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.enendodermal sinus tumor, infantile, vaginal[SDGs]SDG3journal article75172452-s2.0-0028330257https://api.elsevier.com/content/abstract/scopus_id/0028330257
