Vaginal Bleeding in Pre-pubertal Females.

STUDY

OBJECTIVE

Puberty is a normal process for adolescents, and the first signs may include change in body odor, breast development, or pubic hair growth. This is then followed by menarche approximately 2 years later. Vaginal bleeding in pre-pubertal female individuals is rare. The aim of this study was to investigate causes of pre-pubertal bleeding in a group of patients.

DESIGN, SETTING, METHOD, AND MAIN OUTCOME MEASURES: Seventeen patients who presented with pre-pubertal recurrent vaginal bleeding with no other signs of precocious puberty were investigated, to determine the cause of this symptom.

RESULTS

The mean age for the onset of vaginal bleeding was 7.4 years, ranging from 4 to 9.67 years. Gonadotrophin-releasing hormone (GnRH) stimulation tests showed a pre-pubertal response in all cases. Pelvic ultrasound scans showed a pre-pubertal uterus in all patients. Two patients were found to have foreign bodies identified during a genital examination under anesthetic, and in both cases removal of the foreign bodies terminated the vaginal bleeding.

CONCLUSION

In conclusion, recurrent vaginal bleeding was not associated with GnRH response, raised estradiol levels, or abnormal pelvic ultrasound findings. In cases of recurrent vaginal bleeding with normal hormonal investigations in pre-pubertal girls, it is recommended that a genital examination under anesthetic be undertaken to rule out undiagnosed causes of the presenting symptom.
