Malignant extragonadal germ cell tumors, though more common in infants and children, are rare. They occur in the body's midline and may have internal and external manifestations. We report a case of an 11-month-old female with sacrococcygeal extragonadal yolk sac tumor manifesting as a draining subcutaneous nodule after initial treatment as an abscess. Extragonadal germ cell tumors can present with external manifestations confusingly similar to other more benign soft tissue conditions.
恶性性腺外生殖细胞肿瘤虽然在婴幼儿中更为常见，但实属罕见。它们发生于身体中线部位，可能有内外部表现。我们报告一例11个月大的女性骶尾部性腺外卵黄囊瘤病例，最初因脓肿接受治疗后，表现为一个有分泌物的皮下结节。性腺外生殖细胞肿瘤的外部表现可能与其他更良性的软组织疾病相似，容易造成混淆。
