Rectovulvar fistula in a child secondary to an unusual foreign body. Foreign bodies in the female genital tract are well recognized as a cause of pain, discharge, secretions, and infection. In the small child, the presence of a vaginal discharge is usually associated with either a common object which has been inserted or sexual abuse complicated by a sexually transmitted disease. A 3-year-old child presented with a recurrent labial secretion and drainage due to an unusual foreign body. It was only during a second operation that the possibility of a foreign body was entertained, and diagnostic testing was begun. A third operation permitted removal of the foreign body, a large bone probably of animal origin. The fistula tract was closed after a colostomy was performed. This represents the first reported case of a rectovulvar fistula not of a congenital nature.
