Vaginal Bleeding due to Insertion of Button Battery: A Case Report and Review of Literature

Introduction: Foreign body insertion is a common and important cause of pre-pubertal vaginal bleeding. Case Presentation: We present a three-year-old girl who referred to our clinic with abnormal vaginal bleeding without any other symptoms. The primary assessment revealed a radio-opaque round solid mass in the pelvic cavity. Following vaginoscopy, the button battery was finally removed under general anesthesia. The vagina was washed by normal saline irrigation and some necrotic tissue was evacuated. Digital rectal exam confirmed intact rectal wall. The patient was asymptomatic in the follow up and there was no sign of recto-vaginal fistula. Discussion: Vaginal bleeding in children may have various etiologies such as foreign bodies. Foreign bodies in the vagina lead to severe inflammation and result in vaginal bleeding or blood-stained and foul-smelling discharge. Other sequel may include infections, fibrosis and recto-vaginal fistula.
