Yolk sac tumor (YST) is one of the malignant germ-cell tumors (MGCT) that usually occurs in the ovaries and testes of young patients. Its occurrence in the vagina is extremely rare. We present a rare case of extragonadal YST occurring in the vaginal region. A 12-year-old girl, presented with vaginal bleeding and pain in the perineal region. Physical exam identified a limited pelvic mass, 5 x 4cm in size. Abdominal ultrasound and magnetic resonance imaging (MRI) showed a heterogeneous mass in cervico-vaginal region. The patient was taken to the surgery, where an excisional biopsy was obtained. The diagnosis of YST is confirmed by histopathology and immunohistochemistry studies. However, the tumor marker (alpha fetoprotein and BHCG) was normal. The patient was treated according to the French TGM-95 protocol. Surgery was done after chemotherapy, hysterectomy in front of the cervical invasion, with a good decline at 2 years of end of treatment.

D018240 Endodermal Sinus Tumor An unusual and aggressive tumor of germ-cell origin that reproduces the extraembryonic structures of the early embryo. It is the most common malignant germ cell tumor found in children. It is characterized by a labyrinthine glandular pattern of flat epithelial cells and rounded papillary processes with a central capillary (Schiller-Duval body). The tumor is rarely bilateral. Before the use of combination chemotherapy, the tumor was almost invariably fatal.
