Male germ cell tumors (GCTs) are predominantly derived from testis, while about 2-5% of which arise at extragonadal
Gonadal and extragonadal
germ cell tumours in the United States, 1973-2007.
The prevascular compartment is the most common location for an extragonadal
germ cell tumor and accounts for 6-18% of mediastinal masses in children.
The following case from our institution was also included in the analysis: a 25-year-old male with extragonadal
germ cell tumor and residual postchemotherapy lymphadenopathy who underwent combined resection of an anterior mediastinal mass and extensive retroperitoneal lymph node dissection.
Trials of new germ cell immunohistochemical stains in 93 extragonadal
and metastatic germ cell tumors.
Breed and seasonal variations in the testicular morphometry, gonadal and extragonadal
sperm reserves of the barred plymouth rock and Nigerian indigenous breeds of the domestic fowl.
1) It arises mainly from trophoblastic germ cells and is usually of endometrial origin but may be extragonadal
Ovarian teratomas in livestock are rare neoplasms of germ cell origin and are most commonly localized in the gonads, both ovaries and testes; although, extragonadal
teratomas have been described (SCHLAFER & MILLER, 2007).
Risk factors for testicular cancer include cryptorchidism (testicular maldescent), carcinoma in situ (intratubular germ cell neoplasia), history of testicular cancer or extragonadal
germ cell tumor, family history, HIV infection, Down syndrome, and testicular trauma.
Typically, large-yolk protein precursors are synthesized in extragonadal
tissues (Wallace and Selman, 1981; Voogtet al.
germ cell tumours (GCTs) are uncommon and represent 2% to 5% of adult germ cell malignancies.
En la estancia el paciente fue valorado por oncologia quienes documentan un tumor germinal tipo seminoma extragonadal
, le hacen una nueva tomografia que documenta una masa del mediastino anterior, con infiltracion a pericardio, contacto con la arteria pulmonar y con la vena que drena el lobulo superior izquierdo.
