Radiology of primary intracranial yolk-sac (endodermal sinus) tumors.
Most primary intracranial germ-cell tumors are germinomas and teratomas. Less frequent are embryonal carcinomas, choriocarcinomas, and yolk-sac (endodermal sinus) tumors in various admixtures and degrees of purity. Teilum [1] first used the term endodermal sinus tumor in 1959 to describe those tumors (whether ovarian, testicular, or extragonadal) that originate in primitive germ cells of extrae...
متن کاملفراوانی بروز مارکر گلیپیکان 3 (GPC3) در تومورهای سلول زایای بیضه
Background and purpose: Germ cell tumor is the most common malignancy of men between 15-34 years of age. Proper treatment is highly dependent on accurate histologic diagnosis, and different markers such as cytokeratin, CD3, GPC3 and etc. were proposed. It was reported that GPC3 is over expressed in testicular germ cell tumors by micro array assay. The aim of this study was to evaluate the expre...
متن کاملYOLK SAC TUMOR OF VAGINA
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...
متن کاملMixed Germ Cell Tumor with Extensive Yolk Sac Tumor Elements in the Frontal Lobe of an Adult
Intracranial nongerminomatous germ cell tumors (NGGCTs) in unusual locations are extremely rare. Here, we report a case of a yolk sac tumor in the frontal lobe in a middle-aged patient. A 42-year-old man was admitted to our hospital for headache and nausea. Magnetic resonance imaging (MRI) showed an enhanced mass lesion with a marked cyst component. The serum alpha-fetoprotein (αFP) level was e...
متن کاملShould extragonadal germ cell tumors be included in studies of families with testicular germ cell tumors?
BACKGROUND Family history is among the few established risk factors for testicular germ cell tumor (TGCT). Approximately 1.4% of newly diagnosed TGCT patients report a positive family history of TGCT. Sons and siblings of TGCT patients have four- to six fold and eight- to tenfold increase in TGCT risk, respectively. In twins of men with TGCT the relative risk of testicular cancer is 37.5 (12.3-...
