Expression of SALL4 and SF-1 in gonadoblastoma: useful markers in the identification of the invasive germ cell component.

Abstract excerpt

Gonadoblastoma is a rare gonadal neoplasm composed of primordial germ cells and sex cord-stromal cells and usually occurs in patients with dysgenetic gonads. When patients with gonadoblastoma develop an invasive germ cell tumor, the invasive germ cell component can take the form of dysgerminoma/seminoma, embryonal carcinoma, or yolk sac tumor.
