Sexual Abuse as a Cause of Prepubertal Genital Bleeding: Understanding the Role of Routine Physical Examination.

Although accidental trauma is the most common mechanism for genital bleeding, sexual abuse should be considered when the patient is prepubertal and/or a vague history of bleeding is provided. Prepubertal female genital exams should be completed routinely; this clinical technique is critical for pediatricians to assess pubertal progression, to identify pathologies or differences in sexual differentiation, and to narrow a broad differential diagnosis of bleeding. Physical evidence of sexual abuse on exam is rarely found, and therefore the diagnosis relies on a child's disclosure. Physicians should be cognizant of barriers to patient disclosure. In this commentary we aim to provide general pediatricians and trainees with a framework for evaluating genital/vaginal bleeding in prepubertal girls, by discussing the following: (1) the importance of a complete anogenital exam in generating a differential diagnosis; and (2) the possibility of sexual abuse as an etiology with recognition that the disclosure process is complex.
