Prepubertal Distal Longitudinal Vaginal Folds

Prepubertal distal longitudinal folds are common, and disappear probably by spreading out during puberty with the physiologic estrogenic widening and lengthening of the vagina. This can occur because the folds do not have a dense fibrous core. The folds may be confused with the vaginal rhabdomyosarcoma or sexual molestation if the fold reaches the hymen, and forms a “bump”. The folds are benign.
