title: Infantile endodermal sinus tumor presenting with vaginal bleeding: report of a case.
abstract: Endodermal sinus tumor (EST) of the vagina is extremely rare and primarily affects infants. We report on a six-month-old female infant with EST of the vagina who presented with vaginal spotting of one month's duration. Pelvic ultrasound and computerized tomography showed a 3.8 x 3.5 cm heterogeneous mass between the bladder and the rectum. The serum alpha-fetoprotein (AFP) level was high (1270 ng/mL) and the beta-human chorionic gonadotropin was undetectable. She received surgical intervention followed by chemotherapy. The patient was disease-free and serum AFP remained undetectable during the eight-month follow-up period.
