Paediatric vulvovaginitis.

Vulvovaginitis in the prepubertal child may present with itch, irritation, pain, dysuria or discharge as a result of poor hygiene, contact irritants, sexual abuse or skin disease involving the genital area. Common infectious causes include threadworms, group A beta-haemolytic streptococci and Haemophilus influenzae. A full history and examination are essential. Investigations may include swabs, midstream urine, biopsy, ultrasound and examination under anaesthesia.
