Transverse vaginal septum. A case report.

A case occurred of imperforate, complete transverse vaginal septum in the lower third of the vagina. The patient presented at 16 years of age with primary amenorrhea and was found to have hematocolpos. The clinical impression was an imperforate hymen because of the very low position of the septum in the vagina. After excision the diagnosis of transverse vaginal septum was made histologically because of the presence of müllerian duct (mesodermal origin) tissue in the septum. The patient also had syndactyly of the second and third toes on her right foot. The association of these two congenital abnormalities has not been reported previously.
