Endodermal sinus tumor or orchioblastoma in children and adults
Copyright policy )Endodermal sinus tumor or orchioblastoma in children and adults
19 “endodermal sinus tumors” of infantile testes and 5 analogous testicular tumors in adults were studied. The histopathology and prognosis of these cases are shown. As Teilum postulated, the “endodermal sinus tumor” should be a unilaterally developed teratoma mimicking embryonal yolk sac tissue. The histology seems to confirm that this tumor type is of teratomatous genesis. In one tumor specimen two dermoid cysts were found. Despite the characteristic morphology of the tumor tissue a histogenetic interpretation is not yet possible. A comparison of human embryonal yolk sac does not show any similarity to the tumor tissue. The term EDST is therefore not appropriate.
