Isolated Vaginal Bleeding Before the Onset of Puberty

Abstract

Isolated vaginal bleeding before the onset of puberty is a rare presentation of isosexual precocity. In most cases, isolated vaginal bleeding without an abnormal genital examination is self-limited with resolution usually within 1 to 3 episodes. Watchful waiting is appropriate in most patients who do not have persistent bleeding, other signs of puberty, or signs/symptoms of an underlying etiology. Workup for patients with concerning features may include puberty hormone levels and/or transabdominal and transperineal ultrasound.
