeding. The grandmother first noted blood in the patient’s underwear the previous morning when she was helping the patient wipe and she noticed it again prior to arrival, this time saturating the patient’s underwear. There is no history of any recent falls or trauma, abdominal pain, pain to the vagina, dysuria, prior incidents of vaginal bleeding, or any noticeable behavioral changes per the grandmother. The patient lives at home with her mother but has been at her grandmother’s house for the past four days (the household consists of female cousins, grandmother, and grandfather). Of note, the patient’s father took her to a trampoline park with her younger sister two days ago.
