malignant germ-cell tumors (mgct) are rare tumors of childhood accounting for less than 3% of pediatric malignancies. endodermal sinus tumor (est) forms the most common histologic subtype of mgct. the vagina is an extremely rare site for gcts. an 8-month-old female was admitted with a short history of vaginal bleeding, and a mass protruding from the vagina. she was pale and a mass was palpable ...

Endodermal sinus tumor (or Yolk Sac tumor) of the vagina is a rare malignant germcell tumor which is seen exclusively in children younger than 3 years of age. We report two cases of endodermal sinus tumor of the vagina. In both cases no radiological investigation was done and serum alpha-fetoprotein was elevated. The histopathological examination of both the tumor masses revealed vaginal endode...

The aim of this study was to evaluate the conservative management and prognosis of primary vaginal endodermal sinus tumor and rhabdomyosarcoma in children. Medical records of children with vaginal endodermal sinus tumor and rhabdomyosarcoma between 1996 and 2015 were reviewed. A total of 24 patients (median age, 12 months; range, 7-44 months) were included in this study, comprising 17 patients ...

AIMS To investigate a potential diagnostic use of alpha fetoprotein (alpha FP) isoform analysis by lectin affinity electrophoresis to distinguish between endodermal sinus tumours arising in the vagina in infants from those at other sites. METHODS alpha FP in the serum of a patient with a vaginal endodermal sinus tumour was analysed for its isoforms by lectin affinity electrophoresis. The isof...

Calcified peritoneal implants have been attributed to various malignant and benign causes. We present an interesting case of a 32-year-old woman who presented with abdominal pain, distension and vaginal bleeding. Contrast-enhanced computed tomography revealed calcified peritoneal implants with a malignant ovarian mass. Histopathology showed an endodermal sinus tumor, a rare cause of calcified p...

Malignant germ-cell tumors (MGCT) are rare tumors of childhood accounting for less than 3% of pediatric malignancies. Yolk sac (endodermal sinus) tumor is one of the malignant germ cell tumor that usually involves the gonads (ovaries and testes). Its occurrence in the vagina is extremely rare. We report a 6-months old girl presented with a vaginal mass diagnosed as a yolk sac tumor. This diagno...

ovarian mixed germ cell tumors consisting of endodermal sinus tumor and immature teratoma are very rare and have been reported only in a few case reports. here we report a rare mixed germ cell tumor of ovary which was consisted of endodermal sinus tumor and immature teratoma components with an unusual intraabdominal location. patient was a 21 years old girl with the chief compliant of abdominal...

Two cases of vaginal endodermal sinus tumor (EST), a rare pediatric malignancy, were managed with conservative surgery followed by adjuvant chemotherapy. The first case involved a 9-month-old girl with EST of the vagina, who was treated with a partial vaginectomy and VAC regimen (vincristine, actinomycin D, cyclophosphamide) during a 2-year period. The serum alpha-fetoprotein (AFP) level return...

   Malignant germ-cell tumors (MGCT) are rare tumors of childhood accounting for less than 3% of pediatric malignancies. Endodermal sinus tumor (EST) forms the most common histologic subtype of MGCT. The vagina is an extremely rare site for GCTs. An 8-month-old female was admitted with a short history of vaginal bleeding, and a mass protruding from the vagina. She was pale and a mass was palpab...
