Yolk Sac Tumor : Gross Pathology

Pure yolk sac tumors are usually soft, solid tumors with a myxoid or gelatinous quality. The cut surface is yellow-tan to greyish-white. Larger tumors may have foci of hemorrhage and necrosis or small cystic areas. In such cases, the possibility of a mixed germ cell tumor should be considered, especially in an adolescent or a young adult patient.
