Prepubertal vulvovaginopathies.

The vast majority of prepubertal gynecologic problems fall into three categories. The most serious category includes those "things that bleed": sarcoma botryoides, trauma (including sexual abuse), vaginal foreign objects, condylomata, urethral prolapse, and single organism vaginitis. Very rarely, the clinician will see precocious menarche, metastatic Crohn's disease, vascular vulvar lesions, and factitious cases. The next category contains entities that have an abnormal appearance: ambiguous genitalia, periurethral cysts of the newborn, hymenal variants, and agglutination of the labia and vulva. Rarely, an underlying skin disorder such as lichen sclerosus, seborrhea, or atopic vulvitis will be seen. The last and most bothersome category, distinguished by its symptoms of pruritus and discharge, includes the most common types of vulvovaginitis.
