Extragonadal germ cell tumors.
Germ cell cancer is the most common malignancy in men aged 15–35 years; 5% of the malignant germ cell tumors are of extragonadal origin [1]. An extragonadal germ cell tumor (EGGCT) is by definition a germ cell neoplasm displaying one of the histologies associated with gonadal origin, but located outside of the gonads. This specific clinical entity was first described in the 19th century [2, 3]....
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-...
متن کاملMale Extragonadal Germ Cell Tumors of the Adult.
Male extragonadal germ cell tumors (EGCTs) are characterized by a malignant transformation of germ cells without the presence of a gonadal primary tumor. EGCTs represent up to 5% of all germ cell tumors (GCTs) with an incidence around 1/1,000,000. It is assumed that EGCTs either derive from a malignant transformation of germ cells that were misdirected during embryogenesis, or from germ cells t...

متن کاملPositron emission tomography and clinical predictors of survival in primary extragonadal germ cell tumors.
BACKGROUND Primary extragonadal germ cell tumors (EGTs) are an uncommon malignancy -accounting for 2-4% of all germ cell neoplasms in adult males. Their prognosis is worse than that for testicular germ cell tumors because of their relative chemoresistance and frequent presentation with widely disseminated metastases. We have studied the role of fluorodeoxyglucose positron emission tomography (F...
